OK..man...here it goes....
First of all lets down clock your system to the most stable basic level. All ready your vCore seems high to me.
1. Go to the BIOS and disable all power saving options. (You will have to research this, I do not know that much about ASUS). This is very important.
2. Lower the vCore to 1.2V and commit the changes.
3. Get to the desktop, and using CPU-Z see if the new vCore is reflected.
4. Run the stability test using ReatTEMP with Prime95(2x threads).
Keep lowering vCore in decrements of 0.1V till you get instability. Repeat 1--->4.
Once you have a stable system with the lowest possible vCore, run a FULL Furmark Benchmark or OCCT burn test. System should HOLD.
If it is stable, post a screenshot of (4).
This will give us the base level benchmark for your system. And will also get your hands dirty, for initial OCing.
Post this we move to the 'actual OC'.
Best of luck.
