Re: bad memory?

2007-12-14 by esynthesist

This indeed looks like a memory problem.
The error message shows that 4 memory chips cause problems.
These are IC52, IC53, IC54 and IC57 on the main digital board (under 
the additional memory board).
It's a little bit strange that 4 chips on the same board row are 
damaged...

One of the known problems of the EII is ICs making bad contact/loose 
ICs.
Perhaps you can first push slightly on all memory ICs on the main 
board to make sure they are connected well...
