If the original RAM works correctly and the new one won't at all, then take it back and get it replaced.
Hope this helps.
I just bought another 256mb of ram to go with the 256 that I already have. I installed the ram in its place but my computer still only shows 256mbs. I switched the two rams but still only have 256. I took the original 256 out and only put the new on in and the computer wouldn't boot. Both rams have a PC133 sticker so I assume they are compatible. Any ideas why I cant get the new ram to work?
