ha ha ha... I like the way you started your post, szwaba. Voltage aside... lol Consistant voltage is the key here. Yes, better quallity chips matter, but if you had better quality chips and dirty, inconsistant voltage, you would have very poor results. For any given MoBo, your best results will be with 2X2 because it can maintane the voltage better for 2 then 4 sticks. So basically for best results use the best chips and fewer of them. Voltage is everything!!!!
