Purpose-built server memory kit

This 128GB kit contains four 32GB DDR5 RDIMMs rated at 5600 MT/s with CL46 latency and 1.1V operation. It is designed for administrators upgrading the Supermicro H14SST-G motherboard with registered ECC memory that matches the board's qualified vendor list.

Registered ECC with 2Rx8 organization

The modules use a 2Rx8 rank configuration and registered buffering, which the H14SST-G memory controller requires for full-capacity operation across all populated slots. ECC corrects single-bit errors in flight, preventing silent data corruption in production workloads.

Four-slot population on H14SST-G

The 288-pin RDIMM form factor fits the motherboard's DDR5 slots directly; no heat spreaders are present, so clearance around adjacent components is maximized. Installers should follow the board manual's population order to enable all 128GB at the rated 5600 speed.

Questions about this item

Will the DDR5-5600 rating hold at full speed when all four 32 GB modules are populated?

Yes — the kit is spec-matched to the Supermicro H14SST-G memory controller, so the registered ECC modules run at the rated 5600 MT/s with CL46 timing across all slots.

Does the 288-pin RDIMM form factor match the Supermicro H14SST-G DIMM slots?

The board requires 288-pin registered DDR5 RDIMMs, and this kit uses exactly that form factor; UDIMM or SODIMM modules will not fit.

How much physical space does the 128 GB kit need inside the chassis?

Four standard-height 288-pin RDIMMs occupy four adjacent DIMM slots on the motherboard; no heat spreaders are fitted, so clearance is the same as any bare DDR5 registered module.
