The EATX motherboard is an abbreviation for the extended ATX, primarily for rackmount server systems. It is typically used on servers that are not capable on dual processors and standard ATX motherboards, with 12x13 inches (305mmx330 mm) in size. Eatx the upper part of the motherboard has the same fixed screw position as ATX and is used for high-performance workstations or servers, EATX is generally very rare in the market because it is designed for workstations specifically. ETX motherboard size is larger, generally require a special EATX chassis, and ATX Obvious difference is the size of the location of the installation hole. The EATX motherboard features a similar but powerful, but also a few inches larger than the standard motherboard size for ATX motherboards.
Eatx motherboards, commonly known as EATX server boards, support more than two CPUs, because the most important thing for servers and workstation boards is high reliability and stability, followed by high performance. Because most servers have to meet the full workload requirements of 24 hours a day, 7 days a week. Because of the large amount of data processing of server and workstation, it is necessary to adopt multi CPU parallel processing structure, that is, to install 2, 4 and 8 CPUs in a server and workstation. For servers, multiprocessor can be used for high load and high speed applications such as database processing, and for workstations, Multiprocessor systems can be used in three-dimensional graphics production and animation file encoding, such as the single processor can not achieve high processing speed applications. To accommodate long, high-volume high-speed data processing tasks, in memory, servers, workstation boards can support up to more than 10 GB or even dozens of GB of memory capacity, and most support ECC memory to improve reliability.
