Ryzen 8700G 780M Black Screen Problem

Hi i just bought Ryzen 8700G also fresh all other components. But i have problem about my APU or CPU i think. Im getting black screen constantly. Even when creating this topic, got about 10 times. There is my pc specs:

  • MSI B650 Gaming Plus Wifi
  • AMD Ryzen 7 8700G [AMD Radeon 780M Graphics]
  • Patriot Memory 7800 C38 2x16GB
  • 750W PSU Bronze 
  • Windows 11 Pro 64bit (22631)
  • AMD Software 24.6.1 [20.06.2024 Release]


Im keep checking all system temp and Volt values with HWMonitor and AMD Ryzen Master. Leaving here my current-min-max values for an example. Black screen happened between these min-max values:

Lastly, i was using HDMI to connect my monitor then switched to Display Port for get 144Hz to 165Hz but nothing changed. Same with both cable connection. My screen resolution is 2K (2560x1440-165Hz) and HDR on. Tried on 1920x1080 and result was same still getting black screen. Is there any way to detect actual problem about CPU or Motherboard and solution for this?  Thank you!

There are no DDR5-7800 memory modules certified on your motherboard QVL list - the highest speed memory listed as compatible is DDR5-7200.

Yes i know that and my RAM speed is: 5200Mhz [Task Manager] Is that  why i am getting black screen?

Update:
I connected 1HDMI & 1 DisplayPort monitors to my case and when this black screen happining on my First screen, second screen was OK. Also tried that first monitor on another case and there was no any problem. So hard to detect really problem for me..

Which type HDMI or DP is exhibiting the problem? Have you tried another cable, or a different port?

What are the resolution and refresh rate of the monitors? Which has the problem? Have you tried resetting defaults? Disable Freesync?

Tried with these settings:
-HDMI & DP
-1920x1080 - 2K [Monitor supports 2K-165Hz]
-144Hz[HDMI] & 165HZ [DP] & 60Hz with both.
-All settings was default.

Freesync was active and i just disabled it. I'll update post after test it for a while.

With disabled freesync still getting black screens..
Also reinstalled Windows 11 to be sure about software bugs somehow, but result was same.

I'll focus and check monitor for that issue and will update.. I hope its the problem here somehow..

320V, do you get black screens with one monitor? Did you get your video and chip set drivers ONLY from AMD? John.

Did you solve the problem yet?

I just built a PC for an office with this chip and it has been happening. Dual screens, one HDMI and one DP.
