Upgraded driver to 280.26 - I note my PPS(S) CUDA WUs are completing ~12% faster.
Usually took ~68-75mins, it's down to ~57-64min now. So every 10 WUs, +1.
Stable - 8800gtx.
Anyone else seeing speedup? Or something is messing (good) with my cruncher.
Thought I'd try this with one of my GTX460 cards which was running v258.96 at a consistent 19:37 for the current WUs. Installed 280.26 and the the WU completion time increased to a consistent 21:09. Thanks to Driver Sweeper got v258.96 installed again and the times were back to 19:37. I've tried a couple of the builds between these from time to time on different boxes and they were always slower than v258.96.
Instead of 20min 20sec I get around 19 minutes using the older driver on one of my GTX460's so I'll install it on the other one too.

Fluctuating times for completing PPS Sieve WU's

And again this morning I found it "crunching" at 810MHz ?????
Reinstalling 260.99 didn't do the trick.
Will try the older ones later today.
Using a K9A2GM-FD / FIH/2GB but don't find a setting that could change it.
Before I had a slow 9500GT on it and don't know anything about slowing down with that one.
GPU-Z gives the high clocks while it is running at half of it's speed
Read something about switching off Physx for gaming but what for crunching ?
