Area 51 R2 Overclocking in BIOS (Help Needed with settings)

Hi

I am after some help with BIOS settings with overclocking my R2 Area 51

I have it running stable with an overclock in the AW app at 4.5Ghz on all cores.

am very happy with this but find it all a pain having to reload this every time I reboot, on all my previous systems I have overclocked in BIOS

Just not sure with the MSI AW BIOS Which ones I need to adjust for voltage changes.

Anyone up on required BIOS settings and which are the main voltage adjustment ones (Everything on auto at the moment)

Thank you any help would be appreciated
