ClockTuner 2.0 for Ryzen (CTR) Guide - How to beat the 5GHz

How to beat that 5GHz

With Zen 3 microarchitecture's appearance on the market, the battle of frequencies gained momentum again; as the new processors automatically approached the psychological mark of 5GHz, it was possible to expect that the processor in CCX mode would get that desired frequency. Some of them believed that it only depended on the processor. Some of them put 4 radiators trying to decrease the temperature in the circuit by 0.1 degrees, and some just tapped their foot and demanded that B450 "top-of-the-line" overclocked flagship processors like Ryzen 9 5900X and Ryzen 9 5950X. In the end, no one was right, because only a certain percentage of users don't buy a motherboard for the money left over after buying all the other accessories, mats, and wrappers.

Staying true to tradition, today's tests will be conducted on the ASUS ROG Crosshair VIII Dark Hero motherboard.
 

This sample is not another spin on marketing fantasy but has several unique features that will help me with overclocking. The ASUS ROG Crosshair VIII Dark Hero has 8 phases with double the number of elements, 7 of which are for the CPU and only 1 for the SOC. The PWM controller is ASP1405I.
 

 
Schematically it looks like this:
  

As you can see, this implementation does not contain doublers, which now like to think of as a full phase implementation, but in fact, all doublers work in in-phase, meaning there is no time shift, which means it is still the same parallel "mode" that exists only to increase power. Are 7 phases (14 virtual) enough for extreme overclocking? Yes, it is, since the more phases, the more stable the power supply.

Below, note the red line, minor undershoots, and overshoots.

As far as cheap motherboards go, it will look something like this:

This is not critical for factory boost in applications with fairly light instructions but is quite critical for any overclocking. During overclocking, as the voltage increases, so does the current. It would be best if you also kept in mind that AVX is a load that requires a huge amount of current at a rather low operating voltage. In any case, the need for high current triggers a chain reaction, when the load heats up the MOSFET, and the higher the temperature of the MOSFET, the less current it can provide.
