One more for the club, but mine is a R5 3600 batch May 2020. finished the build two weeks ago, ran all sorts of stress testing (CB20 several times, Prime95 for 20 minutes, Realbench for 30 minutes, CPU-Z for 30 minutes) and never got an error. Today, playing Assassin's Creed Syndicate for 15 minutes, it suddenly rebooted. I restarted the game, played for one hour without issues. I am running CPU at stock and the only OC is the XMP enabled for my RAM. By reading all of the comments in here, I am not sure what to think.
It's not the first time I play the game, I played for around 13 hours, 8 hours of Destiny 2, and no issues.
The highest temperature I got was 81 degrees during Prime95. While gaming, it goes up to 70 degrees. GPU never passed 79 degrees.
