I am building a new system to replace my first generation i7 860. I currently overclock to 3.6 but can only get frame rates around 33 with the 737NGX with my sliders in FSX set to 50%. I just purchased an Asus P8Z77-V Mobo and i72700K Sandy Bridge at Microcenter. I was initially going to buy a Z68 motherboard but all the Asus boards I was interested in had already been removed from inventory and I didn't want to take a chance on Asrock which is why I got the Z77 with a Sandy Bridge CPU. For $10 more I could have purchased an i7 3770K but overclocking and heat was my concern which is why I stayed away from Ivy Bridge. I still have a few components to buy but should have everything ready to build in another month or two.

 

Just curious if there are any Ivy Bridge overclockers in this forum and what kind of temps you are seeing with a mild overclock. I have never and don't plan on running a multiple GPU configuration. Any compelling reasons for me to return my 2700K and pick up a 3770K?

No, the 2700k is fine, 3770k isn't any better in terms of FPS.

Yes you should get the 3770K while you can. For folks who already have a 2700K system, it may not make sense to go IB...but if you starting out now, I can't understand why anyone would go with anything other than Z77 and 3770K or 3570K unless prices drastically drops on the SB.

 

You can get 4.5Ghz with 1.25v and no heat issue at that OC of IB. That should give you at least 4.8ghz of the SB equivalency.

 

Or better still, build it..over clock the SB to the limit that you are comfortable.. and go get the IB 3770K or the 3570K and do the same..and return the underperformer and let us know what actually happened.

 

so far, Z77 with IB OC to 4.5Ghz 1,25v (temp less than 75C at its full performance with FSX and with a cheap 35$ cooler...no heat issue..and solidly stable.. no BSOD, no reboot... no stutter...no nothin.

 

I'd like more people owning IB to speak up about this old wives tale of ove heating IB at less than 1.3 volt.

 

I understand the skepticism and what not in the beginning.. but now,, there is more solid evidence of realty of IB. Its time to stop spreading the initial panic and deal with reality today, Lots of people are spending their valuable money for this hobby... I think we owe them some truth.

What cooler do you use, and what temps do you see Prime'd at 4.5?

4.9 GHz and aiming higher on my 3770k using water cooling. The key with Ivy Bridge is to get the heat away from the core, transferred through the IHS. It's near impossible to do this using cooling that is at or above ambient air temperature, so the solution is to replace the thermal paste under the IHS. I'm seeing temps just over 80 C in Intel Burn Test now, much higher than what I experience in every day use. FSX shouldn't ever get out of the 60's with these settings, likely even just 50's.

i use the cooler master evo 212 $35. Prime 95 stays at or below 80 at 4.5Ghz and FSX is around 72C. voltage at 1.25 multi = 44 x 102 = 4.48Ghz

 

Its going beyond that....where the heat issue comes in and you need to deal with it.

 

If you are at Max's territory then yeah...you got do what he says..

Max its time to show that you pass 4.9 Intel Burn test , what you show is 3 rows at 4.7 or have

I missed someting.

After you say that à dont do stabilitey tests , I passed 4.8 in Burn Test ,do you really now what tests

I do you, havent avsked me.

Anyway ask before, i show à 4.9 when you do it

You also need a good board with the 3770K, here is one....

The question is why would you want an Ivy Bridge if they are $80-$100 more than SB and aren't any better?

Fortunately for me I live near a Microcenter and the 3770K is only $10 more than the 2700K. I still haven't really seen any advantage in going IB since even at a mild overclock my temps will be higher. I won't use the integrated video. The only possible advantage would be the memory controller so rather than the RAM run at a native 1300 Mhz on SB I could run at the rull 1600.

The thing is, its not. An i7-2770k costs almost as much as the 3770K. if you go down the series to like 2600K or 2500K, the same thing with the IB series...it goes down along with it. There is no price advantage of going to SB...

True. The only advantage is a higher overclock with less voltage means lower temps. I am not an extreme overclocker anyway. Have decided to go ahead and swap out the 2700K for a 3770K since I am using water cooling.

I haven't bothered to post pics progressively, I just posted a pic of my initial results at 4.7 and intend to show a pic of the final result but if you would like a pic at 4.9 I can do that. I'll either end up at 4.9 or 5.0 depending upon voltage necessary and final temps. I apologize if my words toward you were unfriendly, it is just a case of misunderstanding as I thought you were saying you hit 5.1 on an H100 but that you also did not stress test.

Yes, there is, since 2700k is the same as 2600k except that it needs a bit less voltage to OC. 2500k is also the same as the 2600k, except it has no HT, which makes no difference in games at all. That means 3770k is the same as 2700k, 2600k and 2500k for gaming.

Your initial argument was that Ivy Bridge is $80-$100 more expensive than an equivalent Sandy Bridge and performance is identical. Now that it has been established that the price difference is negligible ($10 perhaps) - what is your argument? All else being equal, why not go with the newer chip that unlocks higher memory and PCI-e speeds, two elements which measurably affect flight sim performance? Myself and several other users on this forum have done so, and are happy with the results. Do I wish I could hit well in excess of 5GHz at a reasonable voltage and temperature? You betcha! Would I downgrade my processor and have lesser memory and PCI-e performance to do so? No way.
