i already short the problem, thank you.

sorry for the late reply, my stb is fiberhome hg680-P with s905x 2gb ram. i disabled the zram swap to test if the ram usage could exceed 1024mb. i've attach the armbianmonitor. after search other site, i want to stripe down the cma memory size via dtb. as i can see the cmafree are around 900mb. but i dont know how to resize it. in hope the ram usage could exceed 1gb.as for now i dont know how to do it. armbianmonitor.txt

i have stb with s905x , ram 2gb with essencore brand, 8gb emmc essencore. after install armbian with mason_gxl_p212.dtb it boot fine. the problem is system only can use 1gb at max and the system start to unresponsive. while the free -m still see available 800mb free. how to make the system can use all available ram?
