Socket & platform

The ASUS PRIME B660M-A D4 is a micro-ATX motherboard built around the Intel B660 chipset and the LGA 1700 socket. It supports 12th and 13th Gen Intel Core, Pentium Gold and Celeron processors, with a BIOS update potentially needed for 13th Gen CPUs. The board targets builders who want a compact platform for current-generation Intel desktop chips.

Cooling & power

Comprehensive cooling includes a VRM heatsink, an M.2 heatsink and a PCH heatsink paired with hybrid fan headers managed by Fan Xpert 2+. These components dissipate heat from the power delivery and storage areas during normal operation. The layout keeps temperatures in check without requiring exotic airflow solutions.

Memory capacity

Four 288-pin DDR4 slots accept up to 128 GB in dual-channel mode, with supported speeds ranging from 2133 MT/s to 5333 MT/s (OC). This ceiling decides whether the board fits a high-capacity workstation build or a mainstream gaming rig. Choose this model when 128 GB is the target.

Questions about this item

Will a 13th Gen Intel Core CPU work straight out of the box?

A BIOS update may be required before the board will boot a 13th Gen processor. Check the ASUS support page for the latest firmware and update instructions.

What DDR4 speeds can I run without manual tuning?

The board defaults to 3200 MHz. Higher frequencies up to 5333 MHz are listed as overclocked profiles and need XMP or manual setup in the BIOS.

How many M.2 SSDs can I install and what lengths do they support?

Two M.2 slots are available, both Key M, accepting 2242, 2260 and 2280 form factors. The first slot runs from the CPU, the second from the chipset.
