Are the 6970's actually worse at OC'ing that the 570's?

post #1 of 7
Thread Starter 
I keep seeing in the various forums people say that the 6970's are worse overclockers as well as have much poorer OC scaling than the gtx 570's. Haven't tried OC'ing either, but curious what people's thoughts are on the validity of these claims. I always thought the GTX 570 was the weaker OC'er due to the vrm issue, unless you spend the extra $50-60 on one of the boards with the extra phases.

this is correct but the 570's are still slower. The 6970's already have such low tolerance binning that there's not much room left over.

the VRM issue on the GTX570s was a certain batch of reference PCBs from what I understand. And what do you expect from cards with the TwinFrozerII/ III or CurectCUII coolers?? They OC really well. On both sides AMD and Nvidia. I think just thereference 6970s dont OC so well cause they get hot and LOUD!

lol. Don't forget if someone posts any question about a GPU, if their cpu says AMD, it's garaunteed to get posts saying "well, your cpu is gonna bottleneck it"

i'm guessing my gtx570 vs 6970 thread must be one of those threads?
i'd also like to know about the OC power of these 2 cards...

Yup. I sent my MSI 6970 back after getting the silent revision version (post #13: http://www.overclockers.com/forums/s...d.php?t=674254 ) so I'm back to the drawing board. Looking at: 6970 (reference), gtx 570, gtx 480 ... all would be watercooled.
