Hello, I realize this is a *very* old board so your patience is appreciated. I'm trying to upgrade the memory on my girlfriend's computer and ordered 2 x 1 GB PC2100 DIMMs. The max memory for this board is listed as 2 GB. Anyway, the first set they sent me won't post, so I sent it back. They sent me a new set and it wouldn't post with those either. What gives? Thanks in advance,
