Very erratic weirdness with cod4,

5970`s seem to have issues with this game, if i overclock my 5890 1mhz more on core or memory then i start to get vsync weirdness where by everything will be sync`d apart from the top 3rd of my screen...

and just now when i went to play cod4 on default clocks i got this weird grinding every 15 seconds in game where by 60fps vsync`d will drop to 50s and back up again within 2 seconds.

here is some images of what my 5970s core and memory speeds where doing during game.

-------------------------------------

you tell me if thats not utter weirdness or a hardware or driver bug.

-------------------------------------

Default Correct 725/1000 3d speeds.

550/1000 ?????? why would 3d clocks be changing to this ??? its like the card is downclocking becuse of heat issues or throttleing even though the dam thing is wisper cool ???

Now this is just bloody ridiculous ? default desktop clocks ????

--------------------------------

As you can see by all the images all these clock changes are happning all at once when im playing cod4 default clocks ??? why would it be doing this ???? is this a hardware or a driver issue with this game ??
