LitecoinLitecoin has been making a lot of noise recently after a sharp rise in price. It could be that Bitcoin miners are finally feeling the pinch of specialized mining hardware known as ASICs. It could also be that a flood of newcomers to the crypto currency market is creating a demand not just for Bitcoin but also for Litecoin. In any event, I’ve had quite a few people asking about a basic guide for Litecoin mining so here it is.

Update 1/2/2014: This guide covers Radeon graphics cards. For a guide covering NVIDA cards check out our new Beginner’s Guide To Litecoin Minnig With NVIDIA Graphics Cards.

If you’re not yet familiar with Litecoin or don’t yet have a Litecoin wallet I suggest you check out our guide to Getting Started With Litecoin. It provides a brief overview of the currency and a tutorial for setting up a wallet.

Mining Basics

Litecoin mining is the process of using your computer’s CPU (Central Processing Unit) and GPU (Graphics Processing Unit) to process transactions for the Litecoin network. By doing this you can attempt to solve a ‘block’ which pays out a reward. Currently the Litecoin reward per block is 50 Litecoins.

Unlike Bitcoin, CPUs can still contribute enough hashing power to be significant to Litecoin, though this may quickly change. In fact, this was one of the original design features of Litecoin. Because Litecoin uses a scrypt encryption algorithm there is a much smaller efficiency gap between CPU mining and GPU mining. For this reason the Litecoin client still has a built in CPU mining program.

Another important concept of modern mining is pool mining. A mining pool is a group of miner’s that pool their resources together so that they can find blocks faster. The reward is then split between the pool members based on their contributions. This tutorial uses Coinotron mining pool along with GUIMiner Scrypt and assumes Windows 7 or 8 as an operating system.

Downloading GUI Miner Scrypt

GUIMiner Scrypt is a recently put together mining program similar to the popular and easy to use Bitcoin GUIMiner. The main difference between the two is that this GUIMiner is built with a Scrypt miner as the backend. Many other Litecoin miners such as Reaper and Cgminer (The backends for this) are more versatile but usually more difficult for beginners. For most other Litecoin mining programs you need an understanding of the command line.

In addition to GUIMiner Scrypt you’ll need to download and install the most recent drivers for your Graphics Card as well as the AMD APP SDK. If you do not have these installed you will likely get an error relating to OpenCL.

AMD Drivers Download Page

AMD APP SDK Download Page

NOTE: GUIminer Scrypt is in it’s Alpha phase and may still have bugs. Check this bitcointalk thread out for full details on the miner and know issues. Also note that because GUIMiner Scrypt includes cgminer it may be detected as malware by antivirus and malware detection programs. However, GUIMiner Scrypt does not contain malware and is safe to use. More on this in the comments.

Download GUIMiner Scrypt From Mega V0.03

GUI Miner Scrypt

Once you’ve downloaded  GUI miner scrypt you’ll need to create an account with Coinotron. As mentioned earlier Coinotron is the mining pool that we’ll be using in this tutorial. There are a lot of other Litecoin pools out there but Coinotron is one of the easier to use and offers multiple coins.

Coinotron Registration Page

Coinotron Registration

Once you’ve created an account with Coinotron navigate to the the my account page and set up a Litecoin worker (LTC) and password. This Litecoin worker and password is what you’ll be using with GUIMiner scrypt. You’ll also want to specify a payout address (i.e. your Litecoin wallet address).

Next start up GUI miner scrypt by finding the .exe file in the folder you downloaded (I usually just leave the folder on my desktop). After you’ve gotten GUI miner scrypt up and running you’ll need to enter your settings. Your GUIminer should look similar to the one below.

GUI Miner Scrypt Working


One of the nicest features of GUI Miner Scrypt is that it has built in settings for most common GPUs. Just go to the GPU Defaults tab and choose your GPU. After using their defaults I saw an increase in hash rate of about 100 kh/s.

Once you have entered all your settings click the start button and you should see a hash rate appear in the bottom right corner. If you don’t or you see an error it is probably because one or more of your settings aren’t right. Litecoin mining is much more finicky when it comes to settings that Bitcoin or Terracoin. The specific settings that you use should correspond to your particular GPU.

Where To Go From Here

At this point you should be started mining Litecoin! Just remember that this version of GUI Miner is meant to work with Scrypt coins like Litecoin. If you’re interested in Bitcoin or Terracoin our Guide To Mining Terracoin or our Guide To Bitcoin Mining.

If you’d like to get an estimate as to how many coins per day you should be earning you should check out this Litecoin mining calculator.

GUIMiner Scrypt Developer

Prior to the recent release of GUIMiner Scrypt, Litecoin mining was difficult for beginners. Once you end up getting your miners going please consider donating to BitcoinTalk user TactoTime. The original thread for GUIMiner scrypt is here at bitcointalk. The addresses are as follows:

Disclaimer About Laptops

Mining on laptops can be a bad idea. They don’t have the cooling that desktops do and this has resulted in the death of a few motherboards with Bitcoin mining. If you have a desktop-like or gaming laptop they might be better suited. However, laptops like MacBook Pros and many ultra books don’t have a way to dissipate that much heat. It can also harm some batteries.

    Im confused. When I downloaded the miner it just brought up a bunch of folders. Im not sure how to fix it. I checked out the thread but im still confused.

  2. CryptoJunky Says:

    Kenny, in the main folder you’re looking for a file called guiminer. It still has the bitcoin logo next to it, at least in this version. as for type of file it should be Application. You’ll want to open this file and it will start the GUIMiner application. Let me know if this works for you.

  3. papa Says:

    hi the version of srypt is not similar you have described

  4. Will Says:

    When I try to run it, it says:

    “Missing OpenCL.dll file

    Now how do I handle that?


  5. CryptoJunky Says:


    What model/type of card are you mining on? Most mining software requires that the card supports OpenCL, basically a parallel processing platform for GPUs. You may either have to install new/different drivers or your card might not be compatible. Post the model if you get a chance.

  6. Says:

    You need to also stress that centralized pools are constantly under attack and sometimes get so much hashing power a 51% attack is a possibility.
    You should suggest also that people mine on a p2pool. They dont have to do any setting up but point their miners to a p2p node and use their LTC address as their -u

  7. Will Says:

    It sounds like you may have underestimated just what an absolute beginner is. :-)

    model type of card?

    I am just exploring this on a Toshiba laptop. I thought I read somewhere that regular ole home computers were good with LTC.

    Thanks for your help, there are others that are as lost as I am.

  8. CryptoJunky Says:

    Up until the recent rise in difficulty of Litecoin it was regularly mined by CPUs which made it a good coin for home computers. However, you won’t earn all that much now. More serious miners are on home computers with a dedicated graphics card, an example is a high end one such as this:

    This would net you something like 7-8 Litecoin a day at the moment.

    There are a few potential problems with mining on a laptop or old home computer. First off they’re not built for the heat, especially laptops, which makes it potentially dangerous. Secondly they may or may not have the computing power necessary to make it worthwhile.

    Most low-end laptops have integrated graphics meaning that GPU mining isn’t really possible, only CPU mining. If you’re interested in giving CPU mining a try you don’t need to download the GUIMiner Scrypt program but can use the Miner built into the litecoin wallet. The miner built into the litecoin client will only use your computer’s CPU to mine Litecoin. I still recommend you join a pool like Coinotron and fill in the necessary detail.

    Let me know if this helped clarify things, if not I can put together a much simpler tutorial on CPU mining Litecoin that I think will help.

  9. Will Says:

    Yes that did help thanks.

    Still, you might consider doing a post for REAL newbs. I see questions similar to mine over at bitcointalk and I will point them to your post if you make it. Thanks.

  10. CryptoJunky Says:


    I can see how a post on CPU mining might be helpful, especially for those curious as to how early Bitcoin mining worked. I’ll work on the post but it might be a week or two until I get to it. I have a bit of a backlog at the moment and still haven’t finished my intro posts to Bitcoin.

  11. cryptorho Says:

    Can you run Guiminer-scrypt AND GUIMiner (to mine bitcoins) simultaneously on your graphics cards?

  12. CryptoJunky Says:


    The short answer is no.

    While I haven’t tried this I definitely recommend against it. They’re both using your GPU’s processing power to mine and trying to mine with both could have some very negative consequences. It will likely crash your graphics driver if nothing else.

  13. LTCLotto Says:

    Hey cryptorho,
    I run Reaper to utilize the GPU, and Scryptminer-GUI to utilize the CPU. This does seem to work OK for me and after a little bit of tweaking, neither seems to impact the other too much. Been running now for over 36 hours like this and yet to have any problems.

  14. Will Says:


    I must have downloaded a half dozen different miners trying to get one to work. “Install OpenCL.dll” this. See logfile guiminer.exe that. Folders all over my desktop. Even the microminer in the LTC wallet won’t pool.

  16. Barkzilla Says:

    Does this work on 64-bit windows or only 32? I’m having trouble installing on a Windows 7 Pro machine.

  17. CryptoJunky Says:

    I’ve been running it on 64 bit without a problem. What problem(s) are you running into?

  18. fuhoser Says:

    Thank you for the help!

  19. Barkzilla Says:

    When I attempt to run the guiminer application, I get an error log containing the following:

    Traceback (most recent call last):
    File “”, line 18, in
    File “pyopencl\__init__.pyo”, line 4, in
    File “pyopencl\_cl.pyo”, line 12, in
    File “pyopencl\_cl.pyo”, line 10, in __load
    ImportError: DLL load failed: The specified procedure could not be found.

    Don’t really know what to say other than that. The error happens as soon as I start to run the program.

  20. Carl Says:

    just imagine..if this works out… ;-)

  21. DJ Says:

    Cool tutorial. When I click start it’s stuck at “starting”… I think all the settings are right. What could be the problem?

  22. CryptoJunky Says:

    I just made a few updates to the tutorial thanks to suggestions from TacoTime, the author of GUIMiner Scrypt. Previously I had the wrong link to the Bitcointalk thread, the correct link is here:

    I also had not included links and information regarding AMD drivers and the AMD APP SDK. For those of you that have been getting errors related to OpenCL this will probably fix it. Download and install the latest drivers and APP SDK from the links below:

    TacoTime recently updated GUIMiner Scrypt to version 0.03 with fixes for known problems. The MEGA download is here:!UlskWQYC!TVod3g5m9gsHe9kU6eoQhRItYmZw-fQ_VYM8GsPTcBY

    As for GUIMiner Scrypt being detected as ‘malware’ or as a ‘virus’, it is not. Part of the package includes CGminer, the backend that actually does the litecoin mining. It is my understanding that CGMiner has been included in some malware programs in the past, for instance for using someone’s computing resources to mine. However, CGMiner is not malware but is the software that is actually doing the mining for you. Let me know if you have further questions on this. If it helps I have been running CGminer for around 6 months now without problems after ignoring malware warnings.

    Important – After you’ve mined a few Litecoin please donate to TacoTime using the addresses listed in the article. He’s put together GUIMiner Scrypt and donating a few coins will help him keep it up to date. Thanks Taco Time!

  23. CryptoJunky Says:

    DJ – sounds like either an error with your settings or you may not have the correct drivers installed. Recheck your settings and if you need reinstall drivers. If you still have problems send me a screenshot with your card model and I’ll see if I can figure it out.

    I just realized I’ve got an hd 3000.. so am screwed.

    i have an i7 though so it might be worth it for cpu mining.
    Could i suggest you to make a quick tutorial on how to use ltc client’s miner? i’ve been all day looking up the internet but cannot find anything.

  26. aminer Says:

    hi crypto, great guide but im having a few probs, be glad to send you some coins if u can help get me rolling..
    ive used scryptminer gui so have a little exp with mining ltc, had no problems with it at all
    just got a new pc dual 7970 in crossfire and 8 core processor
    i downloaded the latest amd app sdk v2.8 win 64 and installed
    i tried to update graphics driver but amd site says i have the latest installed, it is driver version
    ive pointed the miner to my pps acc at notroll, and enetered u/name pass and port
    i set stratum as off to make sure i connect ok as ive not used stratum at notroll before
    selected 1st graphic card and used auto settings
    when i click start, nothing appears to happen, ive waited but with no joy

    any help would be greatly appreciated

  27. Jamatrix Says:

    This is not a very good tutorial. I am a web developer and design and write software for a living and can hardly figure it out (from this tutorial). I would have to do multiple other web searches to get this going since you only mention AMD drivers and SDK. What about NVIDIA cards? If I want to spend a few hours getting this to work it would not be a problem, but your title says not just “beginners intro” but “Absolute Beginners Intro”, which it is not

  28. Air Jordan Says:

    Same story here, stuck at Starting… :(

  29. CryptoJunky Says:

    Kimbo – I had been putting a post on CPU mining litecoin but I’m not sure it’s worth it anymore given the rise in difficulty. Perhaps I’ll post it anyways for informational purposes if nothing else.

    aminer – Scryptminer is still very new and to my knowledge doesn’t support dual cards. If you’re using your rig for mining and not gamine/other activities you might try taking it out of crossfire (not positive that will fix it but it might). Otherwise I’d suggest giving CGMiner a shot as it has a lot more options. I’ll look for a thread on it and get back to you. It runs from the command line and supports both SHA-256 and Scrypt mining. Also, if you do go that route make sure to include -scrypt when starting it.

    Jamatrix – I’m sorry to hear that you’re having trouble with the tutorial. Nvidia cards are generally not as useful for mining and as such there is much less available in the way of support for them. Also, litecoin mining is notoriously finicky. I’ve purposely excluded less used configurations from the guide in order to keep it as short and simple as possible. If you’re brand new and having problems I’d suggest trying an easier coin such as Bitcoin or Terracoin. Most video cards have very few problems running GUIminer for these coins.

    As far as those that are stuck at ‘starting…’ I’m not sure what the problem is. I suggest looking through the bitcointalk thread on Guiminer Scrypt (as will I). Recheck your settings as well. If you still have problems post your card make/model and operating system and I’ll try and figure it out with you.

  30. Ben Says:

    I also had the “ImportError: DLL load failed: Can not find the specified module” error – but I found a solution:

    I only wanted to do CPU mining, as I do not have a GPU for it (the 2 systems I tried on only have integrated video cards, and not from AMD nor NVIDIA).

    I didn’t want to install the AMD APP SDK and AMD drivers – since I do not have an AMD card! -, but it turned out it was still necessary.

    As a last resort, I tried installing the “AMD APP SDK” and the AMD drivers (refered to as the “Known working for all cards AMD driver (12.8)”, on the GUIMiner-scrypt page: )
    and it did solve that error for me, GUIMiner-scrypt finally loads!

    I hope it can be useful for others.

  31. Jay Says:

    I noticed that on coinotron when you put a username and password into the new worker Fields the password is clearly visible when saved. It kinda disturbs me a little. The only issue I’m really having is actually getting the GUIMiner to start. I just copied all the info you had into the diff fields to see if that would work for me. I have a gaming laptop and I want to see if it will mine. Here are a few questions that I think need clarified.

    1) What should I put into each field in GUIMiner? Host, Port…etc
    2) Could you show an image of how to properly add a new worker on coinotron or at least an image with big arrows pointing to where to enter your info and what info you need to add?

    Thanks for the intro, do you recommend any other investments
    also can we receive bitcoin transactions in by using our litecoin address?

  36. michael Says:

    did exactly as the tutorial said, and guiminer says can’t make up its mind if there is connection issues or if it’ll stop connecting.

    @gamma You need to turn stratum off for litecoinpool

    For people having trouble with starting, sometimes cgminer hangs for a bit when trying to make the kernel (no clue why). Hit stop, then hit start again, and wait for about 4 minutes and see if it starts mining. Try also reaper miner.

  44. deanis91 Says:

    thanks for the great guide.

    I’m having a problem with the GUI Miner Scrypt.
    I had it up and running yesterday, but today it seems that every time i try and open it, it stays minimized, and refuses to maximize at all (win7).

    Any suggestions?

  45. gamma Says:

    @tacotime – many thanks! That fixed it! Odd – litecoin says it supports stratum, and I am mining on their stratum port. Without stratum. /shrug It’s working, but I’d love to understand _why_ it’s working.

  46. techbytes Says:

    @deanis91 – you probably have the options “Start minimized” enable. Just right click the bitcoin icon on your taskbar and select “Restore” then go to “Options” and uncheck “Start minimized”.

    Is there an easy way to slow down or de-prioritize the mining in order to reduce system slowdown & graphical glitches? Ideally I’d like to be able to mine at full speed when the system is idle but without affecting normal operations when I’m using the computer.

  51. CryptoJunky Says:

    @Jay, the username/password for your worker being visible shouldn’t be a problem since it doesn’t allow anyone to access your account. The worst they could do would be to set up a miner that mines for you. As for settings, the image above has the settings you would need, just choose your GPU model and it will fill the rest in.

    @M.n, It sounds like a settings problem, make sure you’re using your worker username and password, and not your coinotron account login.

    @John Smith, Set the intensity to a lower setting. I wouldn’t have it above twelve if you’re using your computer for other things. You’ll basically just have to change the intensity depending on whether or not you’re using your computer.

    @mason, Make sure you’re using your WORKER username and password, and not the username and password for you coinotron account.

    I was wrong about bitcoin. So I’m in on litecoin hoping for the best. I found your article searching with the phrase:

    “Mining litecoins at 0 hashes per second”

    It seems for casual computer users there is a learning curve to mine litecoins, which might be a good thing for a while.

    Your offer of some free litecoin encouraged me to post.


  56. Prince Says:

    I got everything up and running. Reaching a khash/s of around 380. Yet doesn’t seem to be changing at all? I dont see any bitcoins being mined and I’ve been running for about 4 hours.

    Is something wrong?

  57. purplefetus Says:

    I thought lite coin mining wasn’t geared toward GPU mining on purpose and it’s primarily a CPU oriented mining. Then why is CPU mining becoming obsolete? I also heard ASCI chip sets will not be useful for litecoin mining. What’s the deal, I’m confused…

  58. bob Says:

    So if you are one of the developers or friends or family of them then mining coins is great cause by the time everyone else figures out how to config a mining setup you are all rich and no one else will ever have a chance woot!
    Of course if you are already rich then you can afford a room full of computers chugging away all day at this as well. Cyber currencies appear to be just another pyramid scheme that benefits those in the know and leaves everyone else chasing their greed into eternity.
    How about a digital currency that is time based? That saves everyones computer from calculating all day clogging up the net with blocks and issues everyone an equal amount no matter what hardware they use. Just a suggestion…

  59. raf Says:

    excuse me, for cpu mining with core i7 2620? since i have notebook with nvidia 520 m maybe using the core i7 is better…. also if notebook mining is not good at full power please tell me how to maintain cpu level in good conditions…. thanks

  60. Prince Says:

    I have got everyting set up. Followed the guide. Mining at around 380khash/s but still my coinotron account is not updating at all.

    The khash/s field is idle at 0.0 and the Last Share(UTC) field is blank. I have been mining for 6 hours.

    What do?

  61. mason Says:

    Crypto@ yes I used worker, I’ve had no problem setting up and mining Bitcoin, I’ve followed every step of this article and ..starting.. is all that happens, I see by the messages there are several of us that all we get is …starting.. and no hash rate or mining ever starts

  62. purplefetus Says:

    Does anyone know approximately how many lite coins can you mine in a week using CPU mining? TIA!

  63. Danno Says:

    Can I mine with my nivida card? (a 550Ti)
    I notice you only post drivers for AMD cards.


  64. tacotime Says:


    If you select “View console” you’ll see that it outputs what cgminer outputs when you click start. For instance, if you entered the wrong username, it will tell you that there eventually. See if anything there gives you a clue as to what’s wrong and paste it here.

    I didn’t know which parameters put into the guiminer scrypt.
    I filled the fields randomly and I receive this message error:

    clDeviceNum returned error, noGPus usable

    I have an ATI Radeon Xpress 1100 on my laptop.

    Please help.

  71. tacotime Says:

    @Billy No, something is wrong eg wrong credentials used, something is wrong with the thread-concurrency value, intensity is too high, one of these things

    @James Both cgminer and reaper? Note that if you click View –> Show console it will dump the outputs of the miners and help you troubleshoot what’s going on with them

  72. John Says:

    Hey I noticed that the h/s on guiminer is inaccurate. When I compare the two hashing rates. The one on the guiminer is off roughly by about 50-100 h/s compared to the one on the pooling site (coinotron). Is anyone else having the problem? Make is quite difficult in adjusting my clock settings for the best ratio.

    Anyways I was just wondering if someone could send me like 0.1 LTC to confirm that i got my litecoin wallet working. any amount do suffice. Thanks


  73. Alex Says:

    Does anyone know the correct settings for an AMD Radeon 6670? It’s not available as one of the defaults.

  74. asdmaister Says:


    Donations would really help me out starting with cryptocoins :P

  75. dunnya Says:

    You need litecoin and coinotron installed with the same settings to start mining. Hope this helps as i’m a beginner also.

  76. nam812 Says:

    My Computer has an AMD Radeon HD 7570 1GB GDDR5 for Win 8, but I do not see that number listed in the GPU default drop down box on GUIMiner. Is there another number I can choose, or does my computer have the wrong card for someone wanting to mine litecoin?

    Thanks in advance for any help/suggestions.

    I have an i5 2500k overclocked with a gtx 560ti

    Can I use a nvidia card?

  78. Daniel_LTC Says:

    Thanks for the tutorial. I had it set up pretty quickly, BUT: although the GUIminer says I’m getting 169Kh/s, coinotron only says I only get 41KH/s (been running for about a day).

    What’s up with that?

  79. tacotime Says:

    Sorry, forgot to add 7750. Try thread-concurrency of 6400-8000 and see how that works.

  80. Aleister Says:

    Greatly appreciate the in-depth overview into the world of Litecoin!

    Although I’ll have to say that its killing me having to hold back on the mining, as it won’t be worth the risk to roast the guts of the MacBook over a mere few coins once the newly appointed graphics card comes through the post for my tower.

    In the meantime, here’s my address:

    Hey guys!

    SOLUTION to the “Starting” error.

    I had the same problem, and figured out the solution.

    First, make sure you have created a worker via the “ADD WORKER” fields at>Myaccount

    Now, copy EVERYTHING under the “name” heading. For example, do not just use your coinotron username–there will be more to it, for example, “usernamehere.Worker1″

    Hope this helps!

I do entrust the crypto algorithm.A crypto algorithm that is open source based on public keys is nearly impossible to break, an account on a bank is very simple someone need to know public information about you and you are done.

    Hi Chuck,To answer your queotisn im currently not making anything lol. I have been saving up my bitcoins to buy a Jalepeno, you can find more information about it in this post . The great thing about it is that you can buy it with bitcoins.After I bought the Jalapeno I had a few issues with my computer and internet connection and havent had chance to sort it so I figured I will wait till I recieve the jalapeno and sort it all out one weekened. I will take some photos and notes while setting it up and will post how I get on, put some sort of guide together for any else who is looking into the Jalapeno.While it was running though I was making one bitcoin every ten days, Im not sure what that works out at in USD but if you go to it has the current USD value accross the top of the page.Hope that answers your queotisn.

    Hi, I was drawn to litecoin as it is apparently cpu mining friendly, although I am saddened to see it leaning more toward gpu mining, I suppose this is to be expected, could you please provide details of where and how to mine litecoin usingcpu only configuration please? I have 2 systems, core i3-330 and amd phenom II x3, they have intel hd graphics and amd mobility radeon hd 4250 accordingly, neither gpu’s are supported but I would like to setup the miner utilising the cpu’s, primarily for the experience of mining, can you assist? many thanks, Peter

    Hi there, thanks for the article. I’ve been using Guiminer to mine bitcoins with my gpu for a while, and am thinking i should be able to use my cpus (2x Xeon X5355) to mine litecoin at the same time using guiminer scrypt.
    Trouble is, i can’t find any info on the correct settings for cpu mining, which is perhaps the reason why i get no further than “starting…” and no hash rate. If you have any idea where i can find this info, i would very much appreciate it, and will happily donate some ltc once i have started mining it :)

    First off, I appreciate the introduction into LTC Mining. As a noob it was very helpful to get started. I’ve been tweaking a few things to maximize my hash rate and have had great results with the GUIminer Script (V.02). However I am having some issues with stales. I’ve got a 30-40% stale rate on three separate machines/miners. I’ve tried multiple pools and have the same result regardless of the pool. I’m using the built in settings for selecting GPU settings (7950, 6850, 5770) The 7950 is Clocked 1150, Memory Clock 1570 MHZ – 610mhs steady at 37’C. The 7950 has 1412 shares accepted/ 507 stales. Horrible loss! The other two cards are just at standard clocking. The 5770 has 1060 Accepted/ 339 Stales. The 6850 has 1333 Accepted/ 366 Stales. Any help would be appreciated. THANKS!

    Then i got the hangs-at-“starting…”-issue. I simply forgot to use Port 3334 for instead of the default 3333. Solved

    Now its connecting … and thats it…..i will report if i find my solution,
    i hope i could at least help some others with the previous problems

    Ok, if anyone is running cgminer for LTC mining and you’re getting absolutely horrible performance or cgminer crashes, make sure to read this thread very closely, as it tells you about some environment changes to make to ensure that thread-concurrency works when set to higher values:

    I don’t use guiminer as I like to specify exact settings, and cgminer kept crashing, but with the instructions listed in that thread, I’m consistently getting >500mhash/s rates on each of my 7950s.

    When I try to start guiminer-scrypt, after 15-20 second thinking it drops an error window:
    “The specified module could not be found. LoadLibrary(pythondll) failed”
    Then an other window pops up: “C:\Users\username\AppData\Local\Temp\PYTHON27.DLL”

    I have an i7 cpu with nvidia 560m gtx, and I already installed the latest nvidia drivers + cuda 5.5
    With guiminer I can mine bitcoin without a problem, but this just won’t start.
    Someone above said that the AMD drivers and SDK should be installed even without having such a video card to be able to run guiminer-scrypt. But how? AMD drivers won’t install when it can’t detect an AMD card in my system… So I’m kinda stuck here.

    Any suggestions? Thanks!

  128. szcsongor Says:

    Now I can run the cudaminer separately from a cmd line, guiminer-scrypt probably needs an AMD card to run.

    It would have been nice to mention this in the guide that it won’t work with nvidia…

  129. CryptoJunky Says:


    Nvidia cards are generally not as good at cryptocurrency mining as AMD/Radeon cards. This is probably partly due to how the mining programs are coded. I’ve seen guides for running Nvidia cards out there, but they are generally considered to not be worth it when it comes to mining. Top of the line Nvidia cards mine at a fraction of the efficiency of middle of the road AMD cards.

    So I get the hang on start up the bitcoin miner seemed to configure itself it is a windows 8 app so I know stuff will run. Someone had said the reaper setup might work but it didn’t here is the error doesn’t say much.

    2013-11-17 22:07:52: Listener for “ReaperLTC”: Error 52 getting work. See for error code explanations.

    I used port 3334, I put in all the “default” settings, I have a worker setup on dont know why I dont get a response back. any ideas?

    Any Ideas?

  133. CryptoJunky Says:


    I would assume that has something to do with not having your pool setup correctly. Double check your settings there and see if that is the issue.

    Many thanks for your tutorial. I am NOT tech savvy. Ergo, when I attempted to generate bitcoins on my PC, my wallet never showed anything. Thanks to your “Litecoin for dummies”, I’ve successfully installed the requisite software and it is working. One note: Coinotron is currently not allowing downloads due to server issues. I decided to set up a sole account instead.

  152. Steve Says:

    I’m working with 4x powercolor 7970’s on a gygabyte MOBO. All four GPU’s and the CPU show up in the device drop-down in the guiminer. But I only seem to be actively mining with 1 card at about 600+ hs.
    Any suggestions on how to fix the issue?

  153. CryptoJunky Says:


    If you’re using GUIminer Scrypt you’ll need to open up a new instance of the program for each GPU you want to mine with. With some of the command line programs such as cgminer or reaper this isn’t true and you can run all your GPUs from one program instance, but with GUIminer Scrypt you need multiple program instances.

    Somehow every single forum and instruction manual misses that key point.

  167. CryptoJunky Says:


    Basically you want a dekstop computer with one or more high end graphics cards, preferably cards made my Radeon. Some top cards are Radeon 7950, 7970, R9 280x, R9 290x. This guide covers using windows and a radeon card, though you can mine with linux too as well as Nvidia cards, though Nvidia cards aren’t as efficient.

    What I have been searching and not able to establish is if arrangements such as attaching a high end Graphics card like 7970 using eGPU to my laptop externally will work or not . My Thinkpad contains an express card slot for connecting eGPU.

    Since the above arrangements involves a good cost to me , I am looking at the feasibility of doing investment to buy eGPU and Graphics card

    I down loaded “” but the my antivirus software “Bitdefender” found a threat called: “Gen:Variant.Application.Graftor.74420” in the file: “cgminer\cgminer-fpgaonly.exe”

    Is this a real threat or a false positive?

  179. CryptoJunky Says:

    Well you shouldn’t need that particular file anyways, it is a version used just for mininig with FPGAs, which few do. Your antivirus software likely flagged it because it is mining software. There are been many cases where mining software was included in malware in order to turn random computers into mining slaves.


  180. Patfromkansas Says:

    Dear CryptoJunky,
    I’ve been following the threads…I have successfully installed GUIminer. I’m running and AMD Extreme 3 MOBO with 4 AMD 7950 GPUs. I’ve installed and verified all the latest drivers. Same problem as one guy up higher had (Steve)- I’m only clocking 564 khash…feels like only one card is getting warm…was I supposed to place the ‘jumper’ cables between the cards? does it matter what order of power cord I placed on them? I ran one into the MOBO (top slot) and other 3 with powered risers. OR….is it a matter of opening/installing another ‘instance’ of CPU minor…how do I do this? thank you very much! Pat (previous post was = If you’re using GUIminer Scrypt you’ll need to open up a new instance of the program for each GPU you want to mine with. With some of the command line programs such as cgminer or reaper this isn’t true and you can run all your GPUs from one program instance, but with GUIminer Scrypt you need multiple program instances.)

  181. CryptoJunky Says:

    Pat (from Kansas),

    At this point you can run multiple GPUs with one instance of GUIMinerScrypt, but you need to create a new miner tab for each GPU. If you’re mining with Radeon cards go to File->New Miner->New CG Miner, then give it a name such as GPU1. Enter the pool details and settings for your specific GPU and hit start. Do this for each of your GPUs.
