Is the lowerst latency PC3500 (and higher memory) still stick at CAS3? I'm thinking about buying an Athlon64 3400+ (since the 3700+ is so bloody expensive) and then trying to get another 200mhz out of it. Thats a slight overclock so I'm wondering if theres any low latency cas2 ram out there thats widely available that would be able to overclock comfortably to around 220mhz without losing its latency settings?
