G73JH Processor Stability Qustions

I ended up installing system monitors on the Windows 7 side bar to check out the temps and speeds of the CPU, GPU, and RAM.

Question is for the CPU:

I am using the IntelCoreSeries monitor and I don't know if it's accurate or not, but it seems to be jumping all over the place. Temperature, usage, and the core speed. Temp, just constantly flickers up and down 1 to 2 C. Usage jumps from 0% to 3% when I'm not doing anything. And same for the speed, when I'm not doing anything it just jumps all over the place from 933Mhz, to 2000Mhz, to 1867Mhz, to2133Mhz, to 2267MHZ and it doesn't stay still. I'm not using Twin Turbo but I am using Intel's Turbo Boost (at least I think I am since I have Twin Turbo turned off in the BIOS and in the Power4Gear). I also haven't OC'd it in any way. It should be sitting at 1600Mhz when nothing is going on, but that number doesn't even show up.

Is this the monitors problem? It was working fine about 4 to 5 hours ago. Or is this a CPU problem?

 

i dont think its a problem...i just think some background apps might be starting some prcesses, especially if its 1-2 degree increase that results with a higher cpu frequency. maybe anti-virus is using idle to monitor your computer...its definetely not a problem, happens to me too all the time

 

This is normal activity. Temp will always flicker, its strange, but normal, and usage jumping is often background processes (like AV software) doing its thing.

 

I noticed that the laptop idles at 53C and when I start using it and the MHZ increases, the damn tempature goes down to 45C.... LOL

 

that is physicaly impossible that the frequency increases but temp goes down...monitor seems wrong

 

At first glance you'd think that, but it's not necessarily true. Processor frequency =/= voltage or full core usage.

I'll skip the long explanation about processes, running programs, etc and use the short one:

the i7 has a turbo boost feature that dynamically increases clock speed. The fewer cores used, the higher the frequency. 1 core at 2.6 Ghz will actually pull LESS power than 4 cores at 1.6 [or 1.76, with the twin turbo button on]. Less power draw, less heat. You also only have one core generating heat VS 4.

It all comes down to how much/what is running, and how many cores are being utilized.

 

Ok thanks for the help guys. Was just making sure because it wasn't flickering as much before. Got a little scared. And yes it was background apps. Had like 4 updates going at once.

 

heat generated by processors have nothing to do with electricity drawn, its with thre frequency, if you increase the frequency on almost anything that is able to do it, you will increase the temperature because it vibrates at a higher rate. If you close down 3 CPUs and over clocl one of them then that one will increase in temp. This is just basic electric knowledge everybody know that, or almost. Also the same reason why you should have a good venting system when you overclock

 

Heat generated by processors has everything to do with electricity drawn. The amount of Watt’s drawn. Much less so by the frequency they run at. If what you are saying is true then a light bulb of 10 Watt would give of the same heat as a light bulb of 100 Watt because they both run at the same frequency (50Hz in Europe, 60Hz in the US of A).

Let me show you.
Below you have a couple of screenshots of my 940XM with all 4 cores running and locked at 2.85 GHz. As you can see when the cores have almost nothing to do they draw about 46/47 Watts. This results that the cores hover about 61/62 degrees.

Now I am going to load all four cores to 100% with Intel burntest and see what happens. To make sure the cores would not throttle down and stay at 2.85 Gig I raised the TDP to 95 Watts with ‘Throttlestop’. As you can see the power draw shoots up to about 90 Watts and beyond. But look at what the temperatures do. They shoot up as well.

And a shot what shows you what the temps do when starting and stopping the load on the CPU.

So………………… I am sorry to correct you here Pat but Heat generated by processors has everything to do with electricity drawn. Get your stuff right mate.

No hard feelings I hope huh.

I think i might have wrongfully expressed myself, what i ment is that when the CPU frequency increases (wattage also) the temps would go up. What you are doing here is purpously overloading the system to draw more power. In the case that i mentionned, i meant the natural frequency draws an X amount of power, but if the frequency stays the same, the watts will not change unless your purpously change the system to do it....thats what i meant by that, the processors draw and amount but if you change that amount and increase it it will also increase temp. But he didnt tweak anyhting so it was according to his situation.
BTW, i though an i7 940 has 6 cores?!?
