DIMMs must be populated in
sequential order beginning
with slot 1. The following
DIMM is electrically
isolated: DIMM x.
The specified DIMM is inaccessible to
the system due to its location. DIMMs
must be populated in sequential order,
beginning with slot 1.
Populate 2, 4, or 8 DIMMs sequentially
beginning with slot 1. See "System
Memory" on page 89.
DIMMs should be installed
in pairs. Pairs must be
matched in size, speed,
and technology.
Mismatched or unmatched DIMMs
installed; faulty or improperly seated
memory module(s). The system will
operate in a degraded mode with
reduced ECC protection. Only
memory installed in channel 0 will be
accessible.
Ensure that all pairs of memory modules
are of the same type and size and that
they are properly installed. See "System
Memory" on page 89. If the problem
persists, see "Troubleshooting System
Memory" on page 120.

Single-rank DIMM - The
following DIMM/rank has
been disabled by BIOS:
DIMM x Rank y
Mismatched DIMMs installed; faulty
memory module(s). The system has
detected a dual-rank DIMM paired
with a single-rank DIMM. The second
rank of the dual-rank DIMM will be
disabled.
Ensure that all pairs of memory modules
are of the same type and size and that
they are properly installed. See "System
Memory" on page 89. If the problem
