I have the Radeon 64meg DDR VIVO (5.5ns ram). I can clock it at 212/212 without any probs. Anything greater than that starts corrupting the screen with purple lines, mainly when it's clocked at 215/215 or above. I have it running at 200/200 now because of the degrading performance issue, but it actually seems to gain more fps as it's clocked higher than 200/200. I put a blue orb and ramsinks on the board, which may be overkill, but I like voiding my warranty so it's cool. Anyway, what are some good overclocks people have been able to get with the Radeon? I've heard of 220/220 on a 32 meg version (6ns ram), but this seems high.
