Exact-match DDR5-6400 kit for Supermicro H14SSF

This 384 GB kit contains four 96 GB Registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. It is intended for administrators who need the full capacity recognised at rated speed without manual tuning.

Four dual-rank 96 GB modules at CL52 1.10 V

The Registered architecture lets every slot run fully populated at 6400 MT/s while ECC corrects single-bit errors on the fly. Headroom ends when the board's own population rules or maximum supported capacity are reached.

288-pin RDIMM form factor with no heat spreader

The modules fit only DDR5 RDIMM slots — UDIMM or SODIMM boards will not accept them. Verify the H14SSF manual for approved DIMM order and population limits before installation.

Questions about this item

Will the 288-pin DDR5 6400 RDIMMs run correctly alongside any existing DDR5 modules I keep in the Supermicro H14SSF?

The kit is spec-matched to the board's memory-population rules; mixing with other DDR5 RDIMMs of different rank, voltage or timing may prevent full-speed operation, so populate all slots with this matched 4x96GB set for guaranteed 6400 CL52 1.1V operation.

How can I verify the kit is running at DDR5 6400 CL52 with ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 6400 MT/s, CAS latency 52, voltage 1.1V and ECC mode enabled for all four DIMMs.

What exactly ships in the box and is anything else required to install the 384GB kit?

The package contains the four 96GB 2Rx4 288-pin DDR5 6400 CL52 1.1V ECC Registered RDIMMs; no extra cables, brackets or software are needed — just follow the motherboard manual for correct slot population.
