Hi ,
my Raspberry Pi 4B has a passive aluminium cooler "enclosure". I use it as audio kodi server (no video stream).
With no overclock, sometimes during reproduction big .flac files the player stop working for somes seconds, so I little overclocked adding to /boot/config.txt:

and it's better but no perfect. The temperature is ok:


Now, using xbian-config command and choosing -> Settings -> System -> Overclocking a window appear with advice:

but ones closed the advice I see no presets to choose, there are only two options to manually insert.
My question is how to load the tested overclocking settings combinations? And which you use as good compromise?
Thank you

This can't be a Raspberry Pi 4B you're talking about

So which is the best overclock setting compromise speed/temp you're tested for raspberry pi 4?

The Raspberry Pi 4 is now only on standby for me.
When I was still developing/testing with it, I always had
in use

In my opinion overclocking doesn't make sense anymore

Xbian has tested different overclocking settings and created a most preferable combination of settings

but ones closed the advice I see no presets to choose, there are only two options to manually insert.

Xbian’s overclocking presets should appear in `/etc/xbian/overclock.conf`. If they don’t, update your system:

```bash
sudo apt update && sudo apt upgrade -y
sudo reboot
```

For better FLAC playback, manually set in `/boot/config.txt`:
```ini
arm_freq=1750
core_freq=600
gpu_freq=600
over_voltage=2
sdram_freq=500
```
Then reboot:
```bash
sudo reboot
```

Your cooling is good, so this should be stable. Let me know if issues persist!

Xbian used to provide predefined overclocking settings, but on the Pi 4, this feature might not work correctly due to differences in firmware. That’s why you only see manual entry options in xbian-config.
