Technical questions for the MPC2000xl and the MPC2000

About 6 months ago I upgraded (I think) my MPC2000 non-XL by getting 2 16MB SIMM's from Memory Masters. They are labelled and mentioned explicitly for the MPC2000.

At the time I never checked (I think) that they were working. I recently checked by SHIFT-SAMPLE and OPEN WINDOW and I saw Free memory(time): 21.9sec and 2mb available.

I did some reseating of the SIMM's and the best I got was 18mb, and this was one SIMM on the slot more toward the back. I never got 34mb and quite a few times (trying all permutations) I only got 2mb.

So I got a new pair from another place, that explicitly said they were for the MPC2000 (from SC). Same behavior.

I looked at the SIM slots and they are very clean. In fact my MPC2000 is pretty much mint.

Is there something I'm missing, and is there something that goes wrong with MPC2000's where the memory doesn't get recognized?
