When I use Orange Pi Prime to do some heavy compliation tasks, the gcc compiler sometimes mysteriously segfaults, and memtester catches memory error. As the lima-memtester cannot support H5 (Mali-450 GPU equipped), there's no really reliable way to detect DRAM stability except try and error.
Lower the DDR frequency to 624MHz seems to solved the issue.
Set the default frequency to 624MHz in the defconfig, as 672MHz is observed to be unstable at least on my board.
