Feature
code*
* For CTO configurations, the feature code represents a processor, and fans and heatsinks are derived by the configuration tool.
** Factory-installed only (CTO or Special Bid models); no field upgrade.
Configuration note: If processors with 200 W or 205 W TDP are used, the following conditions must be met:
No drive backplanes installed (M.2 drives are supported)
No rear HDD kit installed
No PCIe flash adapters installed
No GPUs installed
ASHRAE A2 (35°C [95 °F]) only; no fan failure support
Memory
The SR630 server supports up to 12 TruDDR4 memory DIMMs with one processor and up to 24 DIMMs when
two processors are installed. Each processor has six memory channels, and there are two DIMMs per channel.
Lenovo TruDDR4 memory uses the highest-quality components sourced from Tier 1 DRAM suppliers and only
memory that meets strict requirements is selected. It is compatibility tested and tuned on every ThinkSystem
server to maximize performance and reliability.
TruDDR4 memory has a unique signature programmed into the DIMM, which enables Lenovo servers to verify
whether the memory installed is qualified and supported. Lenovo qualified and supported TruDDR4 memory is
covered by Lenovo warranty, and service and support provided worldwide.
The following rules apply when selecting the memory configuration:
The server supports RDIMMs, LRDIMMs, or 3DS RDIMMs (support for 3DS RDIMMs is planned for future).
Mixing different types of memory (RDIMMs, LRDIMMs, and 3DS RDIMMs) is not supported.
Mixing x4 and x8 RDIMMs and RDIMMs of different capacity is supported.
All DIMMs in the server operate at the same speed up to 2666 MHz, which is determined by the maximum
memory speed supported by the specific processor.
Note: Maximum memory speed can be achieved when Max performance mode is enabled in UEFI.
The following maximum memory capacities supported by the server:
RDIMMs: 768 GB (384 GB per processor).
LRDIMMs: 1.5 TB (768 GB per processor).
3DS RDIMMs: 3 TB (1.5 GB per processor) (requires processors that support 1.5 TB of memory per
socket; support is planned for future).
The following memory protection technologies are supported:
ECC
SDDC (for x4-based memory DIMMs)
Memory mirroring
Memory rank sparing
Patrol scrubbing
Demand scrubbing
