Yeah, I've seen in reviews where the KT3 hit 200+ rock solid. I'm at 187 rock solid. 190 is 99% stable when I drop the multiplier to 9.5x. 193 seems to be where I max out. I was thinking it was my RAM because it was at maxed timings. Then I realized that the same thing happened when I switched to the most laxed timings. Still S.O.L. over 193. I can hit the BIOS at 200, but can't boot, and the screen is a bit messed up. Maybe AGP? Wouldn't think so, but I guess it is possible. At 200, it would only be running 80MHz. Then again, I haven't really tested for AGP bus stability with this card in another system. My hard drive sucks for OCing, but that wouldn't cause artifacting on the BIOS screen. Either system RAM or AGP card I guess. PCI is a possibility, but I only have a NIC in, and that NIC has been good up to 41.5MHz in another board...
