Vega 56 not boosting to state 7?

I have a Vega 56 flashed with V64 bios and am currently working on dialing in the clock and voltage settings.

In Wattman, I have left the core frequency at the default "dynamic" but have undervolted slightly.
My current setting are
state 6: 1537 MHz @ 1050 mV
state 7: 1632 MHz @ 1100 mV
HBM: 1050 MHz (I have set the voltage to 1050 mV, but from reading forums it seems this may actually be a minimum voltage for the core??)

Anyway, while keeping Wattman and GPU-Z open on my second monitor while playing Destiny 2, I see that my core clock is never exceeding 1560 MHz, and that the VDCC field in GPUZ never exceeds 1.0500 V even though the GPU load is 100%. Does this mean my card is "getting stuck" at state 6 and never going up to state 7 and that is why I'm not seeing the core clock that it is set to run at? My temps are topping out at about 69C, so I don't think thermal throttling should be an issue.
