Question Is it okay to run a cpu at 1.4v?

[championapple123]

I have a i3 12100f and I ran it at 1.4v and had stable temperatures. Is there any harm in doing this?

No. It just increases power consumption, but as long as it's being cooled properly it isn't going to harm the part.

Any reason why you ran the cpu at such a high voltage?

My limit on CPU's is 1.35v and that tends to give me all the power I need even with an overclock. I also go for an adaptive voltage but fixed is fine though with some fine tuning you can drop the voltage and still have a good frequency. I presume you are using the BCLK to overclock as it is locked via the multiplier upwards.

Blck is tied to the dmi / pcie on anything above skylake i dont think that is possible above 103.3mhz, maybe small gains. I also thought the "f" means locked multiplier but i might be wrong.

F is where the igpu failed or Intel purposefully burned it out. It's intrinsically the same as the regular cpu, minus the igpu. S/T are low power models, designed for htpc, laptops etc. K is unlocked multiplier, KS is factory overclocked/tweaked.

Theres technically no limit on BCLK other than physical limits. LN2 overclockers regularly crank up the BCLK for extra gains as it can mean lowering the multiplier for stability.

Asus OC, OC Genie and others were using BCLK OC starting at 103.3, then trying 105.7 and hitting 107.4 ish for ultimate OC. If you had a board capable of withstanding that BCLK. Also would bump the multiplier 3-400MHz. Would net a 3-600MHz OC roughly.

As far as voltage limits go, that's entirely cpu dependant. Sandy/Ivy-Bridge could handle 1.4v, the Haswells 1.3v, Ryzen stock single core goes upto 1.5v. So there's no set rule specific, just common sense limits depending on the cpu, how it's used, what's used etc. You'd not want a Ryzen multi-core at 1.5v, 1.35 is safer, 1.325 max for all core daily use etc.

Oh wow i seem to have completely missed this happening, it seems to like BLCK overclocking is back with the 12th gen : https://www.techpowerup.com/review/intel-core-i3-12100f/22.html

Only on higher end boards but still this is something really cool.

EDIT: seems like its super high end boards only, i was hoping to finally update my over decade old rigs but intel fooled me

I think continuously using this voltage will damage the RAM. But if you are located in a cooler place then there will be no issue using such high voltage.
