Super excited to get some cards that can overclock as my old 6870's are crap at overclocking. I'm hoping to squeeze 1300+ on each of them, is that too much to hope for on an sli setup? What real world temps should i be expecting for an sli of these bad boys? Have a Haf X and an h100, so the airflow should be pretty nice. Again, super excited for the cards and to join the owners club!
1300mhz in SLI is entirely probable, yeah. As you can see from mine, you'll have to test the cards and put the better one on top, as there's probably going to be one that does a good amount better than the other. Comes in handy when I only want to use one card for a particular game
But yeah temps in SLI aren't bad at all, especially if you have decent fans in your HAF-X, particularly the side-panel one that blows right on the cards. I've ran +93mv in SLI before, and I think I have my fan curve to hit 100% around 64C, just to keep them nice and cool since I usually have headphones on anyways. I've literally never
seen either one of my cards hit 70C. Whether in SLI or 3dMark11 runs at 1460mhz/7300mhz (granted 3dMark11 is short, but thats still a lot of mhz/volts), never been in the 70C's before.

Not every card is the same , some need more "juice", that cannot be helped .
Try to put +18mV offset and +60MHz offset and see ...
Is anyone running LN2 BIOS 24/7?
I have since the day I got them. I use stock clocks most of the time since these in SLI is more than enough at stock speeds. But the top card is the better one so I usually undervolt it to -50mv core voltage before gaming instead of opening the side panel and switching BIOSs everytime I want a good overclock. It's been stable in every game at the stock 1202mhz at -50mv, so I'm going to start testing the next increment soon.Edited by dph314 - 9/10/12 at 12:55pm
