It will boost one core at a time and fairly briefly. Obviously, it won't boost to that clock speed under heavy work load but it doesn't have to be idle so run a lightly threaded work load; a quick-scan in Defender works pretty well. Since it boosts pretty quickly a faster than normal polling period also helps, I use a polling period of about 500 mSec's in HWInfo. Then look at the multiplier graph for each of the cores and watch which ones boost to 4400.
This assumes you've installed the AMD chipset drivers and are running the Ryzen Balanced power plan. Also helps a lot to set Cool n Quiet, Advanced C-States, Processor CPPC and CPPC Preferred Cores all to ENABLED in BIOS if you haven't.
In truth, the actual performance gain from hitting 4400 is hard to measure and probably not much if you could. The real performance comes from maintaining moderatly elevated clock speeds...4200-4300MHz...under heavier processing loads. That usually means better (than stock) cooling to keep it from dropping back as it gets hot.
