Your Raptor Lake CPU crashing in the heat? Here's how to undervolt it to stay cool & stable:

I’ve seen a lot of people lately struggling with random crashes, especially on 13th and 14th-gen Intel CPUs like the i7-13700K and 14700K often during hot weather or heavy loads. Since I’ve been through this myself, I wanted to share a quick guide on undervolting your CPU to help reduce temps and improve stability. Hope it helps someone out there stay cool (and crash-free).

Especially applies to i7-i9-1400K / i7-i9 1400K

BIOS METHOD (advanced users):
Reboot → Enter BIOS (Del/F2)

Find: CPU Core Voltage settings

Set: Offset Mode → Negative

Start with: -0.050V to -0.100V

Save & reboot

Intel XTU METHOD (easier):
Download: Intel Extreme Tuning Utility

Open → Advanced Tuning → Core Voltage Offset

Try: -0.050V

Apply & stress test

Pro Tips:
Don’t use “Override Mode” — kills turbo

Keep BIOS updated

If it crashes: reset BIOS or uninstall XTU in Safe Mode

Works best with decent cooling

Raptor Lake chips run HOT, esp. during heatwaves

Stay Cool Amigos and See you late space cowboy!
