What exactly happens (or doesn't)?
What other expansions do you have in your A2000?
Have you tried the kipper expansion with Zorro cards removed?

Hmmm... just read BBOAH and it says it's just for the A500. It wasn't mis-sold then at least.

I installed kipper 4 MB expansion to the CPU socket, no Zorro II or other card. Boot from floppy OK, 1 MB chipRAM, 0 MB other mem. The machine work, but 1 MB only, no CPU contact problem.
The kipper card work OK with A500.
All kipper cards work with A500, 2000, 1000. IDECF+fastRAM. The simple fastRAM expansion why not?
