Hi, your friend's Lenovo Legion Y520 with an I7 7700HQ seems to have the potential for higher speeds, but the real performance is much lower than expected. The Cinebench score is around 3342, far below the expected 4200. The CPU only reaches about 3.5GHz on a single core and 2.7GHz on all four cores. Temperature stays within a safe range of 67-68°C. The BIOS doesn't show any Turbo options, and the Intel XTU reports multiplier values of x34 for all cores and x38 for a single core. Power settings are set to full performance with no minimum or maximum limits. What could be causing this discrepancy? Any suggestions would be appreciated.

We should consider our next steps carefully and plan accordingly.

You can't do anything about it to my knowledge. The limit is most likely set through hardware.

It might reduce performance, though XTU usually warns beforehand. Try running cinebench with XTU monitoring to check the results.

2.7 is below the standard requirements, which might affect thermal performance. I wouldn't rule them out just because 68°C isn't a problem, but it's far from ideal. Some aftermarket thermal paste could help if you're comfortable disassembling the device. Review the BIOS for power restrictions. Turn off features like C1 and C3—anything that aids power saving or quiet operation, including battery life. Not sure if your BIOS supports these adjustments. Intel boards have a feature that limits power consumption while increasing performance. Ensure Windows is set to high performance mode and plug the laptop into a wall outlet. Always use a solid, flat surface or a cooling solution for the laptop. These cooling methods used to be just for show, but with modern power-hungry systems keeping temperatures down, it makes a noticeable difference. So: BIOS, thermal management, window settings, and avoid undervolting. I only note this because some online users suggest it, while others report their boards failing or behaving erratically after changes (such as fans stopping completely, leading to permanent damage).
