Uh-oh, I think the benchmark WU now has a problem! Seems you were right afterall Sunny! Don't know why you got hit so early though
This has only occurred today, but I now see that my 213.76 WUs with the GPU at 825 MHz completes in either 216s (as before) or 144s!
I was wondering if the overclock was suddenly unstable, however that's looking very unlikely as all the 'quick' 213.76's are being done in 144s +/- 0.1s. Just incase I'm testing now at 800 MHz.
Strangely most of the quick validated 213.76's I've crunched have apparently only been crunched by me! Bar 2 of them, the 1 user I checked (who also has a 5800 card) also has a similar variance, long ones taking ~248s & short ones ~168s (see
here, TRAILBLAZER). By those times I reckon he's got a 5850 too.
So it now seems their can be 2 times for the 213.76 WUs!
Well seeing as their are only 2 different speed WUs it is still useable as a benchmark, so far! But if they add more different speed 213.76s WUs then it will scupper the benchmark.
For now, I'll say pick the 'long' 213.76 WU times & average 5 of them.
[update] Looking at another cruncher whose validated 1 of 'my' WUs further confirms the variance,
DokV, he's got a 7900 series based card & is either getting ~50 or 77s on 213.76 WUs.
Sunny
I'll take the longer of your times
.
[update2] Looking at 4-5 users the difference between the short & long WUs is ~50% +/- 5%, so the long ones take approx. 50% longer than the short 213.76's.
[update3] 5850 @800 MHz, 213.76 WUs ~223s & ~149s. So definitely not an overclocking issue.
