I've really enjoyed having this memory in my system. If you have a motherboard capable of such FSB speeds, I can think of no other memory currently, as reliable as Corsair's Twin-X4400. The name behind the label says it all, Corsair continues to meet the needs of the Overclocker, providing a high quality DRAM designed to acquiesce with Canterwood chipset, and especially on the Asus P4C800E-Deluxe. In writing this, my interest has piqued my giving this memory a turn on the Abit AI7 (hint). I think there are several motherboards out there which would suit this memory, and I'll be seeking them out for that purpose. While the memory is slightly expensive, you get what you pay for. While most of us probably can't afford the Aston Martin, we can afford its equal in the Enthusiast's realm of overclocking. And that has to give you a good feeling, and give it to you at 550 MHz!
