Does anyone know of a software that increases the load of my CPU to 100%?

I want to see how good my heatsink is so I can make a decision whether to over clock.

Currently I am running nice and cool at 31 cel

you want to run it on 100% for a longer period then just testing software I assume then

Try an @home software like folding@home...

I found one called Prime95

F@H or software that tried to calculate pi or find prime numbers should work.

I use a modded version of Prime95 called sp2004. It has added features to allow you to test specific cores for dual core processors and multi-CPU machines.

Here's a download link: Click Here

And here's a screen cap to show you how to set it to stress both cores at once by launching the program twice and setting the affinities:

Folding@home will put your system under load, but it isnt specifically designed as a stress test. Prime95 and sp2004 were created to stress a system and all of its crucial components.

Cool Thanks! I wiill use sp2004. Thanks for the screenshot Quantum.

Things are looking good!

Check this out:



It's been 100% for a few hours. I think with my current heat sink I can safely overclock

View the full image, the temperature and other details etc are on the bottom

I will have this going for another few hours and see I go but it is looking good

Well, it's been 9 hours and 54 minutes and I am still running nice and cool at pleasant 42/49 cel. I will wait another 2 hours and I will turn it off. It's been 100% load all the way!

Well I cancelled it after 12:30 hours and here are the numbers:




Looking very good

Look in the right corner: 47 cel

Wow.... that's pretty cold! Under full constant load, my CPU heats up to 55/56 C!

yes it's not bad but mine isn't overclocked -- the aim of this test was to find out exactly whether I can overclock with my current stock heat sink and turns out I can They must have put a good heat sink -- quite surprised considering they ripped me off with the memory.

Yeh, I'm running a AMD X2 64 at 2.2GHz now, on nVidia boards, there's an nVidia software thingy that calculates the best values your system can handle without getting unstable....

It clocked on average my system +20%!!!

(And temps vary from idle: 35C to full load: 55C)

Just for the record mine is E6600 Core 2, 3GB DDR-667 and NVIDIA 7600GT 256MB

That temperature for GFX on the bottom, I am not sure what it is, is it the graphics card?

Yes, the GFX is the temperature of your graphics card, I got the 7300GT Silent card, which usually is about 5C warmer then yours. Don't worry about that temp, the nVidia cards are designed to handle temps up to 120C

Cool thx! This one is also silent. It doesn't have a fan. Now it has dropped to 60c so the full load didn't make much difference as it shouldn't....

Just to let you know, that program doesnt stress video cards. It's made to test the CPU and RAM. As for your video card temperatures, they are within norms. Overclocking your CPU/RAM wont affect your video temps by more than a degree or two simply due to a raise in case temperature.

Thanks, I am quite happy with my graphics card anyway
