I don't understand how you are getting .7 out of the VRMs on firmware 0.94. I'm running 0.94 and have .9+v and don't see .7 unless I run 0.95.
I believe you have to do the secret handshake to get it to switch back to high volts once you go to .95+

It might need a hard reset or perhaps going to an earlier firmware first.. i kinda forget myself the surefire way of switching them back
I see, you tried 0.96 and then 0.94 gave you the .7 volt VRM output voltage?
Then I'll stick where I am until after the next diff increase and likely beyond that.
