Powermac 4400 memory RAM upgrade

It's again about time for me to upgrade the Powermac 4400's RAM

Please do not advise me to throw the machine away, I will not, it works
just fine with 96MB RAM, 400MHz, 40GB hard disk and DSL.

A question for the experts:

I intend to install one 32MB and one 64MB memory card.

Some cards which seem to fit the specifications are much cheaper than
those offered by Apple dealers. It may be that these are usually to be
found in Dell or IBM machines.

Can anyone help to clarify this?

Below p.s. I'll paste in the specification of the memory card which I'm
looking for, followed by a passage, in German, from the Macintosh 4400
handbook.

Cheers,

M Macpherson

p.s.
DIMM 64MB or 32MB, 168pin, 60ns, EDO 3.3Volt

WICHTIG Die DIMMs müssen 64 Bit breit und 168polig und nicht gepuffert
sein, dem Typ 3,3-V-EDO (Extended Data Output) entsprechen, mit
RAM-Zugriffszeiten von 60 ns oder weniger arbeiten und 1 K oder 2 K
Refresh unterstützen. Die DIMMS müssen aus DRAM-Bausteinen aufgebaut
sein, die eine interne 10 x 10, 11 x 10, 11 x 11 oder 12 x 9
Speichermatrix haben (Spalten x Zeilen). (...) DIMMs mit 4 K Refresh
können ... nicht verwendet werden.

Not quite sure what you had in there before to get 96 MB but I would
assume you have either 3 x 32 MB or a 64 MB and a 32 MB or 2 x 16 MB
and a 64 MB. Since you only have 3 slots you'll end up with either
128 MB or 160 MB. If it's an older 4400/160 the max you'll can ever
get is 96 while the newer 4400/200 will take a max 160 MB, the first
slot can only take single sided DIMMs or a 32 MB DIMM. But yes I've
used 3.3V EDO DIMMs from PCs that work fine. HTH
