Hi Everyone
Ive got an RTX 3070 Gigabyte vision oc that i picked up from a miner who said one day it just stopped working. The card isnt detected and has no display, the core gets very warm within 30 seconds and i have all voltages on the inductors
12v, 5V, 1.8V, Vcore 0.7v mem 1.35v and pex 0.9v
My resistances are 5v 0.9k ohm, 1.8v 30 ohm, Pex 6.6 ohm and the rest are normal
any ideas besides dead core?
With the pex reset B11 pin am i supposed to get 3.3v supplied from the motherboard? at the U501 logic gate i am not getting any voltage from the input pins 1 and 2. i have 1.8 vcc and ground but no supply from the motherboard. Should this be a 3.3v signal to this gate and therefore a 3.3v signal leaving the gate?
Here is a link to the u501 datasheet

I will also include a screen shot of the diagram for the U501. the board doesnt have the U503 or R514, but does have the r535 but i dont get 3.3 v on either side of it and i have direct continuity between pin A11 and pins 1,2 on the logic gate
This is my first 3000 series card so still learning. I do have a gigabyte 3090 in my pc but im not massively keen on pulling it apart to compare it unless i have to.
Thanks, Kurt
