I built my system about 2 days ago, and I just got around to overclocking it, knowing the 3770K's penchant for getting real hot real quick, I took it slow.

I auto-overclocked to about 4.6GHz using Asus's Mobo software, all stable, all good, but I noticed my temps were hovering around the 40s, so I decided to push a little further. I managed to get to about 4.8GHz, and 67-70C on all cores, with the processor at 100% usage while stress testing.. Is this normal, because from what I hear, my temps should be around 80C?

I'm cooling with a Corsair H100, only 2 fans, stock TIM.

 

What do you guys think of my voltages? 1.376V-1.4V

I'm running a 105BCLK, and a 46x multiplier.

 

Here are my temps under 100% stress

 

And here are my OC settings:

 

 

What do you guys think I should do?

Push further? Get the magical 5.0?

If its a 100% then your good, your H100 is probably doing its job, I have heard from friends of mine that 70c is probably the hottest you want to go, as the ambient air temp does effect it as well.

 

Phill

Huh.. Because I wanted to know if I could push it any further. 4.9, maybe 5.0 with some luck...

I thought 85-90 was the most you want to go with the Ivy Bridge chips..

i am conservitive on my set up, as i never wanted to toast my chip. i should have worded it differently, i would not want to run my set up at 80 or 90c for any length of time, and deffenntly not the life of my comp. But you could also try it and see, it may not go up that much more as you really only going up .1 to .2 ghz

Huh, but the thing is, realistically, there are no applications that would run your chip at 100%.

 

Then again, FSX is FSX, so, I'm not so sure..

 

I'll push for 4.9, maybe 5 tomorrow after stability testing overnight.

Don't know if you are flying any of the tubeliners in FSX (e.g. NGX). If you are then you are probably aware of the whole derated / assumed temp thing during take-off. Sure, those turbofans can generate a lot of thrust (and heat) but no-one ever wants to run those things at max power for the entire flight. Maybe a fully loaded T7 out of LAX bound for Sydney would use max T/O thrust but that would not be for very long.

Same with your i7. It can run hot but you'd be seriously lowering it's life expectancy. Unless you're someone who likes to push the limit and get fixated on the tiny differences between the various o/c timings imvho it would be preferable to keep that cpu at the current cool-ish temps you are getting and enjoy your flying.

 

Personally I am far more concerned about correct technique and procedure rather than fret about my fps not quite making it to the magical constant 30+ or about the occasional micro-stutter. Plus those 3770s are a pricey chunk of silicon :wink: . Wouldn't really want to brick it before its time!

Hahahaha, yeah, I do fly the NGX, and I get what you're saying.. Fair enough I guess, I'll probably just stick to what I've got..

I think its a wise idea and you have gotten a very good OC without doing the delidding

What is your "stress test"? I use quotes because you're not really stressing your chip with the temps you've shown, not a chance. You need to use a program like Prime 95 w/AVX support (read: version 27 and above) or Intel Burn Test to get a real idea of a stressful situation. I hit low-mid 70's on my 3770k but it took a de-lidded chip, liquid metal TIM, lapped IHS and water block, and a custom water cooling solution to achieve that. Now if you're talking about FSX as your load scenario I could see that, maybe. I probably hit 50's in FSX @ 4.9GHz.

I'm actually using IBT, 20 Cycles at Ultra High, and 4.7 @ 1.275V passed without a hitch. Temps were about the same, maybe 5*C higher, and it peaks at about 74*C.

 

The weird thing is, IBT said my system is perfectly stable, but I left it on overnight last night, no tasks open, nothing happening, it was just idling, and at about 7AM this morning, the windows crashed (no idea if it was a BSOD, woke up to my system shutdown, when I booted it back up again, I got the splash screen asking me if I wanted to boot into safe mode because windows experienced an error.) What d'you think might've happened there? It was idling, it really shouldn't have crashed like that.

 

 

EDIT: It doesn't seem to be a BSOD, according to Blue Screen View, there was no reported BSOD since my last failed OC attempt, everything looks normal on that front.

I just bought a 3770K (come on UPS!) and can't wait to put together the new computer but I won't be worried about pushing for 5. I'm going to move nice and slow to 4.4, run that on Prime95 to make sure it's good, watch the temps, and if they're sweet that's where it stays. If I can't run FSX at 4.4 I don't want it. I just spent $329 for that chip and whether FSX will run or not, I know that Lightroom, Office, and Windows will. So, a nice 24/7 overclock is good enough for me.

If your cooling is good enough, 4.6 should be well within reach for a 24/7 OC. I get to 4.6 on the auto tuning software bundled with Asus boards, which is pretty awesome for an automatic software.

So, a nice 24/7 overclock is good enough for me.

 

If you have 2133MHZ RAM paired with a 4.4-4.6GHZ overclock on your 3770K, you will run FSX very smoothly.

Hey Ben, I'm frustrated to my wits end.

I have a 2x4 set of G.Skill Trident X RAM. What do I set my RAM speed to?

 

And I haven't been able to get my FSX running smooth at ALL, very stuttery :@

I followed Word Not Allowed's guide to the 'T'.

 

NGX @ EHAM, Most of the sliders to the right, and 50% AI, I'm getting massive stutters and about 17FPS. Normal?

Something is not right.

 

I have three X 24 Dell monitors + a 4th monitor. And even at EHAM with NGX with UT II AI 100% I get only 11 FPS, its still pretty decent... no stutters... except for the obvious 11FPS that is visible by the eye.
