I can get 4.9 GHz stable with 1.36v stable through IBT. However, if I run 5GHz with 1.4v, it still won't pass IBT. Any tips?

There might be ways to get it working, but I don't think that 1.4V is a very safe voltage for those CPUs. Have you checked your temps?

Yeah. It jumps to a 100 when running IBT.

Cause Ivybridge runs 20C hotter when overclocked.

True dat. I was going to get an i5 2500k but microcenter doesn't offer the bundle with the 2500k.

4.9GHz is probably your limit. It's a good frequency anyway IMO and is roughly comparable to i5-2500K at about 5.3-5.5GHz. It's a little higher than I'd expect you to get, what cooling are you using?

Kuhler 620. $56 at Microcenter. Woot. Would disabling the powersaving features in the BIOS help?

That seems perfectly reasonable to me for a chip that ships in the 3Ghz range

Looks dangerous. Why didn't Intel do that in the first place?


The same amount of heat gets dissipated into the environment regardless of whether or not the CPU has a solder attached IHS or is simply using thermal paste. Thermal paste is much cheaper and is easier to manufacture. It was a cost and time saving measure.

Overclockers are very small minority with respect to the total size of the microprocessor market, so a global cost saving on that scale is far more important than a few grumbles from a tiny but vocal minority that despite their misgivings will still go out and buy the products in droves.

Tips: Better Cooling or, better cooling, or better cooling, or be satisfied with the results you have, you're already further than the majority have gotten with the IB.

Removing the IHS is a instant warranty void, I'm sure you know that right.

Alright. Is there a way to add on another fan to the 620? I already have all the fan slots filled in the NZXT Vulcan.

There is always ways to add another fan somewhere, zip ties come in mind. you could use a fan cable splitter to hook 2 up in the cpu fan socket if thats what your asking :) 

Though from what I've seen temps don't change to much going from one fan on the heatsink to two.

Would it be possible to just leave it at 5GHz with 1.36v because the reason the CPU turns off is because it reaches 105 at 5GHz, 1.4v?

If it was stable without the temperature bottleneck that is.

Certainly, just don't stress it or do anything to get it unstable, but I would just put it back at 4.9 and be happy. 0.4v increase for 0.1ghz of performance just doesn't seem like a happy ratio :)

The fact that its hitting its thermal shutoff point tells me that you're in over your head. If you're not careful you'll end up with a 0Ghz paperweight

Agreed!

Or an overclocking badge of what not to do!

When I said Better Cooling, I meant way more than adding a fan!

You've got to get the CPU core temperature much lower, if you are determined to run 5.0ghz, there's no present need for you to run above 4.5ghz anyway, and you'll be a lot cooler and your CPU will last a lot longer, if you lower your sights.

It only reaches 105 when I run IBT though, and when gaming, it doesn't seem to get anywhere near that.

Lol. Alright. Is it better to keep it at 4.9GHz with 1.36v or 4.6GHz with 1.32v?

I'd go for the 4.6GHz at 1.32V, but that's me.

Pushing the limits is a lot of fun, and you always have the chance to win free hardware if you upload your benchmarks in competitions.
You should check out Thermoelectric Cold Plates (TEC)
Using a cold plate/water cooling combination you can get sub zero temps!
And the set up looks SWEET inside your system

wouldn't that create condensation though?

***EDIT***

4.9GHz at 1.32v. Stable through IBT.
