CPU Underclocking

post #1 of 17
Thread Starter 
I cannot for the life of me figure out why my CPU wont run at full speed.. speedstep is off and being a laptop there isnt much else I can do in the bios. Power plan is set to high performance in Windows and temperatures are fine.


Alienware M15x laptop fyi.

Any idea what the heck is going on? Hopefully its an easy fix and I'm forgetting something..

Depending on what clock speed you're running at up the core current in the bios, I have to run 300 for 5 GHz but you might need less. The CPU is trying to keep the power draw down so it will automatically lower the multiplier to maintain it.

This is a Alienware M15x, should've mentioned that.. I basically have no control over any CPU settings other than speedstep.

I just missed this is a laptop the picture was small and I looked at your sig rig instead. I have a 720QM but it's a dell and the bios features are limited so I don't know about bios settings. Check the power settings to see what the max processor usage is set to it should be 100%.

Edit: I'm on my m15x right now I don't think it's bios related, it has to be the processor power settings in the power plan.

i think that
just if you plugged it in power and put in high performance it runs ~ in high speed if you unplugged it the management engine lowers the multilayer biggrin.gif:D
sorry for that

If its like mine it should have a "Turbo boost" feature which you can change in the BIOS besides that you should set your Watts to the highest if you haven't already.

Make sure you don't have stealth mode on (the little dial in the top right of your keyboard) sometimes I push it while I'm cleaning it and games run in half the frames.

Everything is set to 100%.. and speedstep is off in the bios to. Should be running full speed while using OCCT. :\

This is what should be causing it under advanced power settings. One setting for AC one for battery.
448

Edit: If this isn't it then I'm out of ideas for now.

Edit #2: You could try resetting the cmos I had to do that once. Can't remember if there's a default button in the bios but the battery is behind the cover just pop out the little plug connected to it since it will be wrapped in black plastic wait and then plug back in.

I just reset the CMOS.. battery was super easy to get to and now its running at 2.7Ghz with turbo. Thanks for the help! smile.gif

EDIT: Now it only shows one core in task manager..
