SIN even notes this below it though "You should try to fall under these voltage ranges or slightly above to stabilize your OC, these are the recommended voltages per frequency, however the CPU I used is very good it seems, so you might need more voltage than I did."
I never noticed that comment before, but that explains it!

i figured out multiquote!..lol

yea, thats why most of the time i say , its a startpoint/reference,
you might need more or less vcore,
i will emphasize it more next time i use the chart smile.gif

i started with the 1.25V vcore at 4.5ghz from the chart, was close enough, needed 1.235 to make it stable later on..

and this chart, the 1.52V vcore "intel rec. max" that puzzled me long time, where peeps said it wasnt true,

On Air/Water: Intel Rec. Max is Intel’s absolute maximum rating for the Ivy Bridge lineup, many of the numbers provided are identical to those of Sandy Bridge, however while vcore should be lower because of a better processing technology (22nm vs 32nm) it is max 1.52v here because of the SVID max. When overclocking on air the only two voltages you should need to touch on an Ivy Bridge setup are the Vcore (which you increase) and the CPU PLL( which can be decreased to help temperatures). You should not proceed to just apply the maximum voltage for the vcore, vtt, or system agent as you will heavily increase the temperature so much so that the CPU will throttle and can be damaged. Also if you start off with a higher temperature it is very hard to test stability, as you will probably be more unstable than if you used a lower VCore.

thats the number from intels datasheet,

its the VID range, where others say vcore and vid has nothing to do with eachother,
but i believe sin before others

i noticed when using this chart on the last page post

it also uses the VID as highest vcore..

1.2V @ 4.2ghz priming since about 10:00 last night and I checked it this morning before I came to work and its still going. hopefully it hasn't BSOD on me cause by the time I get out of work it will have been under Prime Blend test for 24hrs tongue.gif

if it still runs when youre back from work,
24H prime is 99.9% stable smile.gif

I'm starting to think that 1.2v @ 4.2GHz is more the norm nowadays.
after days and days of tweaking that's (about) what I'm running.
temps are still in low-mid 50's on load so that's where it is (winter time = colder temps)..
curious to see what 4.4GHz voltage brings, will do sooner or later, this is not my 'gaming' unit so I'm in no rush.

Are you delidded malmental? 4.2GHz @ 1.2v could do 50Cs if ambeient temps are real low if not delidded, but that would still be low temps. Using RealTemp for temps?

He stress tests with aida64 so the temps aren't as high as someone who stresses with prime or ibt tongue.gif

ATM I have 4.2 at 1.20V. 10 minutes of prime and it was at 62C with an ambient of around 23C I guess. smile.gif

my ambient is low (room temp), my case temp on my BitFenix fan controller show 20C..

You'll never run hot on a 4.2ghz Ivy lol
No need to fight over temps at such a lowly oc wink.gif
