Well, coming from the 600E world, of course I'm suspicious
about that. For a 600E, you need Low Density. Most PC100
memory is Low Density (but you have to check, there are many
compatibility lists in the archives of this list). PC133
memory is rarely Low Density, as JHEM points out.

OK, since I have the little baby open, I've taken out one of
the RAM sticks. It reads Compaq ... S0104 on one label.

On another label, stylized M (Micron?) MTBLSDT864AG-10EC7
PC100-222-620 SG CBNA7J3030 200019 64MB, SYNCH, 100MHz, CL2

There are 8 chips (so maybe this is high density, which would
be cheaper!) soldered on one side of the stick only

The chips themselves read:
0018 2-2
MT 48LC8M8A2
TG -8E C

The other stick is also 8 chips on one side, but completely
different labelling

SPECTEK (hologram)

P16M648LEA7 - 133CL3A
128 MB PC133 SDRAM
0138 N31577

128MB 168PIN PC133 AZENRAM
AAP0131
642-SPEC
10006468

and then the actual chips
D7 0138
S80016K7TW
-75A

and on the circuit board itself SpecTek 32S64A

So ... the conclusion is that at least some PC133 memory must
work on this computer, otherwise with only 64 MB working RAM,
it would be even slower than it is now!

>As for the Presario 192,

Sorry about that. What I was trying to say is that it is a
Compaq Presario presently equipped with 192 MB of RAM. It has
three RAM slots, of which two are populated at the moment. It
would be difficult to imagine that they are other than a 128
and a 64 MB stick.

The exact model number is 5WV277 - which doesn't appear in most
memory configurators, but I'm assuming that the close numbers
such as 5WV275 would also work.
