Occasional flickering, source unknown... need help finding it.

So, here's my setup:

an i7-2600k (stock)

Asrock Z68 something with 16 GB DDR3 RAM

GTX 1080

2 SSD (one Windows and one Gaming)

Monitor in question: Dell S2716DG (2560x1440 @144Hz with G-Sync @ DisplayPort, 1.8m cable that came with monitor)

Second screen (some random) FullHD 60Hz

 

My problem is some occasional flickering. Not end never much, only ever 0.5 to 1 second or less black screen and every thing is back to normal.

I tried around with the Hz setting which improved it (at 60Hz or bellow there's nothing) and at the intended 144Hz in windows it's pretty much fine. But once I start gaming these issue shows up.

I tried another DP cable I had lying around (which felt cheaper) which got worse, also longer cable got worse as well.

 

I used an GTX 770 before which also was worse.

 

My guess so far is something in the data transfer from PC to the monitor. I understand that 1440p@144Hz is a huge amount of data constantly streamed but the cable that came with the monitor and the gtx 1080 should both be sufficent? 
(Funny fact, the gtx 770 actually wasn't. I couldn't even select 144Hz, only 120Hz wich was a constalt flickering, like someone turning on and of a lightswitch)

 

I don't think it is my cpu or motherboard as they manage even BF1 at around 90fps at max setting (kinda dissappointing with the GTX 1080 but the cpu is 5 years old now, so... old man.) 

144Hz is enabled, also g-sync (which I, granted, have not tried turning of yet, but also kind of don't want to)

 

Does this sound familiar to anyone?

Try turning of XMP on the bios and see if that works.

 

If you're using anything less than Windows 10, try turning off HPET in the bios.

 

EDIT:

 

To add, if you have drivers 375.86, uninstall it and use the previous ones as it is causing issues

Finished Crysis without a discrete GPU,15 FPS average, and a lot of heart

 

How I plan my builds -

Spoiler

For me I start with the "There's no way I'm not gonna spend $1,000 on a system."

Followed by the "Wow I need to buy the OS for a $100!?"

Then "Let's start with the 'best budget GPU' and 'best budget CPU' that actually fits what I think is my budget."

Realizing my budget is a lot less, I work my way to "I think these new games will run on a cheap ass CPU."

Then end with "The new parts launching next year is probably gonna be better and faster for the same price so I'll just buy next year."

I actually use these drivers, installed them just yesterday. So i'll roll back there.

However I had the issue before.

 

I'm not sure what you mean with XMP.

Monitor BIOS (ie. Menu?) doesn't have that option anywhere (there'S barely anything to set up at all)

and motherboard BIOS I also checked, yet nothing (but I can't shake the feeling that this isn't what you meant anyway).

 

I am using Windows 10. :)

XMP is extreme memory profile for Intel unlocked 'K' processors that run on the 'Z' boards.

 

Basically, if your i7 2600 is the 'K' version and your DDR3 is overclocked via XMP in the Bios, try to disable it. There should be an option on it under RAM settings there.

 

If you're using Windows 10 then HPET doesn't matter.

 

How is your system after rolling back the driver?

Hi, I tried around with the settings yesterday for a bit as i had the flickering before the driver update as well, just less frequent. in settings for nvidia, g-sync was set to always on, not just fullscreen, and after i changed that everything worked fine (after rebooting). so gonna check some more today.

 

i looked in my bios for xmp but couln't find anything. just memory clock, which was all set to auto and clockrate at 1600 (that is my ram mhz). maybe asrock uses a different name for xmp?

 

it might still be that the gsync setting was changed by the driver update i think, as i turned it off last time i know.

i am playing wow and i really dont need more than 60 fps for that just eats up power in gpu. at my setting the 1080 idles at around 1300 ish mhz when playing wow. no noise, just 1of 2 fans spinneng :)

 

anyhow, thanks for your sugesstins, i'll reply again if the problem persists.
