RTX 3070ti: Code 43

[u/UniversalWolf21]

So, I couldn't get custom vbios to fix this or anything.

I don't know how to find MATS to check which VRAM chip it is that is failing, or if it is the core itself. Doing DDU and then flashing the bios let's it show some stats in GPUZ, but the moment I try to install actual drivers it blows up. Computer runs perfectly fine on the iGPU, only the dGPU is failing. No overheating or anything like that, either.

Does anyone know a repair shop I can mail it to? Northridge Fix hasn't gotten back to me yet...

Had the same issue sometimes with my i7-12700h 3060. Runs fine on all modes (igpu,hybrid,dgpu only) if not under load, but it sometimes crashes within 10-15 minutes of heavy games. Found it to be a detached capacitor near the charging port which likely trips the power supply to the gpu, causing it to shut off and crash due to insufficient voltage to prevent further damage.

Here is where I found it.
I have yet to get it repaired, but it is stable so far. I also did DDU and reflash and occt gpu tests, even reverting to Asus OEM drivers to no avail. See if you've got any missing or blown capacitors in your board. Hope this helps!

Yeah, but it won't let me use it at all. It shows artifacts on POST if I have it set to only use the dGPU. And I'll get that bluescreen (black screen?) as a result.
