Asus P104-100 4G mining card hack to GTX 1080 possible?

I have bought a cheap ex mining card for 60 usd. The seller already modded the vram to 8Gb with bios (the 4G card mod to 8G is very common for this mining series). I can game with a modded asian driver but still limited performance because of the low 4x pcie mode.


The PCB is the same as the Asus GTX1080 Turbo. Vram is GDDR5X 8x1GB (from Micron spec pdf)

Is there an unlocked bios for this card?

First i need to fix the pcie lanes.

It is pcie 16x physically (all traces are good, and there is enough smd capacitor on the lines) so i think it is just bios limited.

I don't care if the outputs not working.

I have Ch341a programmer just don't know that bios to use on this card. It is indeed a GTX1080 turbo, and i think it is the full GP104 GPU (according to Asus pdf spec).

This is a fun project, i have another card for gaming (Intel A770 16Gb) so it is no big deal if the card is dies in the process.
