I just wanted to know if anybody knew anything about Kingston Hyper X. I am employed at a large electronics retailer, and we just recieved 512 Hyper X DDR500. I cannot find a board on newegg that says it specifically supports DDR500. Is DDR500 backwards compatible in machines that support only DDR400? and also, does anybody know why kingston can claim hyper x is the "mack daddy" RAM for gamers when the sticks we have are CL3?
