i am trying to revive an old P3-667mhz machine that has 1 stick of PC133
SDRAM - it has chips on both sides. If I want to add another stick, can I
mix it with a single sided or must they both be double-sided?

What if I remove this one and reeplace it with 2x single sided - will that
work ?

Check the manual for your motherboard.
Try any combination you like, most can happen will be associated with beep
at boot, if they are not compatible, try different ones.

It depends on the chipset. Some can not address high density memory
modules. What motherboard is it? That information should be on the web
site for that make/model motherboard.

You can try that. If it can't address the module, the system simply
will not boot.

I found a manual for the Asus P3V4X here
ftp://www.asus.it/pub/ASUS/mb/slot1/.../p3v4x-102.pdf
Is the double-sided stick also called "Dual-inline" - if so, then it seems
that's all it takes.

Thanks for the link. If you look at page 20 of the manual, you will see
that it will take up to 256 MB single sided modules.
"Dual Inline" refers to the type of module. DIMM is "Dual Inline Memory
Module". The motherboard uses DIMM's as opposed to older SIMM's (Single
Inline Memory Module). The difference is that SIMM's are 32 bits wide
and it takes two modules to address the 64 bit wide memory bus. DIMM's
are "dual inline", meaning that each module can address the 64 bit wide
bus.

ICee, please simplify:

Does DIMM refer to how the integrated circuits are installed on the memory
module? As in SIMMS have chips on one side only, and DIMMS have chips on
both sides? The answer to that may help clear it up for the OP.

The circuit board that the individual memory chips are soldered to is
the memory module. A Dual Inline Memory Module is one that can address
all 64 bits of the memory bus. It does not have anything to do with the
number of chips installed on the module. DIMM's can have chips on both
sides, or only one side of the module.
The motherboard in question can use PC100 or PC133 SDRAM (Synchronous
Dynamic Random Access Memory) DIMM's.
Does that clear it up a little?

Yep - I was pretty sure myself that that was the case, but you had been
providing excellent info so far, and felt it appropriate to defer to your
expertise :-) Hope you didn't mind me asking.

T.T.
