Hello everyome, ive found this 3900XT for like 90$ and guy said that he could boot with his a320 motherboard altrough the 1 pin is missing, and as i found out on internet that one missing pin is VSS. I got that processor and after pressing power up button nothing starts not even the fans. The motherboard i tried to run on is ROG Strix B450-F Gaming, and yeah i have updated bios to latest and i was running my 5600X on it. Tried everything in order to get boot but im not sure now it will boot. Any tips?

A VSS pin is ground, and a modern chip has multiple ground pins. Losing one shouldn't be the end of the world - but a damaged pin is still damage, and outright losing a pin without damaging others in the vicinity would be extremely lucky.

I can't see a damaged or missing pin in the image - but that's likely my eyes. Circling it may get you more interest/traction in the thread.
