I expect driver crashes from 6.07 stock but not from V5b build - it should autokill itself before GPU will be even touched.

Yet Raistmer's 9600GSO was too slow. I was hoping a few ective users could post comparisons (maybe just the floats, not the whole graphic), and whether they can get work from Beta, so we could work out where the cutoff came. People are already asking questions on the SETI Main board.

It was shown in David's message, clockRate * multiProcessorCount * 2,857 is how the Scheduler will estimate GPU speed. The clockRate and multiProcessorCount are reported by the host.

Raistmer:
Ok, 12*1700*2.85=58140 <60 000 Thanks, Joe :)
ADDON:
I hope this ridiculous measure will not lasts too long :) (even brand new gts280 or alike experience driver restart on VLAR.... )

Ah, so my 9600 GSO running stock , is 1350*12*2857 = 46,283,400 , No problems, can crank up the clock later if this thing proves stable at stock.

@slawek, your gfx-driver-version?
and what app-version are you using !? (Triplet count: 31 found at your results ...)
