No Issues so far. It would crash at 1100, backed it down to1050 and its stable. For about a week now.

I have the core version. I was curious. So you are running 1050 without any issues?

 

I am doing the same, blocks should be here today or Monday, reference coolers are to loud.

 

Have the bridge already.

Hi all. Need some advice. 

I'm running a Sapphire 7970 with RC 12.2/.3  drivers and have it oc'ed with ccc's overdrive 1125/1575 with stock voltage and with an asic at 68%

See several posts saying got this setup with 60/70/75 C temps and realizing I'm certainly running hot, but whether I OC or not I hit the same temps with fumark, which is 85 at auto 50% fan. With the prior version of the drivers it levels off at 81, but was always at stock clock. So seems oc'ing my card only affects the fps. 

So my questions are, are the temps I need to worry about in furmark or just in game (games currently are Witcher2/SWTOR/Skyrim)?
If both, where is best to adjust different fan profiles without hardsettting it to say 65% constantly?

Any other advice is also appreciated. My first OC on a GPG, so learning as I go along.

Everything runs just great, just not seeing the same temps. Figured did not want to go above 1125 anyway, but surprised to see my temps well above everyone else, if with everything at stock.

Thanks much.

@Overclocker55 Just do a clean install mate, it won't take that long and it's likely to fix all your problems.

@ped5, Furmark will stress your card much more than any game, and produce higher temps. For stability testing, I'd use Heaven and 3DMark11.

Pretty sure they just need the same GPU (someone else said vram amount as well) but the bigger problem you're going to have doing that I would THINK is that they'll run at different clocks unless you have the ref running hot. That or they're at different clocks and one works harder, right?

In a crossfire/SLI system, it will default to using the lowest amount of vRAM and the lowest clocks.
