Memory Population Recommendations

Table 16 shows the preferred order for installing upgrade DIMMs, and while other configurations may work,

if problems arise, moving them to the preferred arrangement should help. Note that the bank installation

order is Bank 1, Bank 3, Bank 2, Bank 4.

NOTE: DIMMs installed in slots for an absent CPU are not recognized.

populated with identically matched DIMMs that were ordered as a pair. Do not swap a paired

DIMM with a DIMM that is not identical in manufacturer part number.
