Questions about this item

What maximum DDR4 capacity does the Intel B660 chipset on this board allow?

The Intel B660 chipset on this ASUS PRIME B660M-A D4 supports up to 128GB of DDR4 memory across its four slots.

Which case form factor and mounting pattern does this Micro ATX motherboard require?

It uses the Micro ATX form factor, so it fits any chassis with matching Micro ATX or larger ATX mounting holes and I/O shield cut-out.

How is the CPU installed into the LGA 1700 socket, and what step do builders often miss?

Lift the socket lever, align the processor triangle with the socket corner, lower the CPU gently, close the lever, then secure the retention plate — many forget to engage the retention plate after the lever.
