Your post is OK in this forum, and here is some info:
1. Both the MSI 6378 motherboard model line, and the VIA KT133A chipset it uses, can actually support more than 512MB of RAM, but since your particular version of the mobo seems to have only 2 physical slots, 512Mb is all you get. The individual memory sticks are 168-pin 256MB PC100/133 SDRAM modules; pretty standard stuff.
2. The mobo doesn't have an AGP slot, so you're stuck with only PCI video cards as an alternative to the on-board video. PCI cards are getting harder to find, but the reviews in this article might help you find a PCI video card that fits your needs:
