I picked up a GVP Impact Series II 030 Combo card. I believe it is this one:
http://amiga.resource.cx/exp/search.pl?dir=a2000proc#combo
The page mentions it uses special GVP SIMMs. What is different/special about the GVP SIMMs? When I picked up the unit from the guy he had it powered up and it appeared as if it had 32 MB fast RAM. At home I removed everything to clean it up. I put the GVP 030 back in and booted and now all I have is 8 MB fast. The only other cards in this unit (2000HD) are the Commodore card with a hard drive attached and an AT bridgeboard. Do either of these have what should total about 24 MB of fast RAM on them? I could put the cards in one at a time and see what happens.
Also, I booted off a 3.1 install floppy versus the hard drive. In other words, when I saw 32 MB fast RAM this system was booted off 2.04 with KS 2.0. WHen I saw 8 MB I had replaced the KS with 3.1 and booted off a 3.1 floppy. Is there some software required to use the full 32 MB? I am new to the GVP accelerator so I am not sure.
Thanks in advance. :)

That board can only ever have 16Mbyte of FAST RAM. Only 8Mbytes of that is Autoconfiguring.

You need the driver to access the extended 8 mbytes

Every GVP board I've ever had autoconfigs all of the accelerator memory, it's built into the faastrom on the board. The maximum on that particular board is 16mb if it has 4 of the 4mb gvp 64-pin simms. The maximum ram installable in a so equipped A2000 would be 24 if you installed an 8mb ZII ram board like an 8-up or GVP HC+8 board fully populated. This of course is going to eat up all of the ZII card autoconfig space so a bridgeboard or graphics card is going to conflict. Better to install only 6Mb of ZII memory on such a card.
