Linpack Stress Test is a small console front-end with the latest build of Linpack (Intel Math Kernel Library Benchmarks 2018.3.011). Linpack is the ultimate CPU stress testing software available today - best used to test stability of overclocked CPUs. Unstable systems tend to crash in just a matter of minutes by running Linpack.

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.

I created this project because LinX, IntelBurnTest, and OCCT use outdated Linpack binaries. Make sure to keep an eye on the temperatures as Linpack generates excessive amount of stress.

Linpack doesn't work well with problem sizes above 35000 (9500MB), and yet it is not documented in LinX or IBT.

v0.3 - Added support for AMD CPUs.

Poslednje verzije će biti ovde: (mada ima i na drugim forumima, trenutna verzija je 0.6)

Odgonetnuo sam zackoljicu koja me kopkala mesecima... Sa novijim verzijama LinX-a (0.7+) bi mi se desavalo da residual vrednosti budu razlicite a test uspesno prolazio uprkos tome cak i na stock frekvencijama https://forum.benchmark.rs/showthre...-lpx-3200mhz&p=5025977&viewfull=1#post5025977
Vidim da se i sa Linpack Xtreme 0.9.3 isto desava drugim ljudima https://www.techpowerup.com/forums/threads/linpack-xtreme-released.247335/post-3899168 uz odgovor da je to normalno na novijim Intel CPUovima https://www.techpowerup.com/forums/threads/linpack-xtreme-released.247335/post-3899247

Konfa iz potpisa. GFlopsi variraju jer koristim komp tokom testa :D
