Exact-match DDR5 upgrade for Supermicro H14SHM

This 576GB kit contains twelve 48GB registered ECC RDIMMs built to the memory controller's precise rank, voltage and timing requirements. It targets administrators who need the full capacity their server board can recognise at rated speed.

Capacity and headroom

Twelve dual-rank modules deliver 576GB of DDR5-6400 bandwidth with CL52 latency at 1.1V. ECC corrects single-bit errors on the fly while registered buffering keeps every slot stable when fully populated. The kit stops at the board's maximum supported configuration.

288-pin RDIMM fitment

The modules use the 288-pin RDIMM form factor the H14SHM requires — not UDIMM or SODIMM. Population order and approved capacities must follow the motherboard manual. No heat spreaders are included, so airflow in the chassis must handle thermal load.

Questions about this item

Will the 12x48GB DDR5 6400MHz CL52 ECC RDIMM kit run at rated speed on a Supermicro H14SHM board with existing DDR5 modules?

The kit is spec-matched to the H14SHM memory controller and population rules; install it in the slots the manual specifies and the board should recognise the full 576GB at DDR5-6400.

How can I confirm the 576GB kit is operating with ECC and registered buffering after installation?

Check the BIOS memory information for 576GB total, DDR5-6400 speed, ECC enabled and registered DIMM type reported for each of the 12 slots.

Does the 12x48GB DDR5 6400MHz CL52 1.1V RDIMM package include any cables, heat spreaders or installation tools?

The box contains only the twelve 48GB 288-pin ECC RDIMM modules; no heat spreaders, cables or tools are supplied.
