Tailored for GIGABYTE A620I AX

This 64 GB kit uses two 32 GB DDR5 UDIMM modules validated for the GIGABYTE A620I AX Mini-ITX motherboard. It targets builders who need high capacity on a compact platform without ECC or registered buffers. The non-ECC unbuffered design matches the board’s consumer memory controller.

Fits two-slot Mini-ITX layouts

The kit occupies both DIMM slots on the A620I AX, delivering the full 64 GB in a dual-channel configuration. No heat spreader is fitted, keeping module height low for tight cooler clearances in small-form-factor cases. Each module runs at the standard 1.1 V DDR5 voltage.

Steady throughput at JEDEC speeds

Operating at DDR5 4800 with CL40 timings, the modules maintain consistent bandwidth during extended workloads rather than brief bursts. The 2Rx8 organisation supports stable operation at the rated frequency without requiring manual voltage increases or XMP profiles.

Questions about this item

Will the 1.10 V operating voltage limit overclocking headroom under sustained load?

The modules are specified at 1.10 V with CL40 timings at 4800 MT/s; running them at higher voltages or tighter timings would exceed the rated specification.

How much heat will the kit produce during all-day operation without a heat spreader?

At the standard 1.10 V DDR5 voltage the kit draws minimal power, and the bare PCB design relies on case airflow rather than a dedicated spreader for cooling.

Does the GIGABYTE A620I AX motherboard need a specific BIOS version or CPU to recognise this 2Rx8 64 GB kit?

The kit is validated for the GIGABYTE A620I AX Mini-ITX board; install both 32 GB modules in the two DDR5 slots and the system will detect the full 64 GB capacity.
