Hello
Error 43 gets when your system try to load video driver and it return this error - communication between GPU itself and the system.
There are 2 situation in which you obtain this :
1 - the GPU chips is broken (or some electronic pieces that surrounds it but not the memory chips)
2 - when the drivers are not correct or you have a wrong version of BIOS file written in your card.

Assuming that you did not flashed any BIOS in it recently, we will start the diagnostic from here.
What did you do prior to receive this error?
I mean sometimes you can receive this error because windows updated the video driver by itself and ened up in installing a generic driver.
So basically we need more details in this case.

Os could be borked as well,
 
True also
 
Run sfc /scannow from the cmd prompt. Use Display Driver Uninstaller DDU to remove the driver in safe mode. Then reinstall the driver and pray it works. GPU-z is not good, reminds me of a card with a vBIOS issue. You could check with HWiNFO, see if you can detect the clocks etc. Sometimes it can be GPU-z. Others it can be the MS driver.

SFC is pretty laughable this day and age.

Standard procedure for memory overclock and yes it does fix things.

Yeah and a windows update borks the os yet sfc says nothing wrong

sfc /scannow works everytime for me and I corrupt the crap out of my windows install with memory overclocking. I just run sfc /scannow and a few other things and my system is fine. When I was a windows insider for the beta builds of windows 11. The windows update would fail but windows would still recover and restore the system to before the update. Windows update has nothing to do with sfc /scannow.
