Size 384GB 4X96GB

  • 384 GB total capacity delivered as four 96 GB modules for dense server workloads
  • DDR5 6400 (PC5-51200) speed with CL52 latency runs at rated frequency on the target board
  • Registered ECC design with 2Rx4 organisation offloads the memory controller and corrects single-bit errors

  • 288-pin RDIMM form factor verified for the Supermicro X14SDW-36C-SP9F motherboard

384GB DDR5-6400 Registered ECC Kit

This 384GB kit contains four 96GB DDR5-6400 (PC5-51200) Registered ECC RDIMMs. Each module runs at 1.1V with CL52 latency and a 2Rx4 organisation. The 288-pin registered design is built for servers that require buffered memory with error correction. It is intended for administrators expanding memory in compatible Supermicro platforms.

Suited for Supermicro X14SDW-36C-SP9F upgrades

The kit matches the Supermicro X14SDW-36C-SP9F motherboard's DDR5-6400 Registered RDIMM requirement. Builders using consumer UDIMMs, SODIMMs, or non-ECC modules should look elsewhere. Systems that do not support 2Rx4 registered DIMMs or that limit total capacity below 384GB will not accept this kit.

DDR5-6400 CL52 2Rx4 Registered ECC spec

The memory controller expects DDR5-6400 (PC5-51200) with CL52 timing, 1.1V operation and a 2Rx4 registered layout. If the platform requires a different speed, voltage, rank structure or unbuffered modules, this kit will not function correctly. Verify the motherboard manual for exact population rules before installing.

Questions about this item

Will the 96 GB RDIMM modules need replacement if I upgrade the Supermicro X14SDW-36C-SP9F to a newer CPU?

The kit is validated for that motherboard at DDR5 6400 CL52 1.1 V. A CPU change may alter supported speeds or capacities, so consult the board manual for the new processor's qualified memory list before swapping.

What limit appears first when all four slots run 2Rx4 registered ECC at 6400 MT/s continuously?

The memory controller's maximum ranked capacity per channel is reached before thermal or power limits, so population rules in the Supermicro manual dictate the practical ceiling.

How much extra heat and power do the four 96 GB registered ECC modules add under 24/7 load?

Each module runs at 1.1 V without a heat spreader; total draw stays within standard RDIMM limits, and the motherboard's DIMM airflow design handles the thermal load.
