First, EDO memory only buys you about 5% over typical fast page mode memory,
as long as that FPM stuff is correctly mated to your processor/cache/etc.
(Top brands generally are, lots of others aren't.  We evalutate a lot of PC
systems and I think most people would be surprised at what we find...)

Upgrading directly to a P5-133 might or might not be a slam-dunk.  There are
a couple of considerations.  First of all, most 60Mhz parts are 5V - they
were the hot ones, remmeber?  I'm pretty sure all the 133's are 3.3V, so they
are not pin-compatible with older boards.  (I think new 75Mhz and up are all
3.3V.)  Even if your board IS 3.3v, upgrading your processor might or might
not be the best thing - if you have an old ISA expansion bus or a sloppy
video card, those might be your first target.  And although the data rate
on sound boards is pretty low (< 2MB/sec, probably a lot less), my experience
with video, network and disk interface boards tells me that there's probably
a large variance between sound boards in terms of processor consumption,
even for boards which are software compatible!

Agreed!

Err...The P5 60 seems not pin compatible with P5 133. Anyway, a new
motherboard is not expensive compare with a P5 133 chip.

Hi Brian,

The above being the case, can 70ns FP DRAM (72 pin Micron +parity) be

other M'board manufacturers state that 60ns is required for bus speeds

If one used 70ns, what would be the probable performance prognosis?

Simply put, do I need to upgrade my 36bit Micron 70ns 72pin FP DRAM
modules or will I be able to use them sucessfully to the Processor and
motherboards potential on either a Supermicro CMN or ASUS motherboard
with a P100 and PB cache?

Thanks.
