Server-grade DDR5 ECC RDIMM kit

This 192GB kit delivers two 96GB registered DDR5 modules built for the Lenovo ThinkSystem ST650 V3 tower server. Error-correcting code and registered signalling protect data integrity in continuous workloads. The PC5-44800 rating confirms 5600 MT/s operation at the standard 1.1V DDR5 voltage. It targets administrators who need maximum supported capacity in a validated configuration.

288-pin registered modules without heat spreaders

Each stick uses a 2Rx4 organisation sourced from major OEM DRAM suppliers and fits the server's 288-pin DDR5 RDIMM slots directly. The absence of heat spreaders keeps the profile low for dense memory populations while the registered buffer reduces electrical load on the memory controller. Installation follows the server's documented DIMM population rules and requires no additional cabling or tools.

Upgrade from smaller RDIMM sets or non-ECC memory

Replacing lower-capacity registered kits with this 192GB configuration removes a memory ceiling that limits virtualisation density or in-memory databases. The jump is worth it when the workload demands full ECC protection and the platform's qualified vendor list includes this part number. Systems already running at the maximum supported DIMM count per channel cannot accept additional modules.

Questions about this item

What DDR5 speed and PC5 rating does this 192GB kit run at?

The kit operates at DDR5 5600 with a PC5-44800 data rate, the standard supported by the Lenovo ThinkSystem ST650 V3 memory controller.

What physical slot and pin count do these modules need?

Each 96GB module is a 288-pin DDR5 RDIMM that installs in the server's standard DDR5 DIMM slots; the 2Rx4 rank layout must match the platform's population rules.

How do I install the two modules correctly in the ST650 V3?

Power down the server, open the chassis, insert both RDIMMs into the matching channel slots indicated in the system manual until the ejector clips click, then close the chassis and power on.
