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 if you have seen the Apple Memory Guide, although the capacities are outdated, it does discuss the single/double sided issue some.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. __________________________ In regards to the X stuff I am going to try respecting the starting of new thread for that. 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
