Note: The first socket 754 Sempron had the 64 bits extensions deactivated, but from July 2005 on AMD has been launching socket 754 Sempron models with the 64-bit instructions activated. The socket 754 Sempron models listed on the chart below can be found with the 64-bit instructions either deactivated or activated. The models with 64-bit extensions enabled have the letters "BX" as the two last letters printed on the CPU package.
