Question RTX 4070 Restarting TDR freeze ?

[Fastfishy2]

I thought I'd solved this yesterday. Managed to run a few rounds of 3Dmark Port Royal stress test with HWINFO64 running in the background to try and reproduce this weird freezing behaviour I've been getting, but there were no issues. Left it to do another one today and came back from a shower to find it had frozen again. No BSOD, second display / taskbar were erratically usable, and signing back out/in of my windows profile without a reboot removed the freeze.

EDIT: RTX 4070 Asus Dual, latest drivers

Checked Event Viewer and found 3 Error messages labelled "nvlddmkm" with event ID 0. They all reference "\Device\Video3" and "Restarting TDR occurred on GPUID:a00"

This is after I purged the video drivers with DDU, updated bios and cleared CMOS on the mobo, updated my chipset drivers for the motherboard, and did some OS repair stuff via command prompt administrator. So, I'm at a bit of a loss as to what more I can do. Is there some kind of solution on my end or is this something where I just take the graphics card back to the shop. I haven't had this happen during actual gaming and it seems to now exclusively happen during 3Dmark port royal stress test - Speed Way runs fine, and I can't even get it to happen on 100% of the Port Royal runs I do. It just seems to pick and choose at random which runs it will freeze.

What is your computer build? Also are you using any kind of oc utility or running anything else in the background during the tests?

RTX 4070 Asus Dual, 5800X3D, 32gb DDR4 3200 dual channel, strix b550-a motherboard. No OC running, only background process being HWINFO64 polling at about 200ms.

I have reinstalled windows onto my NVME drive instead of my 860 Evo since I posted this, and done clean installs of all my drivers along with it, so I'll just have to see if the issue presents itself again. So far today, two port royal stress tests and one Speed Way stress test have turned up stellar results. I'm going to keep testing for now.
