Capacity and Configuration

This 384GB kit delivers six 64GB DDR5 registered ECC modules rated at 4800 MT/s with CL40 timing and 1.1V operation. The 2Rx4 organisation matches the Supermicro H14DST-F memory controller requirements for full-capacity recognition.

Target Use and Limits

Suited for administrators populating every slot on a supported Supermicro H14DST-F platform with registered ECC memory. Not suited for systems that accept only unbuffered UDIMMs, laptops requiring SODIMMs, or boards limited to lower maximum capacities per DIMM.

Included Items and Effect

The package supplies the six 288-pin RDIMMs as a matched kit so the motherboard can initialise all channels at the rated 4800 speed without manual timing adjustments. No heat spreaders, cables, software licences or additional accessories are included.

Questions about this item

What motherboard must I already have for this 384GB DDR5 4800 kit to work?

This kit is validated for the Supermicro H14DST-F motherboard and requires its 288-pin RDIMM slots and registered memory controller.

Can I mix these 64GB 2Rx4 modules with older DDR5 DIMMs on the same board?

Mixing ranks or capacities can prevent the H14DST-F from running all channels at 4800 CL40; the manual specifies exact population rules for full 384GB operation.

How do I confirm the system sees all 384GB at DDR5 4800 CL40 after installation?

Check BIOS memory information for 384GB total, DDR5 4800 speed, CL40 timings, 1.10V voltage and registered ECC status on all six slots.
