Athlon 3000G CPU Core Overclocking
CPU core overclocking is straightforward on the Athlon 3000G. There is only one relevant voltage: the CPU core voltage (“Vcore”). In order to overclock we simply set a voltage and a speed.
At stock our Athlon 3000G runs at 3.5GHz with a voltage of 1.26V. We picked a lower voltage of 1.2V as a starting point, and used Prime95 Small FFTs to test the settings. Initially these were short 10 minute runs, with longer tests used as we homed in on more stable settings.
|Speed||Vcore||Test Result||Max Temp||Core Only Power|
|Stock (3.5GHz)||Stock (1.26V)||Pass||53C||20W|
Safety is a consideration with increases in voltage like this. The Athlon 3000G is made with 14nm silicon – we think it’s probably repurposing the recent “Dali” chip for low-end laptops. This means the expected safe voltage would be up to 1.425V if the chip is kept below 75C. However, we’re conscious that heat from the CPU cores may make it harder to push the integrated graphics. We could almost certainly stabilise 4GHz on our chip with more voltage, but we decided instead to back off.
A related concern is that the CPU will get hotter in gaming loads that stress the integrated graphics. Hotter chips are normally less stable. Because of this, even though 3.95GHz seemed stable, we went with settings of 3.9GHz at 1.3V.
