I heard that most of the 7950 can achieve that overclock with stock voltages.
edit : I dont want to increase voltage because it is a reference card.
No, mine card wont do 1 GHz on stock volts too, it wont do even 975 MHz on stock volts, its low voltage card, stock voltage is 0.993V.
But with more volts, it can do 1100 MHz without a hitch.

Guys i have question, i am in big dilemma about buying second HD 7950.
I somehow decided to my second HD 7950 be MSI TFIII, big question to the experts and all of you is that can HAFX hold MSI TFIII and Asus DCII (one slot spacing between cards) under 70C with custom fan profile, overclocked and overvolted?
Thx everyone in advance.

I would think this would depend on your cooling factors. Like fan speed, ambient temp and where the case is. Individually they can do that, but together the one of them would run hotter.

Now ambient is pretty high, but i can bring that down with AC, also i think DCII should not have any problems, because its going in lower slot, i am more worried about MSI because it will only have one slot to breath, because when OC, when they hit 73C i see artefacts, at least with DCII. Majin also reported same with his all 7970s cards.

Liquid TIM, some guys used it on Ivy Bridges dies, after popping up IHS. You need to be very, very careful with that paste, some people who did not apply paste properly on IB dies, experienced sudden temps spikes, up to 20C. But if you apply properly its very good, i am also considering to order one.

How do you remove it and how much would be too much?

2.2.2 does not include the necessary. DLL to work with 7970s properly. 2.2.1 does.
