Performance improves more on battery than when plugged in.
Hey there, so I'm a bit puzzled and need some guidance on this odd situation I'm facing. Some time ago, I was experimenting with ThrottleStop to lower my CPU voltage. I'd been using a -97 offset for both the core and cache, and it performed well – my maximum temperatures dropped from a blazing 97°C down to a much cooler 85°C (a big win for my HP Omen laptop!). Eventually, I went a bit too far and increased the undervolt to around -145. I don’t remember the precise setting before the machine crashed and displayed a blue screen. Anyway, it happened. After rebooting, everything seemed normal except for one thing – the base clock speed was locked at 2.3GHz. My i7 7700HQ is meant to run at 2.8GHz normally and up to 3.8GHz when boosted! Alongside the blue screen, I also experienced issues where BitDefender antivirus mistakenly marked ThrottleStop as a problematic file. After checking online, it seems BitDefender had recently started flagging ThrottleStop in this way. So I removed BitDefender and powered down my laptop to clear any lingering flags, hoping for a clean slate. Everything looked okay then, and ThrottleStop didn’t report any errors. I reset all its settings back to defaults, but the clock speed remained stuck at 2.3GHz. Then I tried resetting the power plan settings, which brought it back to the expected 2.8GHz. That was a relief! After a few more restarts and adjusting FIVR and TPL settings in ThrottleStop (manually applying then resetting), it finally reached 3.4GHz. Now here’s the weird part: when the laptop is plugged in, YouTube videos become extremely slow – they play just a second before freezing and stuttering. But everything snaps back to normal as soon as I unplug the power cable. It’s really confusing. I also reset my NVIDIA settings to default, but nothing changed. Anyone have any insights or suggestions? Thanks a lot! HP OMEN ce-1xx – Windows 10 version 19045 (Home edition) – i7 7700HQ base 2.8 boost 3.8 TL;DR; Used ThrottleStop to lower CPU voltage. It worked well for a while. Pushed the undervolt too high, and the laptop crashed. After restart, the CPU stayed at 2.3GHz. Had issues with BitDefender flagging ThrottleStop. Uninstalled BitDefender. Reset ThrottleStop settings, but CPU remained at 2.3GHz. Resetting power plan settings brought it back to normal 2.8GHz, but boosting didn’t happen. After more tweaks, the CPU finally reached 3.4GHz. Now, YouTube videos lag when plugged in, but run smoothly on battery. I tried resetting NVIDIA settings, but that didn’t help. So it seems things got messed up after trying to undervolt, and now there’s this strange YouTube issue when the laptop is connected!
I’m trying to test the system... it’s functioning properly now. Unexpected restarts and cold starts aren’t causing issues, but a quick reset of the Windows graphics driver fixes it. Video playback is smoother, and I can keep space at 2x without stuttering or buffering.
I picked it up from a PC optimization video, and Zachs tech only grasped it a week back
A restart would resurface the issues, here is my final solution: For other's if they encounter this! Try this: Turn it OFF completely. Unplug it (and take out the battery if you can!). Hold the power button for 30+ seconds. Wait 10 seconds. Turn it back ON. Sluggish Video playback was browser specific so fix was: Turn OFF "Hardware Acceleration" in the settings. Hope this helps anyone else who ends up reading this thread.
This action just restarts the NVram/pram. It's best to unplug the battery before proceeding.
