The Overclocking Factor
What's a Black Edition processor without showing off some of its overclocking capability? With the first Phenom II X4 940 Black Edition, we managed to ratchet it up to about 3.8GHz. Now with the newer Phenom II X4 955 Black Edition (thought still using the same stepping), we got it running at a maximum of 3.91GHz with standard air cooling. That's pretty good according to AMD where they document 4GHz is about the maximum to be expected out of air cooling (but extreme cooling tactics can see it soaring to as high as 6GHz).
The Phenom II X4 955 Black Edition managed an overclock of up to 3.91GHz with just air cooling. |
While both the Phenom II X4 955 and 940 processors overclock easily, they require much higher voltage to keep up their high clocks - about 1.6 volts in our case. The higher voltage and clock speeds do ratchet up power consumption quite badly, but that's usually the unfortunate side-effect if you're really keen on overclocking. What about the actual performance gain? Not as much as we were hoping for, but you be the judge of that if it's worthwhile:-
