64GB DDR4 RDIMM for Lenovo servers

This 64GB DDR4 3200 registered DIMM is built for Lenovo ThinkSystem servers running AMD processors. It targets administrators who need ECC-protected capacity in a single module for memory-intensive workloads such as virtualization or database hosting. The 2Rx4 organisation and CL22 timing suit registered server platforms that require registered signalling.

Registered 288-pin build with ECC

The module uses a standard 288-pin DDR4 RDIMM form factor without a heat spreader, relying on server chassis airflow for cooling. Registered buffering and on-die ECC reduce electrical load on the memory controller and correct single-bit errors, improving uptime in mission-critical deployments. Major OEM chips from Samsung, Micron or Hynix underpin the assembly.

Single-module upgrade simplicity

The package contains one 64GB stick, allowing capacity to be added in increments that match the server's slot population rules. No extra cables, brackets or configuration utilities are bundled; installation follows the system service manual. Compatibility is validated against Lenovo part 4X77A12189 for AMD-based ThinkSystem platforms.

Questions about this item

What speed does the DDR4 3200 PC4-25600 interface run at in a Lenovo ThinkSystem server?

The module operates at DDR4 3200 MT/s, which is the PC4-25600 data rate, when installed in a compatible Lenovo ThinkSystem server with AMD processors.

Will this 288-pin ECC RDIMM fit in a standard Lenovo ThinkSystem DIMM slot?

Yes, the 288-pin DDR4 RDIMM form factor matches the registered DIMM slots used in supported Lenovo ThinkSystem servers.

How do I install this 64GB 2Rx4 module, 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 retention clips lock, then verify in BIOS that the full 64 GB is recognised at 3200 MT/s with ECC active.
