You most likely won't see your chip hit 45x while benchmarking.
You will only see it boost to 45x briefly in Windows desktop while idling or with light usage bumps while monitoring with something like HWiNFO64 to record the core spikes.
With PBO your 3800X might boost to ~44x(+) with CB R20 (single core) but CB R20 (all core) will run much lower speeds.
For example... My 3900X (4.6GHz max boost) will run CB R20 (single core) with just some cores/threads hitting ~44.50x/44.75x/45.00x but while running CB R20 (all core) my chip runs the bench lower with all cores/threads loaded ~40.50x/40.75x/41.00x.
