ASROCK B660 Pro RS DDR4 Intel Motherboard

The ASRock B660 Pro RS is a full-size ATX motherboard (30.5 cm × 24.4 cm) built on Intel's B660 chipset and designed for 12th Generation Intel Core processors using the LGA1700 socket. It supports Intel Hybrid Technology and Intel Turbo Boost Max 3.0 Technology, making it a capable platform for mainstream desktop builders who want a reliable, feature-rich foundation without moving to a premium chipset. Memory support centres on four DDR4 DIMM slots running in dual-channel configuration, with native DDR4 3200 speeds and XMP 2.0 profiles that allow overclocking up to 5333+ MHz (OC). Maximum installed capacity reaches 128 GB, and ECC UDIMM modules are accepted in non-ECC mode, giving the board a degree of workstation flexibility. Storage connectivity is a standout area. Two Hyper M.2 sockets (M2_1 and M2_3) run at PCIe Gen 4×4, delivering up to 64 Gb/s each, while a third M.2 socket (M2_2) supports both PCIe Gen3×2 and SATA3. Four SATA3 6.0 Gb/s connectors round out the storage options, and RAID 0, 1, 5, and 10 are supported for SATA arrays. All occupied M.2 slots benefit from ASRock's Full Coverage M.2 Heatsink to manage thermal output under sustained loads. Expansion slots include one PCIe 4.0 ×16 slot (CPU-direct) reinforced by ASRock's Steel Slot design, a second PCIe 3.0 ×16 slot (running at ×4 via chipset), and two PCIe 3.0 ×1 slots. An M.2 Key-E socket accepts optional 2230 Wi-Fi or Bluetooth modules, including Intel CNVi cards. Display output leverages Intel Xe Graphics (Gen 12) through an HDMI 2.1 TMDS-compatible port (up to 4K/60 Hz) and a DisplayPort 1.4 port with DSC support (up to 8K/60 Hz compressed). USB connectivity spans nine USB 3.2 Gen1 ports (four rear, four front headers, one front Type-C header) and four USB 2.0 ports (two rear, two front header). Rear I/O also includes a PS/2 port, Gigabit LAN via Intel I219V, and a BIOS Flashback button for no-CPU firmware updates. Audio is handled by the Realtek ALC897 codec with 7.1-channel HD output and Nahimic Audio software. RGB customisation is available through one 12 V RGB header (up to 36 W strip) and three 5 V addressable LED headers (up to 15 W strip total), managed via ASRock Polychrome SYNC. Fan management covers seven headers in total, including a dedicated CPU/Water Pump connector and five Chassis/Water Pump connectors with Smart Fan Speed Control.
