Size 384GB 4X96GB

  • 384 GB total capacity from four 96 GB modules for high-density server workloads
  • DDR5 6400 speed with CL52 latency delivers rated throughput on supported platforms
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 10 V operation matches the motherboard's memory controller specification exactly
  • 288-pin RDIMM form factor fits the Supermicro X14SDW-40C-SP9F without adapters

Exact-match upgrade for Supermicro X14SDW

This 384GB kit contains four 96GB DDR5 RDIMMs built to the precise rank, voltage and timing the Supermicro X14SDW-40C-SP9F memory controller expects. Registered ECC architecture offloads the controller so every slot runs fully populated at the rated 6400 MT/s speed. The modules arrive new and ready for installation in the 288-pin DDR5 slots your board requires.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller, allowing all four DIMMs to operate continuously at 1.1V and CL52 without the signal degradation that can appear on unbuffered modules under heavy throughput. ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during long production runs. The 2Rx4 organisation maintains bandwidth consistency across the full 384GB capacity.

288-pin DDR5 RDIMM form factor

Only the 288-pin Registered DDR5 form factor fits the Supermicro X14SDW-40C-SP9F; UDIMM or SODIMM modules will not seat or function. Verify your motherboard manual for supported capacities and approved population order before purchase.

Questions about this item

How much power does each 96GB DDR5 6400 module draw at its rated 1.1V?

Each module operates at 1.1V as specified, which is the standard DDR5 voltage for registered ECC DIMMs; total system power will depend on the Supermicro X14SDW-40C-SP9F memory controller and population of all four slots.

Does the Supermicro X14SDW-40C-SP9F motherboard need a specific BIOS version or CPU to recognise this 384GB 4x96GB kit?

The kit is spec-matched to the Supermicro X14SDW-40C-SP9F for DDR5 6400 2Rx4 registered ECC at 1.1V; consult your motherboard manual for supported capacities, approved DIMM population order, and any required BIOS updates before installation.

Can I mix these 2Rx4 CL52 RDIMMs with older DDR5 ECC modules of different rank or latency on the same board?

Mixing ranks, latencies or voltages is not recommended; the board's memory controller expects uniform 2Rx4 CL52 1.1V registered DIMMs for stable operation across all populated slots.
