Exact-match DDR5-5600 kit for Supermicro H14DST-F

This 256GB kit contains four 64GB DDR5 RDIMMs rated at 5600 MT/s with CL46 timings and 1.1V operation. It is built as a direct upgrade for the Supermicro H14DST-F motherboard so the memory controller recognises every module at its rated speed.

256GB registered ECC capacity and headroom

Four dual-rank 2Rx4 modules fill the board with registered ECC memory that offloads the controller and corrects single-bit errors on the fly. The kit runs at the full 5600 MT/s data rate while all slots remain populated, stopping silent data corruption before it reaches production workloads.

DDR5 RDIMM interface limits

The 288-pin registered form factor is mandatory for this platform; UDIMM or SODIMM modules will not fit or function. Population rules and maximum supported capacities are defined by the motherboard manual, so verify the approved DIMM order and total capacity before installation.

Questions about this item

Will this DDR5-5600 2Rx4 registered ECC kit run at full speed alongside older DDR5 modules I keep in the Supermicro H14DST-F?

The kit is spec-matched to the H14DST-F memory controller at 5600 MT/s, 1.1 V, CL46 and 2Rx4 rank. Mixing different speeds, ranks or voltages will force the board to down-clock all DIMMs to the slowest common setting, so full rated performance is only guaranteed when every populated slot uses identical modules.

How can I confirm the 256 GB kit is recognised at full capacity and running at DDR5-5600 after installation?

Enter the BIOS and verify that all four slots show 64 GB each, total 256 GB, with the memory frequency reported as 5600 MT/s (PC5-44800) and CAS latency at CL46. The registered ECC design also logs corrected single-bit errors in the system event log, confirming ECC is active.

What ships in the box and do I need any extra parts to install the four 64 GB RDIMMs in the H14DST-F?

The package contains the four 288-pin DDR5 registered ECC DIMMs only. No heat spreaders, cables, tools or additional brackets are included or required; the modules seat directly into the motherboard's DDR5 RDIMM slots.
