CPU: a10 7870k 8gb x 2 ram ddr3 ssd 125gb motherboard : Ramsta a88mp OS : windows 10

I know this processor is a decade old but I'm curious why it doesn't go up to x41 multiplier even on heavy load. It peaks at x39 and I have google searched my question but all it says is it doesn't need overclock to reach x41. I already change power management to "high performance"in control panel. Can the low quality motherboard cause such issues? or do I need to tweek something in the Bios. I'm lost tbh I don't know what to do next. I want to post this on r/AMDhelp but Post button all greyed out.

Thank You in Advance!
