Server Memory Kit

This 256GB kit contains four 64GB DDR5 registered DIMMs built for the Supermicro H14DST-F motherboard. Each module runs at 4800MHz with CL40 latency at 1.1V. The 2Rx4 organisation and ECC registration match the board's memory controller requirements exactly.

Registered ECC Architecture

Registered buffering reduces electrical load on the memory controller when all slots are populated. On-die ECC detects and corrects single-bit errors automatically, preventing silent data corruption and unplanned reboots in production workloads. The modules operate at the standard 1.1V DDR5 voltage.

288-Pin RDIMM Form Factor

The 288-pin registered DIMM form factor is the only type the H14DST-F accepts; UDIMM or SODIMM modules will not fit. No heat spreaders are fitted, so airflow clearance follows the motherboard's standard DIMM spacing. Verify the board's population order in its manual before installation.

Questions about this item

Will the 4x64GB DDR5 RDIMM kit need any firmware updates or component swaps after installation?

The modules are an exact-match upgrade for the Supermicro H14DST-F, so the memory controller recognises the 2Rx4 rank, 1.10V voltage and CL40 timing at full 4800MHz speed without further changes.

What limit appears first when the 256GB kit runs at DDR5-4800 continuously?

The registered (buffered) architecture offloads the memory controller, allowing every slot to stay fully populated at rated capacity and speed under sustained load.

How much heat and power do the four 64GB DDR5 RDIMMs produce during all-day operation?

Each module runs at 1.10V with no heat spreader; the registered design reduces electrical load on the controller, keeping power draw and thermals low for continuous server use.
