96 GB DDR5 5600 ECC RDIMM for Lenovo SR655 V3

This single 96 GB module delivers DDR5 5600 performance with ECC protection and registered buffering. It is built for the Lenovo ThinkSystem SR655 V3 AI Server and suits administrators expanding memory capacity in that platform. The 2Rx4 organisation and CL46 latency match the server’s qualified memory list.

Fits 288-pin DDR5 RDIMM slots at 1.1 V

The module plugs directly into the server’s registered DIMM sockets and operates at the standard 1.1 V DDR5 voltage. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis fans. ECC and register logic reduce electrical load on the memory controller, freeing signal integrity headroom for dense configurations.

Suits SR655 V3 upgrades needing maximum density

Ideal for IT teams populating every slot with 96 GB to reach the platform’s highest supported capacity. Not for systems that require unbuffered UDIMMs, non-ECC modules, lower-density sticks, or a different DDR generation. Buyers whose servers demand a qualified vendor part number should verify the MR44800-9624K1 code against their maintenance manual.

Questions about this item

How does the CL46 latency affect throughput during long compute jobs?

The module runs at DDR5 5600 with CL46 timing, so sustained bandwidth is limited by the 46-cycle CAS latency under continuous load.

What thermal or power behaviour should be expected when the DIMM runs 24/7?

Operating at 1.10 V without a heat spreader, the registered ECC RDIMM draws minimal power and relies on server chassis airflow for cooling.

Which server platform must already be installed for this memory to function?

It is validated for the Lenovo ThinkSystem SR655 V3 AI Server and requires that platform’s DDR5 RDIMM slots.
