Targeted Server Upgrade

This 64GB kit provides two 32GB DDR5 RDIMMs rated at 6400MHz PC5-51200 with CL52 latency and 1.1V operation. It is built specifically for the Supermicro X14SDW-64CM-SP9F motherboard, matching the exact rank, voltage and timing the board's memory controller expects for full-capacity recognition at rated speed.

Registered ECC Form Factor

Each module uses a 288-pin registered DIMM design with 2Rx4 organisation and on-die ECC, delivering the buffered architecture this platform requires for stable fully-populated operation. The registered interface reduces electrical load on the memory controller, while error correction catches and corrects single-bit faults before they affect production workloads.

Enterprise Thermal Profile

Operating at the standard 1.1V DDR5 voltage without a heat spreader, these modules rely on the server chassis airflow for cooling. The registered design and ECC functionality maintain data integrity under sustained load, supporting continuous operation in environments where unplanned reboots or silent data corruption are unacceptable.

Questions about this item

Does this DDR5-6400 kit run at its rated 6400 MT/s on the Supermicro X14SDW-64CM-SP9F?

Yes, the kit is spec-matched to the board's memory controller so it is recognised at full capacity and operates at DDR5-6400 (PC5-51200) with CL52 timing at 1.1 V.

Will these 288-pin RDIMMs physically fit the Supermicro X14SDW-64CM-SP9F slots?

The board requires 288-pin registered RDIMMs; this kit uses that exact form factor — not UDIMM or SODIMM — so the modules seat correctly in the server's DIMM slots.

What population order should I follow when installing the two 32 GB modules?

Install the DIMMs in the sequence specified by the Supermicro X14SDW-64CM-SP9F manual — typically filling the primary channel slots first — then enable ECC in the BIOS to activate registered ECC operation.
