![]() At the moment the graphic card is fully assembled and it's used in my PC, according to the GPU bios the fan is not even supposed to start up until the hottest component on the card reaches 65 degrees Celsius. My memory could be wrong though, please take this with a grain of salt. Pin 6 is connected to refin pin on up9512p. I haven't taken notes of the voltages on the Q32 pins but if my memory is correct pin 1 is connected to GND, there was 2.7v on pins 2, 3 and 4 and there was some voltage i can't remember on pin 5. ![]() Pin 6 connects to the reference voltage input pin 1 of up9512p through a 100 ohm resistor (there is another 2.7k resistor from up9512p pin 1 to GND). ![]() I'm attaching a photo taken with my phone (i hope it's clear enough) of the defective component in the memory VRM circuit. I found another identical component in the fan controller circuit and swapped them around, this fixed the memory VRM but of course now the fan doesn't work. The problem ended up being a SOT component marked Q32 on the PCB, which is generating the reference voltage for the memory VRM controller up9512p (it was outputting exactly 0.3v, which the up9512p faithfully replicated at the memory VRM output). ![]() Hello, I (almost) repaired an Nvidia RTX2080 card where the memory VRM was outputting only 0.3v instead of the expected 1.35v. ![]()
