Sure, real tests are good. It would be great if you could test your new
SIMMs in both 605 and 63x and let us know (once they arrive).
OK, I got them today and put 64MB in q605 and 128MB in q630.
I have another set of identifying numbers too if you like
(no preference to any particular corporation, apparently
though my order was redirected ) you could search for also
64T8E164-60HYN AFE 64MB
128T16E164-60K0J-MIC AFF 128MB
neither card is apple or any other major manufacturer branded
and the individual chips differ between cards, but all say
"Korea"
both cards are double banked (unless I am confuse, i take
that to mean they have two rows of chips on a side, that
is 16 chips on a side). the 64MB is single sided and the 128
is double sided.
I wasn't really planning to try them the other way around
because I expect that the 128 would work in 605 and i am
more interest in whether the 64 would work in a 630 with
a second slot -- that is the missing one on mine which is
more toward the center of the motherboard. So could
you or someone else try one ???
Personally, I've tested a few hundred random SIMMs so far. See,
http://www.telegraphics.com.au/~fthain/dram/index.html
... the idea of this page being to help identify SIMM capactity -- not
compatibility (almost all work in Q650).
I don't trust generalisations like "composite SIMMs don't work" or
"single-sided don't work" or "double-sided work". What works and what
doesn't work ought to be determined by the structure of the chips
themselves (e.g. 1M x 4 chips vs 4M x 1 chips) and the number of those
chips on the module (given correct refresh rate and EDO/FPM).
well you could be right. but i do believe that some slots
are physically one sided (only) which particular
possibly your second
slot on the 631. have you used any double sided card
in the second slot ?
if you have seen the Apple Memory Guide, although the
capacities are outdated, it does discuss the single/double
sided issue some.

I have no 64 or 128 sticks to test. I will try to obtain some, but I'd be
more comfortable if I had the specs (chip count and chip part codes) of a
module that you or someone else had already tested!
I meant trying single sided 16 in first slot or double sided
32 in second slot. some these I pulled out of junk pile of
'97 pentium pc.
not just for yourself but for possibly others out there
who are contemplating these upgrades and wondering
about their memory. I have no two slotted machines to
test, but i would offer my spare cards if I thought they
could help someone. I do think for sure that 48 or 64 MB
for most users upgrading would help significantly.
But for people building or/and programming projects now
the real test ensues. my interest sort of between system
and user level. trying / retrying some compile/build will
take me a little while.
Although i did start up aptitude and it seems much happier
now it can grab 50MB.

I am sort of in the middle and hoping others will get theirs
working soon and give us some more examples.

Sounds like a similar problem to the one Raylynn reported with the
console... so maybe this is a fbdev problem not xorg...
there are three layers of fbdev. from xorg their fbdev and
their fbdevhw and then the fbdev from the kernel.
so far, if I boot in 640x480x16bit then the kernel admits i
do have 600k vRAM unfortunately xorg still refuses to
see it. If i don't see something pretty soon i will file bug
on xorg driver. maybe i will fly it by you guys though.

I don't know why that would be... does xorg understand the various
different ADB keyboards? I'm guessing, but I'd suggest have a close look
at the xorg.conf and failing that try xev and xmodmap.
well there are new keyboard stuffs in xorg that produces a lot of
errors though they never mattered on ppc I may have
to dig through that. I will try some things and
both of yours' suggestions
