B150 boards typically need a BIOS update before using 7th Gen CPUs. Chances are pretty good the motherboard doesn't have the latest BIOS to support.
Options:
1. Buy the cheapest 6th Gen chip you can afford and flash the BIOS - about $50 (https://pcpartpicker.com/product/kxs8TW/intel-cpu-bx80662g3900)
2. Talk to a local PC store, they would likely flash it for you for a nominal fee
3. Return it and buy a B250 / H270 board.
FWIW, 3000MHz is a bit wasted on a B chipset. B150 is limited to 2133MHz and B250 increases that to 2400MHz.
