I Fixed My RX 6700 XT Not Detected Issue and You Can Too!

Gigabyte Gaming OC RX 6700 XT not detected by the system? In this repair, I diagnose why this RDNA 2 GPU has all voltages present but still won't be recognized. The culprit — a faulty AND gate on the PEX reset line, likely damaged from a previous repair attempt. All main power rails check out: 12V PCIe, 3.3V, 1.8V, 12V 8-pin and 6-pin have no shorts. Core and memory voltages are present when powered on. But the AND gate driving the PEX reset signal has no output despite having valid inputs — a known failure point on AMD RX 6000 series cards. Watch the full step-by-step: resistance checks, microscope inspection, board cleaning, AND gate replacement from a donor board, and successful bench test with display output. In this video, you will see: Initial resistance checks for shorts on all power rails Power-on test showing core active but no detection Disassembly and microscope inspection of the PCB Identifying a faulty AND gate from previous repair work Systematic voltage measurement across the board AND gate replacement using a donor board component Diode mode and voltage verification on the PEX reset line Bench test confirming the card is now detected Full assembly with new thermal paste and pads Windows driver installation and stress test (Heaven, FurMark) Important note: This repair involved hot air soldering on a multi-layer PCB. Working on GPU boards carries risk — if you're not experienced with micro-soldering, consider professional repair.
