Obviously, I missed something... but I'm quite sure a CPU can't operate at 0.00v.




This further proves my point. 0.0 is obviously outside the specified range for normal operation considering a CPU can't even operate at 0.0. So why would you put a non-operable value and then a normal operable value after it..?

And Intel have had these chips longer than you, OverclockersUK have had these chips longer than you (please check their forums wherein Gibbo has had an engineering sample and pre-releases for a few months now) Places like Bit-Tech and HardOCP have had the chips longer than you and funnily enough they all recommend nothing higher than 1.38v. So, yeah, sorry if I take official sources as more reliable than some guy on the internet.



As above.
I take Asus as an official source.

Edit. Different thread from him mentions it, need to find the link again.

And Again I post from ASUS:

K series overclocking and voltage range recommendations

Quick Note regarding Voltage Scaling – Internal binning of both D1 and D2 parts we discovered consistent voltage scaling patterns.
1.For K series parts, the stock voltage supplied will allow for consistent overclocking generally up to a multiplier of 43x. There is potential for the multi to be raised to 44x depending on the load induced. This default voltage range be approx 1.240 to 1.260 under load.
2.Increased range between 44 to 47x multipliers will generally require a voltage range between 1.30 to 1.375V with an LLC recommended setting of high to ultra high.
3.Increasing the range between 48 to 50x multiplier will generally require a voltage range between 1.40 to 1.500 with a LLC recommended setting of ultra high.
4.Increased range between 50 to 52 (52 generally considered peak max multiplier except for rare 54x parts) will generally require a CPU voltage range between 1.515 to 1.535V with LLC at Ultra High and potential fine adjustments to the CPU skew range.

Overall a key item to note is the best voltage to oc scaling range potential for the turbo multiplier is 1.400 to 1.425 vcore. Using this voltage range with an LLC recommendation of ultra high will generally provide the best scaling potential with proper load temperatures*. We have generally found exceeding this voltage will not provide additional scaling or will increase load temperatures to a high level with synthetic load applications ( like Prime, Linx, OCCT ). Should you use more realistic loading testing (our recommendation is a combination of AIDA64 stress test, PC Mark Vantage) then temperatures under will be considerably under the max TDP rating.

*cooling recommendation and test performed with CoolerMaster Hyper 212+ with Single Fan, this is the minimum recommendation for multis above 46x. For 50+ multis we recommend a dual fan configuration with this cooler or improved cooling.
K series overclocking benefits from non CPU Voltage based adjustments ( UEFI values for power management , Cstates, PCH etc )

Most of people who run at 1.52v on Sandy Bridge are still okay since we have heard of no one degrading.
Yeah, for a chip that's been out since mid-january just about 3 months is totally enough time to judge if those voltages are safe.

I ran a Core2Quad Q8200 at 1.45v for a long time, then it died and wouldn't post until I seriously under clocked it. However, if I had run under 1.3625, the intel spec, then I don't think my chip would have died. Fortunately, OverclockerUK don't ask how you killed the chip and even if you tell them they don't refuse RMA. That's their policy, others don't have such a generous policy.




Eitherway, no matter what you guys think or say, running over 1.38v is officially set to ruin your CPU. You may get lucky and have a very good chip that performs perfectly on those voltages, or you may get unlucky and have one that dies around those voltages.

The point I want to make is that we tell anyone asking the safe voltage that it is 1.38v. No harm at all in saying "well, it's 1.38v, but I've been running 1.42v no problem 24/7 for months now" No problem with that at all. But let's juust be clear. Intel and a host of reputable hardware sites say 1.38v is the safe limit and therefore that is the safe limit for ALL chips whilst understanding that it's perfectly possible to exceed that and be safe.

No its not early. We are just about there where people are starting to degrade. So far I have heard NOTHING from those who run at 1.52v about degrading. I have also heard nothing from those who had ES samples.

Overclockers UK is not official. Unless it is from Intel, it is not official. It is second hand information from one retailers particular chip. Every CPU operates differently as stated in the data sheet.

Let me guess, overclockers UK designed and manufactured these chips?

Sorry dude but voltage kinda has to do with this. Most chips can't do 5ghz with less than 1.47v let alone 5.5ghz. He's kinda saying your voltage is unsafe.

Thats not his call in this thread. Especially when its called a SUICIDE run.
