i5 2500k Not Idling to 1.6GHz - Page 2

post #11 of 20
Thread Starter 
Thanks for the responses guys. I was questioning the accuracy of CPU Z to my friend earlier because he said his was reading 1.6 at idle but mine isn't. I also did some searching around the web and a lot of people seem to agree CPU Z is not the best program to measure internal clocks. I'll give both of the programs KuuFA and unclewebb suggested a try and post back with my results in a little bit. Thanks again!

ThrottleStop and RealTemp use the same Intel recommended monitoring methods.

The advantage that ThrottleStop has is it shows you CPU load data on a per thread basis as well as percentage of time in various C States.

When you want to fully understand what your Intel CPU is doing, it is the best tool for the job. It also allows you to adjust the performance of your CPU without having to reboot.

I asked the programmer of CPU-Z why his program reports some of the things that it does. Here was his response.

So, I tried both programs and it appears that my computer is still not idling at 1.6. However, it appears that my computer is running over 20% CPU load, so I'm wondering what the requirements are to be considered "Idle"? Someone else mentioned that anything over 10% is not considered idle, but if that's the case, it appears that my computer NEVER goes into idle then because the CPU is always above 10%. Interesting because as I previously stated in my OP, when I auto clocked before it had no problem downclocking on idle even CPU Z read that it was idle at 1.6. So I'm interested to know why it was able to idle before but not now...?

If I have ZERO programs running, besides of course my AV and Firewall, etc. shouldn't it be considered idle then?

unclewebb, you mentioned earlier that some of my BIOS settings may be effecting the CPU's ability to enter deeper sleep modes? Which settings in particular should I change? This is my first overclock, so I might have not done something right.

go back to offset mode and turn the LLC to medium and put the voltage to +0.010
Small wonder.

I have no problem doing this other than the fact that this generally tends to make my rig run at VCore ~1.35 which I just thought was a little high for a 4.3 OC but then again not every chip is made the same and there are other contributing factors.. but anyways I'll just go ahead and switch back to offset mode.

What exactly does the LLC do? I've had it at Extreme, High, Regular, and Auto before and I don't really know what the difference is?

EDIT: So I changed the LLC and Offset back.. interestingly when I booted the computer and ran a monitoring program it displayed 1.6 for a few seconds but then jumped back to 4.3 so I'm assuming my CPU is never going to "idle"?

You have a significant load on your CPU which is preventing it from idling. You need to open up the Task Manager and check off "Show Processes from all users" and find out what application or applications are loading your CPU.

If your antivirus program is causing this much CPU usage then I would suggest trying something else. The free version of AVAST is very CPU efficient when set up properly.

Here is an example of what a lean Windows installation should look like when the CPU is idle and you are sitting at the desktop not doing anything.

On your computer you might have a single app that is fully loading a single core to 100%. If this never settles down, a rogue app might be stuck in some sort of infinite loop, keeping the CPU busy doing nothing. This 100% load gets shared among your 4 cores which works out to an average C0% of 25%. Fix that and your CPU C0% should drop down significantly to the low single digits.

That's what I was thinking.. I'm wondering why my load is so freaking high as it was never this high the first week or so I had the computer. Bare in mind I built this computer only about 2 1/2 weeks ago so apparently something I installed between then and now has significantly increased my CPU load. In terms of processes, Chrome is always the biggest process running but I'm not counting that as part of the load in this situation because I don't do those tests with Chrome open. Looking at it now as I'm typing this post, it seems that the biggest CPU load is NOD32... as a matter of fact that seems to be the ONLY thing hogging up the CPU. Funny because I had Avast prior to NOD32 but I installed it on recommendation from a friend... looks like I should switch over to a less consuming AV? Or is there a way I can reduce the amount of CPU NOD32 is taking up? Because it seems that NOD32 is the only thing that is causing the load to go over 10% as it is always in the 20's...

Simple solution. Remove NOD32. I wouldn't touch any antivirus or anti-spyware program if it was that much of a CPU pig.

Everyone worries way too much about getting a virus. If you don't open up stupid email attachments that end in .exe and if you don't surf porn sites 24/7 then you can reduce your chance of getting a virus by about 99%. i don't care how good a program is at detecting viruses. If it is sucking up that much of my CPU on a regular basis then it is gone.

Here is a number to shoot for.

This is with Google Chrome, ThrottleStop and Avast running and that's pretty much it. CPU usage over 20% when supposedly idle is ridiculous.

This.

You know, I haven't had an AV installed in a few years now. I'd rather have the resources and not deal with having to disable it here and there just to run programs. I'll drop on avast or avg about once every 6 months and just do a brief scan, but I haven't turned up a single virus since years ago when I was on XP. Only download trusted content and don't click on penis pill ads, and you're generally gonna be pretty good to go. YMMV

Thank you for all your help. I can't believe NOD32 was eating up that much CPU because I just installed it and it's finally idling at 1.6GHz, that was such a simple fix that I never considered... I'm generally pretty safe when I surf the internet and I don't use my PC for anything except gaming and some Photoshop or something, other than that I use my laptop for everything else. Anyways, +rep for you guys that helped!
