Overclocking voltage caused CPU to brick?

[Epsile]

My friend and I were trying overclocking his CPU past 4.7, and we were messing with the voltage offset because I had heard that it helps to up the voltage. We decided +0.05 would be best because it isn’t a lot (or so we thought), and suddenly the computer blue screened. When we tried booting into windows again, it would stagnate at the same loading ring forever. After a while of messing with the system recovery options, we then decided to restore default UEFI settings to no avail. We then tried installing windows on an external HDD to try and solve the problem and boot from there, but with yet no result.

Specs:

i7-6700K

ASRock Z270 Extreme 4

16 GB DDR4 2133 MHz RAM

Corsair RX750 PSU (i think)

XFury 256 GB SSD

1 TB 7200 RPM HDD

GTX 1080 6 GB (Founders Edition)

Corsair H60 Rad.

Error codes:

0x80300024

CLOCK_WATCHDOG_TIMEOUT

WHEA_UNCORRECTABLE_ERROR

0xc0000225

so what voltage were you at? over 1.4V is danger terretory but CPUs dont tend to insta die before ~1.7V or so but im a bit unsure on 6th gen voltages tbh

You'll just need to reset the CMOS and get rid of the bad OC.

 

1. Turn to PC off completely and unplug it from the wall as well.

2. Take the little jumper off of these pins here:

and put it on the 2nd and 3rd pin for about 5-10 seconds.

 

3. Put the jumper back on the 1st and 2nd pins

    then plug the PC back in and turn it on.

Turns out he fixed it by clearing his C drive, but thank you regardless! I’m sure he’ll use this if he OC’s again.
