However, while Prime95 was originally intended to find Mersenne prime numbers, the torture test that is included in the program (which helps ensure correct operation when searching for Mersenne prime numbers) has been adopted by many hardware enthusiasts to help them stress test their processor (and memory)-especially after overclocking their CPU and memory.Īida64 is another CPU stress test tool that a lot of users prefer over Prime95.
Prime95 was developed by GIMPS, a computing project aimed at finding new Mersenne prime numbers (any prime number that can be the result of the equation: 2 n − 1). If you’re looking to stress test your CPU, whether to check how stable your processor is running after overclocking it or to check and see if there is a cooling issue on your CPU, the tools listed below will help you get the information you need. With HWiNFO64 you can track temperatures and other information on your CPU, GPU, RAM, and motherboard, as well as track fan speeds, component loads, and plenty more. HWiNFO64 is one of the more advanced hardware monitoring tools out there as it allows you to monitor multiple core components in your system.

Like Core Temp and GPU-Z, MSI Afterburner is free to use. Along with being able to provide you with much of the same information that GPU-Z offers you, MSI Afterburner will also let you overclock your GPU, set custom fan profiles, run in-game benchmarks, and even record gameplay video or take in-game screenshots. However, it dubs itself as being a graphics card ‘utility tool’ because of all of the other features it comes with. MSI Afterburner is another graphics card hardware monitoring tool. With GPU-Z you can monitor the temperatures and load on your GPU, as well as your GPU’s clock speed, onboard memory clock speed, fan speed, and the amount of memory being used among other things. GPU-Z is similar to Core Temp, except that instead of monitoring your CPU, GPU-Z will, obviously, monitor your GPU. And, there are a few different handy plugins available for Core Temp that expand its capabilities, including an add-on that allows you to sync your RGB lights to the temperature of your processor or to its load, and a remote server plugin (for remote access), However, for AMD temperatures it just shows a single temperature for the entire CPU.Ĭore Temp also provides you with some basic info on your processor and tells you the voltage and frequency your CPU is running at as well. If you have an Intel processor, Core Temp will also provide readings for the temperature and load on each individual core on your CPU. Core TempĬore Temp is a nice lightweight CPU monitoring tool that will provide you with real-time temperature readings and load percentages on your processor.
The following tools can be used in unison with the benchmarks listed below in order to give you more information while you benchmark your computer. While running stress tests on your system, it’s a good idea to monitor your system’s temperature and load levels. Which Stress Test Tool Should You Use? Hardware Monitoring Tools to Use While Running Stress Tests For non-base-2 PRP tests, there is a new option to run each iteration twice and rollback if a mismatch occurs.5.Because PRP tests are highly reliable, we now offer the option to do PRP tests instead of Lucas-Lehmer primality tests.PRP tests now support a type of low overhead error checking that almost guarantees correct results even on flaky hardware.Like LL tests, PRP tests now support shift counts to aid in running double-checks.GIMPS has a new sub-project - finding (probable) prime Mersenne cofactors.This replace LL testing as the default work type. More robust implementation of Gerbicz error checking in PRP tests.Modified torture test dialog box with new options and better understanding of the L1/L2/元 cache hierarchy.
#PRIME95 CPU STRESS TEST WINDOWS#
This is the 64bit version for Windows 7/8/10 64-bit. The benefit of this version is that it is multi-threaded and will automatically manage worker threads to fully stress all cores of your CPU. Usually Prime95 will detect an error within a matter of minutes if an overclock is not stable, however many people like to let the system "burn-in" overnight to ensure long-term stability. There are several options allowing the stress test to focus on the memory, processor, or a balance of both. For overclockers, Prime95 has a feature called "Torture Test" that allows maximum stress testing on the CPU and RAM.
