Six green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 384GB (6×64GB) DDR5 6400 CL52 1.1V ECC RDIMM Supermicro H13SST-G memory upgrade

SKU CH-W54C-Z5WMA

384 GB kit of six 64 GB DDR5 RDIMMs running at 6400 MT/s with CL52 latency, 1.1 V registered ECC, validated for the Supermicro H13SST-G motherboard

  • Total capacity384 GB (6 × 64 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 384 GB total capacity from six 64 GB modules for dense server workloads
  • DDR5 6400 (PC5-51200) speed matching the board's rated frequency
  • CL52 latency and 1.10 V operation tuned to the memory controller
  • Registered ECC RDIMM with 2Rx4 organisation offloads the controller and corrects single-bit errors
  • 288-pin form factor verified for Supermicro H13SST-G motherboard compatibility

Exact-match DDR5 upgrade kit

This 384GB kit contains six 64GB DDR5 6400 CL52 registered ECC RDIMMs built to the voltage and rank layout the Supermicro H13SST-G memory controller expects. Each module runs at 1.1V with 2Rx4 organization so the board recognizes the full capacity at rated speed. The 288-pin form factor matches the slots on that motherboard.

Replaces partial or slower memory sets

Install this kit when the server currently runs fewer than six DIMMs or operates at a lower data rate than PC5-51200. The registered architecture lets every slot stay populated at full capacity without overloading the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption. Skip this kit if the platform cannot accept 2Rx4 registered modules or if the manual limits total capacity below 384GB.

Fits Supermicro H13SST-G memory rules

The modules slot directly into the board’s 288-pin RDIMM sockets following the population order in the system manual. No heat spreaders are fitted so clearance stays minimal inside dense chassis. Registered buffering frees the memory controller for other tasks while ECC protects production workloads. Verify the approved DIMM sequence and maximum supported capacity before installation.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SST-G DIMM slots?

Yes, the kit uses the exact 288-pin Registered RDIMM form factor required by the H13SST-G motherboard; it is not a UDIMM or SODIMM and matches the board's physical slot keying.

What population order should I follow when installing the six 64 GB modules on the H13SST-G?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first to reach the full 384 GB capacity at DDR5-6400.

Do these modules need active cooling or periodic cleaning because they lack a heat spreader?

The DIMMs ship without a heat spreader and rely on the server's chassis airflow; ensure case fans maintain adequate flow over the modules and dust them during routine system maintenance.
