hello, have you tried reprogramming the bios?

pin 2 and pin 5 are communication pins the correct way to check them and with the oscilloscope
peep

The card does not work normally, the memory chips or GPU were dumped, it was the same with faulty memory on channel A (First problem at: 0x0-0x1f0 - U2200 + U2300)

I could not check memory with tserver. It does not give any results.

I replaced the bios and i am getting different results.
No, I am looking into the PERST signal, I just can not find what it is connected to on the board. It is pin 11 i know in PCIE but where does it go?

Does anyone know?
I tried to trace it but no luck :(

The PERST signal goes to the U100 (6) then to the GPU, shims feeding the GPU, power circuits, and fans.
