Overview
The GIGABYTE B660 DS3H DDR4 is an ATX form factor motherboard built on the Intel B660 Express Chipset, designed to support 12th Generation Intel Core, Pentium Gold, and Celeron processors using the LGA1700 socket. It is a capable platform for home, office, and entry-level gaming builds that prioritise reliability and value without sacrificing essential modern features. Memory performance is a key strength of this board. Four DDR4 DIMM slots support dual-channel configuration with a maximum capacity of 128 GB. With XMP-compatible modules and the XMP profile activated in BIOS, the board supports speeds reaching DDR4 5333 MHz (overclocked), making it well suited for users who want to extract additional performance from high-speed memory kits. Storage and expansion options are practical and straightforward. Four SATA 6Gb/s connectors handle conventional drives, while a primary PCIe x16 slot at full x16 bandwidth accommodates a discrete graphics card. Additional PCIe slots provide further expansion flexibility. Onboard video output is supported via one HDMI port and one DisplayPort, useful for systems using Intel's integrated graphics. Connectivity at the rear panel includes one USB Type-C port, two USB 3.2 Gen 1 ports, and four USB 2.0/1.1 ports, alongside a PS/2 keyboard port and three audio jacks supporting up to 7.1-channel audio through a Realtek audio codec. Networking is handled by a Realtek Gigabit Ethernet chip delivering speeds up to 1 Gbps. GIGABYTE's Q-Flash Plus feature allows BIOS updates without installing a CPU, memory, or graphics card – simply save the BIOS file to a USB drive and press the dedicated button. RGB Fusion 2.0 enables addressable lighting customisation. The power delivery section uses an 8+2+1 phase design with low RDS MOSFETs and solid capacitors for stable performance under load, fed by an 8-pin solid-pin CPU power connector. Smart Fan 6 provides multi-header fan control supporting both PWM and DC modes, with each header rated up to 24W (12V × 2A) with over-current protection, keeping the system cool and quiet.
