Performance of QuestionProcessor Shows Fluctuations in Threshold Levels
Performance of QuestionProcessor Shows Fluctuations in Threshold Levels
someone told me if you get your OC stable at specific voltage you have to increase it by [ +0.05v ]
If you're stable at any overlock/voltage, why bother adding more to it? I'd advise on leaving things alone if all your stress testing and gaming sessions don't reveal any instabilities.
Playing with voltages can be risky and often doesn't yield good results.
If you need to ask this question, it's best not to.
A chip designed for higher performance would likely have been used in a more costly processor.
For gaming purposes, using turbo boost is usually more effective than trying to speed up individual cores.
First, ensure your motherboard is up to date to prevent harming your processor.
It's possible to adjust the settings to a range between 5.1 and 5.4 on certain cores if this advice holds true.
The process involves manually adjusting the voltage and gradually boosting the multiplier until instability appears. Once instability occurs, you can add 50mV and perform a stress test. If stability returns, increase the multiplier again. Repeat the cycle.
Eventually, increasing voltage will lead to higher power loss during testing or cause the CPU to overheat, potentially damaging it. Electro migration becomes more likely as voltage rises.
Applying more voltage—whether through hardware changes or BIOS settings—shortens the lifespan of your CPU. I generally cap my i7-4770K systems at 1.250V Vcore for 4.1GHz, with 1.30V as a safe upper limit for Haswell. Going to 1.40V or higher is risky without extra cooling like a de-lid, Peltier, or LN2 system.
The key is achieving full stability at the highest safe voltage without exceeding it unnecessarily. Excess voltage brings more heat and reduces longevity.
As @geofelt noted, the 12700 likely comes from chips that didn’t meet the 12900 benchmark. This means only the faster-running chips were labeled 12900, while slower ones stayed at 12700. You’re unlikely to reach the extreme speeds of a 12900 chip with a 12700, due to binning practices.
Overclocking is a personal decision. I don’t use PBO on my 3800X or 7950X, but I carefully overclock older models when needed. Stay cautious!
it's different from the first one regarding power plans. the second concerns a problem with overclocking, so please delete all my posts. i should go elsewhere to ask my question.
