Hi guys! What is going on? It is my first time here. I hope you can help me:

I used Clock-Tuner Program getting the following DIAGNOSTIC and RESULTS:


Code:
Diagnostic results
Max temperature: 56.4°
Energy efficient: 3.66
AMD Ryzen 5 3600 6-Core Processor
Your CPU is SILVER SAMPLE
Recomended values for Overclocking:
Reference frequency: 4250 MHz
Reference voltage: 1250 mV
Recomended values for Undervolt:
Reference frequency: 4125 MHz
Reference voltage: 1175 mV
Code:
Calculation of penalties for the final profile:
18:33:29: CCX1 (127): 4250 MHz, 1250 mV  OC=
18:33:29: CCX2 (116): 4275 MHz, 1250 mV  OC=
Cinebench 20 started
Cinebench 20 finished with result: 3771
Voltage: 1.25 V  PPT: 64.1 W  Temperature: 64.2°


profile 1: OC


Profile 2: Undervolt


Here the parameters:


Now I want to add these parameters to my BIOS and I did it like this:

1- I've set CPU Frequency and VID Change in MANUAL and I put the CTR parameters: FREQUENCY = 4125Mhz & VID= 1,175



2- CPU LLCalibration = from "AUTO" to LEVEL 2 (I have changed it for Clock Tuner) - I have doubts if I have to change something in CPU vCORE voltage, I think I don't.


3- This is where I have more doubts: It is like I have to put the same parameters did I did in the first step (first picture). So I am not sure if I have to modify them or not...I put the same parameters that Clock Tuner gave me for Undelvolt:


I start Computer and Ryzen works in the correct way that I expected: It is undelvolted: Voltage in constant of 1.175 and temperature decreased from stock. It is now between 38º and 44º with more stability.

The question is: Is my BIOS OK? I guess, I have the doubt if The picture 1 and 3 are the same thing and I have to put CPU Frequency and VID Change in AUTO or, on the reverse, I have not changing anything in the Picture 3.

Thanks a lot!

You're currently on version 2.90 for your BIOS, while the latest version is 3.60. I'd advise on updating the BIOS gradually to the latest and then try with the undervolts. I think you're good as is, those voltages and temps seem good.

Hi @Lutfij and thank u for your quick reply!

Just for curisoity...How do you know I am curretnly on v 2.9 of bios? You're right. It is just for curisitoy. xD

When my Computer is working well I am not fan of update my BIOS (you know, there is a little a risk that things can get worse). How must I update the BIOS? Directly from 2.90 to 3.30 or must I install also 3.20 like this : 2.90 > 3.20 > 3.30??

Thanks in advance!

EDIT: LOL! Meanwhile I was writting this post ASROCK has lauched new bios:

Focused on new ryzen 5000. Is is recommended updating to the latest version now 3.60?
thanks!

Bcoz Bios version 3.60 has a different UI.
