The Intel XTU system altered its default BIOS configurations.
The Intel XTU system altered its default BIOS configurations.
You're using an i5-12500H processor and noticed the temperature rising while trying to keep Turbo Boost off. After adjusting PL1 and PL2 via XTU, the temperatures remain high and the CPU is unlocked with incorrect power limits. The BIOS updates didn't resolve the issue. You mentioned constant 100°C readings even when idle and can't modify settings. Have you considered checking for thermal paste degradation or using a different cooling solution?
Check ThrottleStop version 9.6 at https://www.techpowerup.com/download/tec...rottlestop. Press the TPL button and share a screenshot of the Turbo Power Limits window. It displays the available CPU settings. XTU often struggles to consistently apply CPU adjustments. Open Task Manager to see running processes. Process Explorer from Sysinternals is more effective for identifying issues. https://learn.microsoft.com/en-us/sysint...s-explorer You might need too many background tasks, a virus, or a loose heatsink. Ensure proper thermal paste is applied. Consider cleaning dust from your laptop’s vents. When idle, the CPU should use less than 1% of its time in the C0 state handling background work. My computer has many threads and typically shows an idle C0% around 0.1%.
The high CPU usage was linked to the Windows update process. A restart displayed a message saying "Working on updates .. Don't turn off." My laptop was brand new and functioning well before I altered the default Turbo Boost settings. Temperatures reached 85-90°C before using Intel Extreme Tuning Utility. I added ThrottleStop, set stock Turbo Boost (45W to 95W), then adjusted the "clamp" and "lock" options, which returned my CPU to its original default with a locked status. However, this seemed only a temporary solution. After restarting, the Turbo Boost settings reset back to XTU's default again (95W to 115W). When I launch demanding applications or games, CPU temperatures spike to 100°C. Is there a permanent way to resolve this? I reinstalled XTU and discovered an "XTU Default profile" on my disk—maybe editing that file could help. But I can't access the .xtu extension.
It’s likely the new BIOS has raised the turbo power thresholds beyond the standard settings. The 45W Processor Base Power figure is taken at Processor Base Frequency with Turbo Boost off. Setting a long-term PL1 limit of 45W will lower performance, which could explain why the manufacturer increased the limits in the updated BIOS. To check current turbo power settings, uninstall XTU, restart and use HWiNFO. If adjustments aren’t possible in BIOS, you may need to run XTU or ThrottleStop each boot to modify the limits.
The site provides specific power figures for certain Intel Core i5 models. For the i5-12500H, PL1 is 45W and PL2 is 115W. The i5-13500H has TDP values of 95W UP and 35W DOWN. These numbers differ from what you expect, possibly due to changes in Intel's specifications. Regarding BIOS settings, "restarting BIOS" or disabling Intel Dynamic Platform and Thermal Framework usually means adjusting thermal management features to lower power consumption. The exact steps depend on your motherboard model—check your system documentation for guidance.
Confirmed the 45W was the Base Power for i5-12500H. Shared a forum user's experience with matching settings. Noted confusion over PL1 values online, thinking XTU altered them. Still want to adjust Turbo limits but haven't found clear ThrottleStop guides for undervolt protection. Are reducing PL1 and PL2 enough? Any other options to check? Also, did enabling Performance Boost mode affect ThrottleStop compatibility?
