|The Q8400 runs at 1333MHz FSB (333MHz frequency). To get the DDR2-800 RAM to run in sync, it should run at 333MHz frequency (667MHz DDR), not 400MHz frequency (800MHz DDR).|
"I already pull out the battery and unplug the cord for a 10 minutes and nothing, I've used the 2 pins for clean cmos and nothing"
The power cord must always be unplugged 1st. And there's no reason to pull the battery if you have a clear CMOS jumper. With the cord unplugged, move the jumper to the clear position, wait a few seconds, then move it back. That's all there is to it. Waiting for minutes, hours, days, etc isn't necessary & won't make any difference...it only takes seconds.
BTW, have you revisited your other recent posts?
