CPU runs slower when temperatures drop
CPU runs slower when temperatures drop
I upgraded to a cooler from Cooler Master and saw significant improvements in performance. With the original cooler, temperatures spiked quickly and the clock slowed down, but after installing the new one, both temperature and speed stabilized. The system ran smoothly at 3.8 GHz with 59°C and 3200MHz, then dropped to 3.3 GHz and 79°C under stress testing. Your setup includes a B560 motherboard, 32GB RAM, and a Ryzen 9 7950X processor. Are there specific settings you'd like adjusted further?
The cooler replacement wasn't required. A temperature of 79 degrees during testing is completely typical.
The CPU would only begin throttling once temperatures reached over 90°C, which didn’t appear to be a concern based on what we observed. The cooling solution was just a slight improvement; the main advantage lies in the improved airflow direction for most setups. It should definitely suffice for that particular CPU. Also remember, the overall case design plays a role—fans and vents must be properly arranged, especially if fresh air isn’t available, or it won’t cool effectively. This is something many people overlook but is crucial for optimal performance.
Tested it and after a moment it dropped to 3.9 Ghz then fell to 3.5 at 55 and 51 degrees respectively
The stock had some fluctuations anyway. Still, I was counting on the new cooler fixing the clock speed problem.
You haven’t looked into the VRM temperatures yet, have you? It’s possible they’re overheating despite the heat sinks and the 11400’s power usage. Also, does your CPU use less energy as the benchmark runs longer? That might point to elevated VRM temps, at least based on what I understand.
Check ThrottleStop version 9.6 at https://www.techpowerup.com/download/tec...rottlestop. Capture main window screenshots, FIVR and TPL windows. Include a picture of the Limit Reasons window during throttling. Intel CPUs may reduce speed for various reasons—no need to guess. They log performance data and throttling causes in ThrottleStop’s Log File. Close ThrottleStop after testing to finalize logs, which will be saved in your ThrottleStop/Logs folder. Some B560 boards don’t allow setting maximum turbo limits in BIOS for non-K series CPUs; check BIOS settings but they likely don’t work. Voltage regulator throttling is another possibility.
I'm not sure what occurred, but everything is working now. I restarted Windows and it remained on a black screen for about five minutes before restarting. I forced it to shut down by holding the power button and then turned it back on. I ran another stress test with the same program, and it maintained 4.2 Ghz throughout. If there are any further changes, I'll let you know. Thanks for your assistance.
