You have a very similar setup to me, and I see youre at 4ghz on the same Mb too! Nice man.

As above, 1.45V or under should be fine if you wanting to reach 4Ghz or lil more, JUST make sure you have proper cooling.thumb.gif

I'm running 4.15GHz at 1.425 volts and the NB is at 3100 with the CPU-NB at 1.325 volts - If you're aiming for 4Ghz or even a bit over, you shouldn't need anywhere near 1.475vCore - let alone the 1.5 to 1.55 that others have mentioned above.
The quote below is from the link below.
http://www.overclock.net/t/777378/official-gappos-little-deneb-thuban-overclocking-guide-with-too-many-smileys
"CPU VOLTAGES
We've a tried and tested limit of 1.55vcore for Deneb based phenom II's and Athlon II's. It's a safe limit and you don't see much scaling past that so this is you
Thubans are a different story. We've heard from reliable sources that past 1.475 is the danger zone. Much past that and heat is going to become an issue anyway. If your on a Thuban on ambient then this is you."

Until "reliable sources" has been exposed, I take most of what I read with a grain of salt. From what I've seen in the clubs and from my own testing, there aren't many setting that require much more than 1.5Vs to remain stable.

In a nutshell, the added voltage from 1.5V and above rarely makes the processor work any better. Other factors, such as the IMC or motherboard, appear to be the limiting factor. In 99% of the decent motherboards out there, the 960T dies out around 4.2ghz on air, regardless of voltage.

So you're doubting sources but basically agreeing that there's not a point in going that high anyway?

Unless you have quantified data proving that it is in fact safe to run a Thuban over 1.475 volts, I don't really think you should discredit the information and links provided..

It's widely agreed that pushing a Thuban past that point (1.475) is not only very useless, but dancing with the devil. A Thuban isn't going to run under 55C on air with any cooler at 1.5V anyway, and they all get unstable around 55C so I'm not sure what you're getting at.

I guess some people just post for the sake of calling somebody wrong even when others agree and back up their statements with fairly reputable sources.

I'm going to lean on the side of El Gappo - the "benchmarks editor" for overclock.net - as being the correct guy to listen to.

I will say that if you're just going for a max OC to run some benchmarks on, and you have the money to replace a burnt up processor should it happen, then yes - 1.5 volts would be relatively safe.

Woot! go the EVO! May they serve us well biggrin.gif

btw running a thuban at 4GHz on air wont require a heck of a lot of voltage anyway. I have mine set in bios at 1.375 and it goes up to 1.39 under load. rarely goes above 40C with a hyper 212+ in push-pull.

Then again each chip is unique yours may or may not require extra voltage

I pushed mine all the way to 1.56v, any more than that and I would trigger the motherboards CPU overvoltage protect. For 24/7 use however you should keep the voltage as low as possible, for this processor I'd say that, unless you have some serious cooling, you should keep it at around 1,40-1,45V.

I've run 4200 (300x14) at 1.5v for a while now and the chip hasn't seemed to suffer any damage from it, though- posts here indicate that Thuban =/= Deneb, and that the maximum safe rated voltage for Thuban is 1.475v with its more-recent Low-K SOI process.

YMMV, but this is coming from a 1075T user.
