This is pretty bizarre. You'd think that at -180 degrees hitting boost speeds would be a snap considering they are supposed to do that at normal temps.
So I set out to see if adding more cooling would help get my store-bought Ryzen 7 3700X to hit or exceed its advertised top-speed of 4.4 GHz. What I found out is that, even when I used liquid nitrogen to freeze my processor down to -180 degrees Celsius, it was still stuck at 4.35 GHz, 50 MHz below its boost. However, as we'll see below, you can hit boost clocks by manual overclocking.
