ECS A790GXM-AD3 Motherboard

The Socket AM3 Black Series Gets Better

ECS continues with their Black Series of motherboards with the introduction of the ECS A790GXM-AD3 motherboard. The Black series boards that we have dealt with have seemed to have a quality build with great features and they are offered at a very reasonable price. Today’s market seems to find nearly everyone searching for a bargain, so this new motherboard from ECS may be just the hot deal you have been looking for... or is it? That is what we intend to find out as we look at the AM3, 790GX based motherboard.


The A790GXM-AD3 Black Series motherboard uses the AMD 790GX chipset, so it fully supports all of the Phenom and Phenom II processors on the market today. In addition, the ECS A790GXM-AD3 comes with the feature of dual channel memory architecture that supports DDR3 1333MHz memory up to the capacity of 32GB which is capable to provide faster data throughput for memory-intensive applications. To meet hardcore overclockers’ requirements, the latest exclusive BIOS utility, M.I.B. II, is included to provide various detailed tweaking options. Paired with AMD SB750 south bridge controller supporting the function of ACC (Advanced Clock Calibration), ECS A790GXM-AD3 allows users to push the overall system performance to another higher scale. It also means that you you are trying to 'unlock' a triple core AMD Phenom II processor and make it a quad core this board should be able to give it a shot. The board also features a five phase power design with a massive heat sink to help keep things from overheating. The board of course also features AMD CrossFire technology for true multi-GPU gaming performance and six SATA II 3.0GB/s ports that support advanced RAID configurations like RAID 5 and RAID 10. Let’s take a closer look at all the specs:
