Hi.
I put together my new pc today after giving my g3258 oc system to my parents.

I was really hoping to overclock the i5 6400 by upgrading the bios and changing the block ratio but every time I boot it just goes back to 100!

Has anyone achieved a stable non-k overclock using the MSI z170 A Pro?

I'm using E7971IMS.191 as the bios, not sure if there is a better one?

Any help appreciated
