upgrading RDRAM

[thirdchild]

I just got a refurbished dell that uses rdram

It has 2-terminals and 2-64mb
I want to upgrade to at least 512, but can i still keep using the 2-64mb's?

So it's either:
1)2-terminals and 2-256mb
2)2-64mb and 2-256mb

also does ecc matter?

So it only has 2 slots meaning you don't have any free.. or 2 slots free?

RDRAM has to be installed in pairs. If you have 2 total slots, you would have to remove what is in there and replace them. If you have empty slots, you can just put the pair of 256's in the empty slots and run them with the 2-64's already there..

excellent, thank you
i've got another 2 slots free so i'll drop in more ram

Make sure the old ram is PC800(400Mhz) ram(if it is not, then dump it and go with all PC800). Second you shouldn't have empty slots in a P4 rambus mobo...those empty slots need to be filled with CRIMMS.

CRIMMS are continuity devices that keep the frequency flowing through all 4 slots. They look like RDRAM with no chips on them.

I think that's what thirdchild ment by terminals
