You can grab current and past CUDAminer versions from this Bitcoin forum page. You can use Nvidia cards with CGminer, but you'll be missing out on a lot of speed. Asteroid in OS XĬUDAminer is to GeForce cards what CGminer is to AMD cards-Nvidia supports OpenCL, but it is (unsurprisingly) more interested in tuning its hardware and drivers to work with its own proprietary GPU computing language. Depending on the age and speed of your card, you may be able to get anywhere from a couple hundred kH/s to over a thousand, demonstrating why AMD cards are so popular with people who mine with their GPUs. Your best bet would be to find your GPU (or the most similar one you can find) on this Litecoin wiki list and add those arguments to the CGminer command. You can make changes to CGminer's settings as it's running, but doing so blindly is a good way to break things. This will start cgminer with the default settings, but these will rarely be the most efficient settings. cd desktop\cgminerĬgminer.exe -scrypt -url=stratum tcp://:3333 -userpass=.: Basic usage is almost identical to CPUminer-open a Command Prompt window to continue. Like CPUminer, this is a command line tool, and we'll be extracting the CGminer.exe executable and all related files to a desktop folder labeled CGminer for the purposes of this tutorial. This blog appears to host a clean and working Windows binary, or you can grab the official source code and compile it yourself if you're feeling adventurous. Current Catalyst versions include AMD's OpenCL driver, but you could install AMD's APP SDK for good measure if you're not getting good results.ĬGminer 3.7.2 was the last version of the tool to support GPU mining, and it has become a little difficult to track down. Some versions are thought to be "better" at mining than others, but for our purposes it's probably safe to start with what's newest and work backward later if you discover your card works better with older software. If you're in Windows, the first thing to do is make sure that your AMD GPU has the most up-to-date Catalyst drivers available.
