Are you implying that the actual voltage is the one given by the dyn_nominal variable? From what I've read that's not the case, dyn_nominal is the voltage at which SmartReflex starts a new round of calibration and lowers from there if possible. The idea is that dyn_nominal is a stable voltage for that particular chip in all conditions, including after deterioration due to aging and at high temperature.

I can't actually set the voltage lower than the default calib voltage, so if I'm right undervolting is not possible, in fact, at least not with the current method.

It all depends on silicon everyone is going to have different results it's like a lottery of who has the better silicon chip!

Sorry I meant that if I try to set the voltage lower than the default (1.1875 V for me) it doesn't have any effect, the voltage will stay at the default. I think it's the same issue discussed here. Stability at a low voltage would be an other matter.

I've been using the module for a few days now. I can say that it's well worth a donation.

In my experience, foreign currency conversion fees are normally along the lines of 3%, not 3 EUR. On a donation of a few euros, the fee shouldn't be noticeable.

(I wonder if fears of currency conversion fees are the reason INCEPTION donations have been rather limited...)

opps sorry, I don't know why I wrote that. I am getting mixed up. I updated the previous post you're referring to. You're correct on both things - *something* is blocking us from lowering the voltage further, and we probably shouldn't anyways. I'll try and fix it though, I must have some other bugs in the module I didn't realize. Thanks!

Running at 1300mhz and 1325000 voltage for awhile now, battery consumption is higher, but things are so quick. I'm still working on finding the sweet spot.

My sweet spot is 1300 mhz with the default voltage, 1375000, battery consumption is about the same for me and everything is so smooth and quick! Just did a minimal stress test of 25apps which included angry bird with magic and actioncam. It was so smooth switching between everything no lag in site.
