Way to check max load when running a program?

[Brigs]

Just a quick question, I know that RealTemp will show you the current load that is on the CPU when running something like Prime95 or IBT etc. and then when you stop the stress program the load goes to idle automatically ; But I was just wondering if in RealTemp or a different program I can have it show the max load that the CPU gets to, (kind of like the max and min of temps in HWMonitor, and it saves them). Reason is, I wanted to run a program, and in the background run something like RealTemp that shows the max load that was on the CPU during running the program and have it saved so I can see how high the load on the CPU got while using the program... hope I make sense

thanx in advance fellas ^^

This might help until someone can suggest a better solution:
Windows Task Manager
Performance tab
VIEW tab --> CPU History --> 1 graph for all cores, or 1 graph per core (take your pick)
Stretch the window across your full screen width to increase the graph's time duration

....instant gratification

**edit** At the end of your test, click on WTM display, press [ALT] + [Print Screen], paste image into your image editing program and save the screen-shot.

You must realise that CPU load is a statistical value for a period of time and not a point in time. The CPU can be executing code or idle. For a point in time it can be at max load or idle, for a period of time load is the percent of time code was executed, or, load is the percent of time period the CPU was not idle.

Uh....ignore my previous post.
CoreTemp v99.5 can log your temperatures and cpu load for each core.
The output file is in CSV (spreadsheet) format and logs the following for each core:
high temps
low temps
cpu utilization
time of each log entry

The default is a 10 second log interval.
To change logging options, click OPTIONS --> SETTINGS

easy to see cpu at full load under stress test for xp and vista press alt ctrl and delete together select start task manager and click performance,it will show cpu load and memory usage in a graph

LMFAO, ProfJim is just too funny , thanx for the info guys, Jim I'll definitely download CoreTemp sounds good man


thanx again guys, I didnt know that CPU usage was a statistical value and not actual usage; Learn new stuff all the time!

not exactly what your looking for but OCCT will spit out graphs when its done stressing your system like temp vs load and voltages and a lot more.

I use this one it's kinda old but it will show you load:

Just to clarify. a simple 2 byte code like

loop: jmp short loop

Will show 100% load (on one core) when executed just as an IBT stress. Obviousely it does not put the same "load" on the CPU.
CPU usage or utilization as profJom would be better terms to use.

Re: Way to check max load when running a program?

Hmm... thats interesting Chike, let me ask you two more questions

~So if a small execution of the CPU, (such as the 2 byte code you displayed above), will read as 100% load, what executions manifest load readings of 25 or 50% loads; If it doesnt matter if you are using IBT or executing a small 2 byte code?

~Also, will the program that ProfJim recommended above ,(CoreTemp v99.5), show the actual CPU utilization (i.e. exactly how hard it is working), and not just a statistical representation of "Core 0 is Idle or 100% loaded, no matter how hard the CPU is working."

thanx again for the insight

Re: Way to check max load when running a program?

Normal program do not use the CPU all the time, a program can have two states, suspended or ready to execute. A program enter a suspend state when it waits for user input or waiting for data to arrive, from disk or network, windows message, or other kind of task that is executed by other hardware than the CPU, leaving the CPU with nothing to do.
When ready to execute it will be given CPU time, untill it enter a suspend state, or, if there are other ready to execute programs pending after a period of time (also called time slice, normaly few milliseconds).
While there are programs ready to execute the CPU will be at full utilization.

Prime95 or IBT stress threads for example are codes that do not enter suspend state as all they do are calculations, while the main thread is waiting for user input and other events.

EDIT: No, CoreTemp shows CPU utilization not load.

wikipedia - Load (computing)

Technically, cpu load is not the same as cpu utilization.
We're not computer scientists, we're immature adults who insist on hot-rodding our systems, often beyond reason.

I prefer to look at them as the same thing, mainly because I'm forever mis-spelling utilization (and stability and instability).
CoreTemp displays "load" but it's almost always 100% when stress testing with IBT, Prime95 and probably OCCT and LinX.
RealTemp's single "load" display is consistently at 94% during these same tests on one of my backup systems.

Call it what you want....I don't mind being technically incorrect when we're talking about overclocking and stress testing our systems.

TaskInfo is a great shareware/trialware program that provides a wealth of really useful information about your system and each task that is running.
You can customize the screen display to show only the categories or graphs that you want.

LMFAO, I love waking up in the morning only to find ProfJim has graced me with his presence on the thread

Thanx again for the info guys, I didnt mean to get too technical I was just tryin to get to the bottom of this cpu "load" vs. "utilization" and you guys got me pretty straight forward on the difference now

Thanx for the link for TaskInfo ProfJim, Ill be downloadin' it!

You know I have never had so many monitoring programs, benchmarking and stability programs on my computer in my whole life till I came here LOL, and so glad I did cause I am getting a happy system

Now the real question is... Will you ever find the time to use it? LOL

Re: Way to check max load when running a program?

My bet is that Brigs joins Conners, D-an-W, and Octopuss where he too will devote every waking moment in the elusive quest for stability with high overclocks
