prtdiag & DIMM size question. - comp.unix.solaris

I'm comparing a Sun Fire v215 & a Sun Fire v245. The prtdiag on the v245 looks like it has 2 x 1GB DIMMs, but I didn't think they came that way from the factory. Doesn't the "Bank Table" show the physical size of the DIMMS? What does the "Memory Module Groups" show? Because the v245 shows 4 entries there, which would make sense if they were 512MB DIMMs. Thanks in advance. ============================ Memory Configuration ============================ Segment Table: ----------------------------------------------------------------------- Base Address Size Interleave Factor Contains ----------------------------------------------------------------------- 0x200000000 1GB 1 BankIDs 0 0x1200000000 1GB 1 BankIDs 16 Bank Table: ----------------------------------------------------------- Physical Location ID ControllerID GroupID Size Interleave Way ----------------------------------------------------------- 0 0 1 1GB 0 16 1 1 1GB 0 Memory Module Groups: -------------------------------------------------- ControllerID GroupID Labels Status -------------------------------------------------- 0 1 MB/P0/B1/D0 okay 0 1 MB/P0/B1/D1 okay 1 1 MB/P1/B1/D0 okay 1 1 MB/P1/B1/D1 okay

But bank I think refers to the memory(chip) banks, not physical banks. Below is a machine with 16GB, but CPU1 has different memory vendors on CPU1.
