Everything works fine at 2-3-3 but once I clock it to 2-2-2 all hell breaks loose and I Windows won't even load. Ummm...seems rather extreme to me but do you think the reason is because its a high density stick?...I heard that 512mb DIMMs are more sensitive or prone to error true?...Funny thing is it could boot at 160fsb at 2-3-3 and 2-2-2 but as usual at the latter setting Windows doesn't load. Would the performance difference be too small between the two settings?
