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.

I encountered this problem running windowed games. It would not kick my HD4870X2 into full speed unless I was running a full-screen game. You can disable the power-saving crap by editing the profile file and changing some settings. My card runs at max speed 100% of the time now.

Edit:
Win7: C:\Users\<user>\AppData\Local\ATI\ACE\Profiles\nop owersaving.xml

I changed all the "Want_0" values to be the same as the "Want_1" values. You could also try playing with:

<Feature name="ForceHigh3DClocks">
<Property name="ForceHigh3DClocks" value="Disable" />
</Feature>

P.S. There's a chance you could fry your card, be careful what you change.

It's very difficult that the card downclocks if it has work to do, performance on modern gpus it's very delicated, example: pes2011, doesn't use more than 25% of my gpu, and i had mad stutter, vsync on. Incredibly, it was because frame skipping was turned on, while frame skipping is intended to keep everything running in real time, it severly downgraded my performance.
Unluckily, it seems we would need patience from both developers of cod and amd driver team.
I need extra doses of patience, since my damn ptc doesn't deliver my money, exactly 50U$S after 14000 clicks i've made last year preparing to buy cod -_-

- The clock issue has nothing to do with single / crossfire setups.
- The way described in the videos doesn't work for newer revisions of either cards or drivers.
- AMD Overdrive does not OC the card at all times. It still clocks down and just goes up higher under full load
- You can use a simple tool called "System Monitor" from AMD to check if your card is going to it's maximum clock or not. It shows everything nicely. It's most likely already installed on your machine. Just press the windows key and type: "system monitor" and wait a couple of seconds. Or you can just download it here

I have MSI afterburner, but I can't find any setting to override powerplay. I also don't know what you mean by "set clocks with a 1Mhz difference", could you be specific?

Having exactly the same problem with a single 6850 running the newest drivers. This seems to be a major game-breaking bug, Clocks remains at 300Mhz. Does not matter if I'm playing windowed or fullscreen, thus I get dismal framerates with the game, even on lowest settings.

Quite unacceptable for a game supposedly in development for six years.

With ATI Tray Tools you can create a profile for a game with desired clocks and run it together with the game from a shortcut.

Did everybody skip straight over my post in which I explain exactly how to force maximum clock speeds using CCC?

Some people experiencing this issue had it resolved by checking that the flash player does not have "enable hardware acceleration" checked.

This for some reason in CoD prevented your card running at 3D speeds.

That was my problem, and it runs as intended now.

ATI tools just made my system crash for some reason.

I didn't skip straight over it, but you did put me off:
