Hello,
Is there a dtb for the gt king pro? The gpu speed is rated for 843Mhz but the generic beelink gt king locks the gpu frequency at 800Mhz.
Could we perhaps manually set the gpu frequency in /flash/config.ini?
see:
I think you talk about RAM clock speed and not CPU clock speed. The RAM speed can not be changed as it’s hardcoded by the bootloader. There is no real “GPU”.
You are able to overclock the CPU by config.ini, yes.
EDIT:
I am sorry, maybe I was wrong. There is a gpu clock in the dts:
But it include already 850 with a clock of 846000000Hz.
But no idea where and who does choose it.

Hey, I decompiled the dtb file and found below. When I remove the first tbl entry when the device loads it’s max_freq shows 3 instead of 4, and still defaulting cur_freq to 800Mhz.
cat /sys/class/mpgpu/cur_freq // shows 800
cat /sys/class/mpgpu/max_freq // shows 4 normally, and 3 when first table entry removed.
So I guess what I need to know is what entry in the dtb file do I change so it loads the last table entry, 0x7E ?
