A while back I went to a fun overclocking event held by AMD, where there was a lot of vapor, some exploding burritos, and some overclocking that got tantalizingly close to 7GHz. It was just an arbitrary number, and they broke a bunch of other records, but they couldn’t quite hit that last target. But a few months and I can only guess how much liquid helium later, they nailed it.
