I suggest you flash your bios again. Reset everything to default before you flash. Matter of fact clear CMOS too. And use the flash back method instead of bios or OS.Also no idea what bios you're on but 1701 should work well enough.
I see. So if you leave Pstate0 VID as default then you need to set negative offset to even get to 1.44v?Try changing it back to Pstate0 VID to default, set voltage to offset and take a picture after restart.
I am fairly conservative with voltages myself but I don't think going up to 1.4v (without using LLC) is bad. Try 1.38v and if that doesn't work, you can probably get to 3.8ghz with a lot lower volts as well.
