Compatible Lenovo DDR5 RDIMM

This 64GB registered DDR5 module is built for Lenovo ThinkSystem servers with Intel processors. It carries ECC and registered signalling for data integrity in multi-socket platforms. The single stick installs in a standard 288-pin slot and runs at the JEDEC 5600 MT/s rate. No heat spreader is fitted.

Suited for registered ECC slots only

IT teams expanding memory in qualified Lenovo servers will find the correct electrical and mechanical match here. Builders using consumer motherboards, laptops or non-ECC workstations cannot use this module because the registered buffer and ECC logic are not supported. Systems requiring unbuffered DIMMs or lower densities should look elsewhere.

5600 MT/s DDR5 speed rating

The module operates at the PC5-44800 data rate with CL46 latency at 1.10V. This speed figure determines whether the memory matches the server memory controller specification and the populated channel configuration. Verify the platform Qualified Vendor List for 5600 MT/s registered DIMM support before purchase.

Questions about this item

Does this 288-pin DDR5 RDIMM need a Lenovo ThinkSystem server with an Intel processor to operate?

Yes, the module is validated for Lenovo ThinkSystem servers using Intel processors and requires a DDR5 RDIMM slot that supports ECC registered memory.

Can I mix this 5600MHz CL46 2Rx4 module with slower DDR5 RDIMMs already installed in the same server?

The server will run all modules at the speed of the slowest installed kit, so 5600MHz modules will down-clock to match older DDR5 RDIMMs.

How can I confirm the 64GB stick is detected at 5600MHz with ECC active after installation?

Check the system BIOS or UEFI memory information screen; it should show 64GB, 5600MHz, CL46, ECC enabled, and registered operation.
