LGA 1700 Micro ATX board for DDR4 systems

The ASUS Pro B660M-C D4-CSM is an Intel B660 motherboard built for LGA 1700 processors. It supports up to 128GB of DDR4 memory in a compact Micro ATX layout. The board ships with a chassis I/O back panel and a SATA cable.

Suits builds using 128GB DDR4 on B660

This board fits builders who need a Micro ATX form factor with the Intel B660 chipset and full 128GB DDR4 capacity. Buyers requiring a larger ATX footprint or a different chipset feature set should look at alternative form factors or chipsets.

128GB maximum DDR4 capacity

The single specification that determines fit is the 128GB DDR4 memory ceiling. If the planned system demands more memory than this limit, the board cannot meet the requirement.

Questions about this item

What does the 128GB maximum memory mean for a real build?

The board can hold up to 128GB of DDR4 across its DIMM slots, letting you run large workloads or many virtual machines without hitting a capacity ceiling.

What does the LGA 1700 socket and B660 chipset combination determine in practice?

The LGA 1700 socket physically fits the processor, while the B660 chipset defines the feature set and lane allocation available to that processor once installed.

What does the Micro ATX form factor require for mounting?

A Micro ATX case or larger with matching standoff holes and an I/O shield cut-out will accommodate the board; the package includes the rear I/O panel for that purpose.
