Server ECC registered upgrade

This 16GB DDR4 2933MHz RDIMM is built for Lenovo ThinkSystem SR530, SR550, SR570, SR590 and SR670 servers running Xeon SP Gen 2 processors. It delivers 288-pin ECC registered operation at 1.2V with CL21 latency for error-correcting stability in multi-socket workloads.

ECC registered behaviour

The module uses 2Rx8 registered buffering and on-die ECC to maintain data integrity across large memory arrays. It cannot be mixed with unbuffered DIMMs and will not function in standard desktop boards that lack registered memory support.

Suited for ThinkSystem SR servers

Ideal for administrators extending SR530, SR550, SR570, SR590 or SR670 capacity with validated OWC modules. Not suitable for desktop PCs, consumer workstations or any system requiring unbuffered non-ECC DDR4 memory.

Questions about this item

Will the 16GB DDR4 2933MHz ECC Registered RDIMM need any firmware updates or component replacements during its service life?

The module has no heat spreader and no moving parts, so no firmware updates or component replacements are required under normal server operation.

What limit appears first when the 2Rx8 Registered DIMM runs continuously at 2933MHz in a ThinkSystem SR670?

The registered buffer and ECC logic add one cycle of latency, so the memory controller's command queue fills before thermal or power limits are reached.

How much heat and power does the 1.2V 288-pin RDIMM produce when installed in a Lenovo SR590 running 24/7?

At 1.2V the module draws minimal power and, without a heat spreader, relies on chassis airflow; typical server cooling keeps temperatures well within JEDEC limits.
