Questions about undervolting my i5 13600kf after latest microcode update (0x129)

Hello everyone!

Ever since I bought my i5 13600kf last year I noticed it got extra hot (100 ºC) during stress tests/heavy gaming so I undervolted it a little bit. I used this guide to do it.

By the way, I have air cooling - Scythe Fuma 2 Dual Tower - SCFM-2100 Rev.B.

The undervolting was successful - max temperatures got 15-20 Celsius degrees lower (80-85 using the same stress tests) and max VCORE was around 1.25-1.27 - without loss of performance -, so I did not bother with it anymore.

And then the whole thing with the 13th gen and 14th gen CPUs started and I got worried... This week I finally updated my BIOS to the latest Intel microcode (0x129), which seems to have erased my previous underclock settings.

So I went ahead and followed the same steps from the mentioned guide, albeit without choosing the 0x104 microcode this time. Unfortunately the temperatures increased again - not as much as previously, but still something that is kind of bothersome. Stress tests take the temperature to around 92-95 degrees and VCORE peaks at 1.279 V.

My questions are:

Now that we know about the degradation situation, will it still be safe to use microcode 0x104 WITH the undervolting settings?
If I should not use microcode 0x104 (meaning, I should use the latest, "safest" one), with the current results I am getting (VCORE 1.279 and max temps around 92-95), am I safe? Meaning, will my CPU degrade or not?

Sorry if this seems extra obvious, I just thought it would be quicker to ask about my exact scenario here.

Thank you so much!

Hello fraga500,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

When did you purchase your processor?
When did you start having some issues?
After updating the BIOS to the latest, what will happen if you are using the default BIOS settings?

If you have questions, please let us know. Thank you.

Best regards,
