General Memory Module Installation Guidelines – PowerEdge M710HD
To ensure optimal performance of your system, observe the following general
guidelines when configuring your system memory:
• Memory modules are populated beginning with the socket farthest from
the processor (this socket is indicated by a white socket-release lever).
• In a dual-processor configuration, the memory configuration for each
processor must be identical.
• If quad-rank memory modules are installed, a maximum of two DIMMs
per channel is supported.
• If memory modules with different speeds are installed, they operate at the
speed of the slowest installed memory modules.
Three DDR3 memory channels are allocated to each processor. The number
of channels used and the allowable configurations depend on the memory
mode selected. The channels are organized as follows:
• Channel 0 - sockets 3, 6, 9
• Channel 1 - sockets 2, 5, 8
• Channel 2 - sockets 1, 4, 7
Sockets A1 through A9 are assigned to CPU1; sockets B1 through B9 are
assigned to CPU2.
Advanced ECC Mode Support – PowerEdge M710HD
In this configuration, channels 0 and 1 are combined to form one 128-bit
channel. If a memory error occurs on a given chip, the faulty chip is disabled.
Memory modules must be identical in size, speed, and technology in
corresponding slots.
Memory Mirroring Support – PowerEdge M710HD
The system supports memory mirroring if identical memory modules are
installed in channel 0 and channel 1 (memory is not installed in channel 2).
Mirroring must also be enabled in the System Setup program. In a mirrored
configuration, the total available system memory is one-half of the total
installed physical memory.
