Lenovo ThinkServer sd350 - Memory Options

Memory options
TruDDR4 Memory uses the highest quality components sourced from Tier 1 DRAM suppliers. Only memory
that meets the strict requirements of Lenovo is selected. It is compatibility-tested and tuned on every
server to maximize performance and reliability.
The ThinkServer sd350 supports up to eight DIMMs when one processor is installed and up to 16x DIMMs
when two processors are installed. Each processor has four memory channels, and there are two DIMMs
per memory channel (2 DPC). RDIMMs are supported. UDIMMs and LR-DIMMs are not supported.
135 W processor limitation: If the E5-2690 v4 or E5-2698 v4 processors are selected, a maximum of
8 DIMMs can be installed per server (a maximum of 4 per processor).
The following table lists the memory options that are available for the sd350 server.

In the sd350, the maximum memory speed of a configuration is the lower of the following two values:
The memory speed of the processor
The memory speed of the DIMM
The following table shows the maximum memory speeds that are achievable. The table also shows the
maximum memory capacity at any speed that is supported by the DIMM and the maximum memory
capacity at the rated DIMM speed.
In the table, cells that are highlighted in gray indicate when the specific combination of DIMM voltage and
number of DIMMs per channel still allows the DIMMs to operate at the rated speed.
