LGA 1700 Micro ATX Board for 12th Gen Builds

This MSI B660M board uses the LGA 1700 socket and supports 12th generation Intel Core, Pentium and Celeron processors. The Micro ATX form factor fits smaller cases while keeping four SATA 6Gb/s ports. Two DDR4 slots accept up to 64 GB of memory running at JEDEC speeds of 2133, 2666, 2933 or 3200 MHz.

Check Socket, Memory Slots and SATA Needs

Verify your CPU uses the LGA 1700 package and belongs to the 12th generation line before ordering. The board provides only two DDR4 slots, so builders needing four populated DIMMs should look elsewhere. Confirm that four SATA 6Gb/s ports cover your storage count and note that SATA port 7 becomes unavailable when a SATA M.2 drive occupies the M2_1 slot.

Realtek Audio and SATA Trade-off Explained

The integrated Realtek ALC892/ALC897 codec delivers 7.1-channel high definition audio without extra hardware. The only bundled feature that changes connectivity is the M2_1 slot shared with SATA7; populating it with a SATA M.2 SSD disables that SATA port. No other accessories or software bundles alter the board’s core interfaces.

Questions about this item

Does the board come with any memory modules or do I need to buy DDR4 sticks separately?

No memory modules are included; you must purchase DDR4 DIMMs that run at 2133 2666 2933 or 3200 MHz by JEDEC.

Which DDR4 capacity should I choose for the two slots?

Each slot accepts up to 32 GB for a total of 64 GB; pick a matched kit that matches the 2133 2666 2933 3200 MHz JEDEC speeds.

What does the 4000 MHz DDR4 rating mean once the system is running?

4000 MHz is the overclock ceiling; standard operation will run at 2133 2666 2933 or 3200 MHz unless you enable XMP in BIOS.
