Adding RDRAM to Dell Optiplex GX400

Hi all,

I got a Dell Optiplex GX400 for cheap that works great and is surprisingly fast... however it uses RDRAM which I know very little about.

The GX400 came with 128mb installed (64mb PC600-53 x 2) and I bought two additional 64mb PC600-53 sticks via Ebay that I tried to install bringing the total up to 4 sticks / 256mb, but the computer won't start with them added and the BIOS beeps heard refer to a mismatched RAM issue.

The four RDRAM modules are all 64mb PC600-53, so I'm confused. Any ideas?
