Steven is this exactly what you have please?....John

 

 

 

Intel Core i7-2700K Sandy Bridge 3.5GHz (3.9GHz Turbo) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623i72700K

 

Yes it is.

Great, Thanks Steven I just bought one. I am going to build a new system and I am buying the parts one at a time. Will take 3 months maybe. My current system is no slouch but I can see where there is quite a bit of room for improvement.

 

Thanks again Steven.....John

My temps are lower @ 4.9GHz on Ivy Granted I had to go through a lot of work to get it there, but it was worth it!

 

At 4.9GHz my temps are below 60c with fsx(about 56c), i still belive that sandy bridge is the best overclocker ever.

From 4.4 to 4.9GHz it was necessary to increase only small amount of vcore, big difference was only between 4.9 and 5GHz(from 1.40 to 1.48). And i didn't try to adjust any other value, maybe i can reduce vcore with some PLL, VCCIO, VCCSA tweaking, i didn't have enough time to try that

.

As for 5GHz stability on air with Ivy, it can be done and I'm sure has been. I can't do it with mine because the chip is too hungry for voltage, but my particular sample of Ivy isn't very good as I need 1.5V for 4.9GHz. A chip that only needs 1.4V for 5GHz could definitely be done on air. But that's beside the point, as a 5GHz Ivy Bridge is measurably faster than a 5GHz Sandy Bridge. Ivy only needs about 4.7GHz to match a 5GHz Sandy.

I'm pretty sure that everything can be done, but it would require a lot of work. I reached 4.9GHz without effort.

And i know that in theory ivy is a litle bit more efficient than sandy at the same clock, but i'd like to see how that reflects in fsx, becouse that can be only marketing by intel.

Did anyone tried to compare sandy vs ivy fsx performance at the same clock? FsMark etc?

I'm not saying that's not true, but 4.7GHz to match a 5GHz Sandy Sounds like a little exaggeration to me. (by intel, nothing to do with you TechguyMaxC)

I don't mean to try to take anything away from Sandy Bridge, it really is a fantastic overclocker, and your results are in line with what was by all accounts "easily achievable" by most. Ivy definitely takes more work to get to the same place. I haven't actually measured my FSX temps, I'm going to see about re-benching today now that I've got my rig all dialed in finally (5 months after I started this insane project).

There is indeed a difference, about 7% on average according to the FSX Mark 11 results that have been collected thus far, though my own results are a bit of an outlier, I'm going to go back and re-test (again) after having reloaded everything to make sense of the numbers. So with a 7% difference on average we can say that a 4.7GHz Ivy Bridge behaves approximately like a 5.0GHz Sandy Bridge.

Like I said, the 2700K is outstanding.

 

I suppose it really is the luck of the draw with any cpu, but it appears Intel's internal binning specifications between the 2600K and the 2700K has resulted in a significant difference in the average extreme performance envelope of the two.

 

It must be said that this observation is based on limited examples, so that likely won't be the case every single time. Unless quality control has attained near perfection, there will always be exceptions.

 

Kind regards,

The 2700k is great one, as you know à have à god 2700k and à nice 3770k with good mem controller,

I think its more easy to OC the 2700k. 3770 ned fast mems to outperform the 2700k

As Max pointed out the diff is little more if you have fast mems .

Today à run with phase change cooling the 3770 runs @5.4ghz 24/7.

Have done some fsmark 11 tests without any harder mods it hold an avg of +57fps

With this cooling thats not normal à decided to not publish fsmark11 results

 

Kind Regards Hasse

 

Thanks for the info, I am very sure that I will have more question as I gather the parts to build my next system. I am referring to the Mother Board, Ram I would like if possible to continue using ATI Radeon Graphics Cards too. ...John
