Socket LGA 1851 platform for Intel Core Ultra

This ATX motherboard uses the Intel B860 chipset to support Intel Core Ultra Processors (Series 2). It provides a 12 Duet Rail power system with 60A smart power stages and dual 8‑pin CPU connectors for stable delivery under load. The board targets builders who want modern connectivity and straightforward assembly.

DDR5 9200 MT/s OC with four slots and Gen5 M.2

Four 288‑pin slots accept up to 256GB of DDR5 memory running at 9200+ MT/s when overclocked. One PCIe 5.0 x16 slot and one M.2 socket wired for PCIe 5.0 x4 give headroom for the fastest graphics cards and SSDs. Two additional M.2 sockets run at PCIe 4.0 x4 and four SATA 6Gb/s ports handle extra storage.

Wi‑Fi 7 and 5G LAN with extended heatsink cooling

Killer Wi‑Fi 7 BE1750x uses a 320MHz channel for up to 5.8Gbps throughput, 2.4 times faster than Wi‑Fi 6/6E. A Killer E5000B controller provides 5Gbps wired Ethernet while Bluetooth 5.4 handles peripherals. Extended heatsinks, 7W/mK MOSFET pads and the tool‑less EZ M.2 Shield Frozr II keep thermals in check during sustained workloads.

Questions sur cet article

Will my DDR5-9200+ MT/s OC memory kits run at rated speed on this board with the LGA 1851 socket?

The board supports DDR5 up to 9200+ MT/s overclocked across four 288-pin slots in dual-channel mode, with a maximum capacity of 256 GB.

How can I confirm Wi-Fi 7 and 5 Gbps LAN are active after building the system?

In Device Manager the Killer BE1750x adapter should show Wi-Fi 7 with 320 MHz channel width, and the Killer E5000B LAN should report a 5 Gbps link speed.

Does the box include the EZ M.2 Shield Frozr II cooler and Wi-Fi 7 antennas, or must I buy them separately?

The EZ M.2 Shield Frozr II is integrated on the board for tool-less M.2 installation, and Wi-Fi 7 antennas are supplied in the box; no separate purchase is needed for either.
