Burst EDO RAM or PC133.
The board is a combo board. Is suggest that you use PC-133 2:2:2 aka CL2 or CAS 2. Only use one memory type. Only use PC133.

You can probably pick up a 256MB stick for around 30 bucks.

But PC133 will work, so try here... <A HREF="http://www.crucial.com/store/PartSpecs.asp?imodule=CT32M72S4D7E" target="_new"> unbuffered ECC PC133 CL2/CAS2 </A>
Good luck.
