Learn more about Lenovo ThinkServer RD350 memory

What Lenovo ThinkServer RD350 DIMM type is supported?

LRDIMM and RDIMM

Why are there various DIMM types supported?

Factory configured RD350 systems often have smaller, less expensive modules. As more memory is required different density and technologies are needed. DIMM type mixing is never recommended.

What is a registered memory module?

Registered DIMM memory modules have a register component between the DRAM modules and the motherboard memory controller. When manufactured as a dual in-line memory module (DIMM), a registered memory module is called an RDIMM.

What is a load reduced memory module?

Load reduced memory module technology uses a distributed data buffer to improve bandwidth efficiencies when scaling to higher capacities and speed on enterprise server systems. All LRDIMMs are registered but not all RDIMMs are LRDIMMs. LRDIMM or load-reduced DIMMs are (used in enterprise servers) support highest density modules and contain a memory buffer (MB) component usually made by IDT or Montage. The memory buffer minimizes the load on the server memory bus. LRDIMMs are commonly used to maximize Lenovo ThinkServer RD350.

What Lenovo ThinkServer RD350 memory speed is supported?

DDR4-2133, DDR4-2400 and DDR4-2666

Why may there be various speeds of Lenovo ThinkServer RD350 memory?

Some servers often have various configurations and versions. If you are unsure what you need, please refer to your RD350 manual or data sheet. If you need tech support, please contact us.

General DIMM population guideline for Lenovo ThinkServer RD350 upgrade to consider.

Some may or may not apply.

• Do not mix DIMM LRDIMM and RDIMM types.
• If mixing memory speeds, all 8 DIMMs run at the lowest DDR4-2133 bus frequency.
• Install DIMMs starting furthest from the processor.
• Do not install DIMMs if the corresponding processor is not installed.
• If only one processor is installed in a two CPU system, only half of the DIMM slots are available.
• To maximize performance, balance the total memory capacity between all installed processors.
• It is not required, but it is recommended to load the channels similarly if possible.
