Stress tests revealed thermal throttling at 9900k in the system.
Stress tests revealed thermal throttling at 9900k in the system.
You're experiencing thermal throttling on your new system, especially near 84°C. Your friend's setup seems to handle higher temperatures better. There isn't a direct way to change the CPU's maximum temperature limit on most platforms, but you can adjust thermal settings through BIOS or system preferences to allow higher temps.
It seems the system is likely experiencing power limit throttling, not thermal throttling. Review the throttle flags shown by HWiNFO to identify the cause. Verify the turbo power limits configured in the BIOS.
Use HWiNFO to investigate the cause of performance issues. Do not adjust settings until you are certain of the problem. Click the Sensors button to view a detailed list of throttling reasons. If your CPU is throttled by power limits, check the BIOS for turbo power settings. On some Asus boards, these are found under AI Tweaker - CPU Power Management - Long and Short Duration Package Power Limit Set. Adjust both to the maximum value, 4095, unless you prefer different limits that won’t affect your full CPU speed.
