Capacity and population

This 512 GB kit contains eight 64 GB DDR5-4800 registered ECC RDIMMs built to the PC5-38400 standard. Each module runs at 1.1 V with CL40 latency and a 2Rx4 rank structure that lets a supported motherboard fill every slot at rated speed.

Supermicro H14DSG-O-CPU fitment

The kit is validated for the Supermicro H14DSG-O-CPU motherboard, so the 288-pin registered form factor matches the board's memory population rules exactly. Systems needing a different DIMM type, lower capacity per module, or non-ECC memory will not accept this kit.

Thermals and power

Modules operate at the standard 1.1 V DDR5 voltage without heat spreaders, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller, keeping power draw predictable when all eight slots are populated.

Questions about this item

Will this 8-module DDR5-4800 kit run at its rated speed alongside older DDR5-4800 RDIMMs I already have?

Mixing kits with identical DDR5-4800, CL40, 1.1V, 2Rx4 specifications usually works, but the motherboard will train all slots to the slowest common timing; for guaranteed stability use matched kits.

How can I confirm the 512GB kit is detected at DDR5-4800 CL40 after installation?

Enter the server BIOS and verify the memory information screen reports 512GB total, DDR5-4800 speed, and CL40 latency with ECC active.

Does the package include only the eight 64GB RDIMMs or are extra items such as a heat-spreader kit supplied?

The box contains the eight 64GB DDR5-4800 2Rx4 Registered ECC RDIMMs and nothing else; no heat spreaders or additional accessories are included.
