I don't know why you'd want to disable turbo anyway.

I wonder what the reason is for the default setting being never to downclock the uncore and leave it at 3.9GHz? headscratch.gif

Curious.. do you see the cache volts go down? Even in Adaptive mine stays where they are (but then, HWInfo reports it 0.04v [1.23v -> 1.27v] higher than what I set in BIOS).

If I did have one I would have no problem going back and forth with you thumb.gif
We all have opinions and interpretations of things, it's just some people are more tolerable of a debate/conversation. Others will rage if you don't go and prove how gravity works to them.

1 person stability tests for 1 hour & never crashes with anything he does on the PC after that test with the same settings. Another runs 1000 hours of tests & never crashes with anything he does on the PC after that either.
Both kinda fit that definition. Stability is a personal opinion, as long as it doesn't crash on you after determining for yourself that it is stable, does it matter what test(s) were used or amount of time it was tested?
Only in a club that has 'run this test for XXXX time at XXXX difficulty' to meet the requirements.

When we take it to that extreme it does work both ways.
When people mention prime, we never know what they are doing on prime for those 24hours.

My concern and personal worry is, I just did 45 passes on x264, so then I load prime and set a X-X FFT with X RAM and I instantly BSOD.
With knowing this, I have to ask myself which "real world" application is going to simulate this work on a cpu, and if I bsod then am I going to lose valuable work or time on whatever I was doing?


"real life example" I'd like opinions on.. Should I run 1.295 4.4GHz with 1.83vrin which passes overnight runs of x264 and other stress tests or 1.315 4.4GHZ 1.83vrin which handles all including prime with the maximum heat put on it. When I start OC'ing ram and then my uncore, how will I know it is the 1.295 or 1.315 aside from bsod codes?

If you get a BSOD, you pay attention to the error code, then make the necessary adjustments....

Yes, I have been doing so but not sure at what point I should stop.
I don't know if the specific FFT and prime version may be conflicting with the chip or it truly can't handle that workload when system is fully stressed.
Guess it will be safer for me to raise vcore than blindly start fiddling with the other settings.

You can imagine how frustrating OC can be biggrin.gif Letting tests run for hours/overnight to produce errors to spend the same amount of time to see if it is resolved just to move onto another setting.

On a side note, I am a bit surprised, I've been seeing the chip stay under 70C on all cores with many tests after dropping x45 to x44 ~1.3ish

By your dictionary definition of stable, you shouldn't stop until it never bsod's ever.

Prime95 is not conflicting with the chip. Your sistem can't handle the workload.

Some people don't care if their sistem doesen't handle Prime95 load, because you can hardly find a program in real life with such load. Its up to you to decide what is importatnt to you ...

Indeed, which is why I'm not messing with other settings. I can not afford to use this computer for work to have a random BSOD

But I did ask a "Would you rather:" to see how others felt and if maybe someone could provide a different approach to producing the bsod / testing the system.

As one of the mods mentioned, there is no way to produce 100% true stability, only what we can perceive.

Either way, none of this can give a black/white solution to whether the bsod prime is producing related to the work given to the cpu or a conflict from "updated" or "improper" versions to the haswell support frown.gif

Thanks tomlev5 tongue.gif I assumed this much, I was a bit worried considering prime has been updated a few times with "haswell support" and I did not know if this particular update was more efficient than the other one or just something buggy

I've never understood the whole "unsupported" thing with Prime95 and Haswell. Prime is doing the same calculations it has always done, why would it suddenly now be "incompatible" with a new CPU? Makes no sense.

I believe he is referring to older versions of prime that didn't support avx2.
