Targeted server upgrade

This 384GB kit contains eight 48GB DDR5 Registered ECC RDIMMs built for the Supermicro H14DST-F motherboard. It delivers the exact rank, voltage, and timing the board's memory controller expects for full-capacity recognition at rated speed.

DDR5 RDIMM population limits

Registered DIMMs allow every slot to run fully populated at 6400MHz, while ECC corrects single-bit errors on the fly. The motherboard manual defines the supported capacities and required DIMM population order for this 288-pin form factor.

Straightforward installation

Modules key into the 288-pin slots in the sequence the manual specifies; no heat spreaders are fitted. Errors usually come from ignoring the board's population rules or mixing ranks, so verify the configuration before seating the kit.

Questions about this item

Should I choose the 384GB kit with eight 48GB modules or a smaller capacity?

The kit provides 384GB total using eight 48GB RDIMMs, matching the Supermicro H14DST-F's supported population for full-capacity operation at DDR5-6400.

What does the DDR5-6400 rating mean once the modules are installed in the server?

The memory controller will run the kit at 6400 MT/s with CL52 latency at 1.1V, delivering the rated PC5-51200 bandwidth when all slots are populated.

How does the 288-pin RDIMM interface and registered ECC design affect real-world limits?

The registered buffer reduces electrical load on the controller, allowing all eight slots to run at 6400 MT/s, while ECC corrects single-bit errors to prevent data corruption.
