Realtemp reports 100% CPU usage all the time??

I have had this problem for a while now where my OC (system in sig) wouldnt minimize cpu frequency and would stay at the full 4GHz, even though C1 C3/C6 and EIST etc are enabled in the BIOS, i then notice realtemp was reports 100% CPU usage all the time so this would explain the CPU clock never lowering the frequency, despite this the processes tab in task manager doesnt report and programs using the CPU at all. I have AVG Free installed and Malwarebytes Anti-Malware program installed and none of the have detected a virus.

Originally thought the problem was hardware related or BIOS but have done a complete format and fresh install of windows 7 on the OS drive and the problem went away and the CPU operated as it should do. But have got to a point where i have started to install my programs etc and trying to keep an eye on the CPU load via realtemp when i thought everything was fine i check realtemp and the cpu usage is at 100% again. Im not sure why on earth this is happen i have uninstalled all program that were installed between the period of the CPU working correctly and when i noticed that is was being throttled all the time but this doesnt seem to fix the problem. Is there another porgram other than processes in task manager that can tell me what is using the CPU?
 
A bit more progress on this, i have noticed that if i change the power plan from 'Balanced' to either 'High Performance' or 'Power Saving' then the CPU usage drops to normal levels. Any ideas what setting in the 'Balanced' profile is causing 100% CPU usage?
 
Tasks manager reports the CPU usage is around 3%. Have looked in the balance options and the min CPU usage is 5% and max is 100%
 
Yeah, the minimum processor state is 5 and the maximum processor is 100%, this is the same on the performance and power saving plans, but on either of these 2 then the CPU isnt at 100% usage all the time.

I have tried to look through all 3 power plans and cant see anything different between them that effect the CPU usage. Is there any info about that states what the actual different settings are between these 3 plans?. It must be one of the windows updates that courses this, as on a fresh install then the CPU isnt at 100% usage its only when the windows updates start to download and install that the problem starts

I know its not Realtemp giving false reading as the 4 core temps are at approx 60c, and both CPU-Z and easytune6 report 4ghz for the clock speed

Ok here a pic of, Realtemp, easytune6, CPU-Z, task manager processes tab, and the balance plan.....

Notice how EasyTune is recording a slightly lower CPU clock??

In the BIOS i have, C1 state, C3/C6/C7 state, and EIST all enabled.

What do the, C1, C3/C6/C7, and EIST states actually do different from each other then??, and why do some people suggest to have the C3/C6/C7 state enabled and other say not to.

Well i dont think its a hardware or BIOS error, as why would it change when selecting different plans within Windows 7?, i cant actually see what Performance or Power Saver actually does different from Balanced as i have set all the options the same, so it must be doing something different that we cant see or alter??

Yeah I am ruining the latest bios, I think windows must have probably installed roughly 300 odd updates since the fresh install so I'm not willing to install each one individually to find the problem update. Now I might have had this problem for ages but hadn't notice as after I got a stable OC after about a week I stopped monitoring temps and clock speeds and chances are when I did this OC 2 or 3 years ago that windows update that's causing me problems now wasn't even out then. Any ideas on what sort of update would cause a bug in the balanced profile though? So the only difference in settings you can alter between the performance and balanced plans is the min CPU clock speed option?

I'll try your suggestion vashiro, but I think Unclewebb is correct in that one of these windows updated must have effected the balance power plan, I have CE and C1 enabled whilst c6/c7/c8 is disabled in the bios so I don't think there's any error there.

Ok i have tried what you suggested vashiro, i changed the min cpu clock speed to 60% and the max to 90% but the clock speed in CPU-Z didnt change at all. I recorded it on my crappy mobile camera....

Notice how realtemp clock speed and usgae doesnt change either?, and how different the clock speeds are between Realtemp and CPU-Z

PS. sorry about the quality

Your motherboard does not allow you to use C3/C6 when overclocking so all you have to decide is whether you want to use C1 or C1E. With C3/C6 disabled, when RealTemp reports a low value for Load when idle, that confirms that the C1 sleep state must be working. You can choose C1E in the bios if you would prefer to use that sleep state all the time. If you only want to use C1E some of the time then use RealTemp to enable or disable C1E when you are in Windows.

So the GIGABYTE EX58-UD5 mobo doesnt use C3/C6 states just C7 when overclocked? Whats the difference between C1E and C1 state, and should i only have one or the other enabled in the BIOS?

Did you try removing that Gigabyte Easytune nonsense?

I had this problem before i installed ET6, so i dont think the 2are related.


A bit more info i have noticed in msconfig under the services tab there is something listed as,

Intel(R) Integrated Clock Controller Service - Intel(R) ICCS

which at the moment has the status set to 'Stopped' what is this and is it linked to the problem im having??
