All language subtitles for ASRock B650M PRO RS Review _ AMD Ryzen 9 7950X Undervolting-en

*The motherboard used in the test was provided by a distributor in Korea.

The BIOS setting is Default, and the FAST BOOT option is enabled by default.

On average, it took less than 20 seconds to enter Windows.

In the BIOS Default state, TJMAX appears to be set to 85 degrees.

The ASRock's motherboard provides a preset target temperature and curve optimizer values for the Ryzen CPU.

However, in the case of target temperature setting, the performance deviation will occur depending on the CPU cooler, so I will test with manual PBO setting.

The numerical input of ASRock uses mW and mA units.
(You can enter a number of x1000 in the value you want to enter.)

I finished setting up the PBO of 7950X to fit the air-cooled CPU cooler.

The curve optimizer value must be found directly, as the appropriate value varies depending on the silicon lottery of the CPU.
(The worse the CPU, the more values you can put in.)

In the case of Ryzen 9 series with two CCDs, higher performance can be achieved if per CCD is selected.

In addition, if you choose per Core, you can reach higher performance than per CCD, but it is more difficult to set up.

This time, let's set up per CCD, which I explained earlier.

Of the two CCDs, CCD 2 performs relatively less than CCD 1.

For the first CCD, keep the existing value, and for the second CCD, let's increase the curve optimizer value.

I will also apply offset undervolting.

Use mV units instead of V units, and if you enter a number directly, the input is canceled.

You can enter values using the -, + keys on the keyboard. Units can be adjusted into 5 units.

I will enter -0.05V (-50mV).
