Hello,
I need help identyfing what is broken on this GPU - GPU core or VRAM. Let's start with what I did and know so far:
- disassembled, added missing SMD capacitors from same GPU
-(If anybody knows what Q518 is and would share this information I would be very grateful)
- artifacts during Windows booting are blue vertical stripes, I can take a photo if that would help
- artifacts in Windows are yellow-ish horizontal lines
- in BIOS/ text on black screen text gets extremely garbled
- GPU-Z doesn't show GPU or VRAM frequency
- GPU error 43 in Device manager
- after baking on bottom only preheater for ~10 minutes @ 135 degrees - ~80-90 is what TC shows on PCB, probably even less on the core, since it has a giant IHS, artifacts were gone for a few minutes, then screen went blank and artifacts are back
From what I understand 90 degrees on the core is not really enough to bring it back to life, even for the shortest time, but RAMs don't operate on such temperatures, so maybe modules from bank 0/1 are broken?
