NEMIX RAM 32GB DDR5 5600 ECC RDIMM

This 32GB DDR5 module runs at 5600MHz with CL46 latency and 1.10V operation. It is a registered ECC RDIMM built for Lenovo ThinkSystem servers using Intel processors. The 1Rx4 configuration uses major OEM chips from Samsung, Micron or Hynix. No heat spreader is included on the 288-pin module.

Suited for Lenovo ThinkSystem servers needing

This module targets administrators upgrading or repairing compatible Lenovo Intel-based platforms. It is not for systems that require unbuffered UDIMMs or non-ECC memory. Buyers who need a different capacity, speed or rank configuration should verify their platform requirements before purchase.

Simple installation in compatible server DIMM slots

The RDIMM installs like standard server memory by aligning the key notch and pressing firmly until the retention clips engage. Common issues include mixing registered and unbuffered modules or populating slots in an unsupported order. Always consult the system service manual for the correct population sequence.

Questions about this item

Will this 288-pin DDR5 RDIMM fit my Lenovo ThinkSystem server that takes the 4X77A88049 part number?

Yes — this module is built to the 4X77A88049 specification, so it installs directly into the matching Lenovo ThinkSystem memory slots.

Can I add this 1Rx4 CL46 ECC registered stick to a channel that already has slower DDR5 RDIMMs?

The server will run all modules at the speed and timing of the slowest installed DIMM; mixing ranks or latencies is supported but reduces overall bandwidth.

How do I confirm the 32 GB stick is running at 5600 MT/s with ECC active after installation?

Check the system BIOS or UEFI memory information screen — it should report 5600 MT/s, CL46, 1.10 V and ECC enabled for the new module.
