Subject: Issue with Intel Core i9-14900KF Processor

[VirusB]

Hello,

I am experiencing an issue with my Intel Core i9-14900KF processor. When the system is idle, it automatically closes all applications, such as the browser, Discord, and low-demand games. However, if I launch a demanding game and minimize it, I can use YouTube and other applications without them being forcibly closed.

I have already tried adjusting the processor settings based on MSI's recommendations, but unfortunately, these adjustments did not resolve the issue.

My system configuration:

• Processor: Intel Core i9-14900KF
• Motherboard: MSI MAG Z790 MAX Wi-Fi (BIOS 7E25vA8)
• RAM: G.Skill 7200MHz
• GPU: ASUS ROG Strix RTX 3090

Hi VirusB,

Thank you for posting in the Community

Given your system configuration and the steps, you've already taken, I recommend checking for a BIOS update for your MSI MAG Z790 MAX Wi-Fi motherboard. Sometimes, a BIOS update can address compatibility issues and improve system stability. To ensure the update is performed correctly and to avoid any errors, I suggest reaching out to MSI for further assistance. Here's the link for reference: MAG Z790 TOMAHAWK MAX WIFI

Once you've updated the BIOS, please let me know if the issue still persists. I'm here to assist you further and explore additional solutions if needed.

Thank you for your patience and cooperation.

Hello Dean,

Thank you for your response.

I have already updated my BIOS to the latest version. I also tried undervolting the processor, which improved stability during low-performance tasks. However, for high-performance workloads, I experienced performance drops of 20-30%.

Additionally, I am unable to update Windows to version 11—during installation or updating, the system simply reboots.

Do you have any other recommendations to resolve these issues?

Best regards,

VirusB

Hello! In the updated BIOS version "7E25vA8," a gaming mode was added. I enabled it and manually set the CPU VR voltage to 1.28V instead of Auto. As a result, my PC is now fully operational again. The frequency is stable at 4.8 GHz, which is great.

If you have any recommendations on how to adjust the BIOS settings to achieve a frequency of 5.2-5.5 GHz while maintaining stability, I would appreciate your advice. Let me know if it's convenient for you to share your insights.

Hi VirusB,

I hear your concerns about adjusting the BIOS settings to achieve a stable frequency of 5.2-5.5 GHz. I'll be looking into this internally to see if there are any solutions or tips that could help you reach your performance goals. Please know that I'm dedicated to keeping you updated and will get back to you as soon as I have more information.

Thank you for your patience and cooperation.

Hi VirusB,

Regarding your inquiry about achieving a frequency of 5.2-5.5 GHz, it's important to note that the CPU's ability to reach higher speeds can vary significantly based on workload and system conditions. While some CPUs may achieve these frequencies under certain circumstances, it is not guaranteed for all workloads or configurations.

Just to add, As a general best practice Intel recommends users adhere to Intel Default Settings on their desktop processors.  Intel is not changing the tuning capabilities of existing K sku processors.  Users who desire to overclock or utilize higher power delivery settings than recommended can still do so at their own risk as overclocking may void warranty or affect system health (learn more at Overclock Your CPU with Unlocked Intel® Processors - Intel). 
 

I recommend proceeding with caution and prioritizing system stability over raw frequency gains. If you have any further questions or need assistance, please feel free to reach out.

Best regards,

Hello,

On the Intel website (Intel Core i9-14900KF Specifications), it is stated that the processor reaches a frequency of 6.0 GHz. While this is achievable with the stock BIOS, I have encountered extreme instability at low loads.

I understand that overclocking voids the warranty, but the 6.0 GHz frequency is within Turbo Boost specifications. For the past year, I have been searching for a solution to maintain stability while achieving a frequency above 5.0 GHz. Recently, I discovered that enabling "Game Mode" in the latest BIOS and manually setting the CPU VR Voltage to 1.320V, along with a maximum frequency of 4.8 GHz, improved stability.

Could you provide an official settings guide for this processor to ensure stability while maintaining a frequency above 5.0 GHz? Any recommendations regarding voltage, power limits, or BIOS configurations would be greatly appreciated.

Best regards,

VirusB

Hi VirusB,

To help improve system stability, I recommend checking the following link: Improving Stability of 13th/14th Gen Intel Core Processors.

If you are experiencing instability even under low workloads, this may indicate a defective processor. Our standard troubleshooting steps for instability include updating the BIOS and setting it to "Intel Default settings." If the problem persists after these steps, there is a possibility that the processor is faulty, and we can offer a replacement.

Additionally, if you are unable to locate certain settings in the motherboard configuration, you can contact MSI for further assistance with additional settings. You can reach MSI support through this link: MSI Support.
