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,
