Server memory upgrade

This is a 64GB DDR4 2933MHz ECC registered RDIMM designed for Lenovo ThinkSystem servers with Xeon SP Gen 2 processors. It operates at 1.2V with CL21 latency and uses a 288-pin form factor. The module is built to JEDEC standards and replaces Lenovo part numbers 4X70V98063, 4ZC7A08710 and 4ZC7A08744.

Suited for ThinkSystem SR530, SR550, SR570.

This memory fits the listed Lenovo ThinkSystem models and other compatible server, workstation or NAS platforms that accept DDR4 ECC registered DIMMs. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers who need non-ECC or unbuffered memory for a consumer motherboard should look elsewhere.

Verify your system requirements

Confirm that your server supports DDR4 ECC registered RDIMMs and has available 288-pin slots. The module runs at 2933MHz and is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds. Check the maximum capacity per slot and total memory limit for your specific ThinkSystem model before ordering.

Preguntas sobre este artículo

Does my Lenovo ThinkSystem SR670 already need registered ECC DDR4 slots to accept this 288-pin RDIMM?

Yes. The module is a 288-pin DDR4 ECC Registered RDIMM and requires a server or workstation platform with registered memory slots. It will not work in standard desktop boards that use unbuffered memory.

Can I add this PC4-23400 CL21 module alongside existing 2666 MHz registered ECC DIMMs in my SR590?

The module is backward compatible with 2666 MHz, 2400 MHz and 2133 MHz speeds. When mixed, all DIMMs will run at the speed of the slowest installed module.

How can I confirm the 64 GB module is detected at 2933 MHz with ECC active after installation?

Check the system BIOS or UEFI memory configuration screen; it should show 64 GB per DIMM, 2933 MT/s (PC4-23400) and ECC Registered status.
