I successfully overclocked my new Ebay PC.
Specs: Gigabyte GA-Z87X-UD3H motherboard, Intel i5-4670K CPU, 16 GB Crucial Ballistix RAM, be quiet! System Power B8 550W.
It ran stable even with 4.3 GHz and 1.20 Volt on a Temperature around 70 Degrees even running 10 Minutes stress-ng. Stock GHz was 3.4 GHz.
My very first kernel panic. It toke some work bringing up the desktop, 1.265 Volt done the trick. Temperature was rising to 79 Degrees and it was just not worth it. so i went back to 4.3 GHz.
Of all my time using Linux, I've never seen a pink kernel panic screen - did this happen at boot?
Edit:Found my answer. it was introduced in Linux 6.10 via drm_panic (Direct Rendering Manager subsystem) - allows the GPU driver to show this even if a display server is running. Magenta's a common default for the GPU's primary framebuffer plane.
There might be a BIOS/UEFI setting in your motherboard to configure that - under where the "fans" settings are located - like a "Shut down / safety temperature". That's just a protective measure to prevent CPU damage. The underlying cause (heat dissipation, fans, dust) should ideally be checked.
It seems unlikely heat alone would ever trigger a kernel panic. It makes sense to happen on overclocked systems when they run too fast.
