Can you mix RDRAM chip size (i.e. 1x128MB with 1x256MB) in the same
channel on a Pentium III computer? Thank you.

Read your motherboard manual to see.

AFAIK, RDRAM must be matched. If not, you may only get 128 out of the other
chip. That is purely a guess....

I am unaware of any PIII systems (save for Xeons) that use Rambus memory.

Supermicro, among others I presume, made motherboards based on the i820/i840
chipset that would accomodate RDRAM with either a P-II or a P-III.

These are Compaq PIII AP250s. One channel/two slots only. Ugh.

From a response on the HP.COM forums, this is supposedly alright. As
long as they are both ECC. Speed is not even important (PC800/PC700)
as I have successfully mixed these on the same channel (running at the
lowest chip speed, of course). Thank you for your reply.
