Processor options
The x440 supports the processor options listed in the following table. The server supports one or two or four
processors (three processors is not supported). For a given processor model (for example, the Xeon E5-4603), there
are two part numbers: the first one is for the rear two processors (CPUs 1 and 2) and include taller heat sinks; the
second part number is for the front two processors (CPUs 3 and 4) and include shorter heat sinks.
The table also shows which server models have each processor standard. If no corresponding where used model
for a particular processor is listed, then this processor is available only through Configure to Order (CTO).

Memory options
Lenovo DDR3 memory is compatibility tested and tuned for optimal performance and throughput. Lenovo memory
specifications are integrated into the light path diagnostic tests for immediate system performance feedback and
optimum system uptime. From a service and support standpoint, Lenovo memory automatically assumes the
Lenovo system warranty, and Lenovo provides service and support worldwide.
The x440 supports DDR3 memory. The compute node supports up to 48 DIMMs when four processors are installed,
with 12 DIMMs for each processor. Each processor has four memory channels, and there are three DIMMs per
channel.
The following rules apply when selecting the memory configuration:
The server supports UDIMMs, RDIMMs and LRDIMMs.
Mixing different types of memory (eg RDIMMs and LRDIMMs) is not supported.
Mixing 1.5 V and 1.35 V DIMMs in the same server is supported; in such a case, all DIMMs operate at 1.5 V.
The maximum number of ranks per one channel is eight (with the exception of Load Reduced DIMMs, where
more than eight ranks are supported, because one quad-rank LRDIMM provides the same electrical load on
a memory bus as a single-rank RDIMM).
