Two green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 64GB (2×32GB) DDR5 6400 CL52 1.1V 2Rx8 ECC RDIMM Supermicro H13SVW-N

SKU CH-X7QJ-8QXRZ

A 64 GB DDR5 registered ECC memory kit with two 32 GB modules at 6400 MT/s, CL52, 1.1 V, 2Rx8, validated for the Supermicro H13SVW-N motherboard

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 64 GB total capacity from two 32 GB modules for full server population
  • DDR5-6400 speed with CL52 latency runs at rated frequency on the Supermicro H13SVW-N
  • 10 V registered ECC RDIMM offloads the memory controller and corrects single-bit errors
  • 2Rx8 dual-rank organization matches the motherboard's population rules for stable operation
  • 288-pin RDIMM form factor fits the exact slot type required by the H13SVW-N

Supermicro H13SVW-N DDR5 RDIMM Kit

This 64GB kit contains two 32GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SVW-N memory controller expects. Registered ECC architecture with 2Rx8 organisation and CL52 latency ensures the modules are recognised at full capacity and run at their rated speed.

DDR5 6400 Registered ECC Constraints

The 288-pin RDIMM form factor fits only boards wired for registered memory; UDIMM or SODIMM slots will not accept it. Population rules on the H13SVW-N dictate which slots must be filled first, so the manual must be consulted before installation.

Upgrade From Lower Capacity Or Non-ECC

Replaces smaller DDR5 RDIMM kits or non-ECC modules that leave slots empty or expose data to silent corruption. The jump is worthwhile when the workload demands full registered ECC stability at 6400 MT/s across every populated channel.

Questions about this item

Should I pick the 2×32 GB kit or a single 64 GB module?

The kit is a matched pair of two 32 GB modules tested together for dual-channel operation on the Supermicro H13SVW-N. A single 64 GB module would leave one channel empty and halve memory bandwidth.

What does the 6400 MT/s rating mean once installed?

The modules run at 6400 MT/s (PC5-51200) with CL52 latency at 1.10 V. The registered design lets all slots run at this speed when fully populated, and ECC corrects single-bit errors in real time.

Is this standard DDR5 or does it need a special slot?

It uses the 288-pin DDR5 RDIMM form factor required by the Supermicro H13SVW-N. The registered interface is mandatory for this board; standard UDIMMs will not fit or function.
