NEMIX RAM

NEMIX RAM 512GB (4x128GB) DDR5 6400 CL52 4Rx4 ECC RDIMM Supermicro X14SDI-36C-SP3F memory upgrade

SKU CH-W261-JAAYX

A 512GB DDR5 ECC Registered RDIMM kit (4×128GB) at 6400 CL52 1.1V, validated for the Supermicro X14SDI-36C-SP3F motherboard

  • Capacity512GB (4 x 128GB)
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 512GB 4X128GB

  • 512 GB total capacity from four 128 GB modules for maximum memory density
  • DDR5 6400 speed with CL52 latency delivers rated throughput for the platform
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the motherboard's memory controller specification exactly
  • 288-pin RDIMM form factor fits the Supermicro X14SDI-36C-SP3F without adapters

Exact-Match Server Upgrade

This 512GB kit contains four 128GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the Supermicro X14SDI-36C-SP3F motherboard expects. It is intended for administrators who need the full capacity recognised at rated speed without manual tuning.

Registered ECC Architecture

Each module is a 288-pin 4Rx4 registered DIMM operating at 1.1V, so the memory controller is buffered and every slot can be populated. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Lifetime Support Included

The kit ships as a matched set of four modules with a lifetime replacement warranty and free US-based technical support. No heat spreaders are fitted, and the package contains only the memory modules themselves.

Questions about this item

Does the 1.1V DDR5 6400 kit hit a thermal limit first under sustained use?

The modules run at 1.1V and have no heat spreader, so sustained loads rely on server chassis airflow to keep temperatures in check.

What noise, heat or power change should I expect with all four 128GB sticks running all day?

Registered DDR5 at 1.1V keeps power draw low per module, but total system heat rises with full population — plan chassis cooling accordingly.

What else must I already own for this 512GB kit to work?

A Supermicro X14SDI-36C-SP3F motherboard with 288-pin DDR5 RDIMM slots and a CPU that supports 4Rx4 registered ECC memory.
