Question How do I prevent excessive CPU overclocking with BIOS settings on ASRock PRO Z790 PRO RS WiFi motherboard ?

[docboy]

Hi all, I just finished my build over the weekend. i7-13700k, 32 GB DDR5 RAM, ASROCK Z790 Pro Wifi MB

From watching a few youtube video channels, it seems that some motherboard manufactures automatically tries to push the CPUs to the max wattage to achieve optimal performance. Bios by default sets the CPU to an "overwattage" setting which then causes excessive heat.

Per Hardware Canucks, ASUS calls it "Multicore Enhancement." To prevent the CPU from pushing it to the max and pushing 100 C, in ASUS one needs change Multicore Enhancement fro 'Auto' to 'Disabled - Enforce All Limits'

On the ASROCK motherboard, where does one go into Bios to ensure the CPU watts do not exceed 13700k's max turbo power of 253W?

ASROCK bios is not clear. Is it "Base Frequency Boost" under "OC Tweaker" ? By default "Base Frequency Boost" is set to Auto. I have the option to choose 250W, is this the setting to prevent the BIOS from allowing the CPU to exceed 253W?

There are many ways to achieve this.

MCE basically allows the system to ignore the per-cores in use limits. So, say 5.6Ghz single core, 5.5Ghz two cores, 5.4 Ghz 4 core, etc would be ignored and all cores would run at 5.6Ghz. Honestly if you are buying a K class chip and you don't use MCE, you might as well have bought the 13700 (which is what I would do these days)

Base frequency boost will let you change the baseclock boost frequency. Normally, the base clock would be when all cores are loaded and the tau power limit duration is reached. Again, typically ignored on a K SKU by default. Essentially this is a time limit for allowing the baseclock and base power limit to be exceeded.

You can just set a straight up power limit if you don't want it to exceed a certain wattage.

Many people also set a negative voltage offset. Reduced voltage should keep temperatures better under control, but also allows for potentially higher performance since this will decrease wattage.

If you want to know more I suggest looking at a detailed overclocking guide. This will familiarize you with the various options and what they do so you can set the behavior the way you want.

Thanks for the response and explanation.

Can you confirm, with Asrock Bios, where does one set a power limit?

I can't off the top of my head, should be fairly easy to find in the manual.

It will certainly be with all the other major CPU settings. Likely next to the Tau and other features.
