G3258 & GA-H97M-HD3 bios doesn't allow vcore over 1.2v

[Pota]

I have a GA-H97M-HD3 with the latest bios and a G3258 clocked at 4.2Ghz @ 1.2v. I'd like to increase the vcore, but it seems 1.2 vid is maximum allowed in the BIOS. Other 1150 gigabyte motherboards do not impose such a ridiculous limit. Does anyone know how I can overcome this limitation? Thanks
