Clock Frequency: 4.6 GHz, Multiplier: 23x, CPU Voltage: 1.5 V
This is where we drew the line for our overclocking experiments. Although the system was still stable using both water and air cooling, the processor's voltage was already higher than the manufacturer's recommendation. On top of that, system power consumption spiked above 400 W, which absolutely wasn't what we were looking for when we started testing for efficiency.
