Hi all,

I'm a total newbie (I'd love to post this in a more relevant forum if I could... cough cough hint hint), and I had a question with regard to my GUIMiner settings.

I'm rocking a Nvidia GTX 460 1GB in my desktop, and, being new to the scene, I blindly trusted the -gputhreads=320 -gpugrid=336 flags posted on the mining hardware comparison page for my card. How am I to know if these are the best settings for my card and computer? Is there a discussion/wiki/infodoc on rpcminer's cuda executable? Can anyone give me any guidance on this?

Thanks,
John

Hi i'm using -gpugrid=256 -gputhreads=512 -aggression=7 on GT420M. You have to set different settings and check the mining speed. It should be stable, that means if You are getting:
200 Mhash/s
800 Mash/s
200 Mhash/s
Then You should lower Your setting to get for e.g stable 700 Mhash/s.
My methodology was to set -gputhreads up to 512 because it was stable value for me, then set -gpugrid up to 256 because it was also max stable value for me. And last thing was the aggression set to up to 7. Those values are giving me maximum stable Mhash/s.

Also try my modified CUDA miner:
