Lenovo 02JK971 Compatible 64GB DDR4 RDIMM

This registered ECC module is built for Lenovo servers and workstations that require DDR4 3200 memory. It suits administrators upgrading a single slot in a supported platform. Buyers needing non-ECC unbuffered DIMMs or a different pin count cannot use this product.

Single Rank 2Rx4 64GB at 3200 MT/s CL22

The module delivers 64GB capacity in one 288-pin stick running at 1.20V with CL22 latency. It handles large datasets and virtualization workloads within the rated speed. Systems requiring higher frequencies, lower latencies, or multiple ranks per channel will exceed what this module provides.

No Heat Spreader Included in Package

The box contains only the 1x64GB DDR4 3200 PC4-25600 2Rx4 1.2V CL22 288-pin ECC RDIMM. There are no additional cooling accessories, cables, or software utilities supplied. Installers who need thermal management must source a separate solution.

Questions about this item

Will this DDR4 3200 CL22 ECC RDIMM run alongside my existing DDR4 modules in the same Lenovo server?

The module is a 64GB 2Rx4 DDR4 3200 CL22 registered DIMM at 1.20V; mixing speeds will cause the system to run all memory at the slowest installed speed and matching rank organisation is recommended.

How can I confirm the 64GB 2Rx4 ECC RDIMM is operating correctly after installation?

Check the BIOS or UEFI memory summary to verify 64GB detected, ECC enabled, speed shown as 3200 MT/s and CL22 timings applied.

What is included with the MR25600-924K1 module and what must be sourced separately?

The package contains one 64GB 288-pin DDR4 3200 CL22 ECC RDIMM; no heat spreader, cables, tools or additional memory are included.
