DDR has become the memory platform of choice for both the Pentium IV and Duron/Athlon, representing a changing of the guard from SDRAM. A few months back, AMD introduced the world's first Socket-A DDR platform - the AMD760, introduced to bring DDR-SDRAM to the Athlon processor and continue to do so until a third party chipset manufacturer supplies a viable DDR solution. AMD took similar steps with the AMD750 chipset while introducing the Athlon processors to the world. However, the transition this time didn't occur as smoothly or as quickly as planned, hence the profusion of AMD760-based motherboards. With greater overall performance than the VIA KT266, this chipset is still desired by many.
One manufacturer to offer a AMD760-based solution is DFI, with the AK76-SN. More accurately, we should say AMD761-based. Due to the AMD761 North Bridge being linked to the AMD766 South Bridge via the PCI bus, all manufacturers (including DFI) opted to use the VIA 686B South Bridge due to its lower price. While many would consider this practice to be taboo, there are only 2 incompatibilities as identified by AMD; the inability to support the South Bridge's IOAPIC; potential data corruption when switching into the ACPI S3 power management state (Suspend to RAM) in systems that use registered DDR DIMMs. The first is easily alleviated by adding a pull-up resistor, but there is no solution for the second.
That said, let's get acquainted with the AK76-SN :
