Populating Memory Module Slots - HP EliteDesk 705 G3 Hardware Reference Manual

Populating memory module slots

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
1 Memory module slot, Channel B
2 Memory module slot, Channel A
The system will automatically operate in single channel mode, dual channel mode, or flex 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 flex 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 flex 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.
