14700kf Temperature and Voltage Issue

[Handy1]

Since last year I have a 14700KF on a Gigabyte B760 Gaming X AX mainboard. Since the beginning I started to see high temperature peaks. By starting application it sometimes hits the 100 degrees on some cores and shows thermal throtteling. The voltage of the cores is about 1.3x/1.4x V on idle. But on heavy duty it wents down to 1.0x V (Cinebench R23) and then the tempature is about 67 degrees. The highest value of voltage i could see on some cores is about 1.529 V. 

I already installed the newest Bios with the Intel Default Profile and the newest microcode 0x129. But the behavior is still the same.

Even on limiting the power on PL1 = PL2 = 125W it shows this high peaks. My cooler is a Dark Rock Pro 4 from bequiet. And with a PL of 253W I can see very quick all the p-cores going up to 100 degrees.If I reduce the core multipliers to e.g. 50x p-core, 38x e-core then this peaks are gone and the voltage only goes up to 1.3x V with a temperature of about 84 degrees.

After all this stability issue on the 13th/14th gen CPUs I am wondering if the voltage and temperature with the high peaks to 100 degrees and 1.529 V is resulting quicker degration of the CPU or if this is a normal behavior and nothing to worry about.

Has anyone an answer on this behavior and can help me.

See the attached files after 1 hour gaming of Helldivers 2. You can see the temperature and voltage spikes. 

Is this normal? Or a reason to be concerned about the voltages and temperatures?

Hello Handy1,

Thank you for posting at Intel Community Forum.

To answer your question, the microcode update will primarily improve operating conditions for K/KF/KS processors, with less impact on non-K Series processors.

Analysis is ongoing to address other scenarios that can result in this Vmin shift on Intel Core 13th and 14th Gen desktop processors. Intel will share a progress update on this analysis by end of August.

I hope this addresses your concerns.

Thank you and stay safe.

Hello Handy1,

I wanted to check if you had the chance to review the information that I posted. Please let me know at your earliest convenience so that we can determine the best course of action to resolve this matter.

The issue still exists. With the Intel Default settings and new Microcode 0x129 I still see the temperature and voltage peaks. Here also thermal throttling appears from time to time. Only if I reduce the multiplier to 50x p-core and 38x e-core the voltage stays at maximum of 1.3x volt, the temperature goes up to 86 degrees and no thermal throttling. 

What is a safe setting? I mean the voltage and temperature peaks make me concern a bit. But with reducing the multiplier I lose performance. What do you suggest? The new official statement is not helping at all.

Hi Handy1,

Thank you for sharing this information.

I will be coordinating this with our team for more information and suggestions that will allow you to use the processor safely.

Hi Handy1,

Good day!

I received more information from our team and I'd like you to know that the maximum operating temperature for the Intel® Core™ i7 processor 14700KF is 100°C, as reported by the temperature sensors. This is the highest temperature allowed, though instantaneous temperatures may briefly exceed this value. Please note that the maximum observable temperature can be configured by the system vendor and may vary based on design.

If the temperature spikes to 100°C during gaming or other tasks but does not remain there, this is considered normal. Additionally, the maximum operating voltage for the processor is 1.72 volts. For detailed information, please refer to the 13th Generation Intel® Core™ and Intel® Core™ 14th Generation Processors Datasheet, Volume 1 of 2, specifically page 186 under section 13.2.1.1 VCCCORE DC Specifications.

For further details, you may find the following articles helpful:

• Thermal Design Power (TDP) in Intel® Processors
• What Is the Maximum Operating Temperature of My Intel® Processor?
• Why does Intel® Core™ Processors Enable the Throttling While Gaming?

We also recommend running the Intel® Processor Diagnostic Tool (IPDT) and Intel® Extreme Tuning Utility (XTU) tests to check the processor's health. Please be aware that it is normal for the temperature to throttle during these tests.

Thank you for choosing Intel, and have a good one!

Thank you very much for the detailed answer. Then I am less worried.

But one more question what I found in the datasheet of the 13th/14th gen processors:

What is exactly the difference between ICCmax und ICCmax.App? And where do I set up ICCmax.App? In the BIOS I can only find a ICCmax to set up.

[JedG_Intel]

Hello Handy1,

I'm glad to hear that you are less worried about the running conditions of your processor.

For the difference between ICCmax and ICCmax.APP, you may want to check in with your board manufacturer for a detailed information since they are the one who implements these settings. Also, these terms are generic and I also recommend that you ask for assistance with them to find these specific settings as they might have a different term for it.

I hope that you find this information helpful. Have a good one!

Thank you Jed. I was not getting an answer from gigabyte so far on it. But anyway. I think you can close this case.

[JedG_Intel]

Hello Handy1,

Thank you for understanding our position. Since the support will be continued by your board manufacturer, I will be closing this inquiry. If you need further assistance, please submit a new question, as this thread will no longer be monitored.

Have a good one!
