The CPU isn't reaching its full clock speed.
The CPU isn't reaching its full clock speed.
The laptop's performance has been stable until recently. It runs smoothly with the i7 1165G7, but recently it's only reaching 4.1GHz instead of the expected 4.7GHz. I've adjusted many BIOS settings and run stress tests focusing on just one or two cores to prevent power issues. Even with ample temperature and power capacity, it still can't exceed 4.1GHz. Any advice?
Lenovo requests the return of the laptop within seven business days for repair... this isn't feasible since it's my sole school device.
Have you installed any firmware updates? Are there pending UEFI updates? Verify the clock speed using tools like HWInfo. Check if Intel XTU is compatible and attempt some adjustments. It seems XTU is mainly for high-end desktops, but older versions might fit. Reset all UEFI settings and ensure your battery is healthy with the original adapter connected. Adjust power plans in the control panel. If possible, look for a utility that limits clock speed (around 700 MHz) – it could boost performance. Running at such high speeds may cause throttling and limit multitasking. "Physics sims" won’t allow it, but you might find a workaround.
HWInfo displays the same result I saw in that tool, but altering the value to anything other than 0 restricts it to 2.8GHz battery health. CMOS and UEFI reset resolved an issue with one of my charging ports that wasn’t functioning, though the CPU still caps at 4.1GHz. I discovered an older Intel XTU version, but it triggers an error about missing drivers and prompts for the latest update.
Share some ThrottleStop images with the FIVR and TPL windows. Verify the MMIO Lock box in the TPL window. Capture a ThrottleStop screenshot during the TS Bench - 1 Thread test. Aim for a shot when the multiplier is close to its maximum. The top speed is 4.70 GHz for a single core when active. https://www.intel.com/content/www/us/en/...tions.html. If background Windows tasks are heavy or you're gaming, full turbo won't be visible. Check the BIOS and use ThrottleStop to ensure core C states are enabled. A common myth is disabling C states; non-K CPUs must have them enabled for proper Turbo Boost.
The sole choice is to perform a netboot, though it can be tricky. It may fail sometimes, and an active Ethernet connection is required. Arch Linux supports netboot.
