How to undervolt i5 12400f on Gigabyte B760 DS3H AX

[gulma2]

Hello, I saw some guides showing to go to Vcore section and set to adaptive mode and then legacy, and then offset option, but I don't have an offset option, the only time I get an offset option is if I do fixed mode, but that worries me - does it then mean its not adaptive at all and will crash if it hits exactly the limit or is just some different wording that doesn't do anything...

Also some other guides showed changing the Turbo power limits instead, which I am now not sure which one is correct and what to choose.

I am using stock intel fan so the CPU gets hot and fan very noisy.

Also how do I check if i'm blocked from undervolting or not? I have F9 BIOS - do I need to update it or something?

Most B760 boards do not allow the sort of options for undervolting that you mention. For a Gigabyte B760 DS3H AX updating to the latest F10d BIOS is recommended because it runs the Intel default settings as standard. This may help with the CPU heat and/or fan noise.

If they don't to the degree you want then an option to consider would be to replacing the stock cooler with a 120mm fan tower cooler of some form such as the Cooler Master Hyper series.

I  have a Gigabyte B760M  DS3H AX  DDR5 MB with i5 -13500, it updated the latest bios F18D, but the new microcode 0x129 is not shown in the bios, and intel default settings are missing, I asked for a gigabyte, but they told me   K, KF, KS series are affected, so you don't need to worry.

Your processor  12400f is not affected 

You can adjust the fan speed to silent, and change the stock cooler to  AIO  360 Liquid cooling, I have an AIO 240 LIQUID cooler.  

Thanking you

Thank you - and any of these settings will not help?

No change is kept as an auto. 

Dont upload photos to third party websites, you  should upload on this site

See processor voltage, also check the temperature in your  processor

Thanking you

1.326 V! Gigabyte's default LL_AC setting is nuts.

1.328 I kept as default, 

In bios, I set the following

Power loading = Enabled
CPU thermal monitor = Enabled

I was referring to the vcore of your i5-13500. But that's also something the OP could have a look at. This is probably the only way to lower the voltage of non-K CPU's on B-series boards rn.

Thanks for your information. I recently updated bios microcode 0x129, but the non-K series does not update the microcode. 

Even though I don't have any stability issues, the current v core is 1.328. The current microcode for 13500 is 0x35.

I'm talking about the unnecessarily high default AC_LL setting used by Gigabyte. Microcode has nothing to do with it.
