uncommon "unlocking" request for HP DV6 sp54724.exe

[DlRK]

Hi to all that are willing to help, and are obviously more skilled with bios editing than me! :-)

I'd originally like a bios mod that "unlocks" the voltage adjustment for the inbuild dedicated GPU (HD 6750m) of my HP DV6-6110sg. But i guess there's not even a slight chance that this is possible by editing the bios. (the usual suspects to adjust the voltage, like msi afterburner, can't read out the voltages from the gpu-bios, because it's incorporated into the main bios)

So I'd rather have someone to look into the bios, if there's a possibillity to raise the standart voltage of the 6750m gpu (1.000v) to a fixed higher value (like 1.075v). Afaik there could be multiple entrys of the same voltage (because of the different power states, like 3D/UVD/overdrive), and other voltages from the second gpu, the processor-inbuild HD 6520g (which ought to have 1.035v under load).

So is it even possible to locate and alter those values? Or would that be like searching the needle in the haystack? :-)
The bios is the F.21 insyde bios from HP: http://ftp.hp.com/pub/softpaq/sp54501-55000/sp54724.exe

Thanks in advance!
