Show 4 more configurations
  • 256 GB total capacity from four 64 GB modules for maximum server density
  • DDR5 6400 speed with CL52 latency delivers rated bandwidth for demanding workloads
  • Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1 V operation matches the platform's native voltage for reliable initialisation
  • 288-pin RDIMM form factor verified for Supermicro X14SRA-F motherboard compatibility

Exact-Match Kit for Supermicro X14SRA-F

This 256GB kit contains four 64GB DDR5 6400MHz Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro X14SRA-F memory controller expects. It installs as a matched set so the server recognises the full capacity at rated speed.

Registered 4Rx4 Architecture

Each module uses a 4Rx4 organisation with Registered buffering and ECC, operating at 1.1V CL52. The Registered design offloads the memory controller to keep every slot stable when fully populated, while ECC corrects single-bit errors before they affect production workloads.

Suited for X14SRA-F builds needing maximum capacity

Ideal for administrators populating the Supermicro X14SRA-F to its supported limit with validated DDR5 RDIMMs. Not for systems that require UDIMM or SODIMM form factors, non-ECC memory, lower voltages, or different DDR generations.

Questions about this item

What does DDR5 6400 CL52 mean for throughput and latency on the Supermicro X14SRA-F?

The kit runs at 6400 MT/s with a CL52 timing at 1.1 V, so the memory controller sees its rated speed and latency without manual tuning.

How does the PC5-51200 rating relate to the 288-pin DDR5 RDIMM slot on this board?

PC5-51200 is the JEDEC bandwidth designation for DDR5-6400; the 288-pin registered DIMM keying matches the X14SRA-F slots exactly.

Will four 64 GB 4Rx4 registered DIMMs fit the X14SRA-F memory population rules?

The kit provides four 288-pin RDIMMs built to the board's required rank, voltage and timing, so it installs in the supported full-population order.
