755 machines with 00201 internal RAM error...?

#1 Post by solidpro » Mon Sep 27, 2021 1:15 pm

Hi

I've come across a few 755 machines which come up with an 00201 error, which is not related to the IC DRAM card - it seems to be related to the built-in RAM on the mainboard.

Has anyone ever successfully repaired or resolved this issue?

Thanks

Alex

Did you run the Easy Setup Diagnostics on the base memory (with the IC Dram card removed), or did the error message show on the boot screen?

Hi

It shows on the boot screen even with the IC DRAM card removed...

Thanks!
