Supermicro H14DST-FL Memory Kit

This 256GB kit contains sixteen 16GB DDR5 RDIMMs built for the Supermicro H14DST-FL motherboard. Each module is a registered ECC DIMM rated at 4800 MT/s with CL40 latency and 1.1V operation. The exact rank and timing match the board's memory controller requirements for full-capacity recognition.

DDR5 4800 Registered ECC Limits

Registered buffering lets every slot run fully populated at the rated 4800 MT/s speed without overloading the memory controller. ECC corrects single-bit errors on the fly to prevent silent data corruption. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit or function in this platform.

256GB Capacity and Headroom

Sixteen 1Rx8 modules deliver 256GB total capacity for memory-intensive server workloads. Full population at rated speed is supported when the motherboard's population rules are followed. Builders needing more than 256GB must verify the board's maximum supported capacity and approved DIMM configurations before purchase.

Highlights

Questions about this item

Should I choose the 16-module kit or a smaller capacity for my Supermicro H14DST-FL?

The kit provides 256 GB across 16 modules of 16 GB each, filling every DIMM slot the board supports for maximum registered ECC capacity.

What does the 4800 MT/s rating deliver in a real server workload?

At DDR5 4800 the modules transfer data at up to 38 400 MB/s per channel, letting the memory controller run all 16 ranks at rated speed without downclocking.

How does the 288-pin RDIMM interface and registered design affect what I can install?

The 288-pin RDIMM form factor matches the board's registered DIMM slots; the registered buffer lets all 16 modules operate at full 256 GB capacity while ECC corrects single-bit errors.
