HP ProDesk 400 G2 User Manual

Populating DIMM sockets (HP ProDesk 400 G2 and 480 G2 models)
There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates in memory channel
A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior graphics
performance.
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the DIMM
in Channel A is equal to the memory capacity of the DIMM in Channel B.
●
The system will operate in flex mode if the memory capacity of the DIMM in Channel A is not equal to the
memory capacity of the DIMM 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 DIMM in the system.
Populating DIMM sockets (HP ProDesk 490 G2 models)
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled
DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3
and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior graphics
performance.
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of the
DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology
and device width can vary between the channels. For example, if Channel A is populated with two 1-GB
DIMMs and Channel B is populated with one 2-GB DIMM, the system will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal
to the total memory capacity of the DIMMs 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. For optimal speed, the channels should be balanced so that the
largest amount of memory is spread between the two channels. If one channel will have more memory
than the other, the larger amount should be assigned to Channel A. For example, if you are populating
the sockets with one 2-GB DIMM, and three 1-GB DIMMs, Channel A should be populated with the 2-GB
DIMM and one 1-GB DIMM, and Channel B should be populated with the other two 1-GB DIMMs. With this
configuration, 4-GB will run as dual channel and 1-GB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
