As is known, since the end of April, AMD has been distributing microcode updates among motherboard manufacturers, which helps to eliminate some of the shortcomings. For example, the AGESA 1004a update reduced the system boot time and improved compatibility with some memory modules, and the AGESA 1006 expanded the overclocking capabilities of DDR4 memory.
However, colleagues from the PC Games Hardware website after analyzing the complaints of the owners of the AMD Ryzen 7 and Ryzen 5 processors on the forums of the motherboard manufacturers' sites came to the conclusion that the current versions of the microcode need correction of one more annoying error. Under certain conditions, which most often imply manual modification of the processor voltage by the user, Ryzen 7 processors can "freeze" at 1.55 GHz, and Ryzen 5 processors at 2.2 GHz. The system functions normally, but it is not possible to raise the frequency above these values, and this is determined not only by the indications of diagnostic utilities, but also by measuring the speed.
Some motherboard manufacturers have already recognized the problem, and are working on its solution through the BIOS update. As a preventive measure, the authors of the publication on the German site recommend not to change the voltage on the processor manually, or to disable energy-saving technologies. True, power consumption will increase, but the processor's performance will not suffer.
