Can you read the marking on red circle IC? On photo it is unreadable.
Also which IC pins are 0OHm-to-ground?
The only IC that I saw on GPUs in TSOT23-8
without a choke/coil near is up1801 - "programmable high-precision reference voltage".
Вложение:
UP1801-reference-voltage.zip
Its top marking is N21. It was near PWM controller, but the card was another: high-power AMD 290/390.
There is a lot of TSOT23-8 voltage converters, but thaey are always near choke/coil
- Top marking 08= Richtek RT7296F
- Top marking ADP Monolithic Power MP1475
- Top marking AMX Monolithic Power MP1475S
Is there a small choke/coil on the other side of the board near that ic?
