Hello guys.
I have an Asus b660m and my 13600k. Bios updated.
Default settings in BIOS sets TURBO MODE ENABLED, but this causes CPU voltage to stay fixed in 1.4v all the time and 5.1GHZ.
Question is:
Is this normal? cause 1.4v its too high, temps are getting much higher. 
If i disable TURBO BOOST, i get 0.968v and normal temps, with 3.5GHZ(default clock). But this way am i losing performance? 
Is there a way to get TURBO BOOST with 5.1GHZ with lower VCORE ? My old 10400f reaches boost clock of 4.2Ghz with a vcore lower than 1.00vCaptura de tela 2023-03-28 215247.jpg

polas, Thank you for posting in the Intel® Communities Support.


We will be more than glad to assist you with this matter. 


In reference to your inquiries, it is important to note, as you mentioned, that we always recommend to use the Intel® processor under stock configuration with the default BIOS settings. Altering clock frequency or voltage may void any product warranties and reduce stability, security, performance, and life of the processor and other components.


The T-junction of the Intel® Core™ i5-13600K processor is 100°C, any temperature result lower or equal to that value is considered normal and expected for this unit:


In the following link, you will find the "Overheating Symptoms and Troubleshooting for Intel® Boxed Processors", for you to be able to confirm if your processor is actually showing any of those signs:


Third-Party tools, such as CPU-Z, might not be that accurate in the reports and results shown on the application. Based on that, in order to rule out a possible hardware issue with your Intel® processor, please install and run the Intel® Procesor Diagnostic Tool, it does an overall test on the unit and if it passes the test it means it is working properly:


Every processor works differently, especially if they are different generations, they cannot be compared, The Intel® Turbo Boost is a feature that works automatically depending on the load of work at a particular moment. So, if those values are correct, then yes, it is expected to see them, and for that reason, there is no need to disable the Turbo Boost in the BIOS: 


What is not that normal is if the clock speed and voltage stay fixed, they normally should fluctuate. Some boards have some default settings that overclock the processor automatically. Taking that into consideration, we recommend to get in contact directly with ASUS Support to:

-Confirm if the BIOS is actually working at default settings

-Verify if there might be a setting that is overclocking the processor automatically 

-Make sure that the latest BIOS version is currently installed on the board or gather the instructions on how to update it:


Any questions, please let me know.

Thanks for reply Albert!
I always try to let CPU at Stock settings, but this time i cant, because as i said, 1.4v is not normal on IDLE. So i'm trying to mess in BIOS for an option that fix this issue. 
- Bios is updated to last version and default/optimal settings already;
- The only "overclock" possible is the Turbo Boost, because my B660 doesnt allow overclock;

I think its probably some setting in Asus bios.
Thanks again.

polas, You are very welcome, thank you very much for your response.

Yes, that is correct, all the details you described indicate that this scenario is related to a BIOS setting, and ASUS should be able to provide additional assistance on this topic since they handle everything in regard to the support of their BIOS.

Any other inquiries, do not hesitate to contact us again.
