ok guys i tryied to oc my q6600 and my computer failed to post so i reset the bios my rig is as shows and i run 4x 1gb dimms. the weird thing is that after clearing the bios the post screen would come up but wouldnt finish the mem test and lock. so i pulled out all the dimms except for one and i was able to get to the bios... on occasion the system would lockup while in the bios which i find very strange. because i didnt think the bios used ram. anyways i was able to get in the bios and save all the settings to defaults and reinsert all for dimms. i am currently running the vista mem test to see if its my mem thats cause any issues. do you guys think it could be anything else? i find it strange that after clearing the bios that the computer would lock while in the bios at all defaults so i wonder if its my mobo.
