Black lines briefly

[chickabumpbump]

Hi All

I am having, oddly, once per PC session. So I turn it on web browse or game on Total warhammer 3 and at some point during the session I will have a VERY VERY brief like single frame flicker of black lines going horizontal all over the screen.

It has happened on this game but I havent played any others lately and when just on google chrome. It wont happen more than once and happens a while into whatever I am doing.

I have a Ryzen 5800X3D, 4070 Super FE, a gigabyte M28U and 850 power supply using Display port, I have changed the port to test this.

Any ideas, should I be worried about something more serious!?

Most of the case DP/HDMI problem, i had this problem, i thought my GPU artifact already, after change cable all fine, your GPU is brand new? No OC right

I got it day one of release so yeah newish I guess. Doesnt overclock.

I changed the cable but haven’t tested it yet. It’s annoying as I can’t replicate the issue

Try forcing the GPU into either PCIE 3.0 or 4.0 Mode via th3 BIOS. Don't leave it on Auto.

One thing I can say about HDMI/DP cables that could randomly cause this issue, get those cables well away from any Pier Cables. Do not allow them to touch or be within close proximity of one another.

Which Monitor are you using?

Some Monitors are pre OCed out of the box. Such as some 165Hz screens actually just being a pre-OCed 144Hz screen and thus might be unstable sometimes at 165Hz

Gigabyte m28u

I told the Nvidia panel to do 120 max and windows too

Set Background FPS to either 30 or 60
Set Max FPS (this is for a 3D app that's in focus) set to 60, or set to half your refresh rate. So for example if using 144Hz Display, set this to 72.

Then enable FreeSync/GSync; if you lack this, then try setting Vertical Sync to either Fast or Adaptive.
