You could run 8hr 27.9 tonight, go to sleep, wake up, it's been 8 hours, take picture, and go straight to 5.2 if you want to wake up and OC. That way my testing in no way hinders your attempt at 5.2. If you cannot manage to do Prime due to temps, you can try to bypass that with a cooler test but running it for much longer periods of time. This obviously has drawbacks such as the time it takes. For example, 8 hours of x264 is already considered stable under any level of scrutiny IMO. So say you want 8hr Prime normally, you can just run 12hr x264, BF4 12hr. And bam, that's a dead on stable. Dead on, bullseye, let's go drink fruit punch stable.

I don't think any rig I've ever built is "...dead on, bullseye, let's go drink fruit punch stable". I mean, we're overclockers, right? I like living on the edge of twitchy. biggrin.gif

I'll set up to have a go at 8 hours of prime later when I get home from school.

So.....if I chart 5.2 with 10x passes of IBT can we chart that? Or does it have to be multi hours of Prime/x264 stable?

IAF, all it needs to be is stable for an 8 min bench for me. My quest is to get a few HWBot points before I move on to dice and LN2 .

No, I have not scientifically tested this idea, but that's what I think of intuitively. Or maybe we can say, Prime95 doesn't do 100% just close to 100% as mouse doesn't lag, we can stil watch Youtube?

If you set x264 to low priority, it doesn't lag mouse.

If you set x264 or prime to high priority they do lag mouse

What you're seeing is 90% down to just default priorities set. I manually set prime to high priority (as do many others) while testing, but that kinda disables the system

Specs of the settings in question are here:


For clarity delidded temps and settings are ALWAYS specifically noted otherwise people will get the wrong info.

Ok, so.

Now is time we bring up the painful subject of the charting and the way we go about getting the data.

I've yet to go back and iron out the small details I have not corrected in the chart itself, neither have I PM'ed people from the chart yet to harass them for followup info. Both of which will happen later. I managed to get the submissions charted from the past two weeks an hour ago all charted.

Should we have some sort of standard for the chart? I mean, some standard that must be met to be charted at all. Or to be placed in the official list. If we're going to have requirements like this it makes less sense to allow submissions to skid by without picture verification. It also means I'd have to ask every person I want to chart from random people in the other two Haswell threads to cough up stress test runs out of the blue which will impact the submissions I receive in the future because there are still THREE Haswell threads and the mods didn't decide to do anything.

And if yes, we need a standard, what should it be? I'm thinking, either x264 x500 pass or Prime 5hr. But that's is pretty damned stiff if we're asking EVERYBODY on there to do the test. Asking EVERYBODY to do ANYTHING is going to be impossible to begin with. Then I'd have to dock off tons of entries. Should we maybe have a third alternative? Like IBT Very High x20. Uhm... XTU 15hr? Are my suggestions too difficult, too easy? Just right? Or what? Tell me what you think about this whole thing and the credibility of the chart. I spend a lot of time on the chart and the guide and if either one of them is discredited for any reason, that is a big problem.

The solution is 2 charts. Keep the one you have (it's very, very useful), and then have another chart with a pre-defined menu of tests and prerequisites that must be passed to get on that chart. People who get onto the second chart get a gold star or something. specool.gif

Just keep both charts updated, because I can't see a whole lot of people downloading a bunch of programs, trying to figure out how to use them, running them for hours on end, and taking screenshots with various other programs open. Some people will depending on the battery of tests but the second chart will be way smaller than the first, and therefore less statistically significant.

That's not CPU related so it's not degradation caused. 101, 124, 9c are the ones.
You have been charted.

Philly, for such a high multipler do you mind doing more extensive tests with prime? People will be looking your OC under a high magnification microscope and they'll probably diss your entry and my chart. That's the reality, so if you have the time and you're willing, can you post pictures of several hours of prime? To minimize productivity loss you can just set it while sleeping, wake up and take a screenshot.

Check the stress test temperature chart. I'm using Noctua D14, so little worse compared to yours but mine is 4670k so add say... 5-10C to my temps to my Prime 27.9 temps. Thanks for the compliment.


DigitALL power, vdroop compensation 100% setting.
Charted, don't recall seeing the picture.

You mind filling out the form on the first page?

Updated

How is it going now? Warning: Spoiler! (Click to show)


Mind filling out the form on the first page?
Just stick with 4.5. Comon, the median and average OC is listed on the OC chart. You're fine.

I want to know.

You mind trying a harder test? Like Aida 5hr, x264 overnight, etc. Helps up the credibility of my chart. Would appreciate it if you do.




Charted

Kk, charting...


Charted
Charted, what test is that?

There's not much way to tell. Can't be cache because it's at stock. Either vcore or input voltage, right.


---

I haven't done any more stress testing. I've just been gaming (BF4). Once I raised VID to 1.280 I haven't gotten another BSOD in days. I'm not ready to be charted yet because I want to tweak it more. See of there's some way to get VID lower. My current OC is this:

45x core
1.280v VID (1.312v Vcore under load)
42x uncore
1.15v Cache voltage (1.208v under load)
1.78v VRIN (1.840v under load) (LLC on Auto)

VRIN is set to .5v above VID.

For me that has almost always been vcore. YMMV of course.

@coelacanth

Those are the exact same settings I am running at the moment!

I'd love to see any of the changes you make as you continue tweaking.

Long lost, Haswell brethren?

I just find it hard to believe that I can't get stable with 1.35 @ 4.4. If I try lower, I can barely get to the desktop. Not saying you're wrong at all, in fact you confirmed what I thought all along despite what I found doing a search. I just think I'm missing something obvious.

What's the stock VID on your chip?

I know going by stock VID isn't 100% but in my very small sample size it has been a very good indicator.

the first 4670k I bought (costa rica 331)would only boot at 4.4 @ 1.36volts.

It wont go any higher no mater what voltage. I tried 1.47volts and it wont even make it to windows at 4.5. Its in my 2nd rig now. It serves my son great at 4.3ghz for gaming.

Just not much of a high clocker.

Tbh the difference in his 4.3 and my 4.7 is not noticable in any game. It translates to about 3% per 100mhz core. I am basing that percentage off what the asus software tells me when i move up or down 100mhz. That 12% is much less apparent in games though.
