BD PROCHOT encountering performance problems within the game.
BD PROCHOT encountering performance problems within the game.
Ensure you open the Options window, adjust PROCHOT Offset to 0, and confirm the Lock PROCHOT Offset option. This stops software from altering the thermal throttling temperature settings. Your screenshot confirms you’ve completed this step. If you wish for ThrottleStop to control CPU usage, activate it each time you boot up your computer. It’s best to keep ThrottleStop running, positioned in the bottom-right system tray or notification area for minimal resource consumption. The Task Scheduler can automate its activation upon logging into your Windows account. See the guide here: https://www.techpowerup.com/forums/threa...st-4749675. The BD PROCHOT setting must remain enabled. Dell’s throttling levels are too high and unnecessary. Modify the MSR turbo power limits to regulate power output and heat generation. The design that forces a 4000 MHz CPU down to 1300 MHz during gaming is questionable. Review the Speed Shift box in the TPL window to ensure ThrottleStop tracks the Speed Shift Max value consistently. Have you tested your setup by running a game with power limits set to 60 and 80? Those values sound reasonable. Limiting power in this way may help balance heat management against performance. Does your laptop run smoother at near-rated CPU speeds? I usually skip checking the Lock box in Power Limit Controls. Leaving it unlocked allows changes without a reboot, but locking it is often more cumbersome. Locking the MMIO power limits is generally advised. Only lock MSR power limits if your system frequently alters them—most devices don’t do that. Regardless of the feature, your CPU will still reduce performance to prevent overheating. ThrottleStop cannot disable thermal throttling.
after adjusting the power limits to 60 / 80, the performance became more stable. temperatures remained good. I observed the CPU reducing its clock speed to around 3.6–3.7 GHz when temperatures hovered between 80–85°C. When temps dropped below 75°C, the CPU increased to 4000–4100 MHz, which is ideal. I also have some details to share: I own a Dell G15 5510 and another G15 5511 with an i7 11800H. I noticed that the Dell doesn’t properly throttle the i7 11800H, even though it lacks a BIOS-based solution. The temperatures are extremely high—nearly 100°C continuously during CPU-intensive games. Additionally, I’m curious why the G15 5510 has a BIOS throttle while the G15 5511 doesn’t. Is there a way to disable BIOS throttling in the BIOS settings?
It's uncommon for a laptop to include that BIOS setting. Dell laptops typically limit performance rather than allowing higher speeds. Modern machines tend to overheat during gaming, though the exact throttling methods remain unclear. I suspect Dell's support staff never learn such details. To manage power limits, use ThrottleStop and adjust the Speed Shift Max value for better control. For extra performance, consider setting PL1 to 65W instead of the default 60W.
I discovered some unusual behavior. In the Dell power management software, there are several thermal and performance options. I changed it to Ultra Performance, but restarting brings it back to the Cool setting. When I switched to Optimized, it also reset to Cool. In Windows Power Management, only the Balanced mode is available. In the BIOS under power settings, I found identical settings. After saving and restarting, the BIOS still returned to Cool. Only when I activated G Performance Mode (by pressing the key on the keyboard) did Ultra Performance activate. This seems to resolve the BD PROCHOT issue—it appears not due to a faulty sensor, but from some software interference. Any suggestions? Should I reinstall the BIOS and reset Windows? Also, using Windows 10, should I upgrade for better compatibility? Thanks a lot for your help! Edit: (I noticed something odd in my BIOS overview) Check this: the CPU max clock speed is listed as 2.2GHz, but it should be 5.0GHz. Any thoughts? Please add more BIOS screenshots for clarity.
