Today Legit Reviews takes the same processor we overvolted to reach an amazing 3.1GHz thanks to water cooling and go the other direction. We undervolt the AMD A64 X2 4200+ AM2 processor and try to find the lowest possible voltage the processor can run still stable at with the hopes of lowering power consumption and system temperatures.
"Undervolting proved susscessful as we were able to reduced temperatures and lower the total power consumption on our test platform. Our testing showed that we were able to shave off 28W at full load, so by undervolting we can expect to save up to $34 a year by reducing the utility bill. It almost makes you wonder why more people aren't doing this!..."
