So what do you reckon then:

Those black bits tend to flicker very fast and are random, it also happens in BF2.

I've tried checking the cooler, installed different drivers but the result is the same.
 
Just stock speeds never bothered to OC it, I figure it might be the memory or something.
 
Yeah I had already tried some drivers just to make sure but it still turned up.

I do sometimes wonder if the memory is getting to hot, the fan doesn't seem to speed up much and the chance of me tightening the plate any more isn't likely.

The screws on the back of the card are just ****, just another set of soft heads it seems however I've checked and also tightened them a bit. Going to do some more testing tonight to see if it has helped, I'll also drop the clock speed down if problem reappears.

As for the games while WoW, BF2 and OpenTTD are my main current ones I could check on games such as L4D2, Crysis Warhead, etc but it isn't really needed at the moment.

It is outside it's RMA period and if it comes down to it I'll use my spare 8800 GTS card for a while then get a ATi 5870 or something.
 
Well in WoW I've tested alt-tabbing out and reduced the Memory/GPU clocks, after some more testing it seems reducing the memory clocks results in the black blocks not appearing.
 
I'll have to test some more to find the exact figure although my base to find out was a drop from 900 to 725, although it did appear slightly less when using a clock between the two.

The card is clean, airflow is ok as well although I still can't shake the feeling the issue while being related to heat isn't purely down to it since the way the card acts in terms of load.

Getting the cooler of again would require me to drill one of the screws as well.
 
It is outside RMA anyway, the screws just seem so soft.

I still feel there is something deeper, it just doesn't seem to appear for a while at times.
