Re: Four CPU ES40 hanging
Where did you get the memory from?
This sounds very much like the memory buffer problems.
Bad date codes on the buffer chip (small chip about 2cm long in the middle
of the dimm) between 1998 and 38th week of 2001.
Caused many weird problems with the ES40 and ES45...
Nothing in error log - just hangs and requires reboot.
