DDR-Chipsets for Socket 462 Compared: The ALi Magik 1, the AMD 760 and the VIA Apollo KT266 all offer DDR support. However, the AMD 760 works with DDR-SDRAM memory only, while the other candidates can optionally run with SDRAM also.

Chipset Structure

The Northbridge of the ALi Magik 1 contains the DDR-SDRAM interface.
