Hey guys, Ive been noticing my CPU speed onCPU-z is not what is supposed to be at. SO i looked into it and i tihnk its because of intel speedstep. Yet, in the bios i couldnt find anything related to it to turn it off. Nothing that said c1e or e1st or anything.

Yes i also tried going into power options and put it at max but no diff.

Is this a laptop at all? If so do you have the latest BIOS?
 
Yea some of the manufacturers use different names. I think you should leave it on if you dont overclock. If you using a retail type of computer like dell or something which dont let you overclock, dont mess with the speedstep. It saves you power and its not worth it if you dont overclock your CPU.
 
i can probly help you orange . Give us full system specs , all the way around please.
I have a UD3R w/ i7 and its under advanced cpu options in the MIT as EIST ( enhanced intel speedstep technology) which needs to be disabled as well as c1e.
 
There is a setting on the Motherboard's Bios that should specifically say "Intel Speedstep" Atleast on my EVGA 780i it does. I forget which section it should be under. Probably the System's section. That should be turned off also make sure your FSB is running onthe right frequency as well as the multipliers.
 
Heads up that c1e is different than speedstep. It decreases the voltage when the processor is not in use, while speedstep decreases the clockspeed.

Sometimes motherboard/BIOS manufacturers hide the settings for c1e and speedstep. For example, on one motherboard I had I needed to press F7 in a certain menu to expose the settings for speedstep, c1e, and virtualization. If you can't find the settings anywhere than you probably need to do something similar. See if you can google the problem for you motherboard model.
 
Yes speedstep and c1e are different, but as far as my board goes, i need to disable c1e when disabling eist for it to work . Depends on the board though...
 
You guys have to remember if it is laptop you usually can't disable speedstep it is better for the laptop. When opening cpu-z it throttles down cause it does not require your max cpu use my laptop does this
