hmmm - then go for the OCZ DDR3 modules they come in kits and they aso come optimized for AM3 - i think. the platinum editions have tight timings. One more thing - asus have a small issues when using ram to its ultimate level, they either hickup or cause minor headaches. u'll b fine with 8GB quad kit - here:http://www.ocztechnology.com/products/ddr3/platinum_series
btw get the one that has the same bus speed as ur processor.
1more thing - lemme know how it works out - i mite get one myself
and mayb learn a few modelling tips form you.
