Processor: i9-14900K
Motherboard: MSI MAG Z790 Tomahawk WiFi (bios 7D91vHB
2024-04-24 newest as of 2024-05-09)
Cooling: Arctic Liquid Freezer III 420 Black
Disks: 2x Kingston KC3000 1TB M.2 PCIe in RAID mirror
RAM: G.Skill Ripjaws S5, DDR5, 64 GB, 6000MHz, CL30 (F5-6000J3040G32GX2-RS5K) (2x32gb=64gb)
Power supply: Seasonic FOCUS GX-1000 ATX 3.0 1000W

I have a problem with sudden loads, even short-term ones, and especially with more complex ones, e.g. code analysis by phpstorm or another PHP JS code analysis tool, etc.... and changing the resolution of IRP graphics. rendering. tests, e.g. Cinebench R23, temp max all 100 degrees even with a power limit of 253W

In general, the problem seems to be that 3 cores have a temperature very quickly around 100 degrees Celsius, while the others have 10-15 degrees Celsius more or less.

With cooling set to MAX speed or 30%, it does not matter.

I have tried various optimization methods related to undervolting, etc. using Intel(R) Extreme Tuning Utility, but the result is poor, and when I lower the power limit to below 150W, it is below or around 90 degrees, but the efficiency is -35% +- approximately

It seems that my processor is damaged or missing
Just starting Windows 11 already causes jumps to 100 degrees and thermal throttling

Optimization using Intel(R) Extreme Tuning Utility using AI gives a benchmark performance of 12800-13500, but the temperature during the test is 100 degrees Celsius, the result is still below average (usually)

Cooling installation, paste, etc. checked 3 times, disassembly/assembly/test etc. no difference

What should I do to return the processor to the seller? or maybe it's something else?

hello there Frankii

Given the nature of the tasks you mentioned, such as code analysis and rendering tests, it's not uncommon for the CPU to experience high temperatures, especially with demanding workloads like Cinebench R23. However, reaching a maximum temperature of 100 degrees Celsius, even with a power limit of 253W, suggests that there may be an underlying issue.

Regarding the MAX speed or 30%, this disparity persists regardless of the cooling settings, whether set to maximum speed or 30%.

before contemplating returning the processor, let's delve into a few additional troubleshooting steps to identify the underlying cause of the issue

  1. Tried to update your BIOS. Sometimes, BIOS updates can include improvements or optimizations that address compatibility or performance issues with newer processors. To update, contact your motherboard manufacturer,

  2. Verify that all components in your system, including RAM, storage drives, and peripherals, are compatible with your processor and motherboard. Incompatibilities or conflicts could potentially contribute to performance or thermal issues.

  3. Confirm that your power supply unit (PSU) is capable of supplying adequate power to your system components, including the CPU. Insufficient power delivery can lead to instability or throttling under load.

  4. Use monitoring software to track temperature readings and identify any patterns or anomalies. Consider adjusting fan curves or investing in additional cooling solutions, such as enhanced CPU coolers or case fans, to improve thermal management.

If, after following these steps, you continue to experience significant performance or thermal problems, and you believe the processor may be defective, you can explore options for returning or exchanging it with the seller. Be sure to review the seller's return policy and warranty coverage to understand your options and ensure a smooth resolution process.
