My chip gets to 5.5+ using mostly auto settings, other than the basic voltages that I manipulate. BCLK just barely over 100, it doesn't like std OC with the 125 BCLK so IIRC, I start with the gamers OC, then make all the cores the same and enable on screen core adjustments. Boot into the 4s and use software to raise the cores and voltages... slowly. This is on SS
My chip seems to like HT on and actually runs faster with HT on. ?? Mine is a 3960X so I don't know how much if any that changes things to your chip?
BTW, it's CPU Tweakers Paradise, etc

Damn BIOS gives me a headache
Unless I'm missing it, the ROG connect won't let you raise cores, which is why I use Turbo V
