The following table lists all of the chipsets that are currently available for the AMD Socket 462 platform and support DDR SDRAM. Older models with SDRAM support (such as VIA KT133A) are not taken into consideration here, because for a while now, boards with such chips have no longer been produced and offered on the market.
