I've been using the Mahdi Rom and the dyn.Kernel since i got the Pad, and it works great so far.
With both allowing undervolting of the Pad, i've been wondering why no one posted anything about it so far.
(wanted to read up on that first before i try it myself, heh, a couple of things went wrong with my nexus when i tried that before )
I've gotten very good results with undervolting on a Nexus 4 that has a similar powerhungry chipset (after a lot of trial and error), Battery life effectively doubling (with a few other tweaks).
Also the range of the undervolt (CPU binning) was CPU dependent as i gathered from the Nexus.
dmesg | grep PVS
results in a '1' for me. (yay, slowest)
Is this still relevant for the G Pad, and has anybody undervolted yet?
Post your results if you have any.
