New Linpack Stress Test Released


Linpack Xtreme is a console front-end with the latest build of Linpack (Intel Math Kernel Library Benchmarks 2018.3.011). Linpack is a benchmark and the most aggressive stress testing software available today. Best used to test stability of overclocked PCs. Linpack tends to crash unstable PCs in a shorter period of time compared to other stress testing applications.

Linpack solves a dense (real*8) system of linear equations (Ax=b), measures the amount of time it takes to factor and solve the system, converts that time into a performance rate, and tests the results for accuracy. The generalization is in the number of equations (N) it can solve, which is not limited to 1000. Linpack uses partial pivoting to assure the accuracy of the results.

Linpack Xtreme was created because Prime95 is no longer effective like it used to be. LinX, IntelBurnTest, OCCT use outdated Linpack binaries from 2012. Modern hardware requires modern stress testing methodology with support for the latest instructions sets.

Linpack Xtreme is available for Windows, Linux, and as a bootable media. The bootable version is considered to be the most superior as the Linux SMP kernel is a lot more sensitive to hardware instabilities than Microsoft Windows. Watch this video for a short comparison of Prime95 vs. Linpack Xtreme.

Make sure to keep an eye on the temperatures as Linpack generates excessive amount of stress like never seen before.

Changes (v1.1.1):
* Added /residualcheck command-line switch. This improves error detection
on legacy Intel CPUs. It is enabled by default on AMD CPUs.
* Added stress test profiles of 14GB and 30GB.
* Added quick and extended benchmark profiles.
* Fixed false positive hardware errors.
* Some minor changes.

I've updated this release with support for AMD CPUs. In addition, Now you can have unlimited runs, disable Windows' sleep mode (always annoyed me when stress testing), more RAM selection, and included (optional) CPUID HWMonitor for temp monitoring.

You could really use some GUI. How much does it matter to have the binaries up to date? It still is same stress test, isn't it?

I like P95 for the same reason you mentioned, it crashes an OC fast and without AVX it doesn't really run as hot (for me) as people claim. I won't be able to use it soon but I'll give it a try at some point. Thank you.
Is the updated linpack harder to pass?

The new MKL binaries are optimized for recent CPUs (AVX-512). LinX, IBT use Linpack binaries from 2012.

There's a good reason for the missing GUI. Users can stress test remotely via telnet/SSH, or monitor remotely. RDP is extremely slow when stress testing.

Yes... especially with the highest problem size (9.5GB of RAM).

Damn, even my own system failed with the new Linpack.

I have updated the release again... better error detection, beeps and stops on any errors.

Thanks for this. Will try it out while squeezing the last drop of performance from my CPU now that my RAM is 100% stable.

With version 0.9.3, AMD Ryzen users can now bake their CPUs like never before. Thanks to .vodka from AnandTech forums for beta testing.
