Memory Population Sequence
Blue slots versus black slots: Install the first DIMM in the blue memory slot, which is the
first of a memory channel. Then, if using two DIMMs per channel, install the second DIMM
in the black slot.
The following memory population sequence table was created based on guidelines provided
by Intel to support Supermicro motherboards. The diagram is for illustrative purposes; your
motherboard may look different.
Memory Module Installation
When installing memory modules, the DIMM slots should be populated in the following order:
Memory Population for up to Eight DIMM Slots
Number of DIMMs
Memory Population Sequence
1
DIMMA1
2
DIMMA1/DIMMD1
3
DIMMC1/DIMMB1/DIMMA1
4
DIMMB1/DIMMA1/DIMMD1/DIMME1
5*
DIMMC1/DIMMB1/DIMMA1/DIMMD1/DIMME1
6
DIMMC1/DIMMB1/DIMMA1/DIMMD1/DIMME1/DIMMF1
7*
DIMMC1/DIMMB1/DIMMA1/DIMMA2/DIMMD1/DIMME1/DIMMF1
8
DIMMC1/DIMMB1/DIMMA1/DIMMA2/DIMMD2/DIMMD1/DIMME1/DIMMF1
*Unbalanced, not recommended.
Note: The motherboard supports installing an odd number of DIMM modules (1, 3, etc.).
However, installing modules in pairs provides best memory performance.
