HP EliteDesk 705 G4 Desktop Mini User Manual

Installing memory modules
There are two memory module slots on the system board, with one slot per channel. The slots 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 A DIMM3 Black
2 Memory module slot, Channel B DIMM1 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.
