AMD's Ryzen 3000 Boost Fix Works, But Often Hits Wrong Cores

According to this report, AMD's Ryzen boost fix works but probably still needs some work.

We've discovered quite a few encouraging traits with AMD's new boost-fixing BIOS and the Ryzen 9 3900X processor that extend beyond 'just' the expected heightened frequencies, but we also found a weakness in the chips' inability to hit the rated maximum boost speeds on all cores (the chips come with a mix of faster and slower cores). That often results in our Ryzen 9 3900X boosting on inactive cores, thus providing no performance improvement in some workloads.
