Six green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 384GB (6x64GB) DDR5-6400 ECC RDIMM CL52 1.1V 2Rx4 memory upgrade for Supermicro H13SRH

SKU CH-PSX7-35BZ6

A 384 GB DDR5-6400 ECC registered server memory kit built with six 64 GB 2Rx4 modules at 1.1 V and CL52 latency, validated for the Supermicro H13SRH 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 maximum server density
  • DDR5-6400 speed with CL52 latency delivers rated throughput for Supermicro H13SRH
  • ECC and registered design correct single-bit errors and offload the memory controller
  • 1 V operation matches the board's voltage requirement for stable full-population use
  • 288-pin RDIMM form factor fits the exact slot type the motherboard expects

Exact-Match DDR5-6400 RDIMM Kit

This 384GB kit contains six 64GB DDR5-6400 ECC Registered DIMMs built to the exact rank, voltage and timing the Supermicro H13SRH memory controller expects. It is intended for administrators who must populate every slot at full capacity without compatibility guesswork.

DDR5 RDIMM Population Limits

DDR5 Registered DIMMs allow full-slot population because the register buffers the command bus, yet the motherboard still defines maximum capacity per slot and approved population order. The manual must be consulted before installation to confirm supported configurations.

Upgrade From Partial or Lower-Capacity Kits

Replacing a partially filled set or smaller RDIMMs with this 6x64GB kit raises total memory to 384GB at the board's rated 6400MT/s speed. The jump is worth it when workloads need the full capacity ceiling and ECC protection at native voltage.

Questions about this item

Should I pick the 384GB kit or a smaller capacity for my Supermicro H13SRH?

The 384GB kit (6 × 64GB) fills all six channels on the H13SRH, delivering maximum bandwidth and capacity; choose a smaller kit only if your workload does not need the full 384GB or if your CPU SKU limits total memory.

What does DDR5-6400 CL52 mean once the modules are installed in the server?

The memory controller will run the DIMMs at 6400 MT/s with a CAS latency of 52 cycles, giving a peak transfer rate of PC5-51200 while the registered buffer keeps every slot stable at full population.

Does the 288-pin RDIMM interface limit speed or capacity on the H13SRH?

The 288-pin registered DDR5 form factor is exactly what the H13SRH requires; it supports the full 6400 MT/s data rate and 64GB per module without down-clocking when all six slots are populated.
