Info Best utilities for stress testing in 2020

[Regeneration]

New threads related to unstable overclocks and defective hardware pop up on a regular occasion. It is often asked how to stress test some component. Below you'll find my top picks after weeks of testing - updated for 2020.

GPU
Unigine Heaven
FurMark / MSI Kombuster
*GPUs tend to clock down due to power and thermal limits when running FurMark*
*Lower resolutions put more stress on the VRMs*

Video RAM
Final Fantasy XV Benchmark
*Set to maximum quality and run in a loop*

Memory modules (configuration, timings and overclock)
MemTest64
HCI MemTest (one instance per thread)
*Best run from safe mode without a pagefile*
Linpack Xtreme

Memory modules (physical integrity)
MemTest86

Processor
Linpack Xtreme
Prime95 small FFTs

Integrated Memory Controller
Prime95 custom run of FFTs from 512K to 1024K with 90% of RAM
Linpack Xtreme

Northbridge, bus and PSU
Prime95 custom run of FFTs from 512K to 1024K with 80% of RAM + LuxMark or FurMark running in the background at 720p.

Heaven, but not Superposition?

You forgot real world uses. Oops! Almost forgot beta testing Windows 10.

I find that neither taxes my Radeon VII much. Heaven is pretty old and is excused but If I could take a guess I would suspect Superposition doesn't really push the compute pipeline much. Temps are quite low for a bench.

Superposition 4k Optimized does okay. GFXBench makes my Radeon VII crash harder than anything, interestingly enough.

High stable frame rate is more stressful than slightly better graphics.

- Why Heaven and not Valley then? I've been using Valley recently due to it still being DX11 but with more object density.

Valley is OK too, but 100MB bigger in download with less use of tessellation. It does have more object density but insufficient to stress the VRAM (2-3GB at 4K)

Superposition uses a lot of VRAM but the buffer is left untouched. Useless for a stress test. The buffer needs to be refreshed (load/unload textures) after some time.

FurMark and Heaven are better at stressing the GPU and Final Fantasy XV Benchmark for VRAM stress test.
