Overclocking Performance

The Radeon HD 5670 engineering sample provided by AMD was limited to a core overclock of 850MHz using the Catalyst software or a third-party tool like MSI AfterBurner. The memory was also limited to 1150MHz. This helped us achieve nothing more than an fairly average overclock, but we were still able to squeeze a few more frames per second out of our Radeon HD 5670 card.
