So the old P95 is actually a better stress test?

How do you define better ?

My understanding is this, using the settings 128 128 FFT's in place obviously stresses the CPU more than in newer versions, thermals are higher, power usage is higher.

So in this scenario you could say that older versions are a 'better' stress test.

But my question is, in what real world scenario would such settings actually be used by software ?

I dont know the answer to this question but I would not think it is a usual scenario.

When I use prime95 to test my CPU I use custom and 14000mb of my RAM this scenario, different lengths of FFT's are used while cycling/loading through all my RAM, in my mind this seems to be a more usual scenario.

Unless somone sits down and does compares with different FFT lengths between different versions of prime95, we wont really know the whole picture.

As of now it seems that 128 128 FFT's does indeed stress the CPU 'better' than in newer versions though with different FFT lengths this may well change.

Thats the depth of my knowledge on this subject so far

That's my definition of better.
I hear your argument about some loads being unrealistic, but that's the whole point of stress-tests: determine system stability under maximal load possible so that you can be sure the system is reliable in any real-world applications. Just my opinion.

Understood,

though again 'any real-world application'

If no real world application exists that stresses the CPU in this way then this makes no sense

Now if you said in 'any' scenario i.e. must be able to meet the demands of exisiting and non-exisitng software than I would whole heartedly agree with you.

I used to think that way also until new games came out that were pushing my FX to 80-90% loads and new encoding software came out that pushed it to 95-100% loads. I was persuaded to chase that unicorn and it payed off in a reliable system years later.

Don't think for a second that some of us aren't already pushing our rigs into stress test territory already. If it's going to crash it is best that it does it while stress testing and not under a real work load.

Failing in real world loads is bad news. It's how you get data corruption.

I'll just leave this here on the topic of stability http://www.overclock.net/t/990229/stress-testing-warning/20#post_13127125



This entire post (more than what's above) is still one of the best explanations of why we (should) test.
It's worth the time to read.
