i think you are talking about the Bus clock for the ram module
it indicates the speed at which it interfaces with the motherboard
higher is typically better, but you also have to check the speed your motherboard supports...
in your case, the best way to go is to find out the clock on your existing 512MB memory, and when you buy the new module, make sure it's the same number (i.e. if it's 1066mhz get another 1066mhz module) this way you reduce your chance of things going wrong
Hope this helps (and i hope i'm no mistaken)
