I can remember seeing this problem under WinNT on older computers (which had
earlier worked fine under Win31 or Win9x), but have rarely seen it on most
newer machines. I suspect that most memory now meets or exceeds any
specifications that matter, and so you can mix most of them without much
trouble. I even see mixing different speeds of memory (like PC100/133
or PC2100/2700/3200 - usually they all then run at the speed of the slowest
chips) without much problem. I have heard rumors of cases where it makes a
difference, but after servicing many hundreds of computers, I have rarely seen
any problems from mixing memory (unless you are doing silly things like
I have seen a few problems where it seems to make a difference which slot on
the motherboard you put the memory into. Actually, what seems to be the
factor is which slots you leave _empty_. Sometimes by moving the memory to
other slots, you can make problems go away. I'm not sure why this would be
the case. Perhaps just taking the memory out and in again results in cleaning
off the contacts in the socket (which is often something that helps -
epecially the AGP socket which has such small contacts).
