it seems to have helped, but i also put performance enhancer mode from AUTO to level 3 OC in bios, of my Asus X570 E gaming motherboard
Ah, that is simple. Because Bus speed can hover around 99.98-100.03 mHz, depending on mobo and settings and actual CPU speed is determined from this by multiplier. So it can be 99.98*45=4499.1 mHz. And different tools reports stuff more or less precise.
For HWINFO 99.98 = 100.00 basically, because normal step for BCLK is 0.1 mHz even for top tier motherboards iirc.
Another possibility as there is some another factor that limits max boost clock for this specific core. Like for my cores it can be voltage requested (they likely get to border of their V/F curve even despite offset). But it shouldn't be an issue for 4500 mHz, though. More than that, it only affects effective clock, not nominal clock.
Disabling spread spectrum in the bios might help you hit the round number of 4.55Ghz on 1-2 CPU cores.

Improvements are real
Hi, i know this is a old thread. May i know what bios setting did you configure to get the boost clock pass 4643Mhz ? I have the same proc & mobo with you. My maximum boost is 4550Mhz for a few cores. Can you share the bios settings? Thanks.
Hi, enthusiast I'am faceing with next gen Zen5 now, but yes I have some Bios capture of this BCLK 102.25 setup

Hi guys, as you can see, then YES 5800X3D can do 4.55ghz all cores in games only BCLK 102.25 C-states & CCPC Preffered Enables in BIOS CO-22
