"If you want the best timings at the highest speeds, then Golden Dragon is your ticket, if you don抰 mind the asking price. If you are okay with more relaxed timings then the list grows larger, as both TwinMOS and OCZ perform more then excellent. I know the OCZ has still quite a reserve left as these sticks clocked 250Mhz at CL2.5 3-3-7 on my Intel setup. Mushkin Blue PC3200 clocks up to PC3500 without much problem, as long as enough voltage is supplied."
