Is this not so?
Not necessarily. What does top(1) show if you add up the real and free memory? In my PowerMac7,3 I show: spdmem0 at mem0: 128MB DDR SDRAM non-parity PC3200CL3.0 spdmem1 at mem0: 128MB DDR SDRAM non-parity PC3200CL3.0 spdmem2 at mem0: 256MB DDR SDRAM non-parity PC3200CL3.0 spdmem3 at mem0: 256MB DDR SDRAM non-parity PC3200CL3.0 I show almost 750MB in top(1) which is about right. With my PowerMac11,2, I show: spdmem0 at mem0: 2GB DDR2 SDRAM non-parity PC2-4200CL4 spdmem1 at mem0: 2GB DDR2 SDRAM non-parity PC2-4200CL4 spdmem2 at mem0: 2GB DDR2 SDRAM non-parity PC2-4200CL4 spdmem3 at mem0: 2GB DDR2 SDRAM non-parity PC2-4200CL4 spdmem4 at mem0: 1GB DDR2 SDRAM non-parity PC2-4200CL5 spdmem5 at mem0: 1GB DDR2 SDRAM non-parity PC2-4200CL5 spdmem6 at mem0: 1GB DDR2 SDRAM non-parity PC2-4200CL5 spdmem7 at mem0: 1GB DDR2 SDRAM non-parity PC2-4200CL5 I think top(1) only shows a total of 2GB between real and free memory but the machine is off at the moment so I cannot verify due to the SATA issues. If top(1) shows more than 2GB, I believe more is being utilized but I could be wrong on that. Bryan
