Zitat von Lost_N_BIOS im Beitrag #10
Yes, I see that now with your images, about the AMIBCP comment. Very weird how this is setup.

restricted to 1.125v with the offset only pushing it to 1.20v and no higher << What is this limitation, I thought you couldn't go any higher than 1.3x in the BIOS?

I will dig into the setup in assembly and see if I can find what differentiates the CPU's and this voltage selection limitation, but no promises as I'm not great at assembly and this is not something I know how to recognize either.
@CodeRush could possibly help if he's around. Maybe @Mov AX, 0xDEAD @lordkag @dsanke @revlaay @svarmod @_haru @ket @Blossomcrown could offer some assembly skills or thoughts on this to help me locate it.
A few others I can't think of know assembly and BIOS modding here too, if any of you guys could maybe tag someone while you're here I'd appreciate it, thanks

@Lost_N_BIOS you can "cheat" to provide more voltage than the board will technically allow. I do it all the time for HD7900 series vBIOSes and RX vBIOSes. You do this by skewing the VRM signal and sending a higher value than its supposed to be. Primarily you use this approach to compensate for vdroop - a poor mans LLC if you will, but theres nothing stopping you from setting way higer VRM signals that supply a lot more voltage you then either need to just remember what you are actually setting or changing the voltage values to match the new VRM signal values. Do note of course that doing so will naturally raise VRM temps as well as push the VRMs harder shortening their lifespan and you can push the VRMs past their technical limit when doing this so be sure to have the specifications of the VRMs so you know what you can and can't get away with. You can also make most VRMs perform more efficiently by changing the VRM switching frequency but you'll need VRMs that support this.
