at all, as far as I
32 Meg modules are not stackable. 24s and smaller are. Even though the Max RAM
in that slot is 48, it must be done with either 2-24s or a single 48 module. Why?

Simply not true. I have configured many 1400 with a 16 and a 32.
Some Ram module are not stackable at all, they lack a pass thru connector.
I have heard of problems with certain 16 and 32 not working
terrible buy per Meg and not worth the investment for the tiny gain. RAM

has a better bang for the buck, allowing triple the RAM under OS 9.1, without
slowing them very much.
I've not tried RD on my 1400 (well, ever, really, ); does the MacOS see it
as real RAM or as virtual mem that
i've not tried RD on my 1400c/G3, but I do have it on my an 040 610 machine running
8.1 with only 8 megs of ram. It allows me to run Office, Netscape, and MacHTTP on it
rather solidly. I think it uses some sort of RAM disk-like thing for the vm, but not
certain.
I've had trouble with it

What
I've tried VPC 4/ME on both of my 1400/G3s and found that it wouldn't work. I
originally assumed that it was because RD is a VM, although much quicker and more
efficient than Apple's VM. I since have heard of many people having trouble with
PBs that had Sonnet G3 upgrades refusing to run VPC.
You must have always gotten the good modules and I the bad. I have never been
able to get 32s to stack with 16s. I also have never had a problem with the
16Meg Apple RAM and stacked 3rd party modules that others say they've always
had. There must be some real extremes in the production of the 3rd

Perhaps those modules lacking the pass through connector are

YES ! if they don't have a passthru they
RD is basically a Virtual Memory program that works better than Apple's. (I'm sure
someone can jump in to explain exactly how it does this.) It has the same
limitations with opening some apps, although others treat it as real RAM (very
slow real RAM!!!)
I'd check with people on the LEM Swap list

With caveats.
Ram Doubler worked well up to about OS 8.1, but Apple made considerable
improvements in VM with 8.6 and up, at which

nope, I have an extra 16 meg chip that would put me at 64, but the stupid

I own a stackable 32meg card for the 1400 (plug on top and bottom). And it's
stacked 32 on the bottom and 16 on top and works fine.

from Apple's knowledge base:
Possible solutions:
1) Try reseating the memory card. A memory card that has become
unseated will give this error.
2) Apple has worked closely with developers of third-party
(non-Apple) memory upgrades and have identified timing issues between

I don't know where they got that idea. I have a PB 1400c (w/Nupowr G3
250mhz upgrade) that has 16mb on the mobo and two stacked 24's, for a
total of its max of 64mb. Works fine.
I think it matters how much you started with. Did yours have 16Mb factory
installed?
Mine was a 12MB factory
before my sonnet, it wouldn't boot up at all with both stacked, but as you
pointed out, I had the 32 on bottom and the 16 on top.
Do you really think it may work in reverse?
actually, I think t32 isn't stackable.. I'm on the machine now... I'llhave

with the Sonnet 333 card: it boots but doesn't recognize the 32 chip on top
of the 16, total ram shows as 32 megs
with the original 166 603ev (?) in it: won't boot with 32 mb chip stacked,
