2-No voltage limit, pushing limit from 1,093v to 1,2v

Disadvantages:
1-Loosing of a displayport connexion on some card
2-No tdp monitoring and loosing of some temperature monitoring( No ICX monitoring on GPU-Z but already work on Precision XOC et X1)
3-Black screen on google chrome(Can be solved by replace the shortcut target with "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -disable-gpu")

To overclock your GPU with this XOC bios, Voltage/Frequency curve must be used.
Without voltage/tdp limitation the card will reach the highest frequency and tension point of the curve (2000Mhz at 1,2v for the stock curve).

Open MSI afterburner and open the the window of voltage/frequency curve.

Then we have that :

To apply a frequency at a target voltage, select a voltage point on the curve then increase the frequency offset:

After setting the offset, validate with :

After applying the offset, the curve should be auto-adjusted to a predefined frequency, you must reset it at +-13Mhz:

There is it, you must find your best frequency/voltage combo for your graphic card.

The repeat the step to the limit of your card.
