Exact-match server upgrade

This 384GB kit contains four 96GB DDR5 registered ECC RDIMMs built for the Supermicro H14SHM motherboard. The modules run at DDR5-6400 with CL52 timing at 1.1V, matching the board's required rank, voltage and timing so the controller recognises full capacity at rated speed.

Capacity and headroom

Four dual-rank 2Rx4 modules fill the supported slots and deliver 384GB of registered memory with on-the-fly single-bit error correction. The registered architecture keeps the memory controller stable when every slot is populated, but the kit cannot exceed the motherboard's maximum supported capacity or population rules.

DDR5 288-pin RDIMM form factor

These modules use the 288-pin DDR5 RDIMM interface this board requires; they are not compatible with UDIMM or SODIMM slots. Verify your system manual for approved DIMM population order and maximum capacity before installation.

Questions about this item

Will this 384GB DDR5 6400 kit work in a Supermicro H14SHM that already has older DDR5 RDIMMs installed?

The kit is validated for the H14SHM motherboard. Mixing it with existing DDR5 RDIMMs requires matching speed, voltage, rank, and ECC type; consult the board manual for approved population rules before combining modules.

How can I verify the 4x96GB modules are running at DDR5 6400 CL52 after installation?

Enter the BIOS or use a hardware-info tool to confirm each slot shows 6400 MT/s, CL52 timings, 1.10 V, and registered ECC status for all four 96 GB DIMMs.

What comes in the box and do I need extra parts to install the 288-pin RDIMMs?

The box contains the four 96 GB DDR5 6400 CL52 1.10 V ECC registered RDIMMs. No additional components are required; the modules plug directly into the H14SHM's 288-pin DIMM slots.
