Corsair have had some good reviews recently, but this review of the latest OCZ offerring simply starts with the word "WOW".
OCZ have taken Samsung's latest 250Mhz ram chips and put them into a product that has a stock speed of 200Mhz. That means guaranteed overclocking headroom for all you enthusiasts. Couple this with OCZ's lifetime warranty on the memory sticks at Vcore voltages of up to 2.9v and you have a winner. The reviewer managed to get 275MHz stable at 3-4-4-8 in dual channel (1:1) mode out of these PC3200 sticks!
