Lenovo ThinkSystem DDR5 ECC RDIMM

This 64GB registered DDR5 module is built for Lenovo ThinkSystem servers running Intel processors. It targets administrators who need error-correcting memory to maintain data integrity in production workloads.

288-pin registered design with 1.1V operation

The RDIMM form factor plugs directly into compatible server motherboards without a heat spreader, keeping the profile low for dense chassis layouts. ECC and registered buffering reduce electrical load on the memory controller during sustained use.

Replaces non-ECC or lower-capacity DIMMs

Upgrading from unbuffered or smaller modules adds error correction and doubles density per slot, which matters when virtualisation or database workloads exceed the current memory ceiling.

Questions about this item

What speed does the DDR5 4800 interface actually run at in a Lenovo ThinkSystem server?

The module operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, so that is the effective data rate once installed in a compatible ThinkSystem platform.

Does the 288-pin RDIMM fit the memory slots in a Lenovo ThinkSystem 4X77A77032 server?

Yes, the 288-pin DDR5 RDIMM form factor matches the registered DIMM slots used in the ThinkSystem 4X77A77032 and other Intel-based Lenovo servers listed for this part.

How is the module installed and what step is often missed?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both ejector clips click shut, then verify in BIOS that the 64 GB module is recognised at 4800 MT/s with ECC active.
