Using 1707 (same as all the other bios revisions tbh) I use these settings 24/7. I'd highly recommend remove bios battery for 15minutes to completely refresh BIOS settings and try again (I've always done this a matter of course as I've found it to be the only REAL way to reset the CMOS)

Most of them settings are stock mate, I try to change as little as possible.
This is 100% MAXIMUM stable on IBT, and runs rock solid for everything.
I can get 4.8Ghz but have to use fixed voltage which I'm not too fond of (I also get the occasional non-boot when powering up, and mouse not being recognised) so decided to stick with a 'measly' (lol) 4.6Ghz for 24/7 use.
Temps don't hit over 62Degrees C highest when IBT Max (custom watercooling though - 280mm Koolance, XSPC Raystorm + GPU Block etc etc - Get on average about 58Degrees C when gaming with
[email protected] and fans throttled to about 80% max (2x140mm))
Got it (the cpu) same time as you if I recall correctly matey!
hth.
