Note:
The LS20 uses a minimum of 2 PC2-3200 DDR2 SDRAM Very Low Profile (VLP) DIMMs. The memory subsystem
is a 2-way interleaved subsystem; memory must be populated in pairs of 2 identical DIMMs per processor installed.
The two members of the set must be matched, but the sets do not have to be matched. The DIMMs should be installed
in the following order: DIMMs 1 & 2 (Set 1) with processor 1, DIMMs 3 & 4 (Set 2) with processor 2. The absence of
processor 2 will limit the potential DIMM slots to the pair pertaining to processor 1. The LS20 supports Chipkill. Mixing
Chipkill DIMMs with non-Chipkill DIMMs will disable all Chipkill function.
