Hi everyone, I am using a home built system. I have built five systems already and this would be the first one I’m having memory issues with. I have 768 megs RAM. After boot up, with no start up programs, i’m down to 80%. I take another system with the same RAM with no start up programs and get 94% and it stays pretty much that high through much abuse. Mind you, same programs and everything. There is one diffrence between the two and that is the one I’m using now has a Zip250. I have done a tonof reading and not any where could I find anyone having a memory problem just because of a drive. Any suggestions would be great. Thanks a million.
