Blender is quite good. It's highly parallelized, receives optimizations directly from the CPU manufacturers, and uses all of the latest instruction sets so it puts a good, heavy load on the CPU. Memory usage is also scalable depending on the scene you render

s-tui has stress built-in, so you could run some stress tests with that.

For general stability most of the popular windows programs are available on Linux.

prime95 - I build it from source, but precompiled binaries are available - GIMPS - Free Prime95 software downloads - PrimeNet
linpack - Intel® Math Kernel Library (Intel® MKL) Benchmarks Suite
y-cruncher - y-cruncher - A Multi-Threaded Pi Program

Depending on your distro, you should be able to find those in the repos.

I'm curious why you don't stress test on Linux first. I don't fully understand why this is but I've always understood that Linux is more sensitive to bad overclocks. As such if you will find a fault it will pop there first. I've seen countless things over hte years around the net about stable OC on Windows bites it on Linux. Again I don't understand why that is.

Hey Tadaen
I think how overclocks run on Linux depend a great deal on what kernel one uses. I'm currently running 5.12.12 with CPU set as "Core 2, Xeon" and Governor set to "Performance" with realtime scheduling and low-latency and my air-cooled i5 OC'd mildly to 5.0 GHz runs like an SR-71. If it was much faster I could time travel

Hi ,
mprime is an excellent way to stress CPU and memory in linux. You can choose a type of torture test to run.

1 = Smallest FFTs (tests L1/L2 caches, high power/heat/CPU stress).

2 = Small FFTs (tests L1/L2/L3 caches, maximum power/heat/CPU stress).

3 = Large FFTs (stresses memory controller and RAM).

4 = Blend (tests all of the above).
