Siema, swojego czasu nabyłem gtx'a z myślą o naprawie. Karta miała zwarcie na linii 12v, po wymianie dwóch DrMOS'ów (dwa środkowe, zdjęcie) zwarcie zniknęło i karta się uruchamia.
Niestety nie daję żadnego obrazu. Sprawdzam ją z procesorem 7900X i płytką X299.
Z inną sprawną kartą nadal tylko ta sprawna jest wykrywana. Brak informacji w menadżerze zadań o naprawianej karcie.
Napięcia są, vcore 0.9v, mem 1.5v. LDO EM5103 jest zasilane i z tego co sprawdzałem sprawne. Wszystkie pomiary itp. wypisałem na zdjęciu poniżej.
Programowałem już bios'a niestety nic to nie zmieniło.
Jeśli wykonam jakieś nowe pomiary będę je umieszczał na zdjęciu.
Proszę i z góry dziękuję za pomoc :mrgreen:

Hello!
Are the voltage measurements on pins 1, 7, 8 of this chip correct?

Measure the voltages to ground on points A, B, C, D:

Yea, they are correct. A: 12v B/C/D: 3.3v but weird thing happens. I put the card in to x8 slot and it works just normal.
