My old hardware was boxed up for 6 years or so, I've moved twice during that time. Just unpacked and trying to get everything working again. Plus I have some new additions.

I have a SIMM in the slot next to the edge of my SB32 (CT3600). I definitely did have it working at one point about 6 years ago, just not sure if my driver installation got broken or of there's a problem on the card. Also don't remember if there was a 2nd SIMM in there, it wasn't in the box but I should have some elsewhere.

The slots aren't numbered. What should the troubleshooting steps be?

I do get sound effects and AWE32 music in Doom.

AWE Control Panel says 0kb memory, and threw up a message about failing to load the .sbk I used to have in there.

I'm pretty sure the SIMMs need to be installed in identical (same capacity at least) pairs on AWE32/SB32 cards

EDIT: TBH, I've always successfully used pairs and the manuals I've found are very ambiguous about whether a single SIMM could work .

Seems you are correct, I found and inserted the other SIMM, it detected 8MB and loaded the soundfont file.

The cards definitely need pairs of same sized SIMMs, single one will not work as it only provides 8 bits and the entire 16bit bus needs to be filled. Sort of similar situation as with 386SX vs DX, one needs a pair for its 16bit bus, other 4 for its 32bit.

Yes, it needs pairs.
But I have experienced that after almost 30 years the sockets tend to break when you try to remove the SIMMs.
But 8 MB is a good choice.
