Bit more testing...
I tried another PC with exactly same results. So I have now tested Pentium 3 1,266GHz and 486dx2/50 to be sure that it should not be related to ISA slot.
I also noticed that with Value card all simms are detected as 2 megabytes when I have jumpers set to 32MB or 16MB. But if I jumper setup to 8MB then I get 8MB and Diagnose goes through fine. Same with 4MB. But since I made these tests with my 486, I don't know how samples work (probably as bad as with gold).
I have now tried 13 different simms (and by different I mean different models). Few of them are not 32MB though. And about half are 70ns and one is 80ns. Still 6 are 60ns.
And 4 different simms have 16 chips AND 60ns speed.
One is this: https://www.oempcworld.com/OEMPCworld-com/003071.html
Another is this: http://www.memory4less.com/nanya-32mb-simm-ed … -nt511740c5j-60
One has same chips as this: https://www.classiccomputershop.eu/Webwinkel- … -retro-90s.html (so this is apparently fpm and not edo).
And then one had Panasonic MN414400CSJ-06 chips, but I can't find similar simms from internet. I think it is EDO.
Gold recognizes all these as 32MB, but in practise they don't work. Many instruments sounds broken and diagnose fails. If if jumper them as 16 MB then detect says 16 and diagnose goes through. Still samples are wrong (if I load larger than 4 MB sf2).
I used multimeter to test all connections on this simmconn and it seems to be fine (took some time). Also checked that resistor was what is was supposed to be. Capacitors look like ones that can be connected either side, but I'm not really an expert with electronics.
