my 3770k requires really high voltages? temperatures too high?

[mr bee]

I've been trying to get a higher overclock from my 3770k but right now I'm stuck at 4.5ghz with the lowest stable voltage of 1.31 (reported as 1.322 in bios and 1.296 in cpu-z) and temperature averages 92c.

I've read this MSI board generally requires higher voltages, but 1.31 seems a little too high, no?

I would like to get 4.7ghz out of this CPU but I'm going to have to get that 92c lower before I push ahead.

Any ideas of what to do next?

My specs:
3770k
MSI Z77A-GD65
corsair H100

IB gets really hot past ~1.3v.

Why do you want such an aggressive OC anyway?

You probably have a lemon Core i7 3770K. My Core i5 3570K does 4.5GHz@1.28V and from what I've seen, Core i7 3770K needs less voltage compared to Core i5 3570K at the same speed. Its also possible that your voltage requirement increases as you need more voltage to keep it stable at a higher temp. Mine does about 75C max on any stress testing(LinX, IBT, Prime95).

At that temps, you shouldn't be doing any more than 4.5GHz. The Corsair H100 isn't as good as similar 240mm rad custom loop. Also to note is the ambient temps. If it is hotter where you're at, your idle and load temps increases with it.

I'm running a really intensive single threaded game server that will benefit from it.

Ambient temps are 25c

I'm running the 4.5ghz overclock now, and it's running well at 60-70c with one server process. It'd be nice to get the temperature down so I can run two or three.

Should've gotten a 2600k?

70C shouldn't be an issue. Whats the temp like running 2-3 server instances? If it is in the near 90C range, it shouldn't pose a problem as the TJMax is 105C.

Try setting the Corsair H100 on performance mode or orient the fans to intake cool air instead of blowing hot air from the case.

 

[aaksheytalwar]

Even I need $1.25V (or above) for just 4.3GHz. 4.4 needs a lot lot more.

Sounds like de-lidding is your only viable recourse. May or may not hit your 4.7 Ghz target but you'll certainly get lower temps at whatever you do hit.

 

[WhoBeDaPlaya]

Ouch, sounds like silicon roulette. My first 3570K was downright horrible (needed 1.22V to reach 4.3GHz ). My second 3570K is much better (4.5GHz at 1.18V).
Both of these were fixed Vcore overclocks with all shennanigans disabled (C1E, EIST, C-states, Turbo, etc.).

 

[Ferzerp]

Your 3770k is as bad as my 3770k!

 

[Rvenger]

My 3770k does 4.2ghz at 1.17v and 4.4ghz at 1.22-1.24v. Average chip I guess. Temps get hot though.

 

[GPz1100]

3770K @ 4.6, + 0.050 in offset mode. Vc no higher than 1.30V per cpuz/aida when under full load (prime95/IBT). Temps under 55C at full load, idle 22-35C. Delidded and water cooled.

I could probably have gotten away with an even smaller voltage offset increase, but my patience is limited, and thus far this setup is fully stable with no bsod, locks or crashes since being configured this way ~2-3 weeks ago.

about the same here
- but not delidded
-4.6 @ 1.3 v not really tweaked either every time I go to do so a new bios comes out and I hold off for feed back on it.,stable for 3 months .

-using the offset mode also but maxed windows 7 power plan to idle at x35. didn't like the x16 to x46 every micro sec.

-no problem with temps [water @ 20c under load]
no regrets on this build

Can you expand on this? You don't mean the cpu temps are @ 20C, but rather the actual temp of the water is 20C?

Unfortunately I have no way of measuring the water temp itself here (though it would be interesting to compare). It's not even warm to the touch, so I imagine it's somewhere near ambient, which is ~22C (71F). Not overly concerned about water temps yet. We'll see where they are next summer when it's 90F outside and close to 80F in here.

The Ivy Bridge K chips seem mostly limited because of the way the processor cap is mated to the die: no fluxless solder, just TIM. Watching what people have posted here over several months of this year, and keeping up with IDontCare's two "delidding" and bare-die TIM-testing threads, I'd have to say an "enthusiast" would be limited without taking the risk to de-lid the processor and at least use a different TIM.

I wouldn't buy one now unless I were building a system for the fam-damn-ily with no tweaking or OC'ing (and probably not a K chip). If I bought a K model for OC'ing, I would count on a delidding and TIM replacement project.

It's been on my mind a lot, but I haven't found a place for it in my budget so far.

 

[mr bee]

I got another 3770k + ASUS mobo that I haven't tried overclocking yet, will try swapping the CPUs and comparing overclocks on both mobos.

Is the NT-H1 the recommended TIM for lidded CPUs?

I like NT-H1, works well.

-to monitor water temps in a loop there are cheap $10.00 sensors that mount in a spare port in the system.they can be plugged into a fan controller that have temp. monitoring ,

-they won't be spot on for that price but I just watch at boot the temp read out vs room temp giving a offset eg -2 or + 2c in my system

-the 20c water temps.comes from having the rads [ 3 x 320 +9 fans @ 1600 rpm.] in a stone foundation crawl space that is cold all year .

-IBT max setting @ 4.6 will still hit low 80's ,but gaming is still 50-60c

Rgallant, thanks for following up.

Just going over your specs and comments in post #12.

Seems the main difference is the delidding which is playing a major role in our temp differential. It all goes back to the same conclusion in the delidding thread itself. No matter how good your cooling solution (and yours is differently cooler than mine), if the heat from the cpu can't transfer to the cooling block, the cpu will continue to run hot.

This explains the 25C+ temp difference under load. Mine at best will hit 53/54C on the hottest core with IBT max settings @ 4.6.

Suppose it boils down to what one is comfortable with and what one is after. For me this whole build was an experiment of sorts. I've never done a watercooled setup before, nor have I purposely voided the warranty on a perfect good cpu.

ymmv

your temps are really great.
-delidding for me could be a option in the future .

-but on the gpu side of my system , my 580sli @ 900 never go over 36 - 40c benching\gaming.

can't think of hardware coming in 2013 that will require a upgrade , so till 2014 I should be ok.

 

[Mike89]

Delidding just makes no sense to me (with the work involved and losing the warranty). I have my 3770k running 4.4 gigs at 1.17 volt at load at around 65c. That's plenty good enough for me and I can hang with that all day long. I don't have the need of some of these overclockers to have my system running right on the edge of destruction all the time for what I use my computer for. My brain can't wrap around that concept. For me I don't see the necessity of any negligible performance increase from 4.4 gigs to 4.7 gigs that would warrant the extra voltage and heat. But that's just me.

That temp sounds normal for ivy bridge. Generally I would aim for 4.4-4.6 with ivy bridge, which should match up well with a 5ghz sandy bridge.

In other words, if you need that much voltage for 4.7ghz (that isn't unusual) i'd stop there or scale back a bit. My IB needs high voltage as well for 4.7ghz, so I just do 4.6ghz at 1.25v.
