Is my CPU compatible with my motherboard?

[haydencf3]

I just bought a the Asus - STRIX B250H Gaming ATX LGA1151 Motherboard. I was planning on buying the i5 7600k CPU, but decided I would buy a i3 8350k because it is slightly faster and less money. The CPU is a LGA1151 socket like the motherboard, but PC part picker says they are not compatible. Does anyone know why?

The 8th series CPUs work only with the 300 Intel series boards. So not compatible with your board.

To be exact, 8th gen CPU use slightly modified 1151 socket. Size and number of pins are same with 6th and 7th gen, but pin map is different, and that's why 6th and 7th gen motherboards don't work with 8th gen CPU.

To expand:

Intel used the same socket, but re-arranged some of the pins to increase the power delivery to the new 6-core CPUs as well as possible future CPUs.

Despite the i3-8350k only being a quad core, they did not make it backwards compatible so that they wouldn't have to compromise or create an even more confusing situation. (Though they really should have marketed this as LGA1151-v2 or something.)
