CPU i7 7700hq runs at 2.69GHZ under load, while base speed is 2.8GHz and boost reaches 3.8GHz.
I'm using a gaming laptop, specifically the Legion Y720, and have been experiencing a noticeable drop in performance. I've switched to Linux for my workflow and reinstalled Windows 10 just for gaming. I've configured my power plan to high performance with full power settings. Since my battery is depleted, I'm using the laptop as a portable setup with an external display, keyboard, and mouse. While playing games like Siege, Overwatch, or CSGO, my FPS consistently falls well below average. I ran benchmarks on XTU and saw no thermal throttling. However, my CPU remains stuck at 2.69 GHz regardless of settings. Hwinfo reports base speed as 2.8 GHz, but the turbo boost is enabled. I'm puzzled by this issue and have attached a Hwinfo report for reference. Please let me know if any additional details would be helpful. Thank you ahead of time.
@Blakeinstein Consider testing ThrottleStop. https://www.techpowerup.com/download/tec...ottlestop/ Many Lenovo laptops employ various throttling techniques. Share some images of the ThrottleStop interface. Look at the main screen, the FIVR window, and the TPL window. Verify the ThrottleStop - Log File setting and play a game for at least 15 minutes. After testing, close ThrottleStop so it can finalize the log file. It should appear in your ThrottleStop / Logs folder with today’s date in its name. Include this file in your next update. During testing, exit HWiNFO and avoid using Intel XTU. ThrottleStop offers special tools to address throttling issues. Intel 7th Gen mobile CPUs support Speed Shift Technology, yet many devices from that time didn’t activate it properly in the BIOS. When enabled, you’ll notice SST highlighted green on the main screen of ThrottleStop. If not, open the TPL window and review the Speed Shift settings. Click Apply to see the recommended min and max values. The Max should be set to 38, which is your maximum multiplier. I believe the Min for a 7700HQ is 8. Confirm OK. After enabling it, check the Speed Shift - EPP section on the main screen. Tap the EPP value next to “EPP” to adjust it. Setting it to 0 lets the CPU run at full speed regardless of workload. Most laptops use 80 or 84, allowing throttling when lightly loaded but still permitting full speed under demand. Raising EPP to 128 or higher may hinder peak performance. A high EPP setting could help on battery mode. Speed Shift likely caused the issue with your 7th Gen model, though other factors might be involved. A log file and screenshots should resolve the matter. It’s possible Linux manages Speed Shift correctly while Windows 10 does not. With Windows, only the BIOS can activate it; if it isn’t detected, the system won’t try to use it even though all Intel CPUs from the 6th Gen support it.
Initially glad someone replied. Right now I haven't turned on SST yet, but I've set EPP at 20. Power saving isn't my priority since I don't have a battery left, but I chose 20 for safety. I'll go back after some tests, but it seems to be working as expected. Thanks!
If you don't see a lock icon near the PROCHOT Offset setting in the Options window, adjust it to raise the temperature during thermal throttling. Intel's default is 0, while Lenovo sets it to 6 which may lead to early throttling. Also consider clearing the BD PROCHOT box. Share some images. There could be additional steps to boost performance or reduce heat.
