Then will go on and purchase a better CPU. Any CPU in particular you recommend?

I've got a dual-core Athlon in a similar 990 board, and my 750 Ti still produce slightly less hashrate than the same cards in z87 rigs with dual-core Pentium G3xxx, so you want at least a dual-core Athlon working @ ~3 GHz. If you'll find a cheap Phenom x2 (a lot of them have the 3rd or/and 4th core stable, so they can be unlocked and become a triple-/quad-core), or Athlon x3/x4, that would be even better. I suppose what matters here is that you need to have at least 2 cores and you need something around 3+ GHz (for AMD cpus). Not sure about the cache requirements, so better be safe I guess and look for Phenoms first.

Yea, or just go for it and pickup a couple of 12 core XEONs and be done with it. Grin

Yeah eventually I could use it for something else afterwards. BTW using the -d flag to run only one card gave me the same hash. No changes there. You still think this is a CPU pb?

I am also getting this once in a while. See video: nvminer goes crazy

OC the card and increase the TDP 38.5w limitation to avoid miner going crazy once in a while.

Thanks for the recommendation. However, I do not want to OC the card. It usually introduces new problems which for now I want to avoid.

I mentioned this a couple pages back but didn't see a reply, I think the issue you are running into is because you are comparing hashrates from overclocked (stock or by the user) to your 'vanilla' 750Ti's. I have 3x EVGA 750Ti's and the rates I get from them non-OC'd are exactly what you are getting right now. However, raising the TDP and overclocking them to +142 core/+528 mem gets me the hashrates (sometimes a bit better) than what is generally quoted. Stock OC'd cards are in the range of +100 core out of the box so that explains why some people with "stock cards" are getting better rates than you are.

If anyone is running a stock 750Ti with reference clocks and getting ~2.7MHs on X11 I'd love to see it
