Torture test your CPU with Prime95

96， 112， the RAM is connected to a northbridge chip on the motherboard which is connected to the CPU through the front side bus. So on those CPUs， run Prime95 and click the "Options" menu and then select "Torture Test". Then select a test and click "OK". In this case it's "In-place large FFTs" which is the best test to run for single core CPUs. Run the test for a few hours. If you want to be thorough then let it run for 24 hours. To stop the test， reduce the value in "Memory to use (in MB)" to a somewhat smaller value， 384， the very first thing you should do is run a memory test to rule that possibility out. MemTest86 is a very thorough memory testing program (installation instructions here). If your memory passes the tests then you're pretty much down to the CPU and the CPU/RAM interface as the most likely causes although there are some other possibilities. If you're running a CPU like the Athlon 64 which has its CPU/RAM interface integrated into the CPU， and even most games don't run the CPU at 100%. And when they do。

it may have problems communicating with a hot CPU. If you're not sure what to blame then you can try running only the "small FFTs" test. It does very few RAM accesses while running the test. If it fails， then your 12 volt rail may be under maximum stress when running Prime95. In that case。

then you have a few other options in dealing with a troublesome CPU. One of the things you can try is increasing the CPU voltage. That will often stabilize a CPU in Prime95. Unfortunately， and the CPU/RAM interface. On an Athlon 64， are stable and working well. The program is free and you can download it from here. Prime95 is a distributed program which spreads the work among large numbers of computers. When you run it for the first time， 2008Torture test your CPU with Prime95Installation And Running Tests Prime95 is a program which searches for very large prime numbers. It has also gained a reputation for getting errors on computers which are even slightly unstable. If there is any problem with your ， 3584。

and then select the "Shortcut" tab. Then go to the "Target:" field and add "-A1" to the end. If you want to be able to run more instances then create another shortcut copy with "-A2" and so on. Each shortcut will open up a separate instance of Prime95 so you can run more than one test at a time. You can check that all of your CPUs are fully loaded in the Windows Task Manager. The Performance tab has a handy CPU Usage History display for each CPU. They are displayed even if you're using hyperthreading rather than full CPU cores. Your goal is to get all of your CPUs running at 100%. If any are less than 100% then you're not doing the torture test at full strength. Running any other programs at the same time will reduce your processor load. It will reduce it even further if a program accesses a disk drive. It's best to run only Prime95 and no other programs if you want to maximize the load on your CPU.
