That would not really make a difference. I've tried it once on my EPIA
boards, and ran some custom benchmarks. I didn't notice any difference
at all. It's really not worth it for most practical uses.

Yes, more RAM is always a good idea. But if you're using EPIA 5000 boards,
you should be aware of one catch: use just one of the two slots (you can
use one 512 MB PC-133 RAM module, but not two modules!), because these
boards can't reliably drive both for some strange reasons.
