[Request] Bios mod for a compact chinese PC to run VRtdc higher

Hi guys, you seem to have a nice place here

Now my request. I have a chinese compact PC, with a i7 6785R cpu. The problem however is, that it is cut to 45W. VRtdc (Voltage Regulator thermal design current) is triggered when i run all cores.
When i run 3d-games on it, it draws up to 100W tho. But i would like to run it to spec at 65W or even a value i set.

What tool do i need to get the bios from that computer to give it to you? The chinese manufacturer has no bios downloads for that computer. Even contacting was pointless.

They also sell other CPUs in that computer which have the 45 TDP, this is where the 45W limit comes from i think.
Long and short term boost durations can be set in the bios, but to no effect.

It would also be nice to run DDR3 2133 Memory in it. It uses notebook memory.

I hope you can help me.

Thanks in advance guys.
