Hi, the problem I'm having seems to only happen occasionally (usually a while after PC being turned on). In fullscreen videos and browser tabs the screen will flicker black when anything is moved, e.g. watching a video and i move the mouse over the pause button or changing headset volume, this movement seems to cause blackouts that recover a couple milliseconds after. I have just re installed my video drivers but its not been long enough for anything to happen.

When this happens my only option is to restart the system, Windows key + Ctrl + Shift + B does not work. As the title states this has only started since I overclocked my CPU. I returned BIOS to default and didn't have the same problem, although only ran it like this for a few hours before returning to my OC. It's possible it was coincidence

If anybody has suggestions I'd love to hear, Thank you.

System Specs:

MB - Asus Z170 Pro Gaming
CPU - i7 6700k OC 4.5ghz
CPU Cooler - Corsair H100i V2
GPU - Asus GTX 1080 STRIX A8G
RAM - 2x 8GB Corsair Vengence LPX 3000mhz (Currently stock 2133mhz to try solve instability)
PSU - Corsair RM650i
 
It's not coincidence. It's unstable. What is your core voltage at currently? Uncore voltage?

Offset and adaptive voltage settings?

Is this a manual overclock or are you using an automatic utility?

What are your full load core temps? What have you used to put the CPU at full stress and what are you using to monitor core clocks and thermal sensor readings?

Core voltage is 1.300 set to adaptive with no offset. CPU-Z voltage goes up to 1.335 which doesn't concern me.

Manual overclock to 4.5 ghz, RAM was at 3000mhz however I had stability issues earlier this year (different symptoms though) so I decided to keep it at stock 2133 with 1.350 voltage set by XMP.

Not at PC so can't tell you the values on CAS, RAS etc.

Stressed with AIDA 64 and done some other more realistic stress testing like realbench, cinebench and 3d mark Time Spy and Time Spy extreme (passed with better CPU score and overall score for all)

Temps topped out at 70C

Sorry I missed a lot of information in my original post was in a rush

Still doing it. Went to stock settings and it's continuing so I'm going to reinstall the Nvidia drivers. It's possibly corrupted
