NO ENOUGHT MEMORY after installing the eb16 fx board

Hello Mpc Fam,
I have a problem again .. maybe someone can help me.
I cant load samples on my mpc 2000 after installing the fx board.
If i load a disk it comes the message No Enough Memory)

I dont understand why it dont work anymore.
Do i need a bigger memory ?

Best regards
Kurt ✌️

Can you say how much memory is installed in your 2000 at the moment? It'd be good to have a look at the memory strips inside as well if you can.
