Four green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 256GB 4x64GB DDR5 5600 PC5-44800 CL46 1.1V 2Rx4 ECC RDIMM Supermicro X14SDW-36CE-SP9F memory upgrade

SKU CH-ZF49-B0XFP

256GB DDR5 5600 ECC registered RDIMM kit validated for the Supermicro X14SDW-36CE-SP9F motherboard

  • Total capacity256 GB (4 × 64 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Rated voltage1.1 V

Size 256GB 4X64GB

  • 256 GB total capacity from four 64 GB modules for maximum server density
  • DDR5 5600 speed rated at PC5-44800 with CL46 latency for rated throughput
  • Registered ECC architecture with 2Rx4 organisation corrects single-bit errors and stabilises fully populated slots
  • 10 V operation matches the platform voltage specification for reliable recognition
  • 288-pin RDIMM form factor verified for Supermicro X14SDW-36CE-SP9F motherboard compatibility

Exact-Match DDR5 Server Upgrade

This 256GB kit contains four 64GB DDR5 5600 PC5-44800 Registered ECC RDIMMs built to the precise rank, voltage, and timing the Supermicro X14SDW-36CE-SP9F memory controller expects. CL46 latency and 1.1V operation ensure the modules are recognised at full capacity and run at their rated speed without manual tuning. The 2Rx4 organisation and 288-pin RDIMM form factor match the board's population rules exactly.

Suited for Fully Populated Server Builds

Administrators expanding a Supermicro X14SDW-36CE-SP9F to its maximum supported DIMM count will appreciate the registered architecture that offloads the memory controller when every slot is filled. ECC corrects single-bit errors on the fly to prevent silent data corruption in production workloads. Builders using consumer UDIMMs, SODIMMs, or non-ECC modules should look elsewhere because this board requires registered DDR5 RDIMMs.

256GB Capacity for Memory-Intensive Services

Four ranks per module across four DIMMs deliver 256GB of addressable memory for virtualisation hosts, in-memory databases, and large-scale container deployments. The kit runs out of headroom when workloads exceed this total or when the platform's maximum supported capacity per socket is lower than the installed amount. Consult the system manual for approved population order and per-socket limits before installation.

Questions about this item

Does my Supermicro X14SDW-36CE-SP9F motherboard need a specific BIOS version to recognise the full 256GB kit?

The kit is an exact-match upgrade for the X14SDW-36CE-SP9F at DDR5-5600 CL46 1.1V. Consult your motherboard manual for supported capacities, approved DIMM population order, and any BIOS update requirements before installation.

Can I add these four 64GB DDR5 RDIMMs alongside existing DDR5 modules in the same server?

Mixing registered ECC modules of different ranks, speeds, or voltages can prevent full-capacity operation. For stable performance, populate all slots with identical 2Rx4 PC5-44800 CL46 1.1V RDIMMs per the board's population rules.

How do I confirm the system is running the kit at DDR5-5600 with ECC active after installation?

Enter the BIOS or use a tool like dmidecode to verify each slot shows 64GB at 5600 MT/s, CL46, 1.1V, Registered ECC, and 2Rx4 organisation. Run a memory test to validate error-correction functionality.
