Exact-match DDR5-6400 kit

This 128GB kit contains two 64GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.10V operation. Registered ECC architecture with 4Rx4 organisation targets the Supermicro X14SDW-64C-SP9F motherboard. It is built for servers that require registered modules and on-die error correction.

DDR5 slot population rules

The motherboard dictates how many registered DIMMs it accepts per channel and in which order they must be installed. Filling every slot at the rated 6400 speed depends on the platform's memory controller and BIOS revision. Exceeding the approved configuration forces the system to down-clock or fail to boot.

4Rx4 registered ECC specification

The 4Rx4 registered ECC layout is the single attribute the memory controller checks before enabling full capacity at 6400 MT/s. A different rank count, unbuffered design, or missing ECC will prevent the kit from operating as intended. Buyers who need unbuffered UDIMMs or non-ECC memory cannot use this kit.

Questions sur cet article

Is the 128GB 2x64GB kit the only capacity option for this NEMIX RAM MR51200-944K2?

Yes, this part number is offered only as a 128GB kit containing two 64GB modules.

What does the DDR5 6400 speed rating mean once the modules are installed in a Supermicro X14SDW-64C-SP9F?

The memory controller will recognise the kit at its rated 6400 MT/s, delivering PC5-51200 bandwidth with CL52 latency at 1.10V.

How does the 288-pin RDIMM interface and registered ECC design affect real-world operation?

The registered buffer reduces electrical load so all slots can run fully populated, while ECC corrects single-bit errors to prevent silent data corruption.
