128 GB DDR5 kit for Supermicro X14SAE

This 128 GB kit contains four 32 GB DDR5 4800 UDIMMs built to the exact rank, voltage and timing the Supermicro X14SAE motherboard expects. The modules are Non-ECC, unbuffered and use a 2Rx8 organisation so the board recognises the full capacity at rated speed without manual tuning.

Sustained load behaviour

Major OEM chips from Samsung, Micron or Hynix are tested for stability at DDR5 4800, CL40 and 1.10 V. The memory maintains its rated frequency and latency during extended workloads rather than throttling after a short burst, giving consistent throughput for compile jobs, virtualisation or large datasets.

Thermals and power

Each module runs at the standard 1.10 V with no heat spreader, relying on case airflow for cooling. Power draw stays at the JEDEC baseline for DDR5 4800 2Rx8 UDIMMs, and the bare PCB produces no additional fan noise beyond what the system cooling already provides.

Questions about this item

How much power do the four 32GB DDR5 4800 modules draw when running all day?

Each module operates at 1.10V, and the kit totals 128GB across four 2Rx8 UDIMMs with no heat spreader, so power scales with workload but stays at the standard DDR5 voltage.

What motherboard slot and chipset does this kit require to function?

The kit needs a Supermicro X14SAE motherboard with 288-pin DDR5 UDIMM slots and a memory controller that accepts 2Rx8 non-ECC unbuffered modules at CL40.

Can I mix these 4800 CL40 2Rx8 sticks with slower DDR5 modules already in the board?

The board will run all installed DDR5 at the lowest common speed and loosest timing, so adding slower modules would drop the 4800 CL40 kit to that lower rate.
