64GB DDR5 ECC RDIMM kit for Supermicro H14DSG-O-CPU

This 64GB kit contains four 16GB DDR5 6400MHz registered ECC modules built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU motherboard expects. The 288-pin RDIMM form factor matches the board's memory slots so the system recognises the full capacity at its rated speed without manual tuning.

Sustained enterprise workloads

Registered architecture buffers the address and command signals so every slot runs fully populated at 6400MHz while ECC corrects single-bit errors on the fly. The 1.1V operating voltage keeps power draw consistent during long compute runs, preventing the silent data corruption and unplanned reboots that unbuffered memory can allow under continuous load.

288-pin RDIMM modules without heat spreaders

The bare-module design fits tight server DIMM arrays where oversized spreaders would block adjacent slots or airflow. Each 1Rx8 module uses major OEM Samsung, Micron or Hynix ICs selected for the Supermicro platform's population rules. Builders who need a different capacity, rank configuration or UDIMM form factor should verify their motherboard manual before purchase.

Questions about this item

How much heat and power will the 1.1V 6400MHz DDR5 RDIMM kit draw under continuous load?

The modules run at 1.10V, the standard voltage for DDR5-6400, so power draw and heat output match the JEDEC baseline for this speed and capacity.

What motherboard slot and population rules must my Supermicro H14DSG-O-CPU already have for this 4x16GB kit to work?

The board needs four 288-pin DDR5 RDIMM slots and must support 1Rx8 registered ECC modules populated per the manual's approved order for 64GB total capacity.

Will the CL52 1Rx8 registered ECC timing work with older DDR5 modules I keep in the same server?

Mixing different CAS latencies, ranks, or voltages can prevent the memory controller from training at 6400MHz; the manufacturer advises checking the motherboard manual for supported mixed-population configurations.
