  • 64 GB capacity lets you run larger workloads without swapping
  • DDR5 5600 speed with CL46 latency delivers high throughput for server tasks
  • ECC registered design detects and corrects data errors in critical systems
  • 1 V operation reduces power draw in dense memory configurations
  • Validated for Supermicro X13SEDW-F, X13SEED-F, X13SEED-SF, X13SEFR-A and X13SEI-F motherboards

Server ECC upgrade

This 64GB DDR5 module is a registered ECC RDIMM built for Supermicro X13 series motherboards. It targets workstations, NAS appliances, servers and network switches that require error-correcting memory.

Compatibility check

Verify the board is one of the listed Supermicro X13 models and that the memory slots accept 288-pin registered DIMMs. The module will not work in standard desktop PCs and must not be mixed with unbuffered or load-reduced ECC memory.

Build integration

The single 64GB stick occupies one slot, leaving remaining channels free for additional matching modules. It runs at 1.1V under JEDEC PC5-44800 timing, so no manual voltage adjustment is required.
