This GPU is very popular and can be used for barbecue, there is a possibility of burning your leg. You want to lower the gpu frequency. Find the following method after google. First, su is root (root permission is required for the following operations) 1 sudo su and then 1 echo mid>/sys/class/drm/card0/device/power_profile to use low, run at a lower frequency. The result is flushed and changed to mid. View result 1: mount none/sys/kernel/debug/-t debugfs2cat/sys/kernel/debug/dri/0/radeon_pm_info displays the following results (GPU half-speed running) 1 default engine clock: 400000 kHz2current engine clock: 209250 kHz3default memory clock: 330000 kHz4current memory clock: 135000 kHz5PCIE lanes: 1 after several minutes, the GPU region temperature decreases significantly. The air outlet temperature is also reduced a lot. This operation is automatically performed after the instance is started. Add the following code to 1vi/etc/rc. local: 1 echo mid>/sys/class/drm/card0/device/power_profile.
