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 slot1.
Populate 2, 4, or 8 DIMMs sequentially
beginning with slot 1. See "System
Memory" on page89.
DIMMs should be installed
in pairs. Pairs must be
matched in size, speed,
and technology.
