Windows 7: Resource Manager Bug: CPU Usage

Resource Manager Bug: CPU Usage



The task jumped to 365 for a brief moment, around <0.5 seconds was way to fast to screenshot it.

And then to 3,565 for a brief moment ( roughly, 3,5xx anyway).

I had it open for a while, was testing a program before and forgot to close it from the second screen. I noticed this happen twice and not since.

CPU: Core2Duo E6600

Anyone heard of this issue ?

Don't worry about it. You probably saw a program opening or something.

I'm obviously not in a panic that it overloaded my CPU or anything...

Just it screws up the CPU Average, as you may have noticed it saying over 200 average CPU.

Maybe it is not screwing up the "CPU Average" and maybe over 200 is the correct average...unless you know something we don't? Just saying... Nothing is free on a computer, every flick of the mouse incurs CPU time, just watching Resource Monitor itself requires CPU time.

Not sure what to make of this post.

I would call you a fool or something, but given your forum title I fear you must have some knowledge so I shall hold off on the insults...

But how does a CPU get 205% average, when I have never seen it go over 100% (100%). One would imagine it follows the general rule that 100% is complete, whole, finished, impossible to exceed.

Where does it show 205%?

Well maybe you should look at what "Average CPU" means.

60 seconds btw, is a long time to a computer that works in microseconds.

It certainly isn't normal, but whether it is a bug or not I'm not sure. I noticed that the file taking the resources was daorigins.exe, so do you play or have Dragon Age: Origins installed?

In the screenshot I attached

@Logicearth you say maybe 205 is the correct value? Then you quoted a help file saying CPU Average is the average CPU usage over a 60 second period. How can 205 be an average % of the CPU Capacity. This means that the CPU Capacity really did jump to over 3000% for a fraction of a second? wow, maybe I should sell my CPU to the NSA? Just to explain, to get 205% average, when a process normally runs at 60-90 over 60 seconds (assuming what? 5 records per second. I would think at least 10, but be safe at 5) 60x5 = 300 records of cpu usage per minute. So my maths suck, but to get an average of 205 when it should be about 70 means one or two of these 300 records must have jumped to a fairly high number (hmm, like 3000?).

So, 205% average CPU usage is a bug surly, when the max CPU usage is generally 100% correct ? So how can CPU usage jump to 3000+ for a fraction of a second, then back down to 80(the real value) without being a bug. Forgive me if my knowledge of Computer Science is failing here, but a CPU cannot magically output 3000+% capacity.

I really am sorry for acting like a douche, but these people with "Seven Pro" and "Seven Guru" makes me think I am the one in the wrong yet I fail to see how. I've been known to confuse people when I explain things, so I really hope this is the case. If not either myself or you are being exceptionally moronic (@Logicearth).

- Back to the question at hand:

Yea I'm not doubting where the CPU Usage is going, I was playing dragon age at that time, and every action ingame started to pause which is why I loaded Resource Manager and noticed this bug. I should comment I found the issue of why DA:O was lagging, which is CPU overheating slightly over prolonged play. Maybe this is the cause of my Resource Monitor bug, or not bug depending if I am being moronic or not.

@Sam86, I guess it was not clear...but did you calculate 60 seconds into your math? For a computer 60 seconds is a very long time, a very long time. 1 microsecond is equivalent to 1 MHz, there is 60000000 microseconds for ever 60 seconds.

You should also note your CPU is throttling itself up and down depending on load. So it can in fact "magically" increase capacity. The blue line represents this throttling.
