Measured vcore should drop under load. It should be higher at idle. Someone more knowledgeable can give an explanation, but as for the phenomenon, it's normal.

Could be a faulty PSU. Have you monitored your voltage ripple during stress tests? The Antec EA650w is reputedly very high quality, so it may require an RMA if there's much noise on the rails.

I had to put vcore back to 1.4 otherwise it would just drop to 1.296

now it only drops to 1.320

my temps went as high as 75c

It passed 10 runs ibt (does this mean is stable or do I need more runs)?

will this vcore 1.4 wear my cpu out?

B2 or B3 stepping? If it's B2, you should RMA for a B3.
B3 has new beta bioses that have tweaks to LLC.
