Server-grade DDR5 memory upgrade

This 32 GB DDR5-6400 registered ECC RDIMM is built for Supermicro H13SRH motherboards. It delivers 32 GB of capacity at 6400 MT/s with CL52 latency and 1.1 V operation. The 2Rx8 dual-rank organisation and registered architecture let the memory controller drive fully populated channels without signal degradation. Major OEM Samsung Micron or Hynix chips provide enterprise-grade reliability.

Buyers needing registered ECC for a Supermicro

This module suits administrators who must match the exact rank voltage and timing their board expects. It is not for systems that accept only unbuffered UDIMMs or SODIMMs. It is not for platforms limited to lower DDR5 speeds or different pin counts. Builders without a Supermicro H13SRH should verify their motherboard manual before purchasing.

288-pin DDR5 RDIMM form factor

The 288-pin registered DIMM is the single physical and electrical interface that decides fitment. Only motherboards wired for DDR5 RDIMMs can accept this module. UDIMM or SODIMM slots will not work. Confirm your board requires a 288-pin RDIMM before ordering.

Questions about this item

What comes in the box and what must I source separately for this 32 GB DDR5 6400 CL52 RDIMM?

The package contains one 32 GB 288-pin DDR5 6400 CL52 2Rx8 1.1 V ECC Registered RDIMM. No cables, brackets or additional modules are included; buy matching sticks separately if your board requires a multi-DIMM population.

Should I choose a different capacity or speed version of this NEMIX RAM DDR5 RDIMM for my Supermicro H13SRH?

This module is a 32 GB DDR5 6400 CL52 2Rx8 1.1 V Registered ECC RDIMM. Select a different capacity or speed only if your motherboard manual lists it as supported; otherwise this exact specification matches the board's validated configuration.

What does the 6400 MT/s rating mean once this RDIMM is installed in a Supermicro H13SRH system?

The 6400 MT/s (PC5-51200) rating indicates the maximum data rate the memory controller can run this 2Rx8 Registered ECC module at, provided the BIOS is set to the rated speed and the board's population rules are followed.
