Yeah....both of us has the same problem.
So mine is not an isolated case.
Was thinking of returning it back to the shop.
Now i don't unlock the ATI Overdrive, everything seems to be fine.
Maybe will try the new drivers and see if it still happens
thks

I'm well aware that crashing during overclock is normal.
If you have read my earlier post, then u'll understand my problem.
Calling ppl stupid without understanding their problem is pretty stupid to me.
Try to read ppl earlier posting to gain an understanding.
Sorry, I wasn't saying you're stupid. The reasoning is. A play of words is a habit of mine

.
Now then, from what I see, this is all about overclocking. Overclocking is not covered by warranty. There, I read your earlier posts, so what are you telling me, if not overclocking? That's why I said your reasoning is stupid.
Well anyway, overclocking 101. If you overdo your oc's, your chip will get 'soft' and will overclock less. I OC'ed my 4890 to 950 MHz once(plus voltmod. My chip sucks). Green patches of artifact starts appearing, which won't dissappear at whatever clock. A restart made it go away though.
What you are seeing are artifacts when your overclock. Some of the shader cores are generating errors when running at such clocks, and those errors show up as artifacts. I heard white artifacts are memory artifacts, while other colours belong to the core. Never tried to prove this though.
