If you are a system builder looking for the absolute lowest power consuming PC then RAM may be something thats overlooked. Extremely low voltage RAM like the kit of HyperX we have here today can really help bring down power usage. This can be a great building block for an extremely low power PC. This also future proofs your components in a way since Intel has stated that the next generation of CPU's will use even lower voltage DDR3 than what is common today. However we will be using this RAM on an AMD based system which does not require the RAM to run at 1.65 volts or lower. This may be the case in a lot of computers since AMD makes some of the most power efficient CPU's currently available.With that in mind you may think that this RAM would run at a very low speed. However the opposite is true. This RAM can either run at 1600 MHz using an amazing 1.25 volts, or 1866 using a slightly higher 1.35 volts. Whether you sacrifice some of the power savings for raw performance is up to you, but with the capability to run 1866 MHz with a mere 1.35 volts, this RAM almost seems unbelievable. Let's take a look and see if this RAM is able to live up to the high expectations given to it.
