Some points to remember:
Any operation that exceeds the specified current threshold will accelerate the degradation, the pseudoscience occurs when trying to determine by how much as these things aren't easily quantifiable, hence nobody has proper data.
Intel whitepaper specifications for VID or otherwise are concluded after risk assessment and based on stock frequencies only. One we increase the frequency the spec sheets are no longer valid.
Whilst not speaking directly to Z590/690/790, on older platforms where users were more inclined to use power viruses such as Prime - internal testing consistently found that subjecting the CPU to high current workloads rapidly accelerated electromigration. Fundamentally, you only need to look at how Intel implemented AVX2 mechanisms to combat power consumption under certain workloads.
Perfect! Agree with you!
We create our own fear.
Intel's datasheet explicitly states voltage, power, and temperature limits.
Everyone gets scared when they see idle voltage close to 1.5V, even if the temperature is low and power consumption is minimal.
On the other hand, as soon as we start tweaking the CPU on the motherboard, we ignore Intel's recommended LLC, remove power limit protections, and completely change core scaling and voltage to a fixed mode.
We do all of this and subject the CPU to an effort far above any acceptable level for hours and several days.
But all of this doesn't seem to create any kind of fear or embarrassment because the monster we've created is called voltage, and that's what must be fought.
There seems to be no problem testing the CPU for hours above 95°C and 300W as long as the voltage is within a value we simply pull out of a hat.
If we check the vf tables for processors, we'll see that there are CPUs with voltage values above 1.500V for turbo frequencies.
Do Intel engineers not know that voltage is the real monster that destroys the CPU?
Do we need to teach them that processors should be sold with all-core frequencies locked and with a fixed voltage?
I guess that's why we don't see any Intel engineers participating in forums... Lol.
Once again, I say... There's nothing wrong with configuring the CPU by synchronizing all cores and fixing the voltage...
But when things go wrong, let's be fair in assigning blame. It's not worth deceiving ourselves.
