I have a 486DX-100 that has 4 72 pin simm sockets on the board. According
to the user manual I can install just one 32 Mbyte 8X32 simm to give me 32
Megs.
Most of the 72 pin simms seem to be EDO Ram chips. Will there be a
problem using EDO ram in this computer? Also if I buy more memory do I
need to buy only EDO ram or can I mix them?
Should I expect any speed improvement with the EDO Ram?
Capt. John M. Zyla
You haven't provided enough information to answer your most important
question, "can they be mixed?" I have some 486 boards that do and
some that don't. Failure to mention EDO in the manual is not proof that
it won't work. You have to give it a try. However, if your CMOS has a
RAM type setting, you will not be able to mix ram types.
If you don't have a RAM type setting in CMOS, you can experiment to find
out what the board will work with. Fast Page (non-edo) 72 pin simms are
not hard to find. For a bonus to a friend, find someone who has Fast Page
installed on a Pentium and swap him for 2 16 meg EDO simms. You will
save a dollar or two and he gets better ram. Some 486's have the capability
to gain a slight performance boost from EDO, some don't.
