Introduction

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

Founded in 1987, ECS, the long known "king of motherboards" is headquartered in Taiwan with operations in North America, Europe and the Pacific Rim. In June 2003, ECS was selected for two years in a row for Business Week Magazine's exclusive Information Technology 100 list (50th place in 2003 and 8th in 2002). In the category of Computer and peripherals, ECS is ranked the world's 12th and leading other Taiwanese based motherboard manufacturers.

ECS has built the RS400-A motherboard with cost in mind. Since Intel's chipsets are rather expensive they went with an ATI RADEON XPRESS200 chipset.



ATI's chipset allows some nice features like having PCI-Express x16 and AGP at the same time, you can also use either DDR1 or DDR2 memory. AGP Express is not really AGP, it is more two PCI slots put together in form of an AGP connector. This means it does not offer the special features of AGP like Sideband Adressing or Direct Memory Execute. Bandwith is also shared with all PCI devices on the bus, resulting in slower performance. Compatibility could be an issue, but in theory all AGP cards should be able to run in PCI mode.

This board looks like an upgrader's dream to facilitate the transition to DDR2 with PCI-Express x16.
