Overclocking

I'd be a fool not to test Albatron's 1200MHz front side bus 'compatibility', since it's emblazoned so lovingly on the front of the box. I'll not beat around the bush.



Ignore CPU-Z reading the 3.3V rail instead of Vcore. That's the HEXUS 3.2ES doing 12 x 300 at 1.65V, using the Albatron's +0.1V setting. However, running such high front side bus speeds would regularly cause the board to randomly reboot. Testing (thanks James) shows that it's tied to the chipset not getting enough juice, something that an increase in Vagp can fix. Pushing that to 1.6V in the BIOS introduced some extra stability, but it was never 100%.

Indeed, dropping to the 8X fixed multi mode let me run up around the 320MHz front side bus frequency mark (the CPU doesn't like doing 3.8GHz on air, at any voltage) with the aforementioned limited stability, but nothing was ever stable enough to let me run off much of our benchmark suite.

I'm not confident a BIOS update with more voltage resolution and range will help either, it's related to the way the Vddq is derived from Vagp it seems. In other words, the board isn't wired up optimally. Some voltmod trickery might result in more stability with the review sample, and indeed retail versions might be better too, but 300MHz with 100% stability wasn't obtainable. Still, the CPU-Z shot is nice to show off with eh?
