how should i stability test my cpu

[fc0712]

hey guys, i want know what program i should use stability test my cpu on and how long it should run in program?

i have a 3570k at stock first i want to test if the processor is stable at stock because i have had some problems with the pc in the past so i wanted to be sure it is not the cpu

and then i am thinking about using asus auto tune and then stability test

so what program should i use? and at what settings?

Prime95 is a good program for that.

PS - it has some different tests (which are explained there).

ok then i will just run prime 95 large fft in 2-3 hours,

Others shared this with me, so I'll pass it along to you; the auto overclock will use far more voltage than is necessary. I'm using the z68 pro gen 3 asus board and the auto overclock had me at a bclk of 103 with a x43 multiplier, using 1.3 volts under load. I'm almost done manually overclocking to bclk 100.0 x42 multiplier and know the minimum vcore is 1.215 v. I can say for certain that the extra x1 multiplier would not require an additional 0.085 v.

Kenmitch also suggested this to me for stability testing with prime95:

is it true what he say from 4.00 to 4:33 about damaging your cpu

It's actually a lot harder to damage Sandy and Ivy CPUs than previous generations. They have both current limiters and thermal throttling to prevent damage. It is possible to disable both, and you may find that you need to adjust your current limit when overclocking. (Don't disable thermal throttling!) But basically just watch the temperatures and shut it down if they get too high for your liking.

What's "too high" is a matter of debate. For Ivy I'd say >75C for an extended period is too high. But the technical limit is over 100C.

Finally, I don't believe what he says about whatever program being a better test if it doesn't heat up the CPU. High thermals at low voltages can lead to computation errors (but not CPU damage if the voltage, current, and thermals are within specs.) You need high thermals (relative to idle and to normal applications) to ferret those out, as even normal applications could generate high thermals occasionally. Intel Burn Test is another application I'd suggest running.

Linx

Go to Steam and buy Forged Alliance. Play a game with 8 cheating AI.

I have found Prime and Linx to be useless for Ivy.

Linx helped me with my overclock ... I couldn't even pass it once when I tried before ... and it really stresses the CPU alot.

Well I think that's a bit strange, like I said I have found Linx to be useless in my case. My cpu happily completes 20 runs with 8GB ram and AVX enabled while Prime95 causes errors after a few minutes (so Prime is not completely useless, it works ok for rough stability testing).

And yes it does stress the cpu a lot, higher temps and power usage than Prime. For my previous i5 750 it was my preferred stress program and I never had crashes or lockups if an oc could withstand 20 runs. But not with this 3570K.

So Prime works better than Linx for me, but still not good enough since even after overnight Prime sessions (and I tested this with different freq. and c-states both enabled and disabled) I have crashes while playing Forged Alliance, which are solved by adding 1 or 2 extra steps of vcore.
