NEMIX RAM

NEMIX RAM 32GB DDR5 6400 CL52 2Rx8 ECC RDIMM Supermicro H13DSG-OM memory upgrade

SKU CH-B9E1-QCCDD

32 GB DDR5-6400 ECC registered RDIMM validated for the Supermicro H13DSG-OM motherboard

  • Total capacity32 GB
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 32 GB capacity lets you run larger workloads without swapping
  • DDR5 6400 speed feeds data to the CPU at the rated 6400 MT/s
  • CL52 latency keeps response tight for latency-sensitive server tasks
  • ECC and registered design corrects single-bit errors and offloads the memory controller
  • 288-pin RDIMM form factor matches the Supermicro H13DSG-OM slot exactly

System-Specific DDR5 RDIMM

This 32 GB DDR5 6400 registered ECC module is built for the Supermicro H13DSG-OM motherboard. It delivers the exact 2Rx8 rank structure, 1.1 V operating voltage and CL52 timing the platform expects.

Compatibility Verification

Confirm your motherboard manual for approved DIMM population order, maximum capacity per slot and any BIOS version requirements before ordering. The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function.

Thermals and Power

Operating at the standard 1.1 V, the module runs within typical server power envelopes without a heat spreader. Registered buffering reduces electrical load on the memory controller, aiding stability in fully populated configurations under sustained workloads.

Questions about this item

Does the 32GB DDR5 6400 kit include a heat spreader or do I need to buy one separately?

The module ships without a heat spreader, so the bare PCB is what you install. No extra cooling parts are required for normal server airflow.

Should I choose the 2Rx8 CL52 version or look for a different rank and latency for the Supermicro H13DSG-OM?

The board's memory controller expects 2Rx8 registered ECC at CL52 and 1.10V. Matching those exact parameters ensures full-speed operation without down-clocking.

Will the rated 6400 MT/s speed actually run at 6400 once the RDIMM is seated in the H13DSG-OM?

Yes. The DIMM is spec-matched to the motherboard's qualified-vendor list, so the memory controller will initialise it at DDR5-6400 with the stated CL52 timings.
