This program stress tests Intel and AMD systems for stability using the Intel Linpack.
Similar to 3
A program that simplifies the usage of Intel Linpack. Linpack by Intel is an extremely stressful program that will put even the most powerful X86/X64 CPU in the world at its knees. Load temp under Linpack will be up to 22*C higher than the competing software Prime95. This program will make usage of Linpack easier and more practical.
Keep in mind, use this program at your own risk. By using this program, you agree that neither I nor Intel shall be responsible for including, but not limited to: burned up CPU, fried motherboard, spontaneous room temperature increase, hair loss, or mental stress.
Xtreme Stress Mode (Right-click the "Start" button) allows unprecedented improvement of testing accuracy.
Note: Xtreme Stress Mode may cause the CPU to heat up more than it already does. During testing, Windows may not be usable.
- Works with Intel and AMD CPUs. Tested Intel Core 2(tm) Quad Q6600, Intel Pentium(tm) III 550 MHz, AMD Athlon 64(tm) X2 4200+, and AMD Opteron 165 (Working with AMD processors since v1.7). Also tested on AMD Phenom II X4 940 Black Edition.
- Tested on AMD Turion X2 Ultra ZM-82, Intel Core(tm) i5 470-UM, Intel Core(tm) i7-2600K, Intel Core(tm) i7-3610QM
- Tested on Microsoft Windows XP Professional SP2/SP3, XP Professional X64 Edition SP2. Tested on Microsoft Windows Vista(tm)/7 X86/X64 SP1 by many awesome users like yourself ;)
- Tested by many users on Core i7 9xx, 8xx, i5 7xx, i7 2xxx, AMD 10xxt
Benefits of using Linpack:
- More accurate than Prime95 Small FFTs/Blend (under x64 OS).
- Takes less time to tell if your CPU/RAM is unstable than Prime95 (usually something like 8 minutes Linpack vs 40 hours under Prime95).
- Use the same stress-testing engine that Intel uses to test their products before they are packed and put on shelves for sale.
Benefits of using IntelBurnTest:
- Simplifies usage of Linpack.
- Real-time output of results to the screen.
- Simplifies the process of selecting a test size to use.
- Better appearance.
- Intuitive interface.
- Real-time error checking.
- System status acknowledgement.
- An x86/x64 CPU
- At least 512 MB of system memory. Recommended minimum is 1 GB.
- A modern Windows-NT based operating system (XP and above). Both x86 and x64 are supported.
- Microsoft Visual C++ 2008 Runtime (x86), can be found here.
- Microsoft .NET Framework v2.0 (minimum), can be found here.
How to test CPU and RAM stability (summarized):
You need to extract everything from the archive to a single folder, while maintaining the original directory structure.
- It is best to use a 64-bit OS with the 64-bit mode for the most accurate test result.
- Use the most available RAM possible (IntelBurnTest can now do this on its own automatically). The more memory it uses, the more accurate. However, most people can use "Standard" mode as it should be sufficient.
- Select the run # (should use at least 5 at minimum, no more than 20).
- Start running. Output should look something like this:
Time (s) Speed (GFlops) Result
0.269 31.7314 3.684559e-002
0.260 32.7829 3.684559e-002
0.257 33.1546 3.684559e-002
0.264 32.2425 3.684559e-002
0.266 32.0700 3.684559e-002
Note: The time it takes to run each iteration may vary from test size, and so will the speed and the result. But if the results do not stay consistent, your system is unstable (specifically CPU). Above indicates that the test ran fine so far without instability, but below indicates instability (the Residual(norm) values aren't the same throughout running the test):
Time (s) Speed (GFlops) Result
15.245 43.7434 5.380399e+003
15.250 43.7303 8.675501e-002
15.162 43.9816 3.570760e-002
Note: Instability doesn't necessarily have to happen at the beginning, it can happen in the middle, or at the end. It could be just ONE of them that is inconsistent, but that DOES indicate instability. BSOD or freezing are signs of instability as well.
- As of v2.0, the program will now have real-time result output, as well as real-time result checking for system stability based on the consistency of the outputted results. The testing will automatically stop if the program detects such inconsistency. During testing, you should see an animated flame under "Freeze Test". If at any time during the testing you see it stop moving, it is most likely that your PC is frozen.
- As of v2.1, Core i7 users that wish to test with HyperThreading enabled can now override the number of threads for Linpack to execute
- As of v2.2, if you are having any issues with IntelBurnTest, please enable debug logging by right-clicking the "logging" checkbox to do so, and then send me the debug log file. It would also be helpful if you also send a screenshot of the issue and steps to reproduce the issue.
Caution: Not for beginning overclockers. This program WILL stress the CPU, Memory, North Bridge, and other system components to their highest extent! Make sure your PC is properly cooled and ventilated!
