ASUS EX-B660M-V5 DDR4 Intel Motherboard

The ASUS EX-B660M-V5 DDR4 is a Micro-ATX motherboard built on Intel's B660 chipset, designed for 12th Generation Intel Core, Pentium Gold, and Celeron processors using the LGA1700 socket. It is part of ASUS's Expedition series, which targets high-uptime environments such as internet cafes, small offices, and community computing labs that demand continuous, dependable operation. Memory support covers two DIMM slots with a maximum capacity of 64 GB of DDR4 non-ECC unbuffered RAM running in dual-channel configuration. Supported speeds span from 2133 MHz up to 5333 MHz (OC), and the board is compatible with Intel Extreme Memory Profile (XMP) for straightforward performance tuning without manual voltage adjustment. Storage flexibility is provided by two M.2 Key-M slots, both supporting type 2242, 2260, and 2280 drives with PCIe 4.0 x4 mode, complemented by four SATA 6 Gb/s ports. Intel Rapid Storage Technology enables SATA RAID 0/1/5/10 configurations for users needing redundancy or striped performance. Display output on the rear panel includes one D-Sub port and one HDMI port rated for 4K at 60 Hz per HDMI 2.1 specification, making the board suitable for builds using Intel integrated graphics. Connectivity is handled by a Realtek 1 Gb Ethernet port with ASUS LANGuard hardware-level surge and EMI protection. Audio is delivered via a Realtek 7.1 surround sound HD Audio codec supporting up to 24-bit/192 kHz playback, with dedicated audio PCB layers and shielding to reduce interference. USB ports total 12 across front and rear: six on the rear panel (four USB 3.2 Gen 1 Type-A and two USB 2.0 Type-A) and six via internal headers. Protection features under ASUS 5X Protection III include DIGI+ VRM, LANGuard, USBGuard (rated for 120% higher overvoltage tolerance than standard), SafeSlot Core+ reinforced PCIe x16 slot, and a luminous anti-moisture coating. The 8-pin ProCool connector uses solid pins for improved current handling. The UEFI AMI BIOS (128 Mb Flash ROM) includes Lightning Boot for faster POST in diskless and cloud-PC environments. The board carries a 3-year manufacturer warranty.
