Hi Guys and Gals,
So I've decided to jump on this whole mining thing but I'm not sure I'm getting the performance I should be, can anyone suggest any changes to the below setup to see if we can make this go any better?
I have 3 nVidia cards in the desktop I'm mining on, 2 X GTX590s & 1 GT 640, after an autotune I've ended up with the below settings:
(590) GPU0
-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14
= ~102kh/s
(640) GPU1
-H 2 -i 0 -d 1 -C 1 -m 1 -l K56x8
= ~43kh/s
(590) GPU2
-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14
= ~43kh/s
(590) GPU3 Main Display attached, not mining, even with -i 1 framerate drops to ~5fps and system is unusable.
(590) GPU4
-H 2 -i 0 -d 0 -C 1 -m 1 -l F16x14
= ~75kh/s
As you can see the performance of the 590s is all over the place, SLI is definitely disabled and I would have expected them to have similar performance or is there something I'm missing?
Also is there an easier way than trial and error to identify which device is which as far as cudaminer is concerned?
Thanks in advance for any suggestions!
Bill
