I'm confused on one thing though. So, my CPU temps spike up when I'm idling. Doing nothing, not opening any programs, just staring at my monitor, temps are in the 30s. As soon as I open a program up, it shoots to 40-50C. Is this normal and is it some feature implemented in IB or is something seriously wrong here?

Another issue I have is my temps in Real Temp TI when doing a P95 run seem to get stuck. I've ran the tests three times, all with different settings in P95, some more intense than others, but still 5-10 minutes in my temps are reported 81-87-85-78. It goes no higher even though when running IBT a couple of months ago got me 90C+, the temps are stuck at 87C max.

Sorry if that is worded very poorly. I'll get some pics if it wasn't clear.

You really shouldn't use IBT on Ivy Bridge. It's designed to get your temps higher than other apps under 100% load. I use it as a benchmark of "Even worse than the absolute worst case scenario" but you should be careful. When your chip is idle it's not doing anything. So of course temps will be lower. Also depending on if you have speedstep enabled this will be more noticeable. CPU's get Real Hot, Real Fast. So if loading an application requires higher CPU usage even momentarily, you will see that spike in temps. That's not an issue. However....87c is still way too high. You don't want that.

While ivy bridge is far less prone to degradation over time when compared to sandy bridge, I would still be *very* concerned about a 90c operating range. Ideally you want temps to be no more than 75-79 at the absolute highest end of the spectrum. Whether you accomplish that through lower clocks/lower voltage, de-lidding, or using a better cooling solution is up to you.

Just so you understand how high 87c is....this is a picture of my CPU on IBT at 1.608v. Don't *ever* up your voltage this much, btw. The point I'm trying to get across...is that your temps are even hotter than my CPU would be at 1.608v. That's ridiculously hot. Don't do it.

Thanks for the explanation. I should probably just stop using IBT. I only use it to see if my Gflops are good. And also good to hear that the temps going up when I load a program is normal(I do have Speed Step enabled.) I don't know if there is much I can do about the temps though. A year ago my temps were under 80C running the same settings as now, but they've gone up over 10C for whatever reason. Part of it may be because it's summer, but I think it's just that my CPU isn't normal. A few months ago Real Temp was showing my temps being in the high 80s while being at stock. The issue eventually went away but I still think that's what's happening now. I really don't think I'm at 87C. I don't know if the sensors have just gone crazy or what, but if I get annoyed by it enough I'm definitely going to RMA. Because even now Real Temp shows me temps in the high 60s being at stock. I don't even think the stock cooler can get that hot. And it's definitely not my D14. I've tried using my EVO 212 with the same results. Also not the motherboard as I swapped it out and got the same results. I am also applying paste correctly using the pea method.

So I was able to achieve a 4.3 multiplier with +0.005 offset and +0.004 turbo. Is there any difference between the "Green Overclocking" and "Starting Off" section? They both try to find the highest stable multiplier with a +0.004 turbo o_O

Is it normal for higher overclocks to require a lot more turbo voltage? I tried overclocking to 4.5 and I've upped the voltage a lot and it still isn't stable in P95.

How long should I run IBT and Prime95 to test stability? Is there any difference between the two? What settings of IBT should I do?

Sorry for all the questions, I want to learn more about this D:

Sorry for all the questions, I want to learn more about this D:

The difference between green over locking and normal is green means you will never increase your voltages... its about achieving the best with lowest possible voltage. Otherwise you step up your voltage to achieve better performance.

Its normal for higher over clocks to require more voltages than you think. I've just stabilized 4.7 on my 3570k at +0.055v Max temp in p95 was 79, in IBT 85. Yet for 4.8 it was +0.113v with a Max temp of 84c in p95 and 92c! In IBT.

I have tested with P95 following the settings in this guide, however 1st I run P95 for 20-30 mins. If that passes with no errors (check for WHEA errors too)

In IBT I run 10 cycles at stress level maximum. This helps see your Max temp... watch this carefully. If that passes and the temps are Sub 85c and errors I run P95 with settings in the guide but use 90%+ of memory instead and run it for 9-12 hrs... if you have no errors and no WHEA errors I would call it likely to be stable enough for every day use.

Ok guys I think me suddenly needing more voltage may not be because of degration or my settings are wrong, but maybe because the new 2.90 BIOS is funky.

Can I flash back to 2.80 normally as I'd do if I was updating my BIOS? Don't want to mess anything up by flashing to a previous BIOS.

I think my z68 is holding me back. redface.gif

4.6 stable @ 1.256v but anything over 4.6 I got WHEA and looks like i can't get it out somehow.

More voltage hasn't helped? My old 3770k needed 1.42v for 4.7ghz. Try increasing voltage slowly.

There's no harm in flashing to an older BIOS version.

If one of the cores stops working in P95 after 2-3 hours is that something to be concerned with? Or should I just increase the turbo voltage by one more step? And is VID different from Vcore? I notice that there's a big difference in the 2 values, I get my VID from Core Temp and Vcore from CPUZ and CPUID. Which value should I be watching out for more carefully? My LLC is set to level 5 btw.

Thanks. Went back to 2.80, everything is normal now. Still getting 85C on one core, but at least I it's stable.
