Overclockability

We wouldn't have expected any overclocking records even from a regular graphics card, let alone a dual-GPU one, under the hot weather we had during our tests. Anyway, we managed to speed our Radeon HD 6870X2 up a little without losing in stability and image quality.

The GPUs worked at a clock rate of 940 MHz. The graphics memory frequency was set at 4840 MHz. The temperature of the card didn’t change much at that:

The peak temperature of the GPUs was 86-89°C and the fans were but slightly faster compared to the same test at the card’s default clock rates.
