Server-grade DDR5 upgrade kit

This 256 GB kit supplies two 128 GB DDR5 4800 CL40 registered ECC RDIMMs built for Lenovo ThinkSystem SD650 V3, SD650-I V3, SD665 V3, SD665-N V3 and SR630 V3 servers. It targets IT teams expanding memory capacity in compatible rack or dense-compute platforms.

288-pin registered ECC modules

Each stick uses a 4Rx4 organisation at 1.1 V with no heat spreader, fitting standard DDR5 RDIMM slots in the listed systems. The registered buffer and on-die ECC maintain data integrity under sustained workloads but prevent use in consumer desktops or alongside unbuffered or load-reduced DIMMs.

JEDEC-compliant matched pair

The two modules are tested together to meet JEDEC and RoHS standards, delivering a warranty-safe upgrade that preserves the server’s original firmware validation. No extra cables, brackets or software licences are included in the package.

Questions sur cet article

What DDR5 speed does the PC5-38400 rating actually run at?

The kit runs at DDR5 4800, which is the JEDEC-standard speed for the PC5-38400 designation.

What physical slot and clearance does a 288-pin 4Rx4 RDIMM need?

It fits a standard 288-pin DDR5 DIMM slot; the modules have no heat spreader, so they fit in tight 1U server bays.

What is the correct order for populating the two 128 GB modules in a ThinkSystem SR630 V3?

Install one module per processor socket, using the first channel slot indicated in the server's memory population guide.
