Two green DDR5 RDIMM modules without heat spreaders, 288-pin, 1Rx8, CL52, 1.1V

NEMIX RAM

NEMIX RAM DDR5 6400 32GB 2x16GB CL52 ECC RDIMM Supermicro H13DSH memory upgrade

SKU CH-7T40-7HHGQ

A 32GB kit of two 16GB DDR5 6400 RDIMM modules with ECC and registered buffering, validated for the Supermicro H13DSH motherboard

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Exact DDR5-6400 kit matches Supermicro H13DSH memory-controller specs for full-speed operation
  • 288-pin Registered ECC RDIMM form factor fits the board's required slot type and population rules
  • Registered buffering offloads the controller so every slot runs fully populated at rated capacity
  • On-die ECC corrects single-bit errors automatically preventing silent data corruption and unplanned downtime
  • Built with major-OEM Samsung Micron Hynix chips validated for enterprise server reliability

Exact-Match Upgrade Kit

This 32 GB kit contains two 16 GB DDR5 modules built to the precise rank, voltage and timing the server memory controller expects. It is intended for administrators upgrading a Supermicro H13DSH motherboard with registered ECC memory.

Registered Architecture Limits

Registered DIMMs buffer address and command signals so the controller can drive every populated slot at the rated 6400 MT/s without signal degradation. The 1.1 V operating voltage and CL52 latency are fixed by the DDR5 specification this board implements.

No Heat Spreader Daily Impact

The modules ship without a heat spreader, leaving the DRAM exposed for direct airflow from server chassis fans. Standard 288-pin RDIMM keying prevents accidental insertion of unbuffered or SODIMM modules during maintenance.

Questions about this item

Should I pick this 32 GB kit or a 64 GB kit for the H13DSH?

Choose this 32 GB kit if your workload fits within 32 GB; the H13DSH supports larger capacities, but only your application size and the manual’s population rules can tell you which total is right.

What does the 6400 MT/s rating actually deliver once the modules are seated in the H13DSH?

The board’s memory controller will run the kit at DDR5-6400 with CL52 timings at 1.1 V, giving the full rated bandwidth as long as the DIMMs are populated in the order the manual specifies.

How does the 288-pin RDIMM interface limit what I can install?

The H13DSH only accepts 288-pin Registered DIMMs; UDIMMs or SODIMMs will not fit electrically or mechanically, so this RDIMM form factor is mandatory for any upgrade.
