Capacity and purpose

This 384GB kit provides four 96GB DDR5 registered ECC RDIMMs built for the Supermicro H14DST-F motherboard. It targets server administrators who need maximum memory density in a validated configuration. Buyers who need unbuffered UDIMMs or SODIMM form factors cannot use this kit.

Sustained-load behavior

Registered buffering offloads the memory controller so all four slots operate at the rated DDR5 6400 speed with CL52 latency and 1.1V supply. ECC corrects single-bit errors on the fly to prevent silent data corruption during continuous workloads.

Installation notes

The 288-pin RDIMMs install only in the specific DIMM sequence the H14DST-F manual defines; deviating from that order can leave capacity unrecognised. Verify the approved population rules and BIOS version before seating the modules.

Questions about this item

How much power does each 96GB DDR5 module draw at 1.1V during continuous operation?

Each module operates at 1.1V as specified for DDR5 6400 CL52 Registered ECC RDIMMs. The 2Rx4 organization and registered buffer reduce electrical load on the memory controller when all four slots are populated. Actual power draw varies with workload intensity and server configuration.

What motherboard and CPU combination is required to run this 384GB kit at DDR5 6400?

This kit is validated for the Supermicro H14DST-F motherboard. The CPU must support DDR5 6400 Registered ECC memory with 2Rx4 rank structure. Consult your motherboard manual for approved DIMM population order and maximum supported capacity per channel.

Will these DDR5 6400 RDIMMs work alongside slower DDR5 modules already installed in the H14DST-F?

Mixing memory speeds forces all modules to run at the lowest common speed and timing. The motherboard will downclock this CL52 kit to match any slower DDR5 RDIMMs present. For stable operation at the rated 6400 MT/s, populate all channels with identical modules.
