Linpack by Intel(R) 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.

Benefits of using Linpack:

1. More accurate than Prime95 Small FFTs/Blend.
2. Takes less time to tell if your CPU/RAM is unstable than Prime95 (usually
something like 8 minutes Linpack vs 40 hours under Prime95).
3. 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:

1. Simplifies usage of Linpack.
2. Direct output of results to the screen.
3. Simplifies the process of selecting a test size to use.
4. Better appearance.

How to test CPU and RAM stability (summarized):

1. It is best to use a 64-bit OS with the 64-bit mode for the most accurate
test result.
2. Use the most available RAM possible (IntelBurnTest can now do this on
its own automatically). The more memory it uses, the more accurate.
3. Select the run # (should use at least 5).
4. Start running. Output should look something like this (unless if error detection is on*):

Size LDA Align. Time(s) GFlops Residual Residual(norm)
10000 10000 4 15.979 41.7337 1.012665e-010 3.570760e-002
10000 10000 4 15.119 44.1087 1.012665e-010 3.570760e-002
10000 10000 4 15.216 43.8254 1.012665e-010 3.570760e-002
NOTE: Depending on the memory size selected, the testing size will be
different, so the Residual(norm) values will not be the same if you
ran this test each time with different amounts of memory selected.

5. 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):

Size LDA Align. Time(s) GFlops Residual Residual(norm)
10000 10000 4 15.245 43.7434 1.525878e-005 5.380399e+003
10000 10000 4 15.250 43.7303 2.460366e-010 8.675501e-002
10000 10000 4 15.162 43.9816 1.012665e-010 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. It is
highly recommended to use the most free memory possible for the most
accurate, and quick test. BSOD or freezing are signs of instability
as well.

* If error detection is on, the program will only output the results at the end of the
run, and give a conclusion about whether or not your PC is stable. If it is off,
you will see similar output as above during the testing.
