  • Registered ECC design offloads the memory controller and corrects single-bit errors automatically
  • 10 V operation at CL40 latency matches the Supermicro H14DST-FL memory-controller specification
  • 288-pin RDIMM form factor fits the board's DIMM slots and population rules exactly

Exact-match upgrade for Supermicro H14DST-FL

This 768GB kit delivers 16 registered ECC DDR5 RDIMMs at 4800MHz with CL40 timing and 1.1V operation. The 2Rx8 organisation matches the memory controller expectations of the Supermicro H14DST-FL motherboard so the full capacity is recognised at rated speed.

Registered ECC architecture for full population

Registered buffering offloads the memory controller allowing every one of the 288-pin slots to run fully populated at 48GB per module. On-die ECC corrects single-bit errors in flight preventing silent data corruption and unplanned reboots in production workloads.

Lifetime replacement and US technical support

The kit ships as a single validated 16-module package backed by a lifetime replacement warranty. Free US-based technical support is available for installation guidance and population-order verification before deployment.

Questions about this item

Will 16 RDIMMs at 4800 MHz CL40 exceed the Supermicro H14DST-FL memory-controller limit for full-speed operation?

The kit is validated for the Supermicro H14DST-FL; all 16 slots run at the rated DDR5-4800 speed when populated per the board's population rules.

What thermal and power behaviour should I expect from 768 GB of registered DDR5 running continuously at 1.1 V?

Registered modules offload the controller and operate at 1.1 V with no heat spreaders; sustained loads stay within standard server airflow and power envelopes.

Does the Supermicro H14DST-FL require a specific CPU generation or BIOS revision before this 16 × 48 GB kit will be recognised?

Compatibility is confirmed for the H14DST-FL motherboard; consult the board manual for approved DIMM population order and any BIOS updates before installation.
