And yes, it's possible to get 5GHz on air.

Good. Go write off everything based off an extremely small sample size.

Im sure its possible just very bloody unlikely, and as source statistics, that thread? Really? You'd take a highly polluted set over a smaller more qualitative set? Thats your provocative .. i just would be basing my phd on it you know..
"L310B487 (5,1 GHz 1M at 1,284 4C/8) good"
- That means 1M and beyond fails? Or?
I do not get the vibe that we're talking 24/7 stable overclocking here ... I could be wrong ?
What is it with you guys moving goalposts every time something doesn't live up to the hype? Suddenly, DC isn't targeted at the mainstream market and wasn't advertised as the return to SB-era overclocking? You people are the reason we have stuff like this, or the Titan Z, or the Hawaii reference cooler. Apologists are the ones holding the industry back. These companies get away with this crap because there's always someone with some BS reason to defend them.
That's enough, Techhog. Thread crapping will not be tolerated

Well that's my point. It's not "impossible," and neither is it impossible with all the cores enabled.
It's definitely well outside of what should be expected though -- I wasn't arguing otherwise.
I know it's not the clearest data set, but it demonstrates that there's a wide spectrum of max operation frequencies. You can't rule out the possibility of "5GHz on air" because of two samples. You can get a dud, that isn't stable even at its stock 4.4 GHz (very unlikely, but DOAs are always possible), and you can (probably) get a golden chip that hits 5.0 GHz on are. You can probably conclude that it's very unlikely, or rare to see 5GHz on air, but at this point it's looking like such a feat would be far more common with DC.
Maybe 1% of users will achieve that, compared to something like .01% before.

L310B488 (5,2 GHz Cinebench 1,249 V @ -40°C) good
That is not air
L310B488 (5g 1.35 32m 85 degrees 6510 1.8 CB -134 CBB -132 very very hot chip wprime 4.3 1.25 95 degrees) good
4.3GHz at 1.25v 95c but 5GHz at 1.35v 85c : That is not AIR
Most (if not all of them) of those 5GHz are not on air.
Not only that but nobody here will use more than 1.25v on AIR for 24/7 usage. They may be some dies that can OC to 5GHz but only for a suicide run, not for 24/7 like many SBs could.
Great, whatever. It doesn't matter.
Do you think 5GHz on air, with all four cores enabled, is theoretically possible for Devil's Canyon to reach, or not? I think it is, and I don't think it's that crazy to believe so.
If it is possible, then Techhog's statement is null and void.

See, Intel's genius plan is now unveiled. They generate an air of confusion around Devil Canyon by sending out press samples of varying qualities. This causes such furious internet argument that all participants are forced to purchase a representative sample of 4790k (say, 50 each) so that they can actually figure out WTF is going on.

Given normal distribution and another 200-300mhz headroom (as we've seen with the delidding folks), that doesnt sound unreasonable to me.
Despite all the overclocking fanfare, the biggest win here is with the stock clocks. It's funny to me that Intel managed to create a bigger performance delta between Haswell and Devils Canyon than they did when they released Haswell in the first place.
Packaging is one of those rarely appreciated, yet very critical pieces of performance.

Are we talking of suicide run or 24/7 ??
Im estimating that 4.7-4.8Ghz will be feasible with WC or with the Highest-End AIR coolers for 24/7,
5GHz will need way more voltage and it will not be safe for 24/7 usage with AIR(unless you have very low ambient temps).
For suicide runs just for Benchmarking we may see more than 5GHz even with AIR.
I don't know; I was just contradicting Techhog.
Don't mention my name. I'm done here.
Way to link the most BS stastic ever.
I have been watching that thread since December.
Those 5Ghz on air is being able to run long enough to take a CPU-Z screen shot.
Big deal, my 4770K also boots up at 5Ghz & I can take 100 screenssots for you. While mine is on an H100i, I could boot & take a screenshot on any halfway decent air cooler.
Benchable means it can run SuperPi & Intel XTU which are hardly stressful.
5Ghz on air isn't gonna happen even if Jesus blessed your chip.
Stop dreaming.

which implies that you dont know what you're contradicting? Thin ice here mate.
What BS reason do I have to defend them in my post? They lead in IPC right? They are only competing against themselves with this CPU because AMD can't offer anything that's comparable.
You quote me then you say don't mention my name when someone quotes you, not sure if you should stick around here because everyone gets quoted. Its a discussion on a forum no need to take it the wrong way because people get quoted to address something a user was talking about.
Poor word choice. What I should have said was that either works.
Way to be late to the party.
Not everybody is free at home waiting to comment.
I was approximately 2:30 late to your party.
If you have confidence in what you said, you can defend it even after 2 weeks.

We are starting testing of it today!
Thanks BFG
I don't, hence my response. Your post was unnecessary -- AtenRa already set me straight on the matter. Had he not, your post would have utterly failed in doing so.

Of course it would have failed.
Looking at your post I qouted, I didn't have much faith.
The same goes for you: personal attacks and thread crapping will not be tolerated. Both of you should have stopped before it even reached this point

Just a heads up: anecdotes aren't really convincing, especially in a technical forum.
I'm no stranger to being proven wrong, and am more than capable of accepting it. But if you think you're going to prove anyone wrong by telling a story, while simultaneously being hostile for no reason whatsoever, you're going to have a hard life.

I am not sure if I understand this post of yours.
I will try to answer according to what I have understood, PLEASE correct me if I am wrong.
Are you trying to say that my first post would have been not considered factual because I didn't have anything concrete to prove my point accept my personal experience?
If yes, then let me say this I don't think anyone in the thread you linked to, has claimed can run 5Ghz for regular use. So i think that my point that 5Ghz on air isn't possible would still be correct.
I think I know one person who can run 5Ghz on Haswell for daily use & he uses a Phase Change unit, far from air.
Pretty much.
And I have a friend who has a 5GHz Haswell 24/7. See how useless this is?
Your likeliness to accept an anecdote as true or false is relies on what you hold to be true. Seeing that you don't think 5GHz 24/7 HSW on air is possible, you'll undoubtedly write off my claim as false.
Seeing as I believe that there's a nonzero chance of the original Haswell series being able to be 24/7 stable at 5GHz on air... I'm going to be more than happy to dismiss your claim. Even if the chance is one in a million, or a trillion, or whatever... rarely is anything ever 100%. Considering you don't think it's possible even if "Jesus blessed it," I'm going to guess you're "100% sure" it could never happen.
Regardless, it doesn't matter. It can't really be proven either way, and it wasn't even the point I was trying to make, which is that you can't write something like this off with two points of data. I was hoping I could prove that it wasn't "impossible" to hit 5GHz on air at some reasonable level of stability by way of proving that even current Haswells can do that on rare occasion, but I wasn't successful in that endeavor. I'm still not convinced that it can't happen, but it doesn't matter at this point.
So, can Devil's canyon hit 5GHz on air? I still maintain that it's too early to say.
