As assumed, there is something wrong with the 64MB block - it is 8 bytes too long and thus the last 8 bytes are actually not RAM. How does it enter the system? If this is an AddMemory, then I suggest to rather move the AddMem to the MMU-Configuration, and to size it correctly. The start should be $40000000, and the size should be $4000000 (count the zeros). If you really want to AddMem outside of the MMU-Configuration, make sure that MuFastZero and MuFastROM should go *behind* the AddMem.

PS: If you really want to set me up by being formal, it should be "Dr. Richter", then.
