About Gigabyte B660M DS3H DDR4 Micro ATX Motherboard
The Gigabyte B660M DS3H DDR4 Micro ATX Motherboard features RGB FUSION 2.0 lighting-effect options offers customized settings with outstanding aesthetics and enables enthusiasts to create a stylish and unique gaming PC.
With durability in mind, GIGABYTE offers a thermal solution for M.2 SSD devices. M.2 Thermal Guard prevents throttling and bottlenecks from high-speed M.2 SSDs as it helps dissipate heat before problems occur. Adopting 2.5G LAN provides a 2.5 GbE network connection, with transfer speed at least 2 times faster than normal 1 GbE networking, perfectly designed for gamers with the ultimate online gaming experience. Supports multi-Gig (10/100/1000/2500Mbps) RJ-45 Ethernet.
With GIGABYTE Q-Flash Plus, you don’t need to install CPU, memory, and graphics card or enter the BIOS menu to flash BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) to a USB flash drive, press the dedicated Q-Flash Plus button and you’re good to go.
