Overclocking

Overclocking on air

As always we tried to overclock the processor. It certainly is doable but we're not sure if it is desired; proper liquid cooling is a must with this processor series. We got the processor stable at 5200 MHz all-core. 5300 MHz would boot fine, however created too many stability issues. At that point, we'd pass 1.5 Volts on the CPU. The heat production is significant. Realistically I'd say, leave tweaking for what it is as the defaults of these processors are already really close towards these performance regions. 


5100

Above: 5100 MHz all core yields 380W power consumption (system / GPU inactive)

5200

Above: 5200 MHz all core yields 410W power consumption (system / GPU inactive)

5300

Above: 5300 MHz boots fine, but under load is unstable, with further tweaking at micro-managed settings we'd likely get there. We did not want to push voltage any higher.
