Exact-Match 384 GB DDR5 Kit

This 384 GB kit contains four 96 GB DDR5 RDIMM modules rated at 6400 MT/s (PC5-51200) with CL52 latency and 1.1 V operation. It is built for the Supermicro X14SDW-72C-SP9F motherboard and delivers registered ECC memory that the server's controller recognises at full capacity and rated speed.

Verify Motherboard Population Rules

Before ordering, consult the Supermicro X14SDW-72C-SP9F manual for supported capacities, approved DIMM population order, and installation steps. The board requires 288-pin Registered RDIMMs; UDIMM or SODIMM modules will not fit or function. Ensure your configuration matches the 2Rx4 rank and 1.1 V specification exactly.

Registered ECC Architecture Benefits

The registered (buffered) design offloads the memory controller so every slot runs fully populated at full capacity. On-die ECC catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots in production workloads. No heat spreaders are included in the package.

Questions about this item

Does the 384GB kit contain four 96GB modules or do I need to buy extra DIMMs?

The kit includes four 96GB DDR5 RDIMMs for a total of 384GB; no additional modules are required.

Why is this kit listed as CL52 2Rx4 1.1V and what happens if I mix different timings?

CL52, dual-rank x4 organisation and 1.1V are the exact specifications the Supermicro X14SDW-72C-SP9F memory controller expects; mixing other timings or ranks can prevent the system from booting at 6400MHz.

Will the server actually run at 6400MHz with all four slots populated?

Yes — the registered ECC design and 2Rx4 layout let the board run all four slots at the rated 6400MHz (PC5-51200) without down-clocking.
