ASRock
ATX board for Intel Core Ultra Series 2 with DDR5 up to 8666 MT/s, PCIe 5.0 x16, Gen5 M.2 at 128 Gb/s, Dragon RTL8125BG LAN and WiFi 7
The ASRock B860 Rock WiFi 7 is a new ATX motherboard built around the Intel B860 chipset for Intel Core Ultra Series 2 processors. It fits the LGA 1851 socket and provides a foundation for work, study and gaming with a clean, modern design.
This board suits users who plan to push DDR5 memory speeds with Intel XMP 3.0 profiles across four slots for up to 256 GB capacity. Those needing ECC memory support or a smaller form factor should look at alternatives.
The CPU-connected M.2 slot (M2_1) runs at Gen5x4 (128 Gb/s) for type 2280 drives, delivering the highest storage bandwidth available on this platform. If a single Gen5 M.2 device is the primary storage goal, this slot is the deciding specification.

The Dr.MOS power stages and Hi-Density connectors are solid-state components with no moving parts; no scheduled maintenance or periodic replacement is required.
The 6-layer PCB and Dr.MOS design keep VRM temperatures low, so the practical ceiling is the CPU's own thermal or power limit rather than the motherboard's delivery capability.
With no onboard fans, the motherboard adds zero acoustic noise; VRM heat stays modest thanks to the 6-layer PCB and Dr.MOS efficiency, and idle power overhead is minimal.
