I was attempting to give my dad’s MPC an overhaul, updating the internal memory and changing the pads. Unfortunately now when I turn the machine on it attempts to boot in SODIMM memory check mode and fails to load.

It gives the following error message- “The problem was found in the memory. Please check the memory. System halt…..”

Has anyone else encountered a problem like this before or is there another forum that has trouble shot this issue? :hmmm:

I’m wondering if the memory hardware i installed was faulty or otherwise incompatible.

Please help me fix the ghost in the machine!! :worthy: :worthy: :worthy:

Hey JRex,

I've experienced the same. You should check the RAM. Maybe it's loose.
Open the lid o the back and gently pull the ram-extension out, then softly squeeze it back in. After that try to start up again.

I hope this helps.
