Hi all, so this problem is driving me crazy. A couple of days ago, the GPU started underclocking itself to 1200mhz. I have not made any visible changes that may have caused this. I have only been downloading Windows 10 updates.

I was using the latest stable MSI Afterburner version, and even after I uninstalled it/stopped using it, the problem persisted. I have no idea what to do to solve this problem, so any help is greatly appreciated.

Notes: My GPU version is XC Gaming (RTX 2070). Motherboard is Z390-F Gaming, with latest BIOS Update installed. Nvidia driver is up to date. Fans seem to be fine as well. I haven't noticed any abnormal behavior or temps. Nvidia power setting is set to "Optimal Power", and changing it to "Prefer Maximum Performance" did not make any difference (problem persisted).
 
Edit: It is worth adding that the underclocking keeps going on and off, but there is seemingly no justification for it, because 1: The game I'm playing can use MORE resources than given when the GPU underclocks itself. 2: It is not a problem with the fan/temps. Something else must be messing things up.

Doing what is suggested in this thread should keep it from underclocking.

Hey, thanks, but that's not what I want, nor the problem. I don't want the card to stay highly clocked all the time. I simply want it not to underclock while at load (which is what happens currently). It used to stay highly clocked while at load automatically, but couple of days ago, that behavior ceased from being consistent, and I don't know why.

What has been installed or updated to the PC since it started to underclock? 
 
Might have to head back a previous system image before all of this started and see if that works once you run out of troubleshooting options.

Windows 10 updates are the only thing that changed recently. Today I went ahead and upgraded to the latest Windows 10 version, and changed the power setting in Nvidia control panel, so I'm hoping I fixed it.
