You can run your i3 12100f at 1.4v without issues, as long as the temperatures remain stable.
It only raises power usage, but as long as it's adequately cooled, it won't damage the component.
Was es einen Grund dafür gegeben, den CPU bei hoher Spannung zu betreiben?
My CPU power cap is set at 1.35v, which usually provides enough performance even after overclocking. I also use adaptive voltage, but a fixed setting works just as well—just a bit of tweaking can lower the voltage while maintaining solid frequency. It seems you're likely using BCLK for overclocking, as it's controlled through the multiplier.
F represents the point where the igpu failed or Intel intentionally shut it down. It matches the standard CPU exactly, without the igpu. S/T models are low power, aimed at HTPC, laptops, etc. K is unlocked multiplier, KS is factory overclocked or tweaked. There’s no strict cap on BCLK beyond physical constraints. LN2 overclockers often increase BCLK to gain performance, which can also reduce the multiplier for stability.
Asus OC, OC Genie, and similar boards started using BCLK OC at 103.3, then moved to 105.7 and reached around 107.4 for maximum overclock. If your board can handle that BCLK, you could increase the multiplier by 3 to 400MHz, which would likely bring the overall speed up to about 600MHz.
Regarding voltage limits, they depend on the specific CPU. Sandy Bridge and Ivy Bridge support up to 1.4V, Haswell supports 1.3V, and Ryzen stock single-core reaches 1.5V. There’s no fixed rule—just general guidelines based on the chip type, usage, and intended purpose. For safe operation, a Ryzen core at 1.35V is preferable; 1.35 is safer, 1.325 is ideal for daily tasks.
Wow, it looks like I completely overlooked this—BLCC overclocking is back with the 12th gen. It’s impressive, though, especially on top-end systems.
EDIT: It seems these upgrades are mainly for high-end boards; I was hoping to finally refresh my old rigs, but Intel caught me off guard.
I believe consistently applying this voltage could harm the RAM. However, if you're in a cooler environment, there should be no problems with using such high voltage.
