In addition, you can take advantage of a memory configurator tool, which is available at the following site:

Memory module selection
The following memory modules (DIMMs) are supported for use in the ThinkSystem SR950 server. See
static.lenovo.com/us/en/serverproven/index.shtml
for specific memory module part numbers and ordering
information.
A label on each DIMM identifies the DIMM type. This information is in the format
xxxxx
n
Rxxx PC4-xxxxx-
xx-xx-xxx
. Where
n
indicates if the DIMM is single-rank (n=1) or dual-rank (n=2).
Notes:
• Installing or removing DIMMs changes the server configuration. When you restart the server, it displays a
message that indicates that the memory configuration has changed. There are multiple ways to view the
server configuration. See “Management options” on page 19 for a description of each management
method and how each method applies to various deployment situations.
• When you replace a DIMM, the server provides automatic DIMM enablement capability without requiring
you to use the Lenovo XClarity Provisioning Manager to enable the new DIMM manually.
Memory architecture
The relationship between memory controllers, channels, and connectors on each system board is shown in
the following illustration and each memory channel has two DIMM slots (0, furthest from the processor, and
1, closest to the processor).
• Each processor in your server has two memory controllers: IMC1 and IMC2.
• Each memory controller has three memory channels:
– Processor 1:
– IMC1 has memory channels A, B, and C.
– IMC2 has memory channels D, E, and F.
– Processor 2:
– IMC1 has memory channels G, H, and J.
– IMC2 has memory channels K, L, and M.
• Each memory channel has two DIMM slots: slot 0 (furthest from the processor) and slot 1 (closest to the
processor).
