With a bit of time taken to find the highest stable ceiling, we ended up with the clock rates that you can see below in the GPU-Z screen shot.

Overclocking the ATI Radeon HD 4890

We were able to move the default core clock from 850MHz to 950MHz, and we moved the default memory from 975MHz or 3800MHz QDR to 1100MHz or 4400MHz QDR. This is a pretty impressive overclock on both the core and memory; hopefully it will translate to a nice little performance increase in our benchmarks here today.

3DMark Vantage is the new industry standard PC gaming performance benchmark from Futuremark, newly designed for Windows Vista and DirectX10. It includes two new graphics tests, two new CPU tests, several new feature tests, and support for the latest hardware.

3DMark Vantage is based on a completely new rendering engine, developed specifically to take full advantage of DirectX10, the new graphics API from Microsoft.

In our first test we can see straight away that the overclock gives us a nice healthy increase in both the Extreme and Performance setup.
