hi,
i have a r1.02 of the KT7A-RAID. and the XP1800 works perfectly on my MoBo. the only thing is that, it doesnt recognise the CPu correctly in the post, but it you go to the BIOS then set it like that, it`ll report it correctly everywhere, BIOS, POST, windows ect;
the fastest CPU is an XP2000 i think, or 1.6GHZ
