■ If CPU model is 23xx, then the CPU count is 4 (for single-CPU server).
The single-CPU server configuration can be converted to a dual-CPU configuration
by adding a CPU that is identical to the one in CPU postion 0 and installing it into
CPU position 1.
For DIMM population rules for a single-CPU system, see Section 3.12.14.2, “Installing
DIMMs Into a Single-CPU System” on page 3-64.
