System-Specific DDR5 ECC RDIMM Kit

This 64GB kit contains two 32GB DDR5-6400 registered ECC modules built for the Supermicro X14SDW-36C-SP9F motherboard. It matches the exact rank, voltage and timing the board's memory controller expects so the full capacity is recognised at rated speed.

288-Pin Registered Form Factor

The 288-pin RDIMM design fits only boards that require registered memory; it will not work in UDIMM or SODIMM slots. Registered buffering offloads the memory controller, allowing every slot to run fully populated while on-die ECC corrects single-bit errors before they cause data corruption or unplanned reboots.

Direct Replacement for Lower-Capacity Kits

This kit replaces smaller DDR5 RDIMM sets when the workload demands the full 64GB at 6400 MT/s with CL52 latency and 1.1V operation. The upgrade is worth it when the server's population rules allow two 2Rx4 modules and the application benefits from maximum registered ECC capacity.

Questions about this item

What DDR5 speed and CAS latency does this 64GB kit run at on the Supermicro X14SDW-36C-SP9F?

The kit operates at DDR5 6400 (PC5-51200) with CL52 timing, matching the motherboard's rated memory speed and latency for full-capacity operation.

Does the 288-pin RDIMM form factor and registered design match the Supermicro X14SDW-36C-SP9F memory slots?

Yes, these are 288-pin DDR5 RDIMMs with registered (buffered) architecture, the exact form factor and signalling the X14SDW-36C-SP9F requires — not UDIMM or SODIMM.

What population order should I follow when installing both 32GB modules on the Supermicro X14SDW-36C-SP9F?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for dual-rank 2Rx4 modules.
