Hello and welcome to techimo!

Is this your board?

Mercury-pc.com

If so, it supports up to 3gb of SD memory.

As per their site;

"Memory -Three 168-pin DIMM sockets for 3.3V SDRAM (PC133/PC100)
- Maximum: 3GB"

So it appears to support strictly SDRAM

For example;

Amazon.com: pc133 sdram 512

Though personally I wouldn't drop more than 1gb in a system like that..

I can't foresee anything you are doing justifying more than 1gb of that slow of memory (to be honest I didn't even know they still sold it ).

This site will show you the differences between DDR and SDRAM.
