I want to stress test my gpu and cpu, what free software to use

[code99]

Im debugging a system, im trying to figure out why its crashing and i want to see how stable it is by stressing the cpu and gpu but im not too familiar with the various software options out there.

 

What should i use for this task? It has to be free

OCCT for CPU.

 

Unigine Heaven for GPU.

Do you want to stress-test both at the same time?

 

I usually run Cinebench and Furmark simultaneously

not necessarily but ill give that one a shot as well. Ill try separate at first and if that wont crash the system ill try both

OCCT

Stability test, load test and it has built in monitoring. 

It actually has GPU load test  too, but no GUI for that.

Unrealistically, run Furmark + Prime95 SmallFFT  (Blend if you also want to test the RAM, but takes longer).

This is a highly unrealistic workload designed to push the hardware to its knees, basically. It will create a TON of heat, so check your temperatures and stop the tests if they are getting too high. Open your side panel if need be and have an external fan push air to it.

For me, this usually finds any issues within 30 to 60 minutes.

Simply running cinebench is not enough to determine if the CPU (OC) is truly stable or not.

If you want to see what's causing crashing, don't run them at the same time.

Like i said, ill run them on their own at first. If that doesnt give me a crash ill run both, who knows

for testing instability on the cpu side, i like to use Prime95 as a "worst case", and a "sanity check" with 7-Zip's benchmark. 7-Zip also does a fairly good job at finding memory errors, without having to run memtest overnight.

 

and for the gpu side, furmark is the "worst case", and the vareous flavours of unigine (valley / heaven / superposition) are a good 'realistic scenaio'.

Well, pc crashed AFTER furmark.

 

I will make a post in the Troubleshooting section of the forum.
