What do you exactly mean with "options"? Options to use the memory which
is not supported?
Looking at the CPC945 documentation it says it supports x4, x8 and x16
DIMMs. Unfortunately I do not know why the code says it only supports x4
DIMMs. So I would say buying more memory is your only option right now.
