Patent ID: 7301847

Claim:
A method for adapting a main board having a DDR2 connector and lacking an onboard DDR1 connector for use with DDR1 comprising: outputting a voltage suitable for DDR2 to a DDR2 connector via an output end of a voltage transducer, whereby the main board being joined to DDR2; connecting the DDR2 connector to an end of an adapter; connecting another end of the adapter to a DDR1 connector; and connecting an input end of the voltage transducer with a ground end of the adapter during the main board being joined to the DDR1 connector such that the output end of the voltage transducer outputs a voltage suitable for DDR1 to the DDR1 connector, whereby the main board is configured to be selectively associated with DDR2 or DDR1 by the presence or absence of the adapter.
