Capacity and purpose

This 384 GB kit contains six 64 GB DDR5 registered ECC RDIMMs built for the Supermicro H14DST-FL motherboard. It targets servers and workstations that require maximum supported memory capacity with error correction and registered signalling.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all slots can run fully populated at the rated 5600 MT/s speed. ECC corrects single-bit errors on the fly to prevent silent data corruption during continuous operation. The modules operate at 1.1 V with CL46 latency.

Pre-order checks

Verify the motherboard manual for approved DIMM population order and maximum capacity per channel before ordering. Confirm the system requires 288-pin registered RDIMMs rather than unbuffered or SO-DIMM form factors. Ensure the BIOS version supports the installed capacity and rank configuration.

Questions about this item

How much power does the 1.1 V DDR5 kit draw when the server runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 384 GB capacity and 5600 MT/s data rate under load.

What motherboard slot and population rules must my Supermicro H14DST-FL already support for this 6 × 64 GB kit?

The board needs six 288-pin RDIMM slots wired for registered ECC memory and a population sequence that accepts 2Rx4 modules in every channel.

Will the registered ECC RDIMMs run at their rated 5600 speed if I keep older DDR5 DIMMs in the remaining slots?

Mixing ranks or speeds usually forces the memory controller to downclock all channels to the slowest common JEDEC setting, so full 5600 MT/s operation is not guaranteed.
