Hi,

There's always a chance some motherboard has undocumented jumper or dip switch settings.

On the EP-MVP3G the voltage is set via a DIP switch. The manual only lists a few. I figured how the <2.0V voltages by testing some of the voltages, but not all, and looking at the CPU voltage in BIOS. On my unit, it always reports ~0.02V less than what has been set. DISCLAIMER: I can not be sure I haven't made a mistake. I have no idea if the BIOS actually reports the right voltages or not. I do not have a "high-voltage" CPU to test >2.0V voltages.

But here's how it seems to work:

• Turns out the SW1-5 sets the "baseline" to 1.3(off) or 2.0(on).
• If the "baseline" is 1.3V, then the other switches (1-4) increment the voltage by .05V, .1V, .2V or .4V, respectively.
• If the "baseline" is 2.0V, then the other switches (1-4) increment the voltage by .1V, .2V, .4V or .8V, respectively.

So, you can set any voltage from 1.3V - 2.1V in 0.05V increments or 2.1V to 3.5V(?) in 0.1V increments!

See the attached file. The green/bolded are documented in the manual, the bold/italic have been tested by me. THEN AGAIN: I take no responsibility in any possible mistakes I may have made nor if you fry your hardware. You try these at your own risk. But at least it was a nice little test to tinker with, maybe someone finds this helpful 😀
