Thanks for your reply,

Let's see if i understood....You're saying that i can get PC3200 (400 mhz FSB)DDRAM modules and place them into older mobo even if they don't support these speeds? I understand that i can not place 333MHZ and 400MHZ DDRAM modules together for example, they're not compatible and system won't boot, is that correct?

Would I place PC3200 DDRAM modules into older mobo and will work ok??

Thanks,

Jim.
