I stress my CPU very hard and when I'm prime95 stable, I get zero crashes. On a system that is less stable but not pushed hard enough to crash, you will slowly corrupt your data. You will then eventually end up having all kinds of errors that adjusting your overclock will not fix. Making corrupted backups of your corrupted data is of no help.
Tests like memtest are pointless and do no good once you know what your memory is capable of. It also doesn't stress your CPU which is when it will fail you. You state your opinions all over as though they are fact. Just because you don't use your PC a certain way or don't see the reasoning behind what others choose to do doesn't make it invalid. You choose to run at an easy overclock that requires very little testing as these CPU's do 4GHz without blinking. Those of us who actually push their systems have a higher likelihood of running into problems.
All I`m saying is there is no need to get into this.
I`m overclocking more than 15 years and I know that even if you Prime test a cpu/mobo/mem running at its max then one time or another it will crash. I guarantee this.
There are many reasons for this.
Ambient temp rise.
Power stage of motherboard.
Overheated memory modules.
and so many other
For me Prime or other stress tests are not a tool.
They are good only to stress the system making things worse. Like degradation, especially if you have tested with high Vcore.
I don`t use any such "test"
Once a cpu/mobo/mem can hit 470FSB effortless and at 450FSB seems stable then at 440FSB it is stable as rock. No matter if ambient temp rise, etc
But the same cpu/mobo/mem if it is left running at 465FSB Prime tested then one time or another believe me it will fail. No room left.
Vcore will be high stressing things more, like overheating and stress power stage.
Chipset and memory one time or another will fail stability. It does not have to be the cpu.
What I said is one coming from a weak E8400 @3600 to a E5450 @4000 or even 3960Mhz then the difference is huge. No need to push things like crazy.
If you personally want the max and going for the max then it is your preference, but not the right thing you may think.
Instability does not come out of cpu only. Motherboard too. And most times it is the memory.
Even if you think you know what your memory was capable of then you still have to test with memtest86+ for at least 10 cycles (10 should be considered the lowest).
This is cause that most probably you have changed FSB STRAP on motherboard by changing cpu and go from 380FSB to 450 FSB.
Different FSB STRAP = different memory stability.
Of course there are many other factors, like Turbo memory and some more other memory bios settings.
Then by lowering the theoretical stable 450FSB to 440FSB you have left room to:
other factors like those said above
Why would anyone need such a backup scheme? Only if he has important files. Like personal videos that want to keep them for ever.
One PSU failure and there you go. HDD gone bad, all files lost.
One click and gone. That click may come from another user, like your kid for example, or even accidentally from you.
In a few words as I don`t play games but rather use my PCs for doing a job then I stand no instability at all.
So for me more important is to leave some room than hit the max.
