Four green DDR5 RDIMM modules with black chips, no heat spreaders

NEMIX RAM

NEMIX RAM DDR5 6400 ECC RDIMM 384GB 4x96GB CL52 1.1V Supermicro X14SDV-42C-SP3F

SKU CH-ZEXM-J4JD0

384 GB DDR5-6400 ECC registered server memory kit, four 96 GB modules at CL52 and 1.1 V, validated for the Supermicro X14SDV-42C-SP3F motherboard

  • Total capacity384 GB (4 × 96 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 384GB 4X96GB

  • 384 GB total capacity from four 96 GB modules for maximum server density
  • DDR5 6400 speed with CL52 latency delivers rated throughput on Supermicro X14SDV-42C-SP3F
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operation matches the motherboard's memory-controller requirements exactly
  • 288-pin RDIMM form factor ensures physical and electrical compatibility with the target platform

Exact-fit DDR5 ECC RDIMM kit

This 384 GB kit contains four 96 GB DDR5 6400 Registered ECC modules built to the precise rank, voltage and timing the Supermicro X14SDV-42C-SP3F memory controller expects. The 2Rx4 organization and 1.10 V operation let the board recognise full capacity and run at rated speed without manual tuning.

Registered buffering and ECC protection

Registered architecture offloads the memory controller so every slot stays stable when fully populated, while on-die ECC catches and corrects single-bit errors before they reach production workloads. The modules ship without heat spreaders, matching the board's standard airflow design.

384 GB headroom for dense workloads

Four 96 GB RDIMMs fill the board's supported slots and deliver maximum registered-DIMM capacity for virtualisation, database caching or large-dataset analytics. Systems that need more memory than the board's registered-DIMM limit or that require unbuffered UDIMMs cannot use this kit.

Questions about this item

Will the 96 GB DDR5 RDIMM modules need replacement if I later populate all 14 slots on the Supermicro X14SDV-42C-SP3F?

The kit uses 2Rx4 registered ECC DDR5 at 1.1 V, which is the exact rank and voltage the board expects for full-slot population; no module swap is required.

What limit appears first when the 384 GB kit runs at DDR5-6400 CL52 continuously?

The memory controller’s maximum supported speed and rank-per-channel ceiling are reached before thermal or power limits, so sustained throughput tops out at the rated 6400 MT/s.

How much heat and noise do the four 96 GB sticks produce under all-day load?

Bare 288-pin RDIMMs without heat spreaders rely on chassis airflow; at 1.1 V typical power stays within JEDEC limits, adding minimal heat and zero acoustic noise.
