Intel i5-3337U TurboBoost Stopped Working

[Niel Mistry]

My Intel i5-3337U clocked at 1.80 GHz was working amazingly, turboboosting up to 2.50 GHz until a few days ago when I noticed that the clock speed doesn't increase to anything higher than 1.50 GHz. I don't think I've installed anything in the meantime, and I'm not sure if it's the BIOS or the OS that's causing this limit to be enforced.

Any ideas on how to fix it?

Hi there!

What make and model is your laptop? And could you include a screenshot of what CPU-Z is showing you?

Cheers!

Hi again,

Your multiplier is actually 17 instead of 18 and you said it even went down to 15..
Any chance you set your power plan to power saver? in that case the cpu downclocks itself (speedstepping) to save power and may only increase when really needed
Try setting it to high performance and check with cpu-z to see if there is an increase. Thing is laptop bios versions usually don't let you modify any speeds so I doubt you did anything there

Cheers!

Hey, it appears that task manager was showing the wrong frequency because it was in high performance and CPU-Z showed the turboboost functioning. I did some research and the cause of the Task Manager error is that I have Hyper-V enabled on my computer
Thanks for the help
