64GB DDR4 Kit for Gigabyte Boards

This 64GB kit contains two 32GB DDR4 2666 modules built for Gigabyte C246-WU4 and X570 AORUS motherboards. It runs at 1.2V with CL19 timings in an unbuffered, non-ECC 288-pin DIMM format. The matched pair is suited for workstations and high-capacity desktop builds that need 64GB in two slots. It is not for systems limited to lower maximum memory or boards that require registered or ECC modules.

Standard Voltage and Unbuffered Design

Operating at the standard 1.2V DDR4 voltage, the modules draw typical power for this speed and density without extra cooling hardware. The unbuffered layout keeps electrical loading low on the memory controller at 2666 MT/s. No heat spreader is fitted, so airflow across the sticks handles thermals in a normal chassis. Noise and power remain at baseline DDR4 levels for this configuration.

Matched Pair for Dual-Channel Operation

The kit supplies two identical 32GB sticks so the board can run dual-channel mode immediately. Manufacturer guidance recommends matched pairs to maximise performance and avoid mixed-module downclocking. A 64-bit operating system is required to address the full 64GB capacity. The board supports up to 128GB across four sockets if further expansion is needed later.
