My previous article on Litecoin mining I discussed how you can get started mining Litecoins , an alternative to the Bitcoin crypto-currency, using your spare CPU cycles. Whether that trade-off is worth-while is a decision you would need to make. Litecoin is not as mature as Bitcoin and is just as volatile. Some see it as a doomed clone, others as the next Bitcoin, poised to take off.
Please read my previous article on Bitcoin mining for step-by-step instructions and installation packages for cgminer and bfgminer. The Homebrew formulas I shared in my previous article include the configuration settings necessary to mine both Bitcoins and Litecoins. If you are compiling the applications yourself, make sure to use the —enable-scrypt parameter when running.
Armed with a copy of cgminer or bfgminer with scrypt enabled, you can now start mining Litecoins with your GPU. Now a fair warning: With Bitcoins you can basically run either miner and just specify your pool.
The miner will then tune itself and eventually reach a nice hash-rate. Note that I am using the -d parameter to specify which GPU to use to simplify these examples. Using bfgminer with the basic command-line parameters yields similar results.
So how can we get better performance mining Litecoins on the GPU? The first parameter to focus on is the -I parameter, or the intensity. With Bitcoin this parameter does help, but honestly not a ton. This is not the case with Litecoin mining.
On my system, is about the best I can do. The next parameter to focus on is the -w parameter, which specifies a worksize in multiples of 64 up to This parameter is what really makes a difference on my OS X rig:. The last parameter I want to note is —thread-concurrency. If cgminer or bfgminer are reporting hardware errors the HW number in the output this indicates that you need to make use of the —thread-concurrency parameter.
These are not hardware failures. You can find guidelines for the value to use here:. Ideal values are or Find your bus width here. The growing landscape of crypto-currency is fascinating from many perspectives. If your interest is piqued and you are running OS X, hopefully you now have the information you need in order to get started mining this new form of currency.
Starting with version 3. Additionally, bfgminer now requires an additional argument in order to enable GPU mining. If you wish to use bfgminer for GPU mining you will need to add the following argument:.
Thanks for the excellent guides on starting mining on a Mac. I have been trying it out over the weekend on a couple of different laptops, one Air and one Pro. Obviously, neither of them are heavy hitters but the experimentation is quite fun. I found MacMiner to be better than doing homebrew installs, surprisingly. It gives a cryptic OpenCL initialization error: Enqueueing kernel onto command queue.
Finally was able to get Cgminer to compile and install correctly for Lion.. Try a worksize of 64 instead of Also, try removing the lookup-gap. If things are stable then start upping the intensity. Thanks for the reply! If i take the intensity past 12 the computer freezes up: I read to add these lines in the terminal before the scrypt: Hey, I need some help.
Thanks for the article. Where does one get a username and password for the Terminal commands please? Can I use this setup for Feathercoin? How do I indicate it to mine feathercoin and not litecoin. It should work as long as your arguments are valid for Scrypt mining. Litecoin and Feathercoin should work the same. What sort of problems are you having? I have one problem proceeding with cgminer 3.
This had me stumped for a couple of hours today. As can be seen here: When you try to install it you will get a SHA-hash error. This worked for me. This has been a very helpful forum and I feel like I was so close. Can you help me? Sorry for the double post but I have tried everything. What can I do on my computer to speed it up? Is it the mac versions of the that is slow? Thank you for your help. I use -g 1 —thread-concurrency for my , but that is on Windows.
Note that scrypt mining is notoriously difficult to tune and much more so on a Mac. I have never been able to get the same scrypt numbers on a Mac as I can in Windows. Is it the stock power supply? Getting an Error whenever I try and use bfgminer.
Any thoughts on what could be going wrong? Any opinions on Asteroid? Am I sacrificing anything by using that app instead of a command line process? I seem to be having problems with scrypt that I hope you can lend your expertise to. If I run cgminer without scrypt enabled it seems to hash along happily if slowly with the following command line: If I try to run it scrypt enabled, using this command line: Building Program clBuildProgram [ Your email address will not be published.
