Exact-Match Server Upgrade

This 48GB DDR5-4800 RDIMM is built for the Supermicro H14SST-G motherboard. It delivers registered ECC operation at 1.1V with CL40 timing so the memory controller recognises full capacity at rated speed. The 2Rx8 organisation and 288-pin form factor match the board's population rules exactly.

Registered ECC For Full-Population Stability

Suited to administrators who need every DIMM slot filled without down-clocking or instability. The buffered architecture offloads the memory controller while ECC corrects single-bit errors on the fly. Not suited to workstations or desktops that accept only unbuffered UDIMM modules.

2Rx8 Rank Determines Slot Population

The dual-rank 2Rx8 layout decides how many modules the H14SST-G can accept per channel and in which order. Consult the motherboard manual for approved DIMM population sequences and maximum supported capacity per slot before purchasing.

Questions about this item

Does the 48GB DDR5 4800 kit ship as a single 288-pin RDIMM or do I need to order additional modules separately?

The package contains one 48GB 288-pin DDR5 RDIMM rated at 4800 MT/s, CL40, 1.10 V, 2Rx8 registered ECC; no extra sticks are required for that capacity.

Should I choose the 48GB 2Rx8 CL40 module or a different capacity for the Supermicro H14SST-G?

Select this 48GB 2Rx8 CL40 RDIMM when your board's qualified-vendor list calls for a 48GB registered ECC DIMM at 4800 MT/s; other capacities have different rank structures and may not match the memory controller's expectations.

What does the 4800 MT/s rating mean once the RDIMM is installed in the H14SST-G?

The module will run at DDR5-4800 (PC5-38400) with CL40 latency at 1.10 V, delivering the full 48 GB capacity the memory controller is programmed to recognise.
