ECC mode
disabled. For
128-bit Advanced
ECC, DIMMs must
be installed in
pairs. Pairs must
be matched in
size and
geometry.
The Advanced ECC option
was enabled in BIOS, but is
no longer valid due to an
unsupported memory
configuration, possibly a
faulty or removed memory
module. The Advanced ECC
setting has been disabled.
Check other messages for a
faulty memory module.
Reconfigure the memory
modules for Advanced ECC
mode. See "System Memory"
on page 130.

ECC Memory Mode
disabled! Memory
configuration
does not support
Advanced ECC
Memory Mode.
Advanced ECC Memory
Mode was enabled in the
system setup program, but
the current configuration
does not support Advanced
ECC Memory Mode. A
memory module may be
faulty.
Ensure that the memory
modules are installed in a
configuration that supports
Advanced ECC Memory
Mode. Check other system
messages for additional
information for possible
causes. For memory
configuration information,
see "General Memory
Module Installation
Guidelines" on page 131. If
the problem persists, see
"Troubleshooting System
Memory" on page 163.
