I upgraded the hp bios on this machine to 2.23. It seems to have unlocked everything, so maybe the old bios i had was messing things up, or im an idiot. I unlocked 1024 cores, went into PBE and set the rx560 power limit to 50w, changed the memory to 1750mhz along with uber timings, and saved. Now im getting about 5900 graphics score (firestrike) compared to 4200 graphics score, which is perfect 42% linear scaling comparing 50w to 35w. I also have the upgraded (from i5 8500t) i7 8700 TPL (turbo power limits) limited to 50w as well using throttlestop and task scheduler. Quite a peppy little 1 liter machine i must say. Temps are still well within range usually hovering around 80c and peaking about 85c for both GPU and CPU. This has to be near the limit though as hwinfo64 shows 135w system power peaks and i dont know how much further would be safe to push the 150w power brick. Try at your own risk.
