Overclocking the Radeon HD 5850

We’ve had a fair amount of time to play with the Radeon HD 5850 now, and let us begin by saying that this card packs a serious punch. Even at its factory defaults, the 5850 offers significant performance, but it’s capable of so much more. To that end, follow along as we show you how to squeeze up to 25% additional performance out of your HD 5850.

As with all jobs, we need to begin by gathering the correct tools. While we can make a certain amount of progress with the Overdrive feature of the Catalyst Control Center, the imposed limits are nowhere near what the card is actually capable of achieving. To get around this problem, we’re going to need some extra programs.
Utilities

* AMD GPU Clock Tool: The AMD-approved overclocking utility which bypasses BIOS limitations.
* MSI Afterburner: Needed to control the card’s fan speed.
* Furmark: Stress-testing application for your overclock.
* Unigine Heaven: DirectX 11 Benchmarking tool.
