question i currentlt have a dell demension 8200 PC400 MHZ FSB.

 

when upgrading memory do i need to buy memory that is DDR 400 MHZ SDRAM

or can i install a memory card that is higher example DDR466 MHZ SDRAM?

if i do install the later will it work?  and if so am i wasting money for getting 466 instead of 400

will my system run faster/better with higher MHZ memory? or is it a waste ?

 

Thanks
