Today Francois Piednoel is posting some interesting information and tips regarding overclocking over on his Twitter account:
FPiednoel
A lot of air cooling stuff so far but seems that he is going pretty in depth and will discuss some sub-zero topics.
meh. nothing new that you cant learn in high school physics.
That's what I said. The remarks he makes with Dry Ice and "air cooling" are reference to some shouting that was going on over the Computex "air" numbers that hit the media.
Hadn't paid much attention to media Computex coverage outside of Facebook posts so I'm in the dark about what you're talking about. Any links or enlighten me? Anything he's saying have any validity?Quote:

As far as what Francois is saying? I think even a 12 year old could guess that higher water vapor content in the air would lead to better thermal characteristics, for example. Air isn't a very good medium to transfer heat.
He goes on talking about power consumption vs temperature and etc. all of which he says is true too.
Just FYI, these were the XTU results of the Amateur overclocking competition. They just used a Cooler Master AIO with no tweaking the ambient.

yea at computex a cold box with LN2 was common, we made the mistake of using a closed loop watercooler instead of an air cooler, but yea... i felt the same thing when i read his posts. I heard Intel was a bit surprised about the air cooling results at their comp, until they realized it wasn't really air cooling in the common sense of the term.
We used air cooling only no ln2 on our system. Was proud of that. 5496mhz Cpuz on air using slow mode and power tweaks
HAHAH I forgot about that :)Quote:

Massman: of course, 4800 MHz with allinone in XTU is nice, but most of Devils hit around around 4700 MHz stable. Is the same, I can do validation without change the ambinets with my FX over 5700 MHz and OK voltage or 5300+ Cineebchs run. But stable? Not, max stable around 5 GHz. Maybe some very good delided 4790K could get 5 GHz XTU benchmark at air/allinone with safe voltage, but not average Im sure :)
So all we are seeing is binned ES chips and what they can do ???
Been there before, then retail hits and everyone says.. hey what happened to 5ghz ??? we have to bin retail to get that.
but the new thermal interface material tastes like terrible cheese! that has to be worth something right? (did i just violate NDA?)Quote:

I tagged you asking about this on facebook in the midst of arguing with others on the topic and you didn't answer :p:Quote:

This thread is too much! You guys are hilarious. :rofl: I'm surprised Movieman hasn't chimed in with his 2,000,000 cents worth.:D
Movieman who ??? does he even login here anymore ??? ;)Quote:

Well , only 3 more days to go for the guys into Devil's Canyon retails :D , It would be unfair to compare hundreds and hundreds of ES Devils canyon highly bin cpus at computex with retails.

The HT off results have an even bigger gap than with 4770k. so i have a feeling the thermal paste is worse on cold lol.Quote:

Even guys on Single Stage Phase Change cannot boot Devil's canyon at 5.0Ghz into windows at -45C :eek: , eerrhh tha's how bad it is :/ as per Ramsus with his new retail 4790K in a tread at hwbot : "" Just got my 4790K retail today. So far i'm not impressed. I cant even boot my 4770K 5 GHz profile on single stage. ""

So expect around 5.6Ghz ~ 5.8Ghz Mhz on Ln2 guys , and 4.6Ghz ~ 4.8Ghz Max on water , terrible :shakes:.
And this is why I will bin a f(l)uck load of G3258's at least if they are complete garbage they are only a $60-$70 loss instead of $300.
some guys froM DE have retails. One said 4.5 GHz PRIME stable and second one 4.7 GHz PRIME stable. Think, 4.7 full stable seems good for daily users, better than average retails of 4770K
Yeah Chispy that is sad :(
Was hoping that we could get at least 5ghz on good water cooling, not the AIO's units. But that doesn't should like the case.
So much hype on these... YEAH we are back to Sandy Bridge 5.0ghz easy. Doesn't sound that way :(
I think, one part of this could be 22nm 3D process. Its real, with new Skylake we will be happy for 4.5 GHz OC
DC is merely the same core as older Haswell chips in a marginally better package. To expect it to revolutionize the overclocking potential of Haswell, is unreasonable.
So what do you think guys - next real bump in clocking will be BROADWELL K 14nm :D next summer:down:?
Or any other improvements rising on horizon?
:welcome:
seems you guys need more humidity to hit 5ghz.
Could probably use more cowbell as well...:p:
:D - that's the reason I'll keep my delidded IVY till the f.....g INTEL company will release BROADWELL K after all the delays:

I'm very confident 14nm will clock us into a new aera - nowadays all in all everything is gettin' bored time after time..............:cool:
