CPU core voltage with Intel recommended settings goes up to 1,5V at times and with ASUS recommended settings goes up to 1,48V at times. Have been reading in some other online forums that keep saying 1,4 is too high. To be noted, this doesn't constantly stay there. Estimated average voltage during idle is around 1,3V.
An average idle voltage around 1.3V is typical and generally not a cause for alarm. Concern arises when voltage remains elevated during prolonged periods of heavy workload.
The Operating Voltage for the 13th Generation Intel® Core™ Processors will be up to a maximum of 1.72V, in this case, it is ok if the voltages are going around 1.2V to 1.5V.
Usually when you increase CPU speed and notice that your system is unstable, you need more volts. However do not go above 1.4V. Above that and it can be dangerous. Stay between 1.35-1.41 if possible for high overclocks.
Generally, a safe range is between 0.8V and 1.4V, but this can vary depending on your processor model and generation. Additionally, it's best to not change the voltage mode too often as it can stress your processor and motherboard.
Nowadays most PC power supplies have active PFC meaning they work dinamically within a range of voltages, that will usually be between 100–240v, but could be 90–250 or 110–230 or something else. really depends on the specific PSU you have.
It's only really above 1.35–1.375V at full load where you might see significant degradation over long-term use (several weeks or months), and you'd have to go above 1.4V to get degradation over just a few days.
Just make sure the boost clocks aren't kicking the voltage up higher, to something like 1.4v. 1.3v is safe. Anyone I've known that had a long term overclock, they did it with less than 1.35v and their processors never had any signs of degradation.
1.35v is what's generally considered "safe" for Intel, but as Jackrabbit says, at 1.4v you're probably just risking 100-200Mhz in a handful of years when you have a new computer anyways.
We recommend being conservative when increasing DRAM voltage. Increasing voltage too much can damage your system. By default, DDR4 runs at 1.2v, while many memory module kits are rated to run at around 1.35v with XMP. Raise your voltage slowly until your system is stable; we recommend not going above 1.4v to be safe.
Lower voltage is never a bad thing, as long as it's stable in all your programs, and especially if it's stable in AIDA64 stress test using Stress Cache only, then you're golden.
Regardless of the differing Tjmax temperature, seeing temperatures this high is still concerning. But, it would take the processor spending much more significant amounts of time at this temperature before it will have any affect on the lifetime of the processor.
At 50 volts (V) or less, the voltage is generally considered safe, as the current is too low to cause significant harm. Here are some of the lethal levels of voltage that you should be aware of: Low Voltage: Low voltage is typically defined as anything up to 500 volts.
The core-voltage requirement ranges from 0.9 to 1.3 V and is usually defined by specific processor performance criteria. The latest core-supply voltage tolerance require- ments are typically ±3%. The presence of large current transients makes the task of delivering reliable processor power even more challenging.
The Higher the Voltage the more heat is generated which is bad for the CPU. The biggest concern for CPU's is heat as this will cause the lifespan of the CPU do decrease fast. The closest to 0° C you can achieve, the better the CPU performance and increase the lifespan of the CPU.
That should never, ever(!), be over 1.35v (the CPU degrades very quickly!). If for whatever reason you see that "CPU SA Voltage" at over 1.35v, imediately change the "CPU SA Voltage Mode" from Auto to Manual, and manually insert a lower voltage for it.
You should not, under any circumstances increase the voltage beyond 1.5V. It's dangerous and simply not necessary. The extra heat at 1.6V, 1.8V and 2.0V will be immense and you'll seriously damage the components.
Amd.com says it's safe up to 1.45V, so unless you have overheating issues, leave it at default. Those engineers know what they're doing and why they set a voltage they set.
One immediate consequence of supplying a higher voltage than required is the potential physical damage to electronic components. Components are designed to handle specific voltage levels.
1) Most utilities have a + or - 5% voltage tolerance on the delivery. 260 Volts is too high and suggests a utility issue with their transformer. I recommend to contact the local electrical utility have them confirm their delivery voltage to the building.
