NEMIX RAM MR51200-324K4 128GB (4x32GB) DDR5-6400 CL52 2Rx4 ECC RDIMM Supermicro X14QBH+

Exact-match DDR5-6400 kit for Supermicro X14QBH+

This 128 GB kit contains four 32 GB DDR5-6400 registered ECC RDIMMs rated at CL52 and 1.10 V. The 2Rx4 organisation matches the memory controller expectations of the Supermicro X14QBH+ motherboard so the full capacity is recognised at rated speed. It is built for servers that require registered DDR5 with on-die ECC. Buyers needing unbuffered UDIMMs or SODIMMs cannot use this kit.

Check your server manual before ordering

Verify the motherboard manual for approved DIMM population order, maximum capacity per channel and any BIOS version requirements. The kit uses 288-pin registered RDIMMs; the board must support registered modules and the specific 2Rx4 rank configuration. Confirm that all four slots can be populated simultaneously at DDR5-6400. Systems limited to UDIMMs or lower speeds will not accept this memory.

Thermals noise and power in normal use

Registered DDR5 modules at 1.10 V draw modest power per DIMM and run without heat spreaders in standard server airflow. The RDIMM buffer reduces electrical load on the memory controller, helping stability when all four slots are filled. In a properly cooled chassis the modules operate silently with no active cooling of their own. Ensure case airflow meets the server vendor's thermal guidelines for fully populated memory banks.
