I have had a few problems with my XFX Radeon 4890.
First, whenever I move the core clock above 870 (stock core clock @ 850) the card overheats and crashes within minutes. The card also overheats and I experience the vertical lines going down the screen. I have never RMA'ed anything before and I was wondering if anyone had any experience doing it.
Will they send me back another 4890 or a different card?
What will happen if they do not think anything is wrong with the card?
My previous RMA request expired (expired May13th) because I was hesitant to send the card back. Will this be held against me?
The card is only rated to be stable at its stock clocks, anything over that it a bonus. You can't RMA a product because its a bad overclocker. Why not manually up the fan speed on the card so it doesn't overheat?
I know my friend's 4890 crashes with even a slight overclock. I think this is normal.
Thanks for the info. I bought a new case (Antec 902) and everything runs 10C cooler. Like your friend, I can not overclock it at all. Although I have heard some people can overclock their 4890 with ease.
