Need Help/Suggestions with my i7 3770k Overclock (I'm pretty new at this!)

post #1 of 28
Thread Starter 
Hey guys! I'm making this thread because I have some concerns with my i7 chip which im not sure if I should be worried about.

I am having what I believe to be uncommonly "high" tempereatures when I run Prime 95 for more than 15 minutes (I'm not even sure if this is neccesary seeing as all I really do is play games, and I have never really had any problems with temps or performance, as far as I know).

Some things to note: (Will be editing as I try to fix this)
* i7 3770k
* Clocked at 4.5ghz
* I have my V-Core set on Offset Mode at 0.015+
* LLC 50%
* PLL Voltage set to Auto
* Spread Spectrum Disabled
* I have turbo boost voltage set to 0.023+
* V-Core peaks at 1.32v at 100% load
* Room temp is 25c
* Cooling: Antec Kuhler H20 920
* Running everything on a ASRock Z77 Extreme 4 motherboard.

Anyway, after 15 minutes in Prime 95, my temps shoot up past 96c, with the cooler's fan set on "Extreme".

Also, my idle temps SEEM normal. I idle at about 30-35c with the cooler's fans at around 1200-1400rpm.

My highest load temps that I have gotten while playing Arma II have been 65c, with the V-Core peaking at

While playing Black ops 2 I get around 56-58c.

So yes, my question is, what do you guys think of these temps? Should I be worried about them? If so, what solutions do I have? Is my chip defective? Or did I simply get a "bad" chip?

Thanks! redface.gif

EDIT: (Will update frequently)

Are you sure the cooler is mounted well, and working at full speed? I'd expect better temps from that cooler.

I actually changed my turbo voltage to 0.027+ and I ran this custom p95 test for 1 hour: http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition#

My max temps were: 85 90 90 85, but they never went over.

And yes im sure it is mounted well, I re-seated it like 2 times, and it made no difference... i probably just have a ****ty chip haha. Gotta learn to live with it I guess.

Question though, do you think that with those temps I would be able to safely play games?... my temps dont get anywhere near those temps while I play :/

Well 4.5 is average and alot people.now I noticed get 4.5@1.3 so I would say average. Also before I delided I would see mid 90s at 4.5 , I would remount and if that doesn't work you will have to delid to keep that overclock. You should also always run prime for 12-24 hours you don't wanna loose files or game data because of a system.crash, and it will tell you max temps as well.

here is a screen shot of my temps at voltage at 4.5ghz. Also using an offset of .015 like you will LLC second highest setting, using all powersaving options. In this screen shot this is about a 4 hour test of Intel Burn Test(IBT) on max setting using 15gb out of my 16gb of ram.

What do you mean by "delid" Literally remove the lid?

And I know the whole prime 95 craze and what not... but is it REALLY necessary for gaming? I have let it run for tweleve hours at these settings, and once agin, my temps peaked at 96c. Not sure for how long because most of the time while the test would run, it would hover at around 75c.

Slow down please... lol... how the hell do you get those temps? haha

What kind of cooling do you use?

And what settings do you use besides the 0.015 offset? Because my peaks are way past that in prime95...

Is intel burn more forgiving than P95?

With that speed and voltage your chip shouldn't be running at 96C. If it is normally in the 70 range, which is what you'd expect, it could have just been a reporting error or glitch of some kind. I wouldn't worry about it - just keep an eye on it while you are gaming and make sure it doesn't happen there. You can also try running IBT - it tends to get the chip a little hotter, so it might be quicker to reproduce the problem.

ok sorry I will slow down.

1. you need to test even if your just gaming so you know you system is stable mainly

2. 15 minutes of prime will not give you max temps but close to them.

3. you want to keep your cpu at 85c or under during stress testing.

4. you want to keep you voltage at 1.35v or less.

5. to delid there are threads just for that, and yes it is taking off the IHS and applying new TIM to the die of the cpu.

6. my rig is posted I am using a H100

7. I use offset of +.015, LLC ultra, phase control extreme, pll voltage 1.7v, all ram timing and voltage I set manually to run stock. multiplier of 45, disabled speed spectrum other than that everything else is left on auto.

8. so if you want the truth usless you build a custom loop, or delid I would not run your cpu the way you are doing it. But some will run theirs up to throttling because they won't get that high in normal everyday use. you will have to play with the settings and find out where you feel safe. You might be the guy that buys a new cpu every six months or you might want it to last a while. Bottom line is your chip is a average overclocker that needs to get a delid or try your luck with another 3770k if you have the cash and sell the one you have.

9. also don't forget to reset the cooler you might still have a bad mount.

10. Lastly you might be stable at 4.5 at a lower voltage as you have only tested for 15min you still wouldn't have know if it is stable or not, you are going to have to keep playing around and find proper voltage at that clock.

He said he ran it for 12 hours, and it was normally at 75C, so it sounds like something weird is going on. I've never seem 20C spikes on Prime before - normally it hovers in about a 10C band.

Yeah, my chip usually runs at 70-75 while under full 100% load.

and 60-70c while playing games

but as soon as it finishes the first round of tests in p95, the temps fly up, but later, after a few minutes, stabalize again.

and no, after running prime for 12hours i recieved no errors whatsoever. just high temps.

Make sure the voltage isn't spiking at the point where the temps go up - maybe there is some kind of a huge voltage overshoot going on when Prime switches tests and momentarily reduces the load.
