Hello,

as my other post got marked as spam for some reasons I don't know, asking in short again:

I have built an AM5 platform (Asus Prime x670e Pro Wifi, 7600x, 2x32 Kingston Fury Beast 5600, 4070 gpu), plenty of stability/stress-tests were okay. full 8 hours memtest86 no errors. Passmark, 3dMark, Heaven, Cinebench, Prime95... no issues. Testing BIOS settings to reduce CPU-Temps (RAM on default, no EXPO etc.): PBO thermal limit set to 75 or 85... OCCT CPU Stability Test immediately gives lots of errors (usually one die I think). Resetting BIOS to PBO Auto. OCCT CPU Test runs without errors.

Question 1: Is there something wrong with the CPU so that I should replace it?

Asking this, because encountered some "instabilities" in games (Jurassic World Evolution, PC Building Simulator 2) that simply close to the desktop out of nothing also after having played maybe an hour or more already.

In BIOS there seems to be another option to reduce temp which is not PBO Enhancement Thermal Limit but Platform Thermal Throttle Limit. Setting this to - let's say - 85 seems not to cause errors during OCCT CPU test.

Question 2: Is there a preferred way to go with temp reduction? PBO Enhancement or Platform Thermal Throttle Limit?

Thx

1. 

If OCCT CPU Stability Test immediately gives lots of errors when you set the PBO thermal limit to 75 or 85, it could indicate a potential issue with the CPU or its cooling solution. However, before concluding that the CPU is faulty, it's essential to consider other factors that might be contributing to the errors.

Cooling Solution: Ensure that your CPU cooler is properly installed and functioning correctly. Overheating can lead to stability issues and errors during stress tests.

Power Delivery: Verify that your motherboard's power delivery system is capable of providing sufficient and stable power to the CPU, especially when pushing it with PBO settings.

Firmware Updates: Check for any BIOS updates for your motherboard that might address compatibility or stability issues with the Ryzen 7 7600X CPU.

Testing Variation: Run the OCCT CPU Stability Test multiple times with different PBO thermal limit settings to see if the errors consistently occur or if they are sporadic.

Alternative Stress Tests: Try running other stress tests like Prime95 or AIDA64 to see if they produce similar errors. Different stress tests might provide additional insights into the stability of your CPU.

2. 

The PBO Enhancement Thermal Limit and Platform Thermal Throttle Limit are both designed to help manage CPU temperatures, but they serve different purposes.

PBO Enhancement Thermal Limit: This option typically relates to the Precision Boost Overdrive (PBO) settings, allowing the CPU to boost higher under optimal cooling conditions. Reducing this limit could help keep the CPU cooler, but it might also limit its performance potential.

Platform Thermal Throttle Limit: This setting is related to the overall thermal management of the platform, and adjusting it can help prevent excessive heat buildup in critical components, not just the CPU.

If you want to prioritize keeping the CPU cooler and are willing to potentially sacrifice some performance, you can experiment with reducing the PBO Enhancement Thermal Limit. On the other hand, if you want a more comprehensive approach to thermal management for the entire system, adjusting the Platform Thermal Throttle Limit might be a better option.

Ultimately, finding the right balance between temperature and performance may require some trial and error, and it's essential to monitor CPU temperatures during stress tests and real-world usage to ensure they remain within safe limits.

If you continue to experience stability issues or errors despite trying different settings, and if games are unexpectedly closing, it might be worth contacting AMD support or the retailer to discuss the situation and potentially explore the possibility of replacing the CPU or checking for other hardware-related issues.
