Populating SODIMM sockets

There are two memory module slots on the system board, with one slot per channel. The sockets are labeled

DIMM1 and DIMM3. The DIMM1 slot operates in memory channel B. The DIMM3 slot operates in memory

channel A.

Item Description System Board Label Slot Color

1 Memory module slot, Channel B DIMM1 Black

2 Memory module slot, Channel A DIMM3 Black

The system will automatically operate in single-channel mode, dual-channel mode, or ex mode, depending

on how the memory modules are installed.

●

The system will operate in single-channel mode if the memory module slots are populated in one

channel only.

●

The system will operate in a higher-performing dual-channel mode if the memory capacity of the

memory module in Channel A is equal to the memory capacity of the memory module in Channel B.

●

The system will operate in ex mode if the memory capacity of the memory module in Channel A is not

equal to the memory capacity of the memory module in Channel B. In ex mode, the channel populated

with the least amount of memory describes the total amount of memory assigned to dual-channel and

the remainder is assigned to single-channel. If one channel will have more memory than the other, the

larger amount should be assigned to channel A.

●

In any mode, the maximum operational speed is determined by the slowest memory module in the

system.
