Overclocking help

[Nicane]

I used to be able overclock my CPU quite a lot, from 2.83 GHz -> 3.6 GHz. But now, when I am in the Windows environment, (and I have a program to show me) it tells me the speed is 2550 MHz, but then after a second or two, it jumps to 3610 MHz. It used to stay at 3.6 GHz, but now it's all over the place, jumping UNDER the stock speed -> above stock speed. What would be causing this? It stays fine in the BIOS and reports the nice 3.6 GHz, but as soon as Windows starts, it jumps. I figure it's a program, but I removed the program that seemed to cause it. Any ideas?

Thank you.

your cpu slows itself down when not in heavy use to save power and heat.

as soon as your cpu needs to do something, the clock speed rises to max value.

you can control this behaviour in your bios - i forget the exact setting. let me reboot and have a look...

 

[Nicane]

It doesn't do that though. Like when I am running games or compressing or something, it still does this. Even when it's at 50% usage.

go to your bios and turn both EIST and C1E off - they'll probably be buried in a sub-sub menu somewhere.

EIST = enhanced intel speedstep technology
C1E = enhanced cpu state 1

 

[Nicane]

Ohhhh thank you. I don't have an option for EIST, but C1E was enabled. I don't know why I enabled that. But thank you very much. Now it's staying at a nice and even 3,613 MHz.

If you have EIST enabled then in your Power Plan you will have two added entries for CPU processor. A minimum and maximum speed. This will make Windows 7 (and maybe even other programs) adjust CPU speed according to what you set.

If you set both to 100% then it negates EIST.

glad to be of help

Why would you want to disable this CPU life prolonging feature?

If you are running something that needs the power, the power will be there. When the power is not needed, the CPU will cool down, prolonging its life span.

 

[Nicane]

It doesn't do that though. It just jumps back and forth every second or two, even when I'm not doing anything. And who cares about the life? Might as well use what I can with it and buy a new one in a few years when this one is outdated anyway.

Another reason is that when overclocking the speed step and C1E halt state can cause instablity with the overclock.

Sometimes you can run them when overclocking other times it just won't work. No doubt they are handy features for saving power.

I am going to boot later today. I will check my settings. I have something set that works nicely for me. My machine idles at 1.67 and peaks at 3.2, runs mostly at 2.67. No wild fluctuations.

Not much of an OCer and I did struggle to get it right. But I really like what it does.

 

[mickey megabyte]

personally i have my 3 ghz chip overclocked to 4 ghz, and i leave both eist and c1e turned on.

it all works fine on my motherboard, my chip runs at 2.6 when idling, but jumps to 4 when i need the extra oomph.

i don't slow my chip to prolong its life, it's the fan speed/noise that i am concerned about.

I leave the SpeedStep functionality enabled to reduce my power consumption. No sense sucking extra power when the PC is at idle.

 

[Nicane]

Good point. I don't pay for electricity anyway. ~chuckles~

Somebody does. If it's your parents, then by paying more for electricity it's less money they have to buy other things...even stuff for you.

 

[Nicane]

Yes, but my dad makes plenty of money. And I buy my own things. So really, nobody misses out on how little it really costs for electricity. Compared to what they leave on, anyway.

 

[TGSoldier]

I disable those features.... Maximum performance 24/7!

This life prolonging issue. Come on. You are going to change your CPU in the next couple of years anyway.. It's not like it's going to cut it's life span short by 2 years or something..

 

[pparks1]

I disable those features.... Maximum performance 24/7!

Maximum performance 24x7. But what if you only need that power for 7 hours a day? Constant performance = more energy use = more heat in the room = more cooling to keep it comfortable = more noise all the time.

 

[TGSoldier]

I have the cooling down... My room also has air conditioning.. My music is playing most of the time so I don't hear the "noise". If I do hear it it does not bother me...

Come on.. My office is IN the server room.. You really think a little overclocked CPU is going to affect me?

 

[Antman]

Yes, but my dad makes plenty of money. And I buy my own things. So really, nobody misses out on how little it really costs for electricity. Compared to what they leave on, anyway.

So, where do you work?

I will not address your mistaken idea about the "low cost" of electricity.
