The earlier result from Ivy does not come close to the i7-3930, so I am re-evaluating my options.

 

Yea the Ivy bridge doesn't look as good as we all had hoped... http://www.tomshardw...3770k,3181.html

 

There may yet be hope for IB overclockers: http://www.overclockers.com/ivy-bridge-temperatures

 

I cannot believe they even bothered with trying to improve the on-board graphics, but I guess that is the way of the future smaller and handheld. I am guessing in a year or two that they will start developing the high end Ivy's just like they did with the Sandy's.

 

Single-threaded CPU performance is getting harder to come by nowadays, and Intel is severely lagging behind AMD on the integrated graphics front so they need(ed) to invest in this area to secure more OEM sales.

No there isn't. HS removal has been already performed by several IB owners in forums without any better results. They got of course marginally better temperatures, degree or so, but there is really not anything wrong with the core/HS contact and thus heat removal performance isn't affected as many already suspected when the news came. All Ivy Bridge "problems" are due the new architecture, which means high current leakage when the temperatures inevitably rise and difficult heat removal due the small core surface area.

 

And yes, integrated graphics are important part of new processors. We have to rememeber, that desktop processors, which are sold mainly for gaming and desktop computers with addon graphics are just small part of the market. Businesses don't need high 3D capability for many applications and also laptop processor markets are the one that make huge profits. After all, better laptop processors are based on directly to their desktop processor brothers with some capabilities removed and new microcode. Also, with new popular Ultrabook laptops and so on, external GPU-chip on notebook's MB is not a good solution, as they tend to take more space, complicate cooling and draw more power. All in all, future will be in integrated graphics as it is simply put better option for many cases and external graphics is used there, where it is truly needed for some reason.

I'd like to see some links. I've seen one so far, and the person that performed the test did it wrong, as I explained here: http://forum.avsim.net/topic/372250-more-on-the-hot-ivy-bridge/#entry2354477

 

High core temps with low temps on the heatsink itself means poor thermal transfer. The manufacturing process feature size, transistor type, and power density have no bearing on the matter.

It was pretty obvious from the start, but if you insist, here it is done "correctly":

Guy did it first without shim, afterwards with it. Result: No change.

 

Translation from the post: This is how I tested the processor and the end result was that it didn't change the temperatures [compared to without shim, my addition]. As said before, it's more because of processor's architecture and physical properties, than of poor thermal conductivity or problems related to that.

 

This is getting ridicilous, but by all means, everybody is free to purchase IB, remove HS and beat Intel and these guys, like korrrhonen, who is a professional overclocker. This lapping suggestion is by far the best "requirement" for decent IB overclocking. Lapping hasn't ever been a viable solution to improve major overclcocks, not even in P4 or Athlon64 times with their poorly manufactured HS by todays standards, but only for extreme overclockers looking for the last MHz for their system. And now suddenly, HS is so distorted, that it plays major factor in IB overclockability. Give me a break. I kicked top numbers for water cooling with Athlon64s in their days just using top of the line custom water cooling without any lapping whatsoever.

 

And yes, one problem with Ivy Bridge is their small core surface area, which means, that it is difficult to get heat efficiently to the heat sink or water block. And HS has nothing to do with this. Still, as I said, what is causing this ultimately high temperature load durig overclocking is high leakage current in the processor due the new transistor architecture.

Now, I've purchased. Rex, orbx Australia, my traffic x 5.4b

 

I do not know how to overclock my CPU, nor do I know how to edit the fsx cfg file.

Can you please help me to get the best results.

What do I need to change in the fsx cfg. Can someone please show me how to oc my CPU, do I need to do that ??

Thanks

Just curious to see if you still stand by your remarks today, after several people on this very forum have successfully de-lidded their IB, applied good TIM, and re-lidded their procs only to have the temps drop dramatically when overclocked. Doing this on my 3770K dropped temps as much as 15 degrees under the heaviest loads. Theory is always trumped by practice.

You should read Word Not Allowed's tweak guide at the top of this forum for guidance on how to tweak your FSX.cfg file. As for overclocking your CPU, generally speaking you can simply increase the CPU multiplier in the BIOS and restart the system, run a stress test, then restart and enter the BIOS again to increase the multiplier one more notch until the system is no longer stable. Then you can start increasing Vcore until it becomes stable and continue overclocking. Most 3930K chips should be able to achieve something like 4.8-5.0GHz with decent cooling and correct voltage. If you require further guidance you should try an overclocking oriented forum like XtremeSystems.org or one centered around Asus motherboards. Also, the manual will show you how to find the specific items I mentioned in your BIOS.

Hi

Agree with the Grunt. Not see any major benefit in

higher clocks whith modified IHS.

my 3770K is pure standard.

When a overclocked Intel Merom and Yonah and old amd the shims

was the way to go.

Did a lot OC with AMD FX57 member in 4GHZ club, 3.8 FX60.

 

Hsse

Hi here is a test.

1. Stanard

2. mod repaste

3. without IHS, Shim

 

I'm not terribly interested in the results someone else attained, when I have twice now attained dramatically lower temps on Ivy Bridge by removing the IHS and replacing the stock TIM. If someone else isn't getting better temps - they did it wrong. As for obtaining higher clocks, that's hit or miss to begin with.

The test was done by friends at TechSweden with members like Kinc (XS hall of fame)

Here a from XS (Vinas) a agree with him 100%.

I buy my first cpu from TW (Hicookie) back in 2005 and not the last one.

It's nothing to to with the TIM. Well, maybe a few C at best. Sadly, the increased heatload is due to the higher density of 22nm architecture and nothing more. Think of it this way: more performance than IB but waaaay more transistors (IB has 1.4 billion vs 995 million in SB) so ~40% increase is A LOT of heat. The result? Even though it's a smaller process there is much more heat. To think that TIM could the single factor for such a huge change is a little foolish IMHO.

　

Did you even bother to read this thread? People performed tests and in overclocked+overvolted conditions, there can be over 20C difference just due to TIM.I did read the thread, and I don't agree with the blanket statement that 20C is a typical difference, but it's ok to disagree. IMHO the higher transistor count (even though they're trigate) is the basis for the much higher temperatures.

 

Edit: I get the lapping, removing IHS, using better tim's all account to lower temperatures. That is fine. I think though that the increase is more to do with density and less to do with TIM (that's all).

I have removed the IHS and replaced the TIM on two Ivy Bridge CPUs personally, testing before and after temps. My own 3770K, and a friend's 3570K. I used a razor blade to loosen the IHS, removed the stock, dry, crusty, gooped on crappy TIM and replaced it with IC Diamond. I then placed the IHS back onto the CPU, and reinstalled the CPU into the motherboard. Then I reinstalled the cooler, turned the computer back on, and tested temps. Reduction of load temps when overclocked was between 10 and 15 degrees C.

 

That is a significant reduction in temps accomplished by doing nothing more than replacing TIM.

 

Nothing you can say invalidates that. You can hold a different opinion, but these are scientifically proven results, not theory.

I am going to need to see a peer reviewed paper before I call it scientific ;)

Disclaimer: I don't mind destroying a couple of 3770K in the process, lol.

 

1) What does IHS stand for?

2) What does TIM stand for?

3) How did you remove TIM? Also with the razor blade?

4) Where to get commercial IC Diamond?

5) Are there some youtubes or articles on the process, just in case you've seen some?

6) What cooling system do you use on the CPU?

 

I'd really like to duplicate your results and show them haters, lol (sorry,

just kidding :D ).

 

Thanks,

Dirk.

 

Seriously, if the above really works it makes very good sense for me to build a 3770K-based system and run it @4,9GHz on watercooling.

 

Cheers,

Dirk.

I've now performed the same procedure on another friend's Ivy Bridge with the same results (i.e. 10C drop in load temps). How many times would you say this needs to be done?

 

Not only have I dropped temps by 10C or more across 3 Ivy Bridge CPUs with this procedure, but I have gone back and re-done my own CPU with Coolaboratory Liquid Ultra thermal material and a true water cooler and the results were dramatic. 32C drop. You can see for yourself in the Ivy bridge results thread in this forum.
