So you can disable SMT in AMD processors to lower the temperature

[Inkriql]

The SMT (Simultaneous Multi-Threading) technology of AMD processors allows each of the physical cores to be able to execute two tasks simultaneously, or as we commonly put it, doubles the number of process threads with respect to the cores. However, deactivating SMT may also have some benefits, such as a reduction in processor operating temperatures or, in some cases, may even improve performance in some specific tasks or games. We show you how you can deactivate the SMT of your AMD processor easily and without complications.

The SMT technology in AMD processors takes better advantage of the processor's pipeline, always keeping it with instructions to execute. This means that both virtual cores of each physical core are always in operation, which means an increase in the consumption of the processor, its workload and, therefore, its operating temperature.

If for some reason you need to disable this technology and make the processor work only with the physical cores, without virtual processes, you can do it easily and quickly both from the motherboard BIOS and using the AMD Ryzen Master software. We show you how you can do it in both cases below.
Disable SMT in the motherboard BIOS

Each motherboard manufacturer locates the parameter to deactivate SMT in a different way, but in all of them it will appear in the "Advanced" and "CPU Configuration" section. Within this, we will have a parameter called “Simultaneous Multi-Threading”, “Multithreading” or simply “SMT”, and we will only have to change its value to “Disabled” to deactivate it.

On ASUS boards, this parameter is found in Advanced -> CPU Configuration, while on MSI boards it is found in the Overclocking -> CPU Features section. On Gigabyte and AORUS boards, we will find it in the M.I.T. -> Advanced CPU Core Settings, and on motherboards of the ASRock brand this is in the Advanced tab -> CPU Configuration, as in ASUS.

Each manufacturer has a different name and they are in different sections, but it should not be complicated to find it in any of the cases because in all it is in the menus related to the processor.
Disable SMT with AMD Ryzen Master

With Ryzen Master it's even easier, and it doesn't matter which motherboard manufacturer we have. We will simply have to open Ryzen Master (if you do not have it, you can download it from the AMD website), open the profile that we have active (“Current”) and in the section called “Additional Control” we will find the parameter called “Simultaneous Multithreading” , which we can deactivate simply by clicking on it.
