I have Asus p8z77-v deluxe with an I7-3770k at 4.6 and what is odd is my voltages. I left bios settings auto with cpu load line calibration set to extreme and it blue screened running prime. So I looked at the voltages and noticed a .04 difference in Core-temp and CPU-Z (Core Voltage-VID). I went back and added a .04 + offset to the V-core and all seems quiet stable, I am at 1.1459v VID per Core Temp and 1.224V per CPU-Z, I am using a Antec i620 cooler with 2 fans in push and pull, The only thing that hurts now is motherboard temp per ASUS AI suit is at 63, which I should be able to live with, I am only using this for media server, occasional games, and dvd ripping/editing. Any comments are appreciated.
