32 GB DDR5 4800 registered ECC module

This single 32 GB DDR5 4800 RDIMM delivers error-correcting registered memory for Lenovo ThinkSystem servers built on Intel platforms. It runs at 1.1 V with a CL40 latency and uses a 2Rx8 organisation based on major OEM DRAM chips. The 288-pin form factor matches the memory slots qualified for the 4X77A77031 part number.

IT teams upgrading compatible ThinkSystem servers

The module suits administrators adding capacity to qualified Lenovo Intel-based servers that require registered ECC DDR5 at 4800 MT/s. It is not intended for workstations or desktops that accept only unbuffered UDIMMs, nor for systems limited to lower DDR5 speeds or different pin counts. Builders needing non-ECC memory or a different voltage should look elsewhere.

CL40 latency at 4800 MT/s

The CAS latency of CL40 at the rated 4800 MT/s speed is the key timing parameter that determines whether this RDIMM matches the server memory controller requirements. Verify the platform specification calls for CL40 before installation.

Questions sur cet article

Does the 288-pin DDR5 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR5 RDIMM form factor matches the standard registered DIMM slot used in compatible Lenovo ThinkSystem servers.

What is the correct seating procedure for this 2Rx8 registered module?

Align the notch on the module with the key in the slot, press down firmly until both retention clips click into place, and verify the module sits evenly.

Will the Samsung, Micron or Hynix chips on this module require any firmware updates over time?

The memory chips themselves do not require firmware updates; any related updates would come from the server BIOS or management controller.
