i7 920 running at 2.79GHz continiously

C

guys my i7 920 is constantly running at 2.79GHz from 5th day of purchase even if no process is running and CPU utilization is 1%
is this some thing to do with windows or what

Ill say something very obvious....check if speed step is enabled in the BIOS...btw, why 4GB memory ?

C

there iss nothng running on the machine

Download LinX and stress it. The speeds should go up.

C

I did the stress testing using linX the speed goes up from 2.79GHz to2.8
the cou utilization goes 100% memory utilization is 95%
But it does not return to 2.7Gz stock speed!!

That screen shot clearly shows you cores are not on load. What is the issue now..? Or I did not understand..?

the speeds should step down at idle (speedstep?) and even at load it should run at 2.66GHz.

cooldude what is the wallpaper you are using
can u share its url.

Dude,

From the screenshot i can tell that you must immediately uninstall the 2nd widget completely. The intel i7 turbo booster. I had the same installed when i got my new pc and found that it increases the processor speed whenever necessary. But the disadvantage of that it is not very efficient and heats up the CPU; also this widget consumes CPU power when it starts working.
So uninstall the widget completely, and go to msconfig and disable it from startup as well if it still resides there.

Hope that helps. Try the steps mentioned above and report back.

Cheers,
Cosmos

P.S. Why only 4gb ram!!! U r not utilizing the tri-channel power of i7 dude.

C

@Cosmos: I Uninstalled the widget completely disabled it from my startup but cpu-Z still shows
core speed 2800MHz

Could u explain it??
i bought Only 4GB becoz my budget way exceeded way abv the limit
Actualy it was 45k w/o monitor
but i bought 55k w/o monitor

One of the features on the 920 is triple channel memory. To tell in a very crude way, you need RAM in multiples of 3, infact the sticks should be in multiple of 3. So its 3GB (1x3) or 6GB(2x3) or 12GB(2x6) and so on...

not a big difference between dual and tri channel in practical apps anyways...

^^
The MCH sees the three DIMMs as one large module, and the data channeling is quicker. Throughput between the CPU and RAM goes up.

R

but how much does it make a difference, in real life? not synthetics..

Not much. Here is an article.

Guys Back to the topic Yaar it is still at 2800Mhz in cpuZ

OP:
Do these three things. And lets end this.
1. Download LinX.
2. Post a screen shot of the first CPU-Z tab with LinX running in the background.
3. Post a screen shot of the first CPU-Z tab with LinX NOT running in the background. The system should be on idle.

C

These r the screen shots u requested

Try to reset the BIOS once from the BIOS setting.

Sam/Azad/Rahul:
Could you guys please tell him your system setting from the BIOS, specially the automatic settings.

will post tomorrow morning. however mine is a now ancient P4. any use? :smile:

^^
Sam Gamer I guess has an i7..!
