Possibly spread spectrum.
On topic, I'd go with PBO. My multicore results are within margin of error and my single core will boost up to 4425 on my 3700x with PBO enabled. Single core load temps are in the upper 50's while multicore can typically hit high 60's mid 70's (360mm CLC).
Don't waste time trying to manually oc the core, focus on getting the highest stable IF/fclock.
