I can bench at 305MHz fsb with the 5:4 ratio till now and STILL moving on.........I think one of these days I'll found out why those ABIT's can't go higher than 280 - 290MHz average fsb's with the 5:4 ratio.......I'll post the "findings"..........I'll borrow a digicam from a friend of mine one of these days(haven't bought one of mine yet).......
