That's where my first guess goes as well. If tests were not already run on a 680 and returned valid, knreed said they have from above, it really wouldn't have surprised me whatsoever. Don't know if code has been tweaked since previous betas, but the 680 definately did not like it. Besides the absence of FP64 (only 8 cores), the only HUGE difference that I know of, is that the scheduler is software based instead of hardware based if I'm not mistaken.

Oh well, when designing something new, invalids can lead to solutions.

The scheduler just sent me 3 more that all failed as before.

My 680 grabbed another 4, I figured I would let them run. I cannot post results currently as stats are updating. One thing I can say, is that I watched that gpu was running at default (1110MHz) speeds for sure this time.

The task stated .858 of CPU to be used, and while they were running, all other tasks suspended, the CPU used exactly 100% consistenly spread out on a number of cores or 100% on one throughout the entire task. With absolutely nothing running in background. According to system monitor only this task was taking CPU time (25), so the task was indeed using 100% and not .858.

I use W7 64-bit on this rig, with the desktop background at Windows Basic to take additional load off of the GPU. As stated before, I do have Einstein running normally, and these tasks were of course suspended across the board while these Beta WU ran. Don't know if that matters, but I figured I would include the info.

GPU usage, as indicated by EVGA Precision was at 97-99 while entire task was running, except for the end while WU was finishing (1 sec. mark I believe). The computer itself became very unresponsive during GPU use, meaning mouse would take long to drag, as well as other on screen visuals, such as moving screen around page. I expect some lagging, but since I run GPU apps on other projects, I personally thought this was a little much. Figured I would include said information. Once the stats have finished updating, I will report back results, even though I am expecting invalids, just like before.

165 + tasks completed without errors on 5 PCs / 6 GPUs all OCd to max
When I saw the release I freed a CPU core on all the PCs.

1) i7 Win7 x64 2 x GTX570 = 170sec
2) Core2 Quad WinXP32 1 x HD6750 = 400sec
3) Core2 Duo WinXP32 1 x HD5850 = 188sec
4) Core2 Duo WinXP32 1 x GTX560ti = 244sec
5) Core2 Duo WinXP32 1 x GTX550ti = 422sec

My main concern is the 40% GPU time wasted when the GPU is idle on both Nvidia & ATI

Edit: There is a BIG improvement on the PC's mouse response since the last batch

Same here - 100% cpu full time on ATI & Nvidia
Just the GPU drop to zero 40% of the time
