Gtx 570-unstable OC? - Page 3

post #21 of 28
Yep, increasing the memory clock will only increase performance noticeably at higher resolutions. Just aim for a high core overclock with stock memory clock and you will see a difference.

We have the same Asus 570. These things are beasts and can safely take the extra voltage without a problem. You shouldn't really mess with memory overclocking, though. It's pretty sensitive and can cause permanent damage if you take it too high. Besides, it barely increases performance. I only set mine to 100mhz over stock settings.

I dunno about that. While playing BF3 @ 860/2000 there was like a 10 fps increase compared to stock settings.

Reread my post. I said overclocking memory barely increases performance.

That frame rate increase you experienced was mostly from the core and shader overclock, not the memory overclock.

Hey, your sig rig says you have two Asus in SLI, hows that working out? I thinking about doing it too depending how my rig manages with bf3. I have a mid atx case so I'm kind of worried about space. Hows the temps in your rig? Also, you think a corsair ax 1250 is enough power for them even if their OC'd?

Actually, only one of my 570s is the Asus DirectCUII. The other is a reference Zotac. I did not want to sandwich these two cards together as they would be starved for air and temps would sky rocket. I also needed space in between for my soundcard. Right now, the reference card is in the top PCI-E slot, and the Asus is in the second one. Asus provides ample space on the motherboard. The setup works perfectly. The Asus still stays super cool at around ~50C max temp, and the top reference only gets to about 69C max.

Also, a Corsair 1250w is way overkill for these cards. My Seasonic 760w handles the setup perfectly, even when i overclock them to the max. A Corsair 1250w can support two GTX 590s in Quad SLI.

K thanks alot, Im looking at maybe getting an MSI twin frozer III, since its only a dual slot which would help with the space restrictions. I get uncomfortable with temps above mid 60's . yea I had a feeling it was overkill but it wasn't a significant price difference and better than having to replace it down the road.

one last thing, sorry, but is overclocking in SLI the same as overclocking a single, im assuming no. and do you think I should buy some aftermarket fans to help with the cooling or will they make very little difference (the really high rpm ones).
