I've seen quite a few oc's on these forums and not many chips are so bad as to need 1.45 to hit 4.7. That is most likely the source of your high temps.
try backing off your turbo to about .120 with level 2 LLC. That should give you a stable clock and reduce your voltage and therefore temps drastically. Also, make sure and run P95 at LEAST 10 min if temps are good in the first part of the test. The temps you're seeing within 5 min will increase 5 to 10 C from where they are. I know the guide says a quick 5 minute test to see if the oc is somewhat stable. However, that's just a quick check and won't guarantee complete stability under load in real life scenarios.
Personally, I try to stay away from voltages from 1.45 to 1.5 cause I'm a bit paranoid about degradation of the CPU. When I tried voltages over 1.4 my temps went nuts, even with the custom loop I have. Some chips just behave differently with different volts. My sweet spot seems to be right around 4.8. I can get that with decent voltage and pretty good temps. It just takes some time/patience/experimentation to zero in on the best clock/voltage for your CPU.
You may also try reseating your heatsink to make sure that you've got good contact. The pea/grain of rice method seem to be the best when applying thermal paste. I recently did that myself and got it running a couple degrees cooler. Here's a good video showing why it's better than spreading the paste over the CPU. By the way, what cooler are you running? Don't remember what you said you had.

Those temps and voltage were after a 10 minute test. My computer refuses to boot to windows when my turbo is too low which is why it ends up being so high. Should I try adjusting the PLL?

yes its the UEFI that came with the motherboard i did get AsRock to send me an updated CMOS chip to support Ivy bridge is there an update to the UEFI i need to download as well? The system is the one in my Sig, so P67 Fatal1ty Performance

If you go to page 159 of this thread, you will see several postings by Lucky23, and one of them includes all of his settings. Now that's for a mobo like mine. But if you read the actual posting where he shows his settings (there are a series of screenshots of his UEFI), he passes on what IMHO is some sage advice about overclocking these motherboards. One suggestion in particular is to simply leave turbo voltage at auto. Good luck. Time for me to wrap packages.

What is your ram voltage at? I've read before that the VTT setting and your RAM should be within 0.5 of each other for best stability. You can try raising your PLL as well. But do one first and then the other.

Edit: That is a good suggestion with the auto on the turbo. Try that and see where your voltage is or see if it even boots with that.

I am not familiar with the P67 chipset, so I'm at a bit of a loss here. Is there a forum here at overclock.net for the p67 chipsets? But to hazard a guess, is there an updated uefi/bios for ivy bridge chips? There might be, you would have to check with ASRock.

Way back when, I built an AMD system with a venice cpu, and it worked only marginally until I flashed a new bios, and then it worked fine.

Sorry I cannot be of more help.

At 4.7 I tried it with Turbo on auto and only adjusting the offset. At the lowest levels of offset it refused to boot at all and everything from then on was unstable... I got up to .170 on my offset before I gave up. P95 either refuses to stay open or it produces an error on its worker #2. I stopped adding offset because my voltage was up to 1.45 and you mentioned it shouldn't be that high to get 4.7. I tried adjusting my PLL up and down with no change in effect, I tried changing to level 3 and that allowed me to adjust the offset higher, but I was still having unstable issues.

To answer your question about my VTT/RAM voltage, my RAM is stock at 1.5v... the VTT was on auto and much lower so I bumped it up to be within .05v like you said.

I don't know what else there is that I can do. I followed the guide exactly as it says, but I'm just not getting stable results. I'm not sure if it matters, but the values in my short and long durations are 500, I typed in 10000 in each of them like the guide suggested and they all changed to 500 upon pressing enter. I've noticed screenshots from other people where their values are different.

Maybe your CPU cant do 4.7GHz.... Try 4.5/4.6... My CPU uses 1.18v for 4.5GHz but for 4.6 it needs 1.23v and 1.29v for 4.7 so you see the huge voltage jumps for each 100MHz.
Also try not to OC the ram and the CPU at the same time let the ram stock and test the CPU alone. Make sure the Cooler is making good contact, and watch those temps try to keep it under 80/85ºc

Merry Christmas everyone!! biggrin.gif

@tkoreaper
After looking at your system specs, I'm afraid CyGnus may be right. Looks like you lost the silicon lottery and got a chip with a really poorly seated IHS. The only way you'd be able to achieve a stable OC in the 4.7 range is by delidding. I'm not necessarily recommending this, but it's an option if you're really wanting to push your chip. Try dialing it back and find your "sweet spot". Like he said, try a more conservative OC that's stable and go up from there. Each chip has it's own "personality" and you'll just have to see where yours is happy at.

Tooter - thanks for the reply... 1.65V. I have just put in a pair of kingston hyperX 2133 8G sticks and was able to get the recommended timings manually @ 1.6V. So far so good.

Anybody know what the Auxillary temperature reading on an AsRock E3G3 board (using HWmon64, or Open HardwareMonitor) is actually the temperature of??

What about at 4.5? My programs still crash after a little bit... any idea what the culprit could be?
