Iam here because ive got some old PCs from work and they got accidently a bios-update and lost the ability to undervolt the cpu. First i tried to rollback to an older version but the vendor does make it really hard, then i just picked another old PC and a bios-programmer and solved it this way. Right now one of the old PCs is my trashy-gaming-rig and rolls with a old 6700k, but i cant set multipliers with the oem-bios, so i was thinking about setting it in in the bios by modding it… i dont know… see ya
