I recently added memory to a Pentium 3 system for my boss. I purchased a 256 MB PC-133 RAM Chip and it worked just fine. But then I tried to add the SAME type of RAM to another Pentium 3 system but it didn't work. I found out that it took PC-100 RAM Chips. Why is this? I thought the type of memory you put in a system depended on the Processor you have; i.e.:
Old Petium = EDO
Petium MMX = PC -66
Pentium 2 / Celeron = PC-100
Pentium 3 = PC-133
I also found that my boss' computer also worked with PC-100 RAM chips, but this doesn't surprise me as much. Can someone please give me a rule of thumb of the kinds of memory out there and what types of systems use them. I also want to know the difference between ECC and non ECC memory and why it makes a difference? And I also want to know about the RAMBUS hype of a few years ago. Is that the FASTEST memory chip out there?
I will double the points if you come up with a thourough answer...
