How to Force Max clock speeds (ATI Cards)

[Phazon]

The bug is present for single AMD cards as well. My HD4870 does not clock up at all for Cliffs of Dover, and it is the only game it has ever done this with. As noted above, this can easily be shown using GPU-Z and sensor logging. This is using the latest 11.3 drivers.

Using Overdrive in the CCC will not work. It does not disable PowerPlay which is what controls the up/down clocking feature of the card. I'm not fully aware of the extra driver features available for Crossfire users but for single-card users this will not work at all.

The main workaround for single-card users at the moment is using a third-party overclocking utility like MSI Afterburner. It has to be a utility that is capable of overriding PowerPlay with custom clock settings. I also found with Afterburner you had to set clocks with a 1Mhz difference to get it to apply.

Anyways this is a significant issue that has yet to be officially acknowledged. The US launch is getting closer and even more AMD users will be playing the game. It needs to be fixed soon.
