Actually, it's not recomended to use MB automatic OC options. And there is a good reason for that - automatic OC option will set your Vcore to some ridiculous high values(which means high temp and very bad for CPU, worse than much higher manual overclock) or will set Vcore to "auto"(very bad too). 

 

When i started to learn about OC, i tried automatic option. Assus automatic OC tool was sent my Vcore above 1.7V for 4GHz! after that i uninstalled it, and i said - never again!

 

I have now stable 4.8GHz with Vcore 1.4V for 8 months, after spending about two weeks on reading and testing.

 

P.S. There is no problem with 5GHz if you do everything right, i'll go there after i change my cooler. 

 

I'll try to upload my BIOS settings later and give you some tips for which i needed 2 weeks to find  ^_^

Thanks everyone for the help and insights; it's really appreciated.

 

I checked my fans and I'm pretty sure they are running fine. The H100 fans are running around 2200RPM. 

As mentioned above, it seems like you might not have seated the cooler properly. Either that, or you got a chip that runs really hot. I am using a cooler master hyper 212 evo, and am at 4.2 with the same chip as you. During an hour of stress testing, my temps never went above 78 on my hottest core.

Cooler is not mounted properlly or is deffect, that's for sure. You can't get so high temps with H100. I'm getting lower values with IBT test with Air Cooling

It seems to be seated correctly but I'll double check.  I'm not sure how quiet the H100 is but I only hear the fans on the radiator.

• stupid question but have to ask, does the H100 has water on it?

It does.  

 

So, I kind of blame myself for this problem and high temps.  I can't believe I didn't check this before but I looked at temps while doing a flight.  I'm up in the high 60's low 70's (no OC).  

 

I have a feeling it might be a bad h100, although I can't say for sure.  The fans are running very quietly for having such high temps.

 

What a pain in the a$@.  I've been plagued with small problems with this new build, had to return a bad PSU about a month ago.

 

Oh well...thanks everyone for the advice.  I guess this really isn't a OC thread anymore.

check the thermalpast   (just a guest ) running on  hyper air cooler 50c  max

Temps that high are definitely a malfunction in the cooling system. See what your temps are in the BIOS. Go to the hardware monitor section and watch the CPU temps. If they get above say 50 degrees C they're way too high and something is wrong with your cooling system. With no real thermal load your chip should be idling somewhere in the 20's to 30's in the BIOS. Best guess is it's not seated properly, probably not making good contact with the CPU. Could be something wrong with thermal paste as well, say for example if you removed the stock pre-applied thermal paste from the H100 waterblock and replaced it with your own, if you put on too much you're just smothering the CPU and holding the heat in. I'd remove that waterblock and be darn sure it's installed according to instructions. You can take the waterblock off and check the thermal paste footprint to see if it's getting good contact or not, just look for a nice square coverage of thermal paste on both the waterblock and the CPU.

Well...this might turn out to be an OC thread after all.  I removed the H100 cleaned everything thoroughly and carefully reapplied my Artic Silver.  I'm idling around 20-30.  I loaded up FSX in an intense scenery area and didn't go over 40, I only did this for about 15 min. but things seem to be so much better.

 

Now it's back to the original intent of the thread...OC.

 

Thanks everyone for the ideas.  I wouldn't have figured it out without  your help

Artic Silver

 

should be replaced about every 3 months fyi - great news.

Apologies if I have you wrong but it looks from your post that you are recommending that Arctic Silver should be replaced every 3 months, you may have this confused with the fact that it can easily take Arctic Silver this long to be properly cured - http://www.arcticsilver.com/as5.htm

 

"During the CPU's initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability."

 

200 hours equates to 2 hours use every day for 3 months, you wouldn't want to be removing it and starting again just when it's reached it's most effective state. 

For FSX, it comes down to two things:

1.You can easily, in a few minutes, overclock an I5, i7 or the new Ivy to 4.5 Ghz with almost any motherboard that offers overclocking and a $30 air cooler. This will give you decent fps, by decent I mean in the 20's.

 

2. You can become obsessed with 5 ghz and spend money, time, and patience, hoping to get there.

I call this chasing Frankenstein.  Once you catch the bug, you can never let go. 

The fact is that 5 ghz is still in the realm of folks who are willing to spend time and money to get there.

Many of them can tell you that they've destroyed components in trying to get there.

 

 

Since you're asking the question about oc, I assuming you're just starting out. I would then relax and go for option 1.  This will make the decision quite easy for you.   Later on, if you're lucky and adventurous, you can try to go higher and, who knows, you might get lucky.

 

In my case, I am happily running at 4.5 and all I had to do is use one of the motherboard's options to do all the overclocking for me. Pure and simple.

I second that advice. Very well articulated. Fsx is fickle enough without also having to deal with an unstable overclock. Was easily able to achieve a stable 4.5 Ghz overclock on my I7 3770K doing nothing more than changing the multiplier in BIOS on my Asus Z77 mobo and let the program configure the rest of the settings. All of this was done using a $30 CM Hyper 212 EVO with 2 fans in a push pull arrangement. Make sure your heatsink is properly seated and thermal paste is properly applied. Not doing this correctly will send your temps through the roof. Good luck!

So, I took it up to 4.2 and it really was easy.  Seems as though I overreacted a little, but it can really be overwhelming when surfing the net on the subject.

 

I'm away from my computer this week but will take it up to 4.5 when I return k and leave it at that.  I have no desire to play around with it above that.

 

Thanks everyone for the all the help!!
