The HWinfo utility has the opportunity to convict some motherboard manufacturers that they deliberately endow them with a feature that can reduce the life of AMD Ryzen processors.
The fact is that these processors rely on data on current power consumption coming from the board and used to dynamically control the clock frequency. Underestimating the readings of the power sensor, it is possible to make the processor believe that it has the ability to overclock. According to the developers of HWinfo, such a “trick” can lead to overheating and reduce the service life of the processor. Unlike overclocking, in which the user takes additional measures, the fraud on the part of the board occurs in a regular environment and without notifying the user.
Here’s how developers describe the essence of the problem:
“Some motherboard manufacturers intentionally provide an incorrect (too small) reference value in AGESA. Since AMD Ryzen AM4 processors rely on the data received from the motherboard when evaluating their power consumption, an incorrect reference value affects their power consumption. For example, if the manufacturer of the board installs it half of the real one, the processor will consider that its consumption is half the actual value.
In this case, the processor allows itself to double the specified limit of energy consumption. He will be able to increase the clock frequency, without abutting the power limit; however, it will heat up more, which potentially negatively affects its service life – just like overclocking. ”
