| Failing Memory Modules on Mod. 56 / 57, 76 / 77, 85 and 90 / 95 |
Assumed you get a memory error in the Format 0002XXSY you could find out the failing module with this chart below.
The -X- in the error-code can be any number, -S- marks the position of the memory socket, -Y- determines the module type, size and access-speed.
