OK!
Here is what we all been waiting for: First Brisbane overclocking scores on the Interent:

In the BIOS of this Foxconn mobo Vcore is set to 1.5V.
Corsair Dominator working on 1033 MHz@2.45V
This is the max OC on this Air cooling. I was hoping for 3.2 GHz, and went all the way to 1.7 V in the BIOS, but could not make it in to Windows. As a matter of fact anything beyond this frequency was not stable!
Not bad for Air Colling ;) .
Now how low you can go on voltage @ 3100MHz?
The other thing I'm interested in is mem bandwidth. Is it same as for RevF or is it better?
So far :woot: and:clap: for good work!

Like I wrote, CPU is under BOX FX74 cooler.
If that temp is correct, you should be able to push it even higher. Too bad it maxes out at 3.1ghz.
Kudos to the man who published the first OCing results for Brisbane on the internet!!!:woot:
And for the good air cooling,early Brisbane made a good show :D ,3.1Ghz air cooled is great!
And here are some benchmarks under 3.1 GHz!

those are looking pretty nice! Could it not handle the 13x multi?
I remember the times when it was smarter to buy Newcastle instead Winchester ‘cos the newest CPU, made in the newest tech, did not clocked like its predecessor.Quote:

The most important thing about Brisbane is that is cooler (someone who’s building fanless machine could care about this), and that AMD can build much more of them making the space for even more price clashes.
Me personally expect that thanx to Brisbane, AMD will dramatically improve their positions on the notebook market.
It could, but I wanted to push Dominator more ;) It works flawlessly in all the multi+HTT combinations that are resulting in 3.1 GHzQuote:

Is your barrier at 3100 mhz an exact thing? Someone said that software issues could possibly be limiting the oc's? You should try around 10 - 50 mhz more and see if anything in there you can get stable. If you cant get anything stable at all or even remotely stable, wouldnt that be evidence of a bug somewhere other than the chip? Or maybe a limiter somewhere in the system? I have never really experienced a cpu that would clock right up to a number and wouldnt do anything higher at least for a few minutes!
Waiting for an update :) hopefully it hasn't hit a for sure wall yet.
In my book this has the same importance like overclocking:
Lowest stable voltage for the stock frequency (2.6 GHz):

I’m off to bed
That's pretty sick but I won't even look at it until you get the DMM out and check the actual voltages. For all we know it could be 1.4v even though CPUz says otherwise.Quote:

damnit he left. He should be required to stay till we're satisfied :p don't want to anger the man with the treasure though or he won't share.
i wasnt really expecting much of a clock for clock performance gain, if any. Mainly interested in the lower voltage/overclocking potential.Quote:

4 Ghz on chilly water might be asking for too much...
not bad..Quote:

If I get around to it, I'll run a 3.1c2d 8mb tomorrow morning.
Core will demolish it.
