I've recently moved over from Nvidia after my 750 Ti basically blew up on me, so I have an R9 280x now.
I'm trying to get to grips with the original cgminer, but then I'm also finding more and more forks of the original miner which are basically used to improve hashing rates. Which is fine, I have no problems with that, but I'm becoming confused on which miner I should actually use.
So could anybody give me a hand?
Right now I'm mining x11 at 3.3Mh/s using a .bat file config, which is below.
setx GPU_MAX_ALLOC_PERCENT 100
sgminer.exe -k x11mod -o stratum+tcp://useast.blackcoinpool.com:3333 -u Lizzardis.1 -p
Right now I'm using this mod which is linked in the OP of this thread, and I'm getting those results above.
Can anyone give me any idea of which SG or CGMiner I can use in order to squeeze out more hashes? And also how I can tweak my configurations to do the same?
I'd appreciate any help at all!
Thread concurrency is not used with X11. I have 290X's, so my advice may be a little off, but try playing with Xintensities around 64 or 68 (for some reason even numbers consistently work better for me). Also reduce worksize to 64. You can also try bumping up your clockrates modestly until you start seeing GPU's go sick/dead. I'm using SGminer 5 builds that I think came from badman (backtrack in this thread and see his link in his signature). I'm thinking you should be able to get to around 4.8 MH once optimized (I get just over 6.0 with a 290X and I think a 280X is about 80% as fast), faster if someone shares some of the new kernels that people are boasting about here....
My best advise is to backtrack in this thread and take note of the configs people report success with. Try the various hamsci settings and so forth one at a time keeping track of the results each time.
