how to test for stability with EIST/C1E enabled?

I was just thinking about this. How does one test for stability with EIST and/or C1E enabled? If you run Prime95, then it will ramp to the max voltage and multi and stay there.

But how do you test for stability at the lower voltage/multi? Run normal apps, and pray that they don't crash? Surely you can see the problem that I'm alluding to here.

when i had those enabled and it dropped my multi to 6x, i didn't notice any change in my vCore in CPU-Z (might be wrong.) but to be safe why dont u find out what you're stable vcore is, then bump it up 2 notches when enabling those power saving options

When p95 starts, speedstep raises your multiplier to the max you specified. As well, if you're manually setting the vcore to your chip (CPU Vcc), C1E does not function. Also, if you find a CPU Vcc that gives a stable setting (p95 stable for say 24h ), there really isn't a need to add a few notches.

vcore does drop with EIST enabled at idle.

I actually can't see the problem you're looking for. Drop your multi and voltage to the levels that they are when EIST is enabled and test for stability then with EIST off? There hasn't been any need for praying with my system with the EIST/C1E turned on, and I wouldn't most certainly run this system with them off. Just the thought of running my system at 3.3Ghz and high voltage all the time makes my head hurt.
