Server-grade DDR5 ECC RDIMM kit

This 384GB kit contains eight 48GB DDR5-4800 registered ECC modules built for the Supermicro H14SST-G motherboard. Each DIMM runs at 1.1V with CL40 timing and a 2Rx8 organization. The 288-pin RDIMM form factor matches the board's registered memory slots exactly.

Registered ECC with 2Rx8 rank organization

Registered buffering offloads the memory controller so all eight slots can be populated at full rated speed. On-die ECC corrects single-bit errors in flight, preventing silent data corruption that crashes production workloads. The 2Rx8 density is what the H14SST-G memory controller expects for full-capacity recognition.

Suits Supermicro H14SST-G builds needing maximum

Builders populating every DIMM slot on this specific motherboard get 384GB at DDR5-4800 without downclocking. Systems that require unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or lower total capacities should select a different kit matched to their platform.

Questions about this item

Will the 4800 MHz speed run at its rated frequency on my Supermicro H14SST-G?

The kit is spec-matched to the Supermicro H14SST-G motherboard, so the memory controller recognises the exact rank, voltage and timing at full 4800 MHz capacity.

What does the PC5-38400 designation cap in real-world bandwidth?

PC5-38400 defines the peak transfer rate for DDR5-4800 modules, setting the maximum throughput the memory subsystem can deliver.

Does the 288-pin RDIMM form factor fit every slot on the H14SST-G?

Yes, the 288-pin Registered DIMM matches the board's required form factor and population rules for full-slot installation.
