Have i lost the silicon lottery? i7-3770k

was speaking to intel there and another place and intel said that cpu pll voltage should be set to auto on an ivy at 4.5-4.6 etc (although they simply wouldnt talk about overclocking obviously, lol, i tried though, lol, but the other place which i wont name said that it would sometimes get put up past 1.8v in extreme overclocking, they both said auto means it helps to keep the system stable, and at a higher voltage than auto with an extreme clock like 4.8-4.9 etc then they would usually raise it up from 1.8 to keep stability, none could offer an explantion of what it really really does though, crazy init, lol ?

Ah I made a typo I meant at above 4.5GHz not 4.2GHz.
After about 30 minutes of Prime95 or IBT and monitoring temps with RealTemp I hit 100c on some cores and both CPU's I have had have been much the same.

even 100c+ @ 4.6 is high mate, mines at 4.6 on full stress in a room thats maybe 26c approx, mines was peaking on random cores into the low 80's to low 90's, hmmm.

I am pretty sure the 3770K has a thermal protection trip switch built in, but it dont kick in until 130c as far as i hear, to me thats too high, but ive been thinking maybe intel are fooling us all into thinking the 90's are dodgy, in that case then why have a thermal trigger at 130c ???? :confused: makes ya wonder, dont it....hmmmm...:confused:

p.s
and @ bmorgan98, yes mate, intel burn test is fine mate so long as you always make sure its the most up to date version you have as they keep releasing updates, its free anyways :)

Ive been using it years now, just set it to maximum stress level, all cores and to run x10 times, and do it maybe 3 times over, thats what i do, obviously have cpuz open at same time and your tempreature program as well so that you can see everything, but dont have anything else at all running in windows background and dont use the pc at all, if you did it will blue screen for sure because of the stress its already under.;)

How come Coretemp reports the Tj max is 105c were did you get 130c?
 
105 is throttling basically the CPU if pushed to the 105C mark will throttle performance down to try to stop any damage to it. If you persist and it reaches 130C it shuts off completely. At 105C the performance would drastically fall to try to take the temps back down.

ahh i see, and therefore thats the reason its a good idea to try and keep out of the 90's then, i see i see :);)
 
@ bmorgan98,

I am taking a guess that you dont have your cpu voltage set to "offset", youve probably got it set to manual, if so, please follow this guide here >>>
http://rog.asus.com/forum/showthread.php?2162-Overclocking-Using-Offset-Mode-for-CPU-Core-Voltage

Its for the sandybridge I think but it works the same way really for the ivy bridge, you will then get your idle voltages to go very very low and therefore give you a lower idle tempreature.

As I already said, I only learned this myself the other night and it took quite a few hours of trying and trying, but eventually I got it set perfect so that my cpu voltage would only go to the top volts I wanted for my overclock under stress and then on idle the voltages just fall like a stone, works great mate, if youve not done this then you need to, honestly.

p.s
that link was from another user of the forum that helped me, so without him helping I still wouldnt have known how to do it either, its actually easier than it looks by the way.

You're right about the blue screening, I tried running IBT max stress and then decided to make the test a little more extreme by attempting to load GTA IV :) Not a good idea, it managed a few seconds, then it froze and blue screened :p I think IBT max stress is extreme enough as it is it seems, although I was able to browse the interwebs when it was on very high stress level (though it was very laggy)

I even had mines up at 4.7, no probs at all apart from hot hot hot, in the 90's, but it could still do it no probs and stable too, but as I keep saying in my posts, whats the point when a lower clocked ivy bridge 3770K will out perform an sandybridge thats clocked at a higher speed anyway (in most if not all benchmarks), keep it down a bit man, slightly cooler, slightly less volts, and still kick a higher clocked sandy up the backside, lmao ;)

(plus the other extras you get with ivy too like built in HD graphics, pci-e 3.0 compatible etc that you dont get with a sandy, its a no brainer man);)
