The Libre Computer roc-3328-cc has dd4 ram.
By porting these two vendor patches

libre-computer-project/libretech-u-boot@cdb523f
libre-computer-project/libretech-u-boot@7c0723f

the clock frequency is increased to 800Mhz (actually the clock frequency is 330Mhz).
this makes the system much more responsive and solves problems related to the playback of 4k streams reported by users on the forum (https://forum.libreelec.tv/thread/27677-rk3328-4k-hevc-stutter-frame-drop/).

I will try as soon as possible to understand if they can be sent upstream
