NEMIX RAM 128GB DDR5 6400 CL52 2Rx4 1.1V ECC Registered RDIMM memory upgrade

SKU CH-VYBZ-Z9PE4

128 GB DDR5 6400 CL52 2Rx4 1.1 V ECC registered RDIMM built for Supermicro H14DSH motherboards

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes
  • 128 GB capacity lets you populate every slot on the Supermicro H14DSH
  • DDR5-6400 speed with CL52 timing runs at the rated frequency your board expects
  • Registered ECC architecture offloads the controller and corrects single-bit errors on the fly
  • 1 V operation matches the motherboard voltage requirement for stable full-load performance
  • 288-pin RDIMM form factor fits the H14DSH memory slots without adapters or mismatches

Capacity & Purpose

This 128GB DDR5-6400 RDIMM is built for servers that require registered ECC memory. The 2Rx4 organization and CL52 latency match the memory controller expectations of the Supermicro H14DSH motherboard. It targets administrators upgrading capacity without changing the platform.

Build Integration

The 288-pin registered form factor fits only boards wired for RDIMM slots, not UDIMM or SODIMM layouts. Registered buffering reduces electrical load on the controller so every populated slot can run at the rated 6400 MT/s speed. ECC corrects single-bit errors before they reach the operating system.

Sustained Operation

Operating at 1.10V, the modules maintain stability across fully populated channels during continuous workloads. Registered architecture prevents signal degradation that can appear when all slots are filled. The exact rank, voltage, and timing combination keeps the memory controller from down-clocking under prolonged stress.

Questions about this item

Will the CL52 latency hold under sustained server workloads?

The CAS latency is rated at CL52 at 6400 MT/s and the registered architecture maintains signal integrity across all populated slots, so the timing stays consistent under load.

How much heat and power does a 128 GB DDR5 6400 registered DIMM draw running 24/7?

Operating at 1.1 V, the module runs cool without a heat spreader; registered buffering reduces controller load, keeping power draw low during continuous operation.

Does my Supermicro H14DSH need a specific BIOS version or CPU to accept this 2Rx4 RDIMM?

The DIMM is validated for the H14DSH motherboard; consult your system manual for the approved population order and any firmware requirements before installing.
