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!
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.
Nah man ~6% IPC
Consumption is about ~19-20% lower
Surface area is about 25% smaller
But wait on me buddy, posting an article on this soon, just been too busy last 40 hrs or so
From the ES testing I've seen, 4.2 GHz to 4.8 GHz 24/7, low to mid 5 GHz range on dry ice and high 5 GHz range or higher on LN2. Retail chips may perform better or worse, we don't know yet.
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.
based on this test the Ivy runs hotter and clocks less than the 2600K
The extra IPC is offset by a lower OCing.

the Ivy is clearly more power eff. buttttt hummmmm
The Intel roadmap shows 2013. Apparently, there's already a working Haswell engineering sample: http://news.cnet.com/8301-13924_3-20...ok-revolution/
I don't care about the mobile/ultrabook information in this article, but, to know that there's already working Haswell silicon pretty much lets us know that this thing is definitely in the works!
Yep second generation will be the one to watch for, but I'm not going to count the days go another year..... Stuff that
When is Ivy-E due?
:(
If Ivy Bridge is really going to have only about 10% IPC increase compared to Sandy Bridge, then maybe Piledriver will be able to become competitive in the performance field and not just in the price field.
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.
