The real purpose of Prime95 is to look for the largest prime number.
Best cpu stress test software#
Prime95 is one of the toastiest pieces of software you can run on a computer. For the vast majority of people however, there are two general-purpose apps that have stood the test of time. Some are highly-specialized and might be suitable if your computer is built for the type of CPU tasks they cater to. There are plenty of applications out there which can help you light a fire under your CPU. Now the question is: Which stress testing tools should you use? The Best CPU Stress Test Tools Stress testing is also useful even without overclocking to test a new cooling system. The short version is that an overclocked CPU has been set to a higher speed than the factory recommendation.Įvery time you overclock your CPU, you should stress test it to make sure that it doesn’t overheat or is unstable somehow. Overlocking deserves to be looked at on it’s own and we have many articles on the subject. Owned over 300 Macs, most second hand repaired andĭonated almost all of them in restored condition.The second reason to run a stress test is as a way to validate CPU overclocking. While standing in the Store, to see if anyone looked up.Ī surprise, for my first time in an Apple Store, yet I’ve Figure I must haveĬaught them in a Zen moment, meditating on iDevices,Īs they were looking into touch-pad/screen products & I could not get a rise out of the Store staff, the only time Store in my state to hand it over (for re-credit to card.)

In fact, as long as there is a command line that is unix based, you could run the ‘yes’ command to stress test a Mac CPU by using this approach.īe sure you quit and kill the ‘yes’ commands when finished stress testing the Mac, as otherwise the CPU usage will remain high and the fans will undoubtedly go on full speed shortly.

Unless you have a valid reason to do this, you’re better off not randomly running “yes”, since it obviously causes performance issues until it stops running.įor some assistance, the video below demonstrates the entire process from start to finish:įor those wondering, this works in all versions of Mac OS X and even linux as well, so you can stress test any Mac ever made this way. If not, there’s probably a typo in there somewhere. You’ll also see all instances of “yes” drop from the process list in Activity Monitor. When finished, in the same terminal window type “killall yes” into the command line to kill all instances of the yes command.
You’ll quickly discover in Activity Monitor or top that the processor is getting hit hard. Yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null &
Either repeat the process by hitting up arrow and return to run another several instances, or throw a group onto a single line like so: That sends one instance of ‘yes’ into the background, but to load up the CPU you’ll want to have more than one running. When ready to stress test the Mac, type the following command: To begin, launch Terminal, and you may want to watch the UI-based task manager Activity Monitor so you can easily observe the CPU load and system resources. This means if you have a dual core Mac with a hyperthreaded processor, you’ll need to have at least four different instances of “yes” running to put full load onto the CPU. Generally speaking, each instances of “yes” will max out a single thread on a single CPU core. To max out the Mac CPU we’ll use the command line tool called “yes”, which basically does nothing except repeat the word “yes” at such speed that it consumes all available processor resources.
