Test Setup and Overclocking

AMD HD6990 Review

Test Setup

AMD Radeon HD6990
Intel Core i7-950 @ 4GHz
ASUS Rampage III Extreme
Muskin Joule 1200w
6GB Mushkin Redline
Noctua NH-D14
Windows 7 Ultimate x64


We've got two overclocking results for you today. The first is the current overclock maximum which gains the HD6990 another 45MHz. You can run this all day if you desired. The Memory overclock is particularly impressive given the normally poor GDDR5 overclocking performance of GPU memory.

Our second overclock is more of a "future potential" one as the chip can easily do it, but the cooling solution is utterly incapable of dispersing the heat produced. So once the AMD Partners bring out their tailored versions we should start to see overclocks heading towards 1GHz on the core.

Speaking of heat, this cooler is just not up to the task at all. It's woeful. But more of that in the conclusion, for now, 89°C maximum after an overclocked 3D Mark Vantage run should be enough to give you an idea.

Lol, this is a banging card. I would get it but I don't have over 700 bucks to spend. GTX 560 TI does me just fine.Quote

Once the 590 comes out and ATI drop this down to £500, it will be a no brainer.

I just hate Crossfire personally. Bloody CAP profiles and not being able to force your own AFR modes in the CCC and what not. If they sorted that out, i'd be all over this card.

And when will they introduce twin fan designs for reference cards? Would an extra £5 really matter if your dropping over £500 on a card anyways?Quote
