128 GB DDR4 3200 ECC RDIMM

This NEMIX RAM module delivers 128 GB of DDR4 3200 memory in a single 288-pin registered DIMM. It operates at 1.2 V with CL22 latency and uses a 4Rx4 organisation built from major OEM DRAM. The stick is validated for Lenovo ThinkSystem servers using AMD processors and carries part number MR25600-744K1.

Suited for Lenovo AMD servers only

Administrators expanding Lenovo ThinkSystem platforms that require DDR4 3200 registered ECC memory can install this module directly. Builders working with Intel-based servers, consumer motherboards, or systems that need unbuffered DIMMs or a different speed grade should look elsewhere.

4Rx4 rank configuration decides fit

The 4Rx4 organisation determines whether the server memory controller can address the full 128 GB capacity. Systems limited to dual-rank or single-rank modules will not recognise this DIMM, so verify the platform rank support before ordering.

Questions sur cet article

Does my Lenovo ThinkSystem server need to run AMD processors for this 4ZC7A15125-compatible 128 GB DDR4 3200 ECC RDIMM to work?

The module is validated for AMD-processor-based Lenovo ThinkSystem servers carrying part number 4ZC7A15125; it will not function in Intel-based models.

Can I mix this 4Rx4 1.2 V CL22 registered DIMM with existing 2Rx4 or 2Rx8 DDR4 3200 modules in the same channel?

Mixing different rank architectures (4Rx4 with 2Rx4/2Rx8) in the same channel is not supported; populate identical modules per channel for stable operation.

After installation, how do I confirm the single 128 GB 288-pin RDIMM is running at PC4-25600 with ECC active?

Enter the server BIOS or UEFI and verify the memory speed reads 3200 MT/s, capacity shows 128 GB, and ECC status reports enabled or active.
