128 GB DDR5-6400 ECC RDIMM kit

This 128 GB kit contains eight 16 GB DDR5-6400 registered ECC modules built for the Supermicro H14DST-F motherboard. Each DIMM runs at 1.1 V with CL52 latency and a 1Rx8 organisation. The registered design lets the board run every slot populated at the rated speed.

Eight-module capacity and headroom

The 128 GB total fills eight slots with 16 GB per module, giving maximum density for this platform. Registered buffering keeps the memory controller stable when all slots are occupied. Workloads that exceed 128 GB will require a motherboard that supports larger DIMMs or more memory channels.

DDR5 RDIMM interface limits

The 288-pin RDIMM form factor fits only DDR5 registered slots and will not work in UDIMM or SODIMM sockets. Rated at PC5-51200 (6400 MT/s), the kit runs at its specified data rate when the motherboard memory controller supports that speed. ECC corrects single-bit errors on the fly, but cannot protect against multi-bit failures.

Questions about this item

Will the eight 16 GB DDR5-6400 RDIMMs run at rated speed when fully populating the Supermicro H14DST-F?

The kit is an exact-match upgrade for the H14DST-F; its 1Rx8 registered ECC design, 1.1 V voltage and CL52 timing match the board's memory-controller requirements so all eight slots can run at DDR5-6400 when populated per the manual.

How can I verify the 128 GB kit is operating at DDR5-6400 with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode or CPU-Z; it should report 6400 MT/s, CL52, 1.1 V, registered ECC and 128 GB total across the eight 16 GB modules.

What exactly ships in the box and is any extra hardware needed?

The package contains the 128 GB kit as eight 16 GB 288-pin DDR5-6400 RDIMMs; no heat spreaders, cables or additional parts are included, and no separate components are required for installation.
