 From some checking, the intel 810 takes up to PC100 memory.
Here is a link to the PNY page:

http://www.pny.com/configurator/

If you cannot find your MB number, do a search on a Intel 810E.

Notice the note on the home page about PC133memory being no longer
backward compatible with PC100. SO i would say you need true PC100
memory. Maybe some further checking on single or double sided chips
would be in order to. Some poking around the Intel site on the 810
chipset specs might give you some more ideas.

Also, i would strongly advice upgrading your Windows XP to SP2 and all
the latest updates.
