Overclocking, volts, tests, we’re PC Tuning, right? Everyone is a master overclocker as long as the CPU is alive. And when he roars after a tuner hit, it’s too late to worry.
Igor (Igor’s Lab) discovered a very dangerous bug in the MSI Center application that allows the Ryzen 7 5800X3D to be overclocked far beyond its limits. Although this seems like a good thing, the opposite is true. This CPU basically has lower clocks because the 3D cache is very sensitive and cannot handle what the regular Ryzen 7 5800X can handle. Therefore, the voltage is limited to 1.35V, this is the official maximum specified by AMD, but of course the processor uses less. Igor took advantage of a bug in the application and applied 1.3V to the processor, and then a little more, and the PC turned off. Needless to say it wouldn’t boot and the CPU was dead. But the bug allows up to 1.55V to be burned into the CPU, which is equivalent to the so-called “instakill”, i.e. immediate detonation.
Further investigation revealed that the same error also occurs in ASRock, Asus and Gigabyte applications. And we will add to the topic that der8auer tried a similar experiment with the Ryzen 7950X3D processor. To be sure, he cooled with liquid nitrogen, but as soon as 1.55V went into the processor, it was gone immediately. So if you’re working with your AMD processor with 3D cache, be damn careful about the volts. For now, there is no fix or update on the horizon to fix this.
