Overclocking

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.

   

Temperatures

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.
