NEMIX RAM 64GB DDR5 6400 CL52 2Rx4 1.1V ECC RDIMM Supermicro H13DSH memory upgrade

SKU CH-1Z5Q-AK22J

64 GB DDR5 6400 CL52 2Rx4 1.1 V ECC registered RDIMM built for the Supermicro H13DSH

  • Total capacity64 GB
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 64 GB DDR5-6400 capacity lets the Supermicro H13DSH run fully populated at rated speed
  • CL52 timing and 1.1 V voltage match the board's memory-controller expectations for stable operation
  • Registered ECC 2Rx4 architecture offloads the controller and corrects single-bit errors to prevent silent data corruption
  • 288-pin RDIMM form factor fits the H13DSH DIMM slots exactly, not UDIMM or SODIMM
  • Lifetime replacement warranty with US-based technical support backs the upgrade for the server's service life

Exact-match DDR5 upgrade for Supermicro H13DSH

This 64 GB DDR5 6400 module delivers the precise 2Rx4 registered ECC configuration the H13DSH memory controller expects. The 1.10 V operating voltage and CL52 timing match the board's validated population rules so the full capacity is recognised at rated speed. Builders expanding a compatible Supermicro server avoid the trial-and-error of generic DIMMs.

Thermals noise and power draw in normal use

Registered buffering reduces electrical load on the memory controller, allowing every slot to run fully populated without extra voltage. The 1.10 V DDR5 baseline keeps power draw low compared with higher-voltage alternatives. No heat spreader is fitted, so airflow through the chassis determines module temperature under sustained workloads.

What the bundled accessories

The package contains only the 288-pin RDIMM itself; no cables, brackets or configuration utilities are included. Installation follows the motherboard manual's approved DIMM population order. Lifetime replacement coverage and US-based technical support provide a fallback if a module fails verification after deployment.

Questions about this item

How do I install this 288-pin RDIMM into the Supermicro H13DSH, and which population rule is most often missed?

Insert the module into the correct DDR5 slot following the motherboard manual's population sequence for 2Rx4 registered DIMMs; the step most often missed is matching the exact slot order required for full 64GB recognition at 6400 speed.

What maintenance or replacement will this 1.1V ECC RDIMM need during its service life?

No scheduled maintenance is required; the module is designed for continuous server operation with on-die ECC correcting single-bit errors, and replacement only occurs if a hardware fault is detected.

What limit appears first when this CL52 6400 DDR5 runs fully populated under sustained load?

The CAS latency of 52 cycles at 6400 MT/s sets the timing boundary; sustained throughput is constrained by this latency figure before thermal or voltage limits are reached.
