- Supports Intel Core Ultra Series 2 processors on LGA 1851 socket
- 10+1+1+1+1 Dr.MOS power phases deliver stable CPU current
- Four DDR5 slots up to 8666+(OC) with XMP 3.0 support
- PCIe 5.0 x16 and M.2 Gen5x4 128 Gb/s for fastest graphics and storage
- 1 channel Realtek ALC897 audio with Nahimic enhancement
Socket and processor support
The board uses the LGA 1851 socket for Intel Core Ultra Series 2 processors. The Intel B860 chipset provides the platform foundation. Four DDR5 slots accept up to 256 GB in dual-channel mode.
Memory capacity and speed limits
Memory runs up to 8666 MT/s with XMP 3.0 profiles on non-ECC unbuffered DIMMs. The 256 GB ceiling is reached only when all four slots are populated with high-density modules. Two slots leave headroom for later expansion.
Expansion slots and onboard audio
One PCIe 5.0 x16 slot and one PCIe 4.0 x4 slot handle graphics and add-in cards. Three M.2 sockets support 2280 drives, with the top slot wired for Gen5 x4 speeds. Realtek ALC897 delivers 7.1-channel audio with Nahimic software.
