4770K Cannot get prime 95 stable

Bios settings in details bellow. I'm running at 4.2Ghz, quite works for everyday gaming and tasks, no BSODS so far, still fails on prime95 on start or about 5 mins later. Any help tweaking these would be appreciated, im burning my head off and can't do it.

on a side note, It would boot even a 4.4ghz @ 1.25 Vcore, but prime is a no go...

Specs:
I7 4770K
MSI Z87-G45
2X8 RAM CMD16GX3M2A2400C10 CORSAIR PLATINUM (10-12-12-31 @ 1.65v - 2400Mhz)
MSI GTX 980
Cosair 650TX PSU
 


Kinda got the ring up to 1.140 as shown, heard that 1.2 should be the max safe, not so sure...
