two 570's, getting different PPD at same clocks, why? - Page 2

post #11 of 24
Did you move that one to the same slot? If yes then I would try new drivers, last resort would be flashing the bios.

yup, same slot

is the 19k ppd card special or normal? i dont get how there can be such a huge difference in clocks

the 19k card has the OLDER bios too so what do i do? flash the new one w/ an older bios?


wow, this makes no sense

Backup both bioses, and try putting the older one on the other card, it could be that. Some BIOSes will be better suited to fold, but may have problems/bugs/slower speed when gaming. Usually GPU makers go for the gamer crowd, and forget about the folders (you're a smaller market by a long way).

Newer doesn't always mean better.
Personally I would flash it to the old one and give it a try, after testing different drivers of course.

Another thought... it could be down to something as basic as different tim on the heatsinks.. A less efficient TIM would keep more heat in the chip, and lead to it hitting max temps at a lower clock speed. Or heatsink mounting could be off... Could be anything.

I have the same problem. Both my 570s are clocked at 1788 shader, both flashed with the updated bios that allows 30-100% fan profile, and both don't care which slot they are in. The first one I got was the SC version, that one is giving me 15.8k. The second one is the regular version, that one is giving me 18.5k. It doesn't matter which card is on top, it's always 6degrees celcius hotter. Same difference if I fold on the CPU or not. Drivers are 263.09. Fun times.

Not sure if it's been asked, but do you have SLI disabled? If you don't, try turning it off. Don't know if that would make a difference but it could be worth trying.

thats really weird... have you tried each card by itself yet?

i might go exchange this one for another one... and see how it is

what if some 570s just fold better than others? is that possible?

because by now ive had each in my rig separately/alone and one gets 19k and the other still gets 16k, same clocks/drivers, doubt bios would make a ~3k difference
