I increased my 7700k to 4.8GHz with 1.250v and tested Cinebench several times—everything worked fine! Games ran smoothly, but after installing Adobe Pro Premiere I wanted to learn editing. As soon as I clicked render the computer crashed and became unstable, even basic BIOS functions failed. I restored everything to default or switched back to BIOS. Could anyone help explain what might have gone wrong? (CPU Cooler: Cryorig h7) Even at maximum temperatures were around 70°C.

Well 1.25 at 4.8Ghz is quite challenging, consider 1.28 if the temperature permits. The Premiere setup likely relies on AVX instructions that demand significant processing power. You might also want to experiment with LLC or adjust the AVX offset setting, which could require a higher value.

Workloads don't always affect the CPU equally, and stability can vary between tools like Prime 95, gaming, Premiere, Cinebench, Blender, etc. It might be better to increase the voltage or lower the overclocking.

I concur with Eximo. 4.8GHz @ 1.250v is... as he mentioned, quite ambitious.
Adobe Photoshop.
Adobe After Effects.
Adobe Premiere.
Photoshop / After Effects / Premiere Plug In's.
All utilize AVX.

Eximo:
The specs at 1.25 for 4.8Ghz are quite demanding, maybe go with 1.28 if the temperature permits. Premiere likely uses AVX instructions that require more power. You might also want to test LLC or adjust the AVX offset setting.
Oh well, it seems to work now! I didn’t know about 'AVX' before.
You asked why youtubers suggest running Cinebench and if it passes, issues shouldn’t arise? They increase voltage during editing, right? Sorry for the confusion.

I also rely on Cinebench for quick checks. Usually, when stability is confirmed, my system remains steady during use. I previously used AIDA64 to verify stability across different scenarios. Nowadays, I run 'important' tasks on a laptop and keep my tower reserved for gaming.
AVX instruction sets provide dedicated hardware that speeds up specific operations beyond the general processing core's capabilities. Under typical conditions these components remain inactive. When activated, the rest of the CPU continues to function normally. The extra demand reduces the effective voltage the CPU receives (this is more complex but a basic explanation should be adequate). Setting it higher in advance helps maintain a higher voltage during intense usage.
Load Line Calibration defines a power curve that adjusts with load. Greater demand means increased voltage applied to the CPU. Each motherboard manufacturer handles this slightly differently, but for me, raising it by one notch above the default or off setting has consistently resolved minor stability concerns.
