Hi Duncan,
EDO dimms came in two versions, both 168Pin. You could have 3/3.3 volt,
and 5 volt EDO dimms.
Finding EDO dimms over 64MB can be hard, and over 128 MB without being
registered ECC (both must be supported by the chipset). Most chipsets
of that time could only address 64mbit
Harry,
Thanks for the informative reply. I'm still thinking about some of it.
To answer some of it,
a) believe the memory voltage is 3.3vdc.
b) the motherboard is a dual Pentium Pro from Micronics with only
one Pentium Pro 200.
c) the chipset is the 440FX.
d) the PC is a Micron Millennia
OK so I have a really old machine. I'd like to think that it might be PC66
but now I'm not
so sure. It is EDO ram. NOT SDRAM.
Got some new DIMMS today, but they do not fit. They were/are SDRAM. At least
they are
based on where the notches in the DIMM(s) are. Have RMA needs and is in
The first EDO were on SIMMS = Single Inline Memory Module = FPM (Fast Page
Mode) and EDO (Extended Data Out) that improved the speed of FPM. Most
earlier EDO SIMM boards you could run either FPM or EDO SIMMS, but you were
advised not to mix them. EDO SIMMS have to be run in pairs.

WinterLight,
Thanks for the trip down memory lane. Excuse me.
I do know just what I have.
They are not SIMMS.
They are DIMMS. 168 pins. Notch spacing is the important part!
No, I do need EDO DIMMS. With 168 pins, AND, the spacing twixt the center
notch and the edge notch to be correct. It's
