I currently have two machines each with 2 * 16 Mb 72
pin EDO RAM. (i.e. each has a total of 32Mb RAM).
The two sets of RAM are obviously made by different manufacturers. (i.e. one pair has chips on both sides of the module, and the other pair has chips on one side only.) I had heard that you shouldn't mix RAM from different manufacturers even if they are the same type. Anyway, as
an experiment I put the four sticks of RAM in one
machine to make 64 Mb. The machine certainly worked
faster. The only problem I noticed was that almost every
time I closed an application (browsers, word, excel etc) I
get a "This program has performed an illegal operation",
message. Although, I seem to be getting that a fair bit
even with 32Mb RAM since I installed Windows98 SE
the other day. ?
I'd like to run one machine with this combination of 64Mb
RAM and put some old Fast Page RAM (2*8), that I
have spare, in the other machine,(+ another 2*8 FP RAM that I'll need to buy) to make 32Mb RAM in the second machine.
The main point I'm getting at is: is it O.K. to just bung in extra banks of RAM like this assumming it's the same type BUT from different manufacturers?
As you'd be aware it's difficult to find out who made your RAM (at leastI think it is), and even harder to find exactly the same type especially if it's a few years old.
I don't really want to start all over again and buy new banks of 64Mb(EDO) for one machine and 32 Mb (FP) for the other. I'm hoping I can just combine the two 32's and just buy 2*8 Fast Page to add to the 2*8 Fast Page that I have spare.
Any comments or thoughts would be greatly appreciated.
Hope I have explained the problem clearly.
