Title: How can I get working 2 different nvidia cards with CUDA mining? Post by: Qu4k3r on July 27, 2011, 04:50:36 AM Hi,
So far, I was using guiminer (opencl) with 2 vcards on same pc gtx570 ... 117 MH/s ... @default clocks gtx460 ... 47 MH/s ... @default clocks Forceware 266.58 works fine; but with versions 270.61 & 275.33, display driver suddenly shows black screen and stops working. Now I want to use guiminer (cuda), but it does not show devices (gtx570 and gtx460) to select as opencl does it. Gpu-z shows cuda's checkbox enable on main vcard (gtx570) only, then I dummy plugged second vcard (gtx460) and got both vcards with cuda's checkbox enable. :) But still does not show any device to select. If I start to mine with cuda, it works with the main card only. I tried with some flags (-device=0 -device=1 device=0 device=1) but not succeed. How can I get working both cards? Any idea or suggestion? Thanks in advance ;) btw, cuda mining improve the hash rate by 23%!!! gtx570 ... 144MH/s @default clocks with flags: -aggression=5 -gpugrid=480 -gputhreads=960 Title: Re: How can I get working 2 different nvidia cards with CUDA mining?

Anyways Nvidia not as good for mining. Title: Re: How can I get working 2 different nvidia cards with CUDA mining? Post by: Qu4k3r on July 27, 2011, 06:23:31 AM Problem was solved by adding this flag (-gpu=1) to the second vcard miner.
I know nVidia is not good for mining but... I got a lucky shot becuase I solved a block mining in SOLO mode with the 570 in less than 10 min, LOL.- BTW, You can not SLI different cards.- Title: Re: How can I get working 2 different nvidia cards with CUDA mining?
