I did try more than a week to pass 2.8ghz,but always got crask.update BIOS P31 still same sht,post around ,and reading,still no help .almost giveup then last friday just try to reset MBoard back to normal:set the reset jump,take off battery for more than one hour, try the last time set FSB 1250MHZ ,so it's ok then 1300,1350,and the last hit is 1400.PLease give me a tip to passthis point.I read and see alot people have E6300 hit to 3.8ghz,maybe some thing wrong with my chip/MBoard.
