Thread: AMD 890GX ECS A890GXM motherboard chepset

The AMD 890GX chipset is the successor to the AMD 790GX and is therefore a very flexible solution for a wide audience. For home is the chipset with a graphics unit equipped for everyday use, but players can increase the 3D performance with one or two graphics cards.

Come two graphics cards to use, PEG-16 Lanes of the North Bridge will be distributed equally among them. The North Bridge provides six additional PCI-Express 2.0 lanes for additional devices or slots, and ECS has used it four lanes for a third graphics card. Apart from the graphics core, AMD 790GX and 890GX are very similar.
From the North Bridge to the processor performs a Hyper Transport 3.0 link with up to 20.6 GB / s, while the South Bridge with a maximum of 2.0 GB / s per Alink Express is coupled III. To this end, AMD uses four PCI-Express 2.0 lanes. In contrast to previous chipsets the SB850 also now offers two PCI Express 2.0 lanes to connect additional devices.

The highlight of the SB850 Southbridge is undoubtedly the six SATA ports of the third generation, which has a bandwidth of up to 6 Gb / s work. They support RAID 0, RAID 1, RAID 0 +1 and RAID 5 and JBOD and AHCI. Even one PATA channel is still offered, ECS A890GXM-A when this has not however been implemented. Furthermore, there are now 14 instead of 12 USB ports, but this match is still in version 2.0. At a minimum, USB 3.0 can be easily upgraded to AMD, because AMD's chipsets provide a bandwidth of 500 MB / s PCI Express 2.0 lane and direction, while Intel's H55 and H57 to only 250 MB / s to come.
