The stock speed for the little cores is 1.4GHz and on the big cores it is 1.8GHz, however the OP1 speeds default to 1.5GHz and 2.0GHz instead.

DTB is in <code>/boot/dtbs/rockchip/rk3328-rock64.dtb</code>. CPU clock rates are inside <code>opp_table0</code> as hexadecimal numbers in the <code>opp-hz</code> field.
Check the achieved clock speed with <code>sudo cat /sys/kernel/debug/clk/clk_summary | grep armclk</code>. Does not seem to overclock at stock voltages at all, defaults to 408 MHz if it fails to set a clock rate. Stock voltage is 1.30V, just shy of the 1.35V maximum outlined in [https://www.rockchip.fr/RK3328%20datasheet%20V1.1.pdf the datasheet]. Overvolting to 1.325V just left the device in an unbootable state for CounterPillow, would not recommend.
GPU needs investigating, but is seemingly tied to the bus speed.
