I'd like to bump the GPU up to 600 from 500 MHz on my RPi 4 B. I've edited /boot/config.txt to include:
but when I run vcgencmd I get the following results and gstreamer is no longer able to record video to a file:gpu_freq=600
I am running the latest Raspbian Buster image, though I'm having issues upgrading the firmware, which is being dealt with in another post. I am running a custom kernel at this point. I've added drivers & overlays, switched to low-latency preemption, set default CPU governor to ondemand, and upped the kernel from 100 Hz to 1000 Hz.
