Compatible Memory

I have an Intel Easton D815EEA Mainboard that has three memory slots.
The existing 168-pin 128Mb stick of memory is marked PC133. If use the
criteria below at...

http://www.newegg.com/ProductSort/Su...ubCategory=147

....will I end up with only those items that are compatible with my system?

(I know from the the mainboard's specs that the max module I can get is
512 Mb.)

The Intel PDF above, appears to say that if I want to use a 512Mb
module, that it must be dual-sided. That option, however, does not
appear to be available (given my other criteria) at NewEgg. Is that right?
