Neoseeker has published a review of G.SKILL's revised PC2-6400 low latency memory
The G.SKILL F2.6400 4-4-3-5 memory simply dominated the stock (800MHz) results. This is an astonishing achievement considering the low price of these modules.G.SKILL PC2-6400 Review and Overclocking
I was also pleasantly surprised how much headroom it had for overclocking - it managed to reach 1000-4-4-4-6 whereas the previous revision I tested topped out at 975-4-4-4-12; and frankly that -6 latency is more important than the extra 25MHz it also beat its older sibling by. G.SKILL has definitely improved the quality of this module by a significant margin that you can benefit from.
