Populating Dimm Sockets - HP Compaq dx2100 MT Hardware Reference Manual

Populating DIMM Sockets

Hardware Reference Guide
There are four DIMM sockets on the system board, with two sockets
per channel. The sockets are labeled XMM1, XMM2, XMM3, and
XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.
Description
DIMM socket XMM1, Channel A
DIMM socket XMM2, Channel A
DIMM socket XMM3, Channel B
DIMM socket XMM4, Channel B
The system will automatically operate in single channel mode, dual
channel Asymmetric mode, or a higher-performing dual channel
Interleaved mode, depending on how the DIMMs are installed.
■
The system will operate in single channel mode if the DIMM
sockets are populated in one channel only.
■
The system will operate in dual channel Asymmetric 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.
■
The system will operate in a higher-performing dual channel
Interleaved 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
256MB DIMMS and Channel B is populated with one 512MB
DIMM, the system will operate in Interleaved mode.
■
In any mode, the maximum operational speed is determined by
the slowest DIMM in the system.
