Populating DIMM Sockets

Populate the DIMM sockets in the following order: XMM1, XMM2 or Channel A, Channel B.

first)	HP Pro 3405/3410/3500: Blue
XMM2 socket, Channel A	HP Pro 3400: Black	2

this connector as XMM3.

NOTE: A memory module must occupy the XMM1/Channel A socket.

The system will automatically operate in single channel mode, dual channel mode, or flex 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 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 one 1-GB DIMM 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
