Question Strange Behaviour of GigaByte RTX 4080 Super Gaming OC

[quadrax]

Hello

I am not sure what's happening, but from the first test (even light or high, doesn't matter) do one thing. Screen goes black, then go again to back display. It's strange more than it sounds. I am really don't know what or where could be a problem. I have strong PC, cables before are good (tried on Integrated GPU AMD and there was everything ok).

My card is factory new and it does this from first try in everything.

It's not problematic or so, but it's really annoying. Maybe i will try crossflash and will see if the "problem" persist.

My gaming rig is :

CPU : AMD Ryzen 9 9950X
Cooler : AIO Liquid Freezer III 360
MB : ASUS ROG STRIX B650E-F GAMING WIFI
SSD : 3x SSD (500gb, 2TB, 4TB , everything is M.2 NVMe)
PSU : Be Quiet! Pure Power 12M 1200W
GPU: Gigabyte GeForce RTX 4080 Super Gaming OC
RAM : 2x32 GB Corsair Vengeance 6400 MHz (6000MHz, because of weak IMC on CPU)

Is there someone who meet with this problem? Or and if, how do you resolve it ?

Check the cable connections between your computer and the monitor. A loose or damaged cable might intermittently lose the signal, causing the screen to go black temporarily or there is interference from third-party programs.

What BIOS version are you on at this moment of time? If you have a BIOS update pending, flash tot eh latest version, then clear the CMOS.

RAM : 2x32 GB Corsair Vengeance 6400 MHz (6000MHz, because of weak IMC on CPU)
I don't think it's the IMC's fault, perhaps if you were on a better binned ram kit, you'd be able to get to that speeds. I built a friend a PC with a DDR5-6600MHz Dominator Titanium First Edition ram kit, hasn't broken a sweat yet on a B650i Edge WiFi board paired with a Ryzen 7 7800x3D.

I'd use DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually install the latest GPU driver sourced from Nvidia's support site, in an elevated command, i.e, Right click installer>Run as Administrator.

Cables are ok. I just check them out. Tried also turn off MSI AB. Tried crossflash (with colorful BIOS), same, no change at all.

BIOS on motherboard i have latest beta 3056

RAM - If i raise RAM speed i am getting errors in CPU / RAM tests no matter what i do, but still its unstable.

GPU - Will try again download latest Nvidia drivers, but before i am gonna uninstall them through DDU. Then we will see.
