Ahhh, I was wondering why the ES were so much better than production. As you say, this looks like a fix for an issue encountered with IGP.
Seems two likely outcomes: either it's a temporary fix in order to meet the release date that will be fixed fully in later steppings with a consequent jump in o/c performance, or it'll have stay and the we'll only see smaller incremental improvements in the steppings.

Just watched this sorry if u've seen it already on Mb.org , http://www.youtube.com/watch?v=wSLA...DvjVQa1PpcFODJvuPgtdbxOazcF5B19KmHkO8OBDkwSs=
My new pc if i ever get a cpu ..............just a few more days.

wheres the "lets show how good these CPUs are at overclocking" thread we normally get from Gibbo pre-release ? we've had it on previous launches pre-release, Nvidia GPUs, ATI GPUs, and I seem to remember the 2700k etc.
bad sign IMO ? I mean NDA is up for performance

Gibbo probably wanted to overclock it.
All excited.
Hooked it all up.
Then thought, "hang on, this is the same as SB - its a waste of money upgrading to IB".
At the end of the day he is a salesman and his job is to create a buzz. But if the product is poor or offers nothing new over something which current exists, even a good salesman will struggle to create a buzz.

Gibbo gave us his verdict - it seemed to me - in the poll he started recently about who was going to buy it. Unless he was merely referring to leaked previews.

Sandybridge v Ivybridge overclocked 4.6GHz temperature and power:
It appear that sandybridge and ivybridge are the same temp but less power on ivy.

I believe that motherboards.org pic is at STOCK
if you notice - in the pre-bit it states the config and says the 3770k at stock and overclocked, the performance graphs show performance at stock and at 4.6 - the power/temp have no title - so I'm guessing at stock - otherwise it'd say overclocked
same temp at stock for 2600k and 3770k sounds right to me

He that runs the site motherboards.org and the same youtube channel is completely useless at benching, some of his results across CPU's and GPU's are embarrassingly inaccurate.
madshrimps have good bit on temps

Blimey 6.3GHz at 1.9v !!! Madness !!!

Apparently perfectly doable - for those of us with a supply if liquid nitrogen!

It seems that Intel is using TIM now under the heatspreader:

Before they used solder and in the article they suggest this is the reason it runs hot.

That's interesting. If they are correct then it seems an odd choice by intel.
However, I still feel for the vast majority of users the overheating might just serve to stop people overvolting and killing CPUS. I think most people buying IVY would be happy with a low voltage 4.5ghz. Certainly for someone like myself I should see a huge leap in performance.

As for the high voltages & heat issue, I am guessing that TIM heat conductivity may be efficient upto a certain voltage applied presumably low/mid voltage. At this point heat can be conducted away from CPU die in a seamless manner. So temperature increase is relatively modest.
However as cpu/core voltage is increased further beyond this point, you end up with far more heat accumulating at cpu die than that can be transferred by TIM. So temperatures just sky rocket at higher voltages.
Still it would seem that soldering of cpu die to IHS is more effective as it has higher heat conductivity as suggested by article. So this allows for higher voltages to be applied.
I am sure there is bound to be research somewhere that links voltage applied to heatsource area coupled with heat transfer/conductivity mechanisms.

Question is what is the max limit of temperature on IvyBridge for 24/7 in use ? Was 80C ok ?
Soldato
Good question. If so (like nehalem) then I'm good with that.
