So what's the word on the street, 3770k going to be able to do 5.5GHz on ambient water? Last few "articles" I've read said the voltage has to be kept so low that 5GHz would be stretching it.

Stick with SB for 24/7
if you can keep load temps around 10C maybe 5C or 0C under load you should get ivy.
Just tell us what to expect for 24/7 on air/water, both frequency and voltage!
Well thats a disappointment, why wont a smaller process achieve better 24/7 clocks?Quote:

You guys can't buy them now, why can't you wait to see how retail CPUs OC? You can't compare results of E0 stepping ES to retail, especially b/c E0 is worse than ES E1 stepping CPUs for air/water.
If China and Russia have retail CPUs then what are they buying? Not retail stepping?
If the low voltage thing is correct then this will be a big disappointment to everyone that has been waiting for these, even more to the ones that skipped sandy to wait for Ivy .......
I wonder if Ivy-E will offer gains over Sandy-E or if they will be in the same boat .....
:down:
Well.... Ivy is around 10% more efficient than Sandy and uses around 10% less power doesn't it?
The world of OC is "Your mielage may vary." Intel have a viable product that is A/ better than their previous offerings and B/ introduces two major changes- 22nm and 3D transistors.
You're complaining about....what, exactly?
We listen at different streets if that is what you hear.Quote:

So all we stand to gain, if we arent on LN is the 6% IPC gain ?
So sad ....
:(
A few conclusions, before I'll submit everything... But, unfortunately it is less in your case, my initial figure was 0.912% boost, but, in that equation IGP-CPU ratio on DIE was equal on ivy and sandy, which is not the case..... You will hit lower performance with your watercooling on a K-model, with Ivy Bridge, compared to Sandy Bridge.Quote:

Maybe.
For real though, Piledriver better be competitive because AMD has nothing else until late 2013 or so, and Haswell will be released before that.
so Z77 + sandy = way to go ?
could spare me 3 weeks of waiting for my new toys :p
Ivy bridge K cpu should do at least 4.8Ghz <1.35Vcore with minimum 2400 mem on air...which most SB can scale easily but with less mem freq
Why is everybody surprised by the high temperature of ivy bridge? The die is much smaller than sandy bridge but power/area has increased and temperature dead end is still the same (90C-100C?). So you need a much better heatspreader to cool ivy bridge. I have seen the same on my Q6600@3.6GHz vs. i72600K@4.6GHz. Under full load both need around 170W. The Q6600 is arround 65C and the i7 is at 85C. A cooler has only a certain cooling power at a distinct power/area. When you compare power/area you see why the Q6600 is much cooler.
That seems highly unlikely consider bulldozer is not at all competitive with sandy bridge.Quote:

I'm putting my money where my mouth is by purchasing an i7 3770k on launch day. I believe it'll OC better than snb because of the data Intel shared on tri-gate transistors. Reducing leakage that substantially ought to increase thermal headroom, all else being equal.
Oooooh you don't really want to do that with everyone here :rofl: Unless the retail chips prove to be significantly better than ES samples.
If we are talking air and/or watercooling, I will take that bet.Quote:

what makes it clock so well under exotic cooling and supposely not under air or water ? the need for extreme vcpu ?
Probly because its 22nm process of the CPU die....internally the cores not being able to dissipate the heat quick enough with regular air cooling/h2o
What is max turbo multiplier "only" 63x? Why not 64 or 65x?
8 or 16 bit ?
I can totally see Intel putting some 'blank' die space between cores in the future, just to aid the dissipation..
Either that or making transistors work at higher temperatures.
or superconductorQuote:

damnit why no 3770K ? :'(
Smaller die area surface to enter in contact with the IHS and so on with the cooler.Quote:

More tranzistors/mm^ of die, more heat per mm^ but less contact to disipate so in conclusion bad thermic transfer.
Intel to help should make the IHS from a much better conductor material and may be to ensure a much better contact with the die.
May be an copper IHS should help. :up:
OBR posted a graph about air overclock: LINK
As so many other sources have hinted also, seems like Ivy has exactly same overclocking capabilities as Sandy. We're still looking at 4.5~4.8GHz 24/7 use range or so on air for most users based on all results seen so far. I personally expected more but I suppose tri-gate transistors which are new is probably the cause of the slight "downgrade" in OC capabilities, if the trend had continued as previously with a lower process node (I know I know, lower process node doesn't garantuee better OC capabities as there's so many factors that has to be taken into account but by going by the history it has), Ivy would have done aprox 5.0~5.3GHz as easily as Sandy reaches 4.5~4.8GHz so with that in mind it's a slight letdown for me.Quote:

I was really hoping for 5.5 to 6.0 GHZ with 20% bettter IPC than Sandy. Sounds like my hopes and dreams are about to be shattered. :-/
Lets hope they prove me wrong on April 23rd......
When you're hoping too high, you will always be disappointed :p:Quote:

"KEEP YOUR SANDY BRIDGE! E1 IVY BRIDGE ARE SIGNIFICANTLY WORSE OCERS ON AIR!"
A few people with hands-on experience have told me this, so I'm worried also, it's great for the LN boys but worse for the rest of us. I never wanted a 2011 CPU due to expense but I'm starting to look now because Ivy won't help my PBs...
:(
As I've said for the last month, mid 4 GHz range tops for most. Agreed with OBR, for 24/7 use HANG ON TO YOUR SANDIES!
if you get a Z77 mobo and a 2500-2700K cpu for it can you get the higher rams speeds or is that directly to the imc ??
Iam on water too.
CPU limited...
Glad I grabbed a couple more Sandy chips, Time will tell for sure but so far it seems just slightly faster.
You're still limited to 8x/8x pci-e 2.0 with sandy. GTX680 seems to like the extra bandwith.
The higher memory ratios are not available to Sandy Bridge.
That's too bad, gents. That's really too bad. Bring on Haswell and we'll all start again anew.
Probly with air overcl0ocking IB won't beat SB, but @ least theres a difference in memory overclocking 2133 and 2400+
Awesome Dumo are those my rams? Any idea how four sticks will clock? Have you tested Ivy under single stage?
:D
Meh. I'll take the tighter timings, most days of the week.
/Déjà vu
Scaling starts to drop away very rapidly past about 2,700 MHz anyway, but if you're shooting for records there's no doubt you want every last bit of scaling available.
I would too if it scored better but 3D11 seems to like mhz over latencies.Quote:

Keep on hoping for them clocks on on air... some expectations are just too far fetched... really 5.5 - 6ghz on air 24/7 ? that would blow the entire high end Intel lineup to pieces...
What about a new revision, no hope for that?
Stepping 9
Air/H2O:....4.9~5Ghz 1.35~1.37Vcore
SS -40C....5.5Ghz~ 1.55Vcore
LN2 will be the cooling needed for max Mhz
1.35~1.37v is getting a bit high for 24/7 usage on air especially for 22nm. I'm expecting most people to stop around 1.3v at launch not necessarily of temp (I bet tempwise 1.35v should be just fine on a good aftermarket cooler) but cuz of potential degradation which is hard to know what to expect from a new launched CPU hence ppl tend to be slightly more careful at launch with voltages. So I still expect people to stop around 4.5~4.8GHz for most samples, some people may be lucky and may get 4.9~5.0GHz out of a good chip at lowish voltage of 1.31~1.33v or so perhaps as there's always those lucky bastards out there too that I unfortunately do not belong to. :PQuote:

Does anyone know what the price on release will be? Not the advertised RRP, it will eventually settle to this but early adopters will pay much more , so how much do you think they will be?
:)
I expect $339 and $229 launch pricing of 3770K and 3570K, should be pretty close to 2700K and 2500K pricing and it to stick to that probably for a couple of months or so.
MicroCEnter just has a sale on 2600k, $199, there all sold out as of this morning!

Based from all the results i've seen from leaked samples, having high temps is 'that' consistent. :rolleyes: Surprises.
it's a challenge with 4/8 past a certain point - LN2 will be must have.Quote:

it's okay for air / water / ss I think...
A fellow in norway just got a 3570K and threw it in his Gigabyte GA-P67a-UD7 and he only got max 38 multi. So he ran out and bought a Asus RoG Maximus V Gene...
Ivy Bridge gets 95W TDP, worse overclocker than Sandy Bridge
http://www.nordichardware.com/images..._95W_front.png
earlier rumoured TDP was 77w: SourceQuote:
It is Intel's new 22 nanometer technology with Tri-gate transistors that has brought these limitations. The transistorsare extremely tightly packed and the die size is so small compared to earlier processors, that the heat cannot be removed fast enough with air and water cooling. Rumors has it Intel is not entirely on the mark with the new 22 nanometer technology and a box shot of a Core i7-3770k shows a higher TDP than earlier expected.
Worst overclocker layers...
"Mhz scale to 5Ghz" ability for IB probly so important for majority of SB owners, but a 3770K that can clock memory to DDR3 2900+ on air is the ones peep should looking for:D
Just my 2cents
Iam on the fence
Have a 920 system and iam going to upgrade for a couple reasons.
1. faster CPI
2. faster MHZ
3. SATA 3 for my 830 to run full speed
4. its time for a change :)
Looking at Ballistic DDR 1866 ram and GIGABYTE GA-Z77X-UD3H mobo and either a watercooled 2600K at 5 ghz or a 3770k at 4.7 ghz and at $199 at microcenter the 2600 is looking sweet.
BUT the Virtu MVP feature looks usefull can the 2600K use Virtu MVP ????
