I have a non working 2080 TI that I receive to try on repairing. It doesn't display anything and the fan goes to full speed. I have tried it as a secondary,, there is nothing on device manager on this card. I tried nvflash to see if it even detects the card to re-flash the BIOS in case it is corrupted BIOS. It doesn't appear to detect it either.
Could a corrupted or damage vbios flash chip keep the could from even being detected?
This to me appears to be either failed BIOS or GPU. I didn't find any shorts on the PCIE lanes.
I have tested all voltage rails, everything appears to be present (PEX, 1.8, VCORE, VRAM, 12V and 5V)
I took some resistance reading:
1.8 Volt Rail: 36.2 Ohms (Way too low from what I research)
PEX: 10 Ohms
3.3 Volts on the PCIE slot: 18KOhms
12 Volts at the PCIE slot: 6.1KOhms
5 Volt Rail: 70KOhms and 12 Volt Rails: 17.5KOhms, 6KOhms and 5.1 KOhms
Memory: 18 Ohms (SAMSUNG VRAM)
