I have been noticing how insanely hard it is to run prime95 long-term with no crashes. It is practically impossible for me unless I increase the vcore into an uncomfortable range, and my temperatures rise above what I would want them to be at. However, it is so easy to get stable under things like 3dmark and gaming. My question is, what is the benefit of being stable under prime? I never crash in the OS, only when I run prime95, it's just insane, I have never run anything that has stressed all of my cores to 100% and caused my system to crash.
I have a phenom ii x4 965 BE and it seems impossible to get it any higher than like 3.85 ghz and remain stable under prime. I have tried higher frequencies, and I never crash in the os nor in games, but I get destroyed in prime. Do I really need to be concerned if I'm not stable in prime?
You do not specify what you mean by long term Prime95 run, also you don't specify any settings you're trying to use in your overclock, are you actually creating your own instability problems.
You have a 965 BE which is an unlocked multiplier CPU, you do not have to increase your base clock or FSB, or memory speed and timings to successfully overclock it, you do not have to balance out voltages of Vcore, PLL, VTT, GTL, and tune all those voltages back into a specification window to get a stable overclock.
You can successfully overclock it by simply raising the multiplier and discovering the CPU voltage required to run a higher multiplier and leaving everything else within it's specification window.
I've gotten so many PMs from people claiming they have followed my Black Edition Overclock Guide to the letter, then discovering they haven't, when I ask them to list their settings.
If you are truly overclocking simply by raising the multiplier/vcore and leaving everything else within specifications, long term Prime95 runs like 24hrs are not necessary, even though it will pass it, 2 hrs should be more than enough to show a problem.
I've seen Prime95 long term runs crash at about an hour into a game simply because Prime95 is CPU and memory stressing, when you throw the Graphics card 100% into the picture, you just added an element Prime95 did not test so this belief Prime95 is an infallible testing platform is total horse crap.
More and more today with the continuous releases of the AMD Black Edition and now the Sandy bridge K series unlocked CPUs overclocking is becoming so simple, too many today are still Old Schooling it, but times have changed and we're going to see these old practices fall by the wayside when people start to learn not to over complicate a simple overclock, and create your own instability.
We'll probably soon see better testing and stressing programs coming on the scene that include the full access to stressing the graphics cards too, but until then you can use bench marks to stress test, by using the instructions I placed in the Black Edition Overclock Guide!
