Aerohive ap330 / 350 cpu overclock

Hi, have this ap with service release, cpu now is clocked to 533MHz but techdata show 800MHz https://openwrt.org/toh/hwdata/aerohive/aerohive_hiveap-330 - so how to speed this cpu?

Do you see the same CPU clock (533MHz) when you use OpenWrt?

 cat /proc/cpuinfo

Did you eventually manage to do this? I upgraded my AP's with Wifi 6 cards and am now running into a CPU bottleneck @ 800mbits. Would like to crank the CPU to 800mhz but have no clue how to patch U-Boot to do so.
