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 Table 2) 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
The following 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
IBM DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput.
IBM memory specifications are integrated into the light path diagnostics for immediate system
performance feedback and optimum system uptime. From a service and support standpoint, IBM memory
automatically assumes the IBM system warranty, and IBM provides service and support worldwide.
The IBM System x3750 M4 supports DDR3 memory. The server supports up to 48 DIMMs when four
processors are installed, with 12 DIMMs for each processor. 24 DIMM sockets (for processors 1 and 2)
are located on the system board. The remaining DIMM sockets (for processors 3 and 4) are located 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.
