RAM Memory for Via Epia MII 12000

There are many kinds of ram memories, with different packages and speeds (see ram in wikipedia ), the Via Epia MII 12000 manufacturer specifications says:

RAM-Socket: 1 x DDR / RAM Type: DDR 266/PC2100 up 1Gb

Pc2100 and pc200 can be used, technically you can use PC3200 or above if you like, but there will be no performance advantage over PC2700.
The processor only has a 266 MHz front side bus, so theoretically PC2100 (DDR266) is all you need. However, PC2700 (DDR333) is often cheaper and more easily found than PC2100, and there can be a functional performance advantage in some instances; at very least, the PC2700 will clock down to PC2100 and go merrily along, so there's no harm in using a higher frequency memory module.

I have bought a 512MB PC2700 DDR 333MHZ Memory Module 184PIN (unknown manufacturer) throw eBay (22€), it works perfectly. Very easy to install, just plug in the slot until listen the "click".
