On most K6-2 boards (MVP3, and I think ALi 5 based) your cacheable ram is
limited to 256MB. I am a very strong AMD supporter, but for this, I would
recomend a PII 333-350 (cheap, about $160 for a 350MHz PII), and a good
solid motherboard, an Asus P2B is very good for this (about $110), and use
4 128MB dimms (it will max your slots, but 256MB dimms are very
expensive), they are running about $80 each.
