Why is the OCing head room for the RX 6000 series so low?
You have plenty of Thermal Headroom and the Power Filtering is pretty good, AMD should allow a much higher limit like AHOC suggests.
AHOC suggest that the upper Frequency limit be set to 2x the base Frequency instead of 2.8-3.0 GHz which is what it is set at the moment by AMD's BIO's depending on which model.
