Processor options

The x3750 M4 supports the processor options listed in the following table. The server supports up to four

processors. Two processors are installed in sockets on the system board. Processors 3 and 4 are installed

on the processor and memory expansion tray. Most models (with the exception of A2x, as listed in the

Standard models

section) have the expansion tray installed as standard. For model A2x, order part number

88Y7365 for the processor and memory expansion tray.

The following processor quantities are supported:

One processor, installed in socket 1

Two processors, installed in sockets 1 and 2

Four processors, installed in all four sockets

Note: Configurations with one processor doe not support internal storage.

The table also shows which server models have each processor standard. If there is no corresponding

where-used model for a particular processor, this processor is only available through CTO.

Memory options

Lenovo DDR3 memory is compatibility-tested and tuned for optimal System x performance and

throughput. Lenovo memory specifications are integrated into the light path diagnostics for immediate

system performance feedback and optimum system uptime. From a service and support standpoint,

Lenovo memory automatically assumes the system warranty.

The Lenovo System x3750 M4 supports DDR3 memory. The server supports up to 48 DIMMs when four

processors are installed, with 12 DIMMs for each processor. There are 24 DIMM sockets (for processors 1

and 2) on the system board. The remaining DIMM sockets (for processors 3 and 4) are on the processor

and memory expansion tray. Each processor has four memory channels, and there are three DIMMs per

channel.

The x3750 M4 memory system has been carefully tuned so that the server supports higher memory

frequencies than the Intel processor specification. You can, for example, use low-voltage DIMMs but still

operate them at the rated speed.

The following table lists the memory options that are available for the x3750 M4 server.
