In general the ECC reg parts will work, but not parity ones. Some of the later
systems wanted PC2700 and failed on PC2100, but I did not think the SB2500 was
one of them. The Red systems came with PC2100 originally if I remember
I would suggest buying a pair to try to start with unless the seller is
guaranteeing they work.
