  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 10 V operation at 2Rx8 rank aligns with the board's voltage and population rules
  • 288-pin RDIMM form factor verified for the Supermicro H14DSH motherboard

Exact-fit Supermicro H14DSH memory kit

This 576 GB kit contains twelve 48 GB DDR5 4800 RDIMMs built to the Supermicro H14DSH memory-population rules. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed. It is intended for administrators upgrading that specific platform.

Registered ECC RDIMM form factor

The modules use the 288-pin RDIMM form factor with 2Rx8 organisation and CL40 timing at 1.1 V. A UDIMM or SODIMM will not fit the board's registered DIMM slots and will not be recognised by the memory controller.

576 GB total capacity

Twelve dual-rank modules deliver the maximum density this kit provides for memory-intensive workloads such as virtualisation and in-memory databases. Capacity stops at 576 GB; configurations requiring more memory need a different kit or a platform with additional channels.

Questions about this item

How does the 4800 MT/s speed translate to actual throughput in a Supermicro H14DSH server?

The kit operates at the JEDEC-standard DDR5 4800 rate with CL40 latency, so each module transfers data at the rated 4800 MT/s when the motherboard populates all twelve slots.

What does the PC5-38400 designation mean for memory-controller limits on this board?

PC5-38400 is the JEDEC peak-transfer label for DDR5 4800; the H14DSH memory controller will run the kit at that speed provided the BIOS is current and the DIMMs are installed in the supported population order.

Will the twelve 288-pin RDIMMs fit the H14DSH memory slots without clearance issues?

Yes — the modules are standard-height 288-pin registered DIMMs with no heat spreader, matching the H14DSH slot layout and leaving room for CPU cooler clearance.
