  • 32 GB 2Rx4 registered ECC RDIMM enables full-capacity population
  • Registered buffer offloads controller for stable multi-DIMM operation
  • ECC corrects single-bit errors preventing silent data corruption
  • 288-pin DDR5 form factor fits required server memory slots

System-specific DDR5 upgrade

This 32 GB DDR5-6400 ECC RDIMM is built to the exact rank, voltage and timing the Supermicro X14SDW-42C-SP9F memory controller expects so the module is recognised at full capacity and runs at its rated speed. It targets administrators who need registered error-correcting memory for a single supported platform.

Sustained-load stability

Registered buffering offloads the memory controller so every populated slot can operate at the full 6400 MT/s data rate under continuous throughput while on-die ECC corrects single-bit errors in real time preventing silent data corruption during long-running workloads.

Pre-installation checklist

Verify the motherboard manual for approved DIMM population order maximum supported capacity per slot and any BIOS revision requirements before ordering because server memory rules differ by model and an incorrect configuration will prevent the system from posting.

Questions about this item

How much power does this 1.1V DDR5 RDIMM draw when the server runs continuously?

The module operates at 1.10V, the standard voltage for DDR5 RDIMMs, so power draw stays within the platform's registered DIMM budget even with all slots populated.

What motherboard slot and population rules must my Supermicro X14SDW-42C-SP9F already have free for this 288-pin RDIMM?

The board needs an open 288-pin DDR5 RDIMM slot and must follow its manual's population order; this 2Rx4 registered ECC kit matches the exact rank, voltage and timing the controller expects.

Will this 2Rx4 CL52 registered ECC kit run at 6400 MT/s alongside older DDR5 modules I keep in the same system?

The module is spec-matched to DDR5 6400 (PC5-51200) with CL52 timing; mixing ranks or speeds can force the controller to downclock all channels to the slowest common settings.
