Gigabyteg RTX3080 into system crash repair

The GIGABYTE RTX3080 crashed into the system, and after dealing with the over-hole (wire plug + tin paste), the card tested fine.

Machine model: Gigabyte RTX3080

Fault phenomenon: can light up normally, once digging system crashes

Maintenance process: get the machine, first hit the value of the core of the resistance value is normal, the power supply voltage is normal, the test function can be lit normally. Into the system to play the driver, a run test on the crash. Measure the waveform of the power supply, found that the memory four-phase power supply has a phase of normal cold card, after the heat is obviously not normal, check found that the DRMOS SW output pin and inductor is not even. After removing the inductor, I found that the copper layer on the front and inside of the inductor hole was broken.
