Need Guidance: EVGA RTX 3090 Kingpin w/ EVC2SX

Hey there! I realize there's a Classified Tool and that I can adjust voltages with it, but I'd also like to be able to monitor and perhaps adjust settings on my 3090 Kingpin via a laptop while testing.

I am at a loss about how to use the software for the EVC2SX. How do I detect and monitor the proper data in real time? How can I tweak parameters?

I installed the latest firmware and software without issue. When I choose "Find Devices" with the EVBOT output's SCL, SDA, and GND pins connected to I2C1 it finds the device at address 1D (and I verified that if I swap SCL and SDA, it doesn't find the device). 

Then I hit a wall. I'm not sure what else I need to do in order to use the EVC2SX! I tried to manually add IR3595 but wasn't really sure what I was doing, so I just stopped there before messing anything up.

Any help would appreciated. Thank you!

(Note that I'm also asking this exact question in Discord now that the invite worked)


Based on the Discord conversation:

  • Evbot header connects to a microcontroller at address 1D, not directly to the voltage regulators which means EVC2 can't talk to them.
  • There's a JSMB2 header near the voltage regulators that probably connect directly to them. Soldering to that header would most likely give direct control.

I will try to

test and confirm this headers functionality by weeks end.
