Sure it wasn't too complicated really, I can give you the gist of it from memory.
 
1. Burn Armbian_22.05.0-trunk_Rk3318-box_jammy_current_5.15.35_xfce_desktop to usb drive, plug into usb otg port to boot.
2. Go through basic install routine as usual until you get to armbian desktop
3. You should see your emmc drive as a desktop icon
4. open terminal
5. mount your emmc and important dirs, I don't think I had to mount boot dir ymmv
example mount /dev/mmcblk2p1 /mnt
mount -t proc proc /mnt/proc
mount -t sysfs sys /mnt/sys
mount -o bind /dev /mnt/dev
mount -t devpts pts /mnt/dev/pts
chroot /mnt
6. Use armbian-config to install working kernel (6.6.32) as well as update bootloader.
7. Exit terminal and shut down system, once you no longer get a signal to display unplug usb drive and power cycle to verify bootup and you can freeze with armbian-config once booted up.
 

I overclocked the CPU to 1.4MHZ using the voltage 0x1437c8, governor = conservative.
opp-1200000000 { opp-hz = <0x00 0x47868c00>; opp-microvolt = <0x13d620>; clock-latency-ns = <0x9c40>; status = "okay"; }; opp-1296000000 { opp-hz = <0x00 0x4d3f6400>; opp-microvolt = <0x137478>; clock-latency-ns = <0x9c40>; status = "okay"; }; opp-1392000000 { opp-hz = <0x00 0x52f83c00>; opp-microvolt = <0x1437c8>; clock-latency-ns = <0x9c40>; status = "okay"; }; The system has been working steadily for several hours and the browser is working faster.
Earlier I tried to overclock to 1.4 using the voltage 0x1312d0, but the system received errors almost immediately as soon as I started the browser.
My DDR is still 533MHZ. I want to raise the frequency to 600 - 660MHZ.
As I said earlier, I use a radiator with a fan
 
Just in case, a photo test point for RK3318 v.1.4 to launch a TV box in the maskrom mode

Great thanks for the archive of current version of armbian for rk3318  boxes !!
Now its possible installing one good working version that is not braking more time in the mouths and is getting current updates :-)))

You can check the dpll core clock in linux, it tells you the clock used by the dram controller.
 
cat /sys/kernel/debug/clk/dpll/clk_rate  
It should tell you 666Mhz or 1333Mhz, I don't remember if it accounts for double-data rate or not (but I think not, probably will tell 666Mhz).
 
edit: about the poor youtube performance, it is due to the fact that the cpu is not powerful enough, there is no hardware video decoding yet for videos in the browser and the graphics pipeline is not really well optimized for general purpose desktop environments.

Hello, my H96MAX got a second life. I have damaged emmc memory.
Thanks to your instructions
I can still use it. Boot from sd card.
Great job, thank you.
