Four green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM DDR5 6400 384GB 4x96GB CL52 1.1V ECC RDIMM Supermicro X14SDV-36C-SP3F memory upgrade

SKU CH-8XK5-7KMP4

384 GB DDR5-6400 ECC registered RDIMM kit (4 × 96 GB, CL52, 1.1 V) validated for the Supermicro X14SDV-36C-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 the Supermicro X14SDV-36C-SP3F
  • Registered ECC design corrects single-bit errors and buffers signals for stable fully-populated operation
  • 1 V operating voltage matches the platform specification for correct power delivery
  • 288-pin RDIMM form factor fits the required motherboard slots exactly

Capacity and form factor

This 384 GB kit contains four 96 GB DDR5 registered DIMMs built to the 288-pin RDIMM standard. It runs at 6400 MT/s with CL52 latency at 1.10 V and uses a 2Rx4 rank layout with on-die ECC. The modules are validated for the Supermicro X14SDV-36C-SP3F motherboard so the memory controller recognises the full capacity at rated speed.

Who this suits and who it does not

The kit targets administrators expanding a Supermicro X14SDV-36C-SP3F platform that requires registered ECC memory in a four-module population. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC modules, or a different pin count should select alternative memory because this product is a registered 288-pin RDIMM only.

Deciding specification

The registered 2Rx4 RDIMM organisation combined with 1.10 V operation and CL52 timing at DDR5-6400 is the single parameter that determines whether the motherboard will initialise all four slots at full frequency. Verify the board's qualified-vendor list and population rules before ordering.

Questions about this item

Will the 1.10 V 2Rx4 modules need active cooling in a fully populated chassis?

The kit has no heat spreader and runs at 1.10 V; in a dense server airflow is normally sufficient, but verify your chassis cooling plan for sustained all-core workloads.

At what point does the CL52 latency or 6400 MT/s ceiling limit throughput under continuous load?

The 6400 MT/s rated speed and CL52 timing are the maximum JEDEC values; sustained heavy traffic will hit the bus bandwidth limit before any lower throttle point appears.

How much power do the four 96 GB RDIMMs draw when the server runs 24/7?

Each module operates at 1.10 V DDR5 standard voltage; total draw scales with capacity and activity, so expect roughly four times a single 96 GB RDIMM's typical load power.
