So now that we seem to have some pretty stable WUs working on the GK110s, I'm curious as to how they're performing against other cards. For those of you that have ran them, let's do some comparisons.

Post the following:

OS
Driver
GPU
Clock
Completion time

So, for me:

W7
326.80
780
1100MHz
4200s

That's a larger difference than I was expecting.

Thx for posting.

The actual clock speed of the GTX660Ti while running is typically 1189 or 1202MHz, not 1110MHz. The GTX660 is 1058MHz.

Don't know how close these WU's are to the real thing, but I suspect the GK110 cards might offer more to some WU types than others, and might open up opportunities.

Might also be of interest,

I2R14-NATHAN_s1p_test_titans2-6-50-RND4316_0 running on a GTX660 (W7)
GPU power ~97% (short run wu was 93%)
GPU temp 67°C (short run WU was 70°C) fan set to 67% (2100rpm)
GPU usage 95% (short run WU was 88%)
Core clock 1071MHz (same as with the short run WU)
Memory usage 879MB (short run was 403MB)

I had these on my GTX660. But I can´t give you the details when running as I didn´t see it at the time.

The one I have now I1R12-NATHAN_s1p_test_titans2-16-50-RND2792 running on the 660, uses:
GPU power: ~97%
GPU temp.:69°C
GPU load: ~94%
MEM load: 51%, 1048MB
Core clock: 1032MHz

TJ, in science there is nothing better than independent confirmation. Thanks,

Your welcome skgiven, it was a relief to me that my 660 is behaving almost the same as yours.
