Exact-match DDR5 kit for Supermicro H14DSG-OD

This 384 GB kit contains eight 48 GB DDR5 ECC RDIMM modules rated at 6400 MHz with CL52 latency and 1.10 V operation. Registered 2Rx8 architecture matches the memory controller requirements of the Supermicro H14DSG-OD motherboard so the full capacity is recognised at rated speed. It is intended for administrators expanding a compatible Supermicro server to its maximum supported memory.

Verify motherboard population rules before ordering

Consult the Supermicro H14DSG-OD manual for approved DIMM population order, maximum capacity per slot and any BIOS version requirements. The board requires 288-pin Registered DDR5 RDIMMs; UDIMM or SODIMM modules will not fit. Confirm that your specific system revision supports eight 48 GB modules at the rated frequency.

Registered ECC design keeps all slots stable under

Registered buffering offloads the memory controller so every populated slot runs at full capacity while ECC corrects single-bit errors on the fly. The kit frees you from mixing module capacities or ranks because every DIMM is identical. No heat spreader is included, so ensure your server chassis provides adequate airflow across the bare modules.

Questions about this item

What comes in the 384GB kit and do I need anything else to install it?

The kit contains eight 48GB DDR5 6400MHz CL52 1.1V 2Rx8 288-pin ECC Registered RDIMM modules. No extra parts are required; the modules plug directly into the Supermicro H14DSG-OD motherboard slots.

Should I choose this 8x48GB kit or a different capacity for the H14DSG-OD?

This kit provides the full 384GB capacity across all eight channels. Select it when your workload needs maximum memory bandwidth and capacity; choose a smaller kit only if your application does not require the full population.

What does the 6400MHz CL52 rating mean once the modules are running in the server?

The modules operate at DDR5-6400 (PC5-51200) with a CAS latency of 52 cycles at 1.1V, delivering the exact speed and timing the H14DSG-OD memory controller expects for stable, full-capacity operation.
