MSI GTX1070 brak obrazu

Witam,
Mam na blacie leciwą już kartę od MSI, mianowiceie GTX 1070 Gaming X o oznaczeniu MS-V330
Karta ma wszystkie napięcia prawidłowe, rdzeń nagrzewa się do max 36st ale nie startują pamięci.
Karta nie jest wykrywana w systemie.
Jest ktoś w stanie pomóc w temacie ?
Dodam jeszcze że BIOS karty też już wgrałem świeży.

Mierzone z radiatorem czy bez? Jakie napięcia do masy masz na cewkach: L1, L19, L20, L22, LB11, PL1 i PL9 podczas "pracy" karty?

Pomiary bez radiatora.
L1 - 5,063v
L19- 12,32v
L20 - 12,31v
L22 - 1,844v
LB11 - 1,019v
PL1 - 0,883v
PL9 - 1,387v

Przelutuj GPU do rozpływu i sprawdź, czy karta wystartuje.

Reflow wykonany, różnica jest taka że karta wymusza czarny ekran ( daje sygnał) ale nadal nie jest widoczna w systemie. Temperatury bez zmian

What is the revision of the board?

V330 ver: 6.0

- Measure the voltage to ground on pin 16 of chip I1.
- Measure the voltages to ground on pins 1, 4, 5 of chip U5.

I1 pin 16 - 3,34V
U5 ( It is not present in this version )
pin 1,2 - 0V
pin 4 - 0.08V

Set your multimeter to the diode test mode and measure the voltage drop to ground on pad 1 on the place of chip U5 with the positive (red) probe connected to the ground.

0,42V

Also measure the voltage drops to ground on points A, B with the negative (black) probe connected to the ground.

A small correction, I connected the card directly to the board and not to the riser (as before) and in the PCIe slot the card receives a voltage of 3.3V on U5 on pins 1, 2 and 4. It took a while due to lack of time.

- Is the graphics card still not detected in "Device manager"?
- How about the measurements suggested in post #12?

The graphics card still not detect
The voltage on point A and B is this same - 0.5V

Use an oscilloscope to check if any data pulses appear on pin 1 of the VBIOS chip U3 immediately after turning on the card.

On pin 1 of U3 we have the ROM_CS_R signal and when the computer is turned on there is a constant 1.7V.
There are no impulses here or any waveform.
Does this mean the GPU is dead?

Possible, or there may be bad solder joints/contacts on the GPU chip.
Remove the GPU chip from the board and inspect the board for any pulled pads under it. If the board is fine, reball the GPU.
