A few things going on at once now, first the gtx465's. I echo Micro's thought, both mine get 15500 on the 'medium' ones, and 16700 on the 'fast' ones. Probably just shader speed diff, mine are 1215 stock upped to 1518. This is trivia compared to the missing wu's of the last couple days though.
I think after VG looks at the link I posted last evening he'd say that only 353-ptrs. are making it out, so is that gpu's from both machines? Where's the cpu output, or is the other machine perhaps on a long wu? I initially was speculating here that with all the new machine o/c'ing etc, perhaps the machine was trashing cpu wu's and negating the Quick Return Bonus by taking overall smp completion ratio below 80% and killing the bonus, but it actually appears nothing's getting out from the cpu of any machine (last two days that is, all we can see)
Would you agree, VG, and does this point you to anything?
