I just want to say thanks to jacob for the guide.. i have p55 sli e655 and i7 860 and i just OC using Jacob's configuration, but i cant boot my PC on that Settings is there any problem on my configuration? or i will just increase vcore to achieve the stability..guys please help me....thanks in advance..i only get 3.7 ghz stable and i want to push it to 4.2 ghz using Liquid cooling...
 
 
 

Unless your computer is set up in a sauna, your temps should not be that high while idling at 4.0 Ghz.  I would look at your CPU cooler and make sure that it is mounted correctly.  The Hyper 212+ plus is an awesome cooler, if it is set up correctly.  Sometimes they aren't the flattest coolers, or they have gaps between the heat pipes on the flat area that rests against your CPU heat shield.  
 
To help with this,  completely clean off the old TIM from both the CPU and the CPU cooler.  Don't reuse TIM.  Now you can apply a little bit of new TIM on the CPU cooler itself, and work it into the cracks.  Then scrape off the rest of the TIM with a razor blade or something really flat, so that it only leaves the tiny bit of TIM filling the cracks.  Put a small amount of TIM right on the center of the CPU heat shield (about the size of a small pea, or a little larger than a grain of rice).  Put the newly prepped CPU cooler straight down onto the TIM and let the pressure of the CPU cooler mount spread the TIM.  You should have better contact that way.  The bracket on a 212+ IS a little tricky,  so try to keep the CPU straight while you screw in each screw on the bracket.  Screw them in like you would when changing a tire..  Screw in one part of the way,  then screw in the one directly opposite of the first screw...  etc..  Until you have even tight pressure across the entire bracket.
 
With the screenshots you gave me,  I don't see anything crazy that would make your temps that high at idle..  But one thing is for sure,  if you are getting to 95C + on load,  do not load that processor until you figure out this heat issue.
 
What does your processor idle at on stock settings?   

Just for comparison, when I had a Hyper 212+ running my 870 at 4.0, I would hit around 80C, and I wasn't comfortable with that. High heat and and high voltage will degrade your processor, so it's all about how much risk you're willing to take.

I think something is off though, because I don't see how your temps are getting that high. Your re-application of the TIM sounds like it went perfectly, so good job on that. :)

Do you have multiple sensor programs open? (E-Leet, realtemp, etc?). Multiple programs can interfere with accuracy. Just open realtemp and Prime95, and nothing else. Now use Small FFT or blend, and see what happens. Large FFT can generate a lot of heat, and I don't think I've ever used that setting when stress testing.

Keep in mind, you will probably never reach those temps in real-life usage. Let us know what temps you get, and maybe take a screenshot of it, if you can.

Yeah, I wouldn't continue using that overclock if it is hitting those kinds of temperatures. What are your voltages set at in the BIOS? CPU, VTT, PLL, Etc.

You can also revert to the defaults and run Prime to see if its an issue with your temp sensors (sometimes you have to calibrate them with realtemp, I think...) or with the overclock itself. I can't imagine you'd be hotter than 50-60C while running stock.

I have never messed with realtemp settings, so I can't really help with testing how its reading the sensors. Maybe someone else knows more about that. Have you tried CoreTemp?

Just a few things to try...
 
Back the PCIE frequency back to 100.  There's rarely a reason to touch this, and some people have messed with it and claimed it helped with overclocking in SLI.  But really,  you can keep it at 100.  
 
Change the QPI frequency back to Auto.  You should have plenty of bandwidth there as it is.  
 
Your VTT seems a little high, and your CPU Vcore a little low..  While those are the voltages provided by the screenshots at the beginning of this thread,  you should really find the best numbers for yourself.  This is a tedious process, but every mobo/CPU combo will be different in this respect, so is you want the optimal settings, you need to do this on your own.    Or you can poke, prod, and guess at numbers in your BIOS and maybe stumble upon some cool, stable settings.  
 
This guide was helpful to me, but as with anything I or anyone else says....   Do it at your own risk.

If poking and prodding is more your thing,  I would back the VTT voltage down to around 1.3 and up the CPU voltage to around 1.35 or so.  You may require a little more VTT because of how much ram you have, but I never had to hit close to 1.4V when I was running 16 GB.
 
Which brings me to ram...  what kind is it?  A model number would help, as it seems your ram timings (and possibly voltages) are not set correctly.  I'm guessing your timings would be closer to 9/9/9/24,  with a voltage of either 1.5V or 1.65V,  but you need to check to see yourself.  Or post your model number and I'll tell you.   The biggest thing to remember about ram and VTT voltages, is that they MUST be within 0.5V of each other, or you can fry your IMC.  For example..  If you have your ram voltage set at 1.65,  the lowest your VTT can be set at is 1.15V.  Just make sure there's not 0.5V or greater difference between them and you'll be ok.
 
As a side note,  I read here that someone lowered their PLL voltage and it helped with stability.  That was definitely the case for me.  I didn't check it heat wise,  but if I can run something at a lower voltage and it makes things more stable,  I'm game.  
 
And a final thought.  If this is your first overclock, you may want to start with a lower goal than 4.0Ghz.  It's amazing how much cooler and easier getting to 3.8Ghz is.....  But as soon as you try for that little bit more,  all hell breaks loose.  Decide what your goal is, be slow and methodical (with a lot of reading), and you'll come to a stable overclock.  I hope anyway.  
 
Good luck!
 
 
 

So working in E-LEET for a little bit eventually gave me a BSOD, so I'll stick with going into the BIOS.

I noticed my RAM is 1.5v, so I assume that is the DIMM Voltage within the Frequency/Voltage Control section.

Also, because this is 1600MHz RAM, should I be changing the DRAM Frequency in the Memory Configure section to 1600 MGz? Currently it's at 1067 MGz.

BIOS set to "Optimized Defaults" and correct RAM settings in-place, idle temp is ~35C. Prime95 on Small FFTs gets up to ~55C.
 
I'll get around to working on re-doing the rest sometime tonight.
 

I just thought I would add that I had a i7-920 since launch day until Q2 2012 and I ran it at 1.58v cpu vcore and 3800mhz with average load temps around 90c - 93c during that entire time.  Granted.. gaming with an i7 @ 3800mhz, 95% of games don't load it above 20% cpu usage, which let it usually average 60's - 70's gaming.  But anyway, 4 years now at those settings.  No problems, No damage, No bluescreens.  And my friend I gifted the older overclocked system to is still using it today, still overclocked.  Still no blue screens, still no problems.
 
These i7 processors can take a lot more punishment than most folks are willing to do to em and it doesn't hurt em at all. Doing this may shorten the processor's lifespan yes, from the original 25 - 40 years down to 5-7 maybe?  I'm not sure but that 920 I started with is going on almost 5 years now, even under this kind of stress, and most people upgrade / replace their entire system after 5 years anyway.

You're right that most of us will upgrade a processor within 5 years, as this is an "enthusiast" forum.  You can probably keep your processor at 1.58V to run a 3.8Ghz overclock...  but why would you do that when you can achieve the same overclock with much lower voltage and heat? Why subject all of your other components to extra heat that is not necessary? 

Why punish a processor when you don't have to?  

 
 
Because sometimes when we buy processors, we get rather unlucky and end up with a processor that's very poor in batch quality and require that to do 3800mhz to be stable. I've been overclocking for years on intel systems, I only give them the voltage needed to be stable, and kept giving it a little more a little more a little more until it worked right, then it finally worked perfectly and it was fine for years and I never touched it again.
 
My i7-950 I have now only needs 1.42v to do 3800mhz, but needs 1.525v to be stable @ 4256 mhz.  And my 980x I've bought off ebay the previous owner told me already he's had it stable @ 4800mhz with 1.3v cpu vcore on water. It just depends on the processor and how lucky we are. I also have an Intel Pentium-D 930 dual core 775 cpu that can do 4588mhz stable on air with just 1.38v vcore.  Sometimes there's really, really poor batch quality in processors that need significantly high voltages just to do moderate overclocks.  Sometimes there's processors that are really high quality that need little to no extra voltage to do very high overclocks above 4ghz.  We just never know until we get in to it and try pushing stuff.

hi just checking in after a few years... p55ftw, i5 750,, 4.4 on water still tortured daily.. changed the water 3 times, gone through a couple raptor hd failures and upgraded a few gpu's over the years but it is still going..
getting ready to venture into the 4770k with either gd65 or extreme6 but i will leave this one going until it dies...
