Topic: How can I get working 2 different nvidia cards with CUDA mining? (Read 2289 times)
Good thing you solved it.
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.-

Maybe by SLI?
Anyways Nvidia not as good for mining.

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
