I'm trying to overclock the GPU on a Lenovo B580 (Model 4377) notebook using Intel XTU. The notebook has an Intel HD Graphics card (the Device ID is 8086 - 0106). Is the GPU compatible with the program? Because Manual Tuning doesn't have any settings for me. It's not greyed out, but it's blank when you click on it. And it doesn't have any sub-tabs (like "All Controls", "Memory", "Graphics", etc.).
If your processor is unlock you can change the settings but most of times mobile processors are locked by the system manufacturer so this may be the reason why you are having problems to over clock your computer.
My recommendation is to contact the Computer Manufacture and confirm if their system can be overclocked. Here you can find the contact information:
