    RAS/CAS bits mapping

      Physical address mapping to the RAS/CAS bits.

      Hi all,

      I am working on development of Memory(RAM,MCU,DIMMS) diagnostic tool for the AMD opteron processors ...My work requires the RAS/CAS bits mapping in the physical address bits.

      EX if the physical address is 32 bits out of this x bits will be allocated to Row Adress and Some for Column address ....

      These bits varies depending on the size of the DIMMS.

      Please do guide me where I can get these information from?

      Thanks in advance.

      Thank you,
