The launch of Phenom II processor family breathed new life into AMD CPUs overclocking. These processors based on 45nm cores boast pretty good overclocking potential that can be uncovered by raising the frequencies over their nominal values. Our earlier tests showed that these processors can work at up to 3.7-3.8GHz frequencies with air-cooling employed. However, those conclusions were made for the 900 series processors based on fully-functional Deneb cores. Now we got our hands on a Phenom II X4 810 with a smaller L3 cache. Moreover, it is made in Socket AM3 form-factor.
To study the overclocking potential of the new processor we used new Gigabyte MA790FXT-UD5P Socket AM3 mainboard. With the help of this board we will also check how overclocking-friendly the new Socket AM3 platform is overall. We used Scythe Mugen cooler with Noctua NF-P12 fan for our CPU.
We managed to achieve the best result by raising the processor Vcore from the nominal 1.3V to 1.525V. In this case our CPU overclocked to 3.64GHz, which is quite comparable with the results obtained on other Phenom II processors that we tested before.
Note that since Phenom II X4 810 processor doesn’t belong to the Black Edition series and doesn’t have an unlocked multiplier, we overclocked it by raising the base clock generator frequency. Namely, we get 3.64GHz we had to increase the clock generator frequency to 280MHz and our Socket AM3 mainboard coped with it perfectly fine. In other words, CPUs overclock in Socket AM3 systems in exactly the same way they do in Socket AM2+ systems that is why you can refer to our overclocking guide for additional details.
As for Phenom II X4 810, the 40% frequency boost may become a good argument in favor of AMD platform. Especially, since Intel Core 2 Quad Q8200 processors priced comparably can often go only as far as 3.4GHz. Therefore, a system built on Phenom II X4 810 processor may become a pretty attractive choice for overclocking fans.
