I only said that catalyst said "passed", I am still finding the right speeds. And too comfort Slaymate a bit, the power management still works so it does not go that fast all the time. Currently I went down a bit again, cause when I went
higher than 680/1095 I got some black spots flashing up on the screen. Is that purely because of the clock speeds or is it (also) caused by a crappy appliance of the thermal grease?
@ raizen: if you wish too improve your cooling performance you will need a dual slot cooler like the Scythe Musashi I used. About the screws: Most likely there are three screws underneath the fan, for which you'll need a philips screwdriver to get them loose. And you let it sound as if it is 10 minutes job to release the old cooler, which it is not. I think you should read
this thread on A4T ("Chevalr1c" is me actually) and pay special attention to $Solid$ Necro's and BuffaloChips' remarks. Necro is right about the time you need for the disassembly I think (it took half an hour in my own case). And Buffalo makes a point about the wobblyness (though the problem is exagerated on other websites, it is still nasty when putting the card into the case).
