System detected other motherboard

Hi, i got a problem. A few programs detected my MOBO as a B150 but i have h110m. Could it be any problem? How to repair that?
In CPU-Z my CPU is jumping from 0,7 ghz to 3,7ghz is it normal?
In RAM section i got 4 slots (my rams are on first and 3th one) but i have only 2 on my mobo. Is it normal? Im beginner in PC building so it is hard for me.
Specs:
i3-6100
Msi h110m pro-vd
2x8GB DDR4 Kingston Hyperx fury CL 14 2133
Vero L1 600w
Sapphire RX 580 4gb nitro +
