Lenovo Server RDIMM Upgrade

This 32GB DDR4 2933 registered module is built for Lenovo server and workstation platforms that require ECC RDIMM memory. It installs as a single 288-pin DIMM and operates at 1.2V with CL21 latency.

Suited for ECC Registered Slots

It fits systems that accept 2Rx4 registered DDR4 RDIMMs and will not work in boards limited to unbuffered UDIMMs or non-ECC memory. Buyers needing consumer desktop RAM or SODIMM form factors should choose a different product.

Registered ECC with 2Rx4 Organisation

The module uses a 2Rx4 rank configuration with on-board ECC and registered buffering, which is the decisive attribute for compatibility with the target Lenovo server platforms.

Questions about this item

How much power does the 1.2 V DDR4 module draw when the server runs continuously?

The module operates at 1.2 V, the standard voltage for DDR4, keeping power draw low during all-day workloads.

What motherboard slot and firmware support are required for this 288-pin ECC RDIMM?

A server or workstation board with 288-pin DDR4 RDIMM slots and BIOS support for registered ECC memory is needed.

Will this 2Rx4 registered stick work alongside older 1Rx8 DDR4 modules in the same Lenovo system?

Mixing ranks is possible if the platform supports it, but matched kits are recommended for stability.
