Corsair PC4000 DDR500 TWINX2048-4000PT 2Gig Dual Channel Memory Kit
 

"This two gigabyte kit from Corsair again is just a perfect example of a quality product. It is relatively inexpensive, performs well and is rock solid stable. As for the 3-8-4-4 timings, if you overclocking at all, don't even bother considering it a disadvantage."
