Config or disable ddrfreq throttling

Recommended Posts

Hello!

 

Is there any way to config the frequency used by the DRAM driver when throttling takes place, or even better, disable the DRAM throttling at all?

 

First of all, I have to say that that I'm pushing my Orange Pi Zero H3 board to run at very hot temperatures due to my CPU throttling settings so I can play some retro arcade games (I know I may burn it).  But it seems the DRAM driver has its own throttling settings, and it takes place reducing DRAM frequency to 132Mhz. At such DRAM frequency there is flickering at HDMI output.

May 13 18:30:31 inova-casa kernel: [15484.645873] [hotplug]: cpu2 is killed! .
May 13 18:30:31 inova-casa kernel: [15484.647486] [ddrfreq] DDR: 408000KHz->132000KHz start
May 13 18:30:31 inova-casa kernel: [15484.647500] [ddrfreq] current cpu is cpu0
May 13 18:30:31 inova-casa kernel: [15484.648753] [ddrfreq] elapsed: 1087us
May 13 18:30:31 inova-casa kernel: [15484.648773] [ddrfreq] DDR: 408000KHz->132000KHz ok!

Unfortunately,  manually setting the DRAM frequency don't work either. I mean, when I send the command, the frequency don't change.

sudo echo 480000 >/sys/devices/platform/sunxi-ddrfreq/devfreq/sunxi-ddrfreq/cur_freq
