I've been noticing that most people have not been able to hit the prized 3.0 GHz with their Brisbanes on air, which is what most reviews reported as the stable overclock during reviews last year, I believe. I'm just trying 2.9 GHz with 1.4 V now that it's fairly cold here.
make sure you get a G2 revision, not G1..
this is a 5000+ Black edition
Got a fan over those memory sticks? No? Well get to it before you kill them
Is not that hard if you get one BE-2xxx series...very easy to reach the 3GHz mark
3ghz no problem here with rev. G1..... 24+ hour prime stable.. thermalright ultra-90 w/ low speed 92mm fan.
ozzimark is right, though. 5000+ black edition is definitely the way to go for overclocking consistency.
all the later batch brisbanes I've played with have been happy with 3Ghz.
A 4800+ @ stock 1.30v even.
Brisbane 4000+ , 0732 , G1
Just 2.9GHz @1.42v prime stable , I can run 3dmark06 with 3.1Ghz v1.55

Shmaa you have one great chip there. A 3600 X2 doing 3 ghz on air easly

I can't, see my sig. Not sure whether it is my board or the CPU which is the limiting factor but I am leaning more towards the board...

Drop the multiplier to 5-6 and try again.Originally Posted by roadie
Then that means something is wrong on my end. Could it be the 1T timing that I'm using? Should I use 2T instead?
YES, 1T timing will hold you back, I'm suprised you got as far as you did.
I can hit 3g+ easy if the temps are low enough. I run 2.8-2.9 as my 24/7 clocks, but can ran 3.0 rock stable if ambient stays at or below 70F, but above that it gets a bit flaky.

Brisbane X2 4000+ w/ a Biostar TA690G checking in. OC'd stable to 2887 MHz; can reach up to 3055 MHz but not stable in S&M so I don't really trust it there. Using custom liquid cooling (black ice stealth GT 120mm radiator, Koolance CPU-330 block, GPU block, XSPC X2O reservoir/pump combo, 1/4" ID tubing) and it runs nice and cool. Can't give exact figures due to Brisbane's jacked up on-die temp sensor but it rarely passes 50c from my estimation. Performed decently on the stock air cooler, actually, but I didn't do any prolonged stress testing there.

1T will definitely hold back a memory overclock. cpu speed shouldn't change with command rate, unless the memory is the limiting factor of an overclock
