The default RAM clock frequency for all @PINE64 devices in pmOS v21.03 is at 528 MHz. We ran it slightly faster before at 552 MHz, but with this change we ensure it runs on all #pinephone s.
Thanks to @BobbyTheBuilder, power users can now increase the clock speed up to 624 MHz with "update-u-boot -r" in edge. Bobby made this video, showing all three side-by-side: https://odysee.com/@Newbyte:7/pp_sd:b
