Yep, you are absolutely correct about the pins, thank you!

The screenshots of the working EVC2 are attached.

One more question before any experiments - I've heard that for 2080\2080 Ti it may be required to short SCL & SDA during the boot process to unlock the voltage control ability - it this action still required with current EVC2SE revision and EVC2 1.0.1.2 software?

Ok great. Yes you can see the "SMBus Lock" option reads "Locked". You can check "Lock bus" + Apply under I2C1 to prevent this at power on. Make sure to fully power off your system to reset this status before trying that. The option should read "Not yet unlocked", after which you can change it to "Unlocked".

Works great, the bus is unlocked! So, I presume that now I have the opportunity to manipulate the voltage a bit.

A few other questions, if you please:

  • In case of the constant running the EVC2 with "Lock bus" checked, will the SMBus be unlocked every time after reboot?
  • The resulting voltage is the one at the current point of V\F curve in Afterburner + the voltage offset LCS0 in EVC2?
  • Is it possible to use negative offset?
  • Why the checkboxes are still disabled after unlocking the bus? May there be any reason and way to enable them?
  • Checkbox "over-voltage" is not set, but "under-voltage" is checked - does this mean that only under-voltage is allowed?

Apologies for such a curiosity, I just would like to understand these nuances and how to use the tool properly. If I missed some documentation, please point me to the right direction 🙂

As always - thanks for the helpful advices and for such a great experience.
