3770K - Need a little help!

[flipout24]

Hi guys,

Looking for some help from someone more knowledgeable than I...

I've ran AMD systems for the past while so haven't OC'd much on an Intel Board. Have a new 3770K and I can't seem to find a roof for it, I'm afraid I'm just going to damage the chip in the long haul.

Most chips I find the point where it won't boot/post and work my way back from there. I can't find that with this chip. I have the VCORE set to automatic and it just keeps upping the voltage. I'm water cooled, posting and running Prime @ 5.2GHZ @ 86-88C. I haven't even tried to go higher than that because as is it's pushing the VCORE to 1.5, sometimes peaking to 1.55.

Can someone give me a decent multiplier, voltage and temperature to shoot for so that I don't end up burning this chip out after 6 months...

Thanks!

Holy smokes thats a crazy amount of voltage for that chip. I don't own that chip but I think most guys like to run in the 60's at no higher than 1.3v, I think the max temp is 105 before thermal throttling and around 1.52 is absolute max voltage.

Your in the fun to play around zone but not safe for 24/7 as most would say.

Around 1.4v's should be safe enough so just see what you can get out of it.

Intel offers insurance plan for overclockers if you just wanna go balls out with your cpu. It's reasonably priced at $25 for your chip

Your temps are fine under sever stress testing. I wouldn't worry about it.

I've had my chip up to 5.6ghz at 1.7v's and it's still kicking along just fine. I was more worried about blowing the caps off my motherboard

At this point I would suggest you start manually lowering your voltage and see how low you can get it stable. It might be worth losing a hundred mhz or two to get the voltage down a bit.

Sandy and Ivy chips are insane, eh?

You're already way past the roof on that card. 88C water-cooled at 1.55v? The chip won't last long, regardless of whether it's currently stable. Frankly even 1.4v is probably too much for IVB - that was the ceiling for SB.

Ivy Bridge can last at 88C without any issue. At that voltage, electromigration may be a problem, but temperature clearly isn't. Try manually setting the voltage instead of using the automatic setting. You may not need that much voltage to run over 5 GHz.

I think you'll find that if you want to get in the good zone you'll need to drop down to 4.5-4.6Ghz at around 1.27 - 1.35v.

Not much more to offer here . . . Some of us obsessed over "safe range" voltages -- which were a subset of "operable range" voltages. Those things were once provided by Intel until -- I think -- Nehalem. As the die-size shrunk, so did either the spec'd or "speculated" safe-range upper-bound.

So it's mildly interesting (only to me) that I "guessed" IB to have a practical upper limit of 1.30V, and someone here suggested the same. We'd "agreed" or approached a consensus that 1.35V was a safe upper-limit for SB, but pushing it a tad above or as high as 1.4 seems to be acceptable. 0.05V is <= 4% above the 1.35, so probably not to worry . .

If I were building my own IB now, I'd try to keep the voltage down to "around" 1.30 but maybe accept some overage -- maybe 1.32V. There just aren't any formal guidelines published at Intel on a "safe range" for these. I could be corrected, but . . . what we have . . . is what many here only "suggest" . . .

If you use near 1.4 or so it might start reducing MHz at the same volts in a year or so, maybe less. 1.3 or less is perfect for 1-2 years or so without changing any setting with high end cooling. Since you have custom cooling you should stay within 1.3-1.35 for it to last around 2ish years or so.

And I am talking of the bare minimum it would last. It may even last twice as long or even longer, but this is nearly guaranteed with such settings.

His temps are great considering vcore and overclock..

1.4v's @4.8-5ghz with temps in 70's under heavy stress testing isn't gonna kill his chip quickly if at all.

If it was me I'd try for more before settling on 1.4v's

 

[flipout24]

Thanks for the help guys.

It's nearly stable at 5.1GHZ @ 1.4v. Windows isn't blue screening or crashing, but Prime does randomly crash after a few hours. 1.4 also brought the temps back down to a more reasonable 72-75. For some reason my core #1 always shows several degrees higher than the others, which I just don't understand. For example three cores are showing at 68 while core #1 is showing at 76. Seems to change but it seems to stay at least 4 degrees hotter under heavy load. All the cores show the same under mild or no load.

Thanks again!

Heat isn't an issue here. You're 20 degrees off of Ivy Bridge's thermal limit. What you need to worry about is electromigration - as transistors become smaller, the issues related to it become more significant.

Drop the speed to 5.0 GHz and get it stable if you can. That's still a 43% overclock from stock. I remember when a 12.5% overclock was good, much less 33%.
