Introduction

I would like to thank ECS for supplying the tested motherboard.

The ECS A770M-A is one of the first ECS motherboards that supports the new AM2+ Socket. This means that it is an optimum habitat for the new Phenom processors. However, you can also use all previous generation Athlon64 models with this motherboard. The board also uses AMD's new RX780 chipset which uses HyperTransport 3 and includes support for PCI-Express Generation 2. This motherboard has been designed for the value segment but still tries to give you all the features of more expensive motherboards like Gigabit Ethernet and high quality 8 channel audio.
