B660M Gaming X AX DDR4 rev 1.1

This micro-ATX motherboard uses the Intel B660 chipset and LGA 1700 socket for 12th and 13th Gen Core, Pentium Gold and Celeron processors. It targets builders who want a compact board with Wi-Fi 6E, 2.5GbE LAN and dual M.2 slots for NVME SSDs. Four DDR4 DIMM slots support up to 128 GB in dual-channel mode.

Power delivery and connectivity

An 8+1+1 hybrid digital VRM with premium chokes and capacitors feeds the CPU through an 8-pin solid-pin connector. Fully covered VRM heatsinks and an M.2 thermal guard manage heat. Rear I/O includes USB 3.2 Gen2 Type-C, HDMI 2.1, Intel Wi-Fi 6E AX211 with Bluetooth 5.2, 2.5GbE LAN and 7.1-channel audio with noise guard.

Compatibility checklist

Verify your CPU has integrated graphics if you plan to use the HDMI port. Ensure the case fits micro-ATX and has clearance for the VRM heatsink assembly. Confirm the power supply provides an 8-pin CPU connector. Check that your DDR4 modules match the board's validated speeds up to 4400 OC.

Questions about this item

What PCIe version does the primary M.2 slot use, and what speed does that cap the drive at?

The CPU-connected M2A_CPU slot runs PCIe 4.0 x4, so a compatible NVME SSD is limited to PCIe 4.0 x4 throughput.

What clearance does the VRM heatsink and M.2 Thermal Guard need for a CPU cooler?

The board uses a fully covered thermal design with high-coverage VRM MOSFET heatsinks and an M.2 Thermal Guard; allow enough height for your cooler to clear those components.

How do I update the BIOS with Q-Flash Plus, and which step is commonly missed?

Place the BIOS file on a FAT32 USB drive, plug it into the dedicated Q-Flash Plus port, press the Q-Flash Plus button with system power off but the PSU switched on; the step often missed is keeping the PSU on while the board is otherwise unpowered.
