Be VERY careful when OC'ing your RAM. DO NOT exceed 2.2 V unless you are
ABSOLUTELY SURE that the modules can take it. Unfortunately, you must keep
the RAM speed as close to 800 Mhz as possible when you raise your FSB. If you still
get stability problems use a lower setting. If you want to maintain the RAM speed,
you must relax the timings (latencies), something which I do not have much experience doing.
Notice, from
this pic I had to use a 'DDR2-736' setting to achieve stability at 3.3 GHZ.
I could have only maintained CPU speeds above 3 GHz by dropping the RAM speed to DDR2-667.
As always, use baby steps. Them 680i motherboards aint cheap.
