Can I use FPM RAM in place of EDO RAM?
I want some back-up opinions please: Can I use FPM RAM in place of EDO
RAM?
I've seen one comment that FPM RAM can work in EDO-capable motherboards.
Does anyone have a contrary opinion?
What is the electrical difference between EDO and FPM RAM? I understand
the functional difference: just need to understand the electrical
difference between two different sticks.

thehobbit....as far as I know you can use FPM in place of EDO. Also,
as far as I know there are no significant electro/mechanical differences
between the two. They are both DRAM. EDO being one technological step
above FPM. EDO offers no real performance benefit over FPM.
The best you can expect would be a 5% increase in system speed using
EDO. You would probably really see less than that. EDO must be supported
by the motherboards chipset. The one difference maybe in the bus speed
of the motherboard. FPM usually would run under 66mhz bus speed and EDO
can run as 75mhz I believe. So you might have to do some fiddling around
in the BIOS if the FPM doesn't like to run in the motherboard. Increase
the wait state value of the DRAM in the BIOS if the FPM does not run
well. Try and use all memory modules of the same make and speed. If
that's not possible then put the slowest one in SIMM bank one. Some
motherboards may even allow you to mix FPM and EDO together. But the EDO
will most likely run as if it were FPM. Hope that helps.
I did purchase 64 Mb of FPM RAM and installed it into an HP XP/60. A well as I can determine,
it seems to work fine. I'm satisfied. (thehobbit )
