Cisco ISR 4431 Router DRAM Memory

[gerry.murray]

Looking to find the total (useable) DRAM memory on Cisco ISR 4431 router. Is it 8Gb or 16 Gb ?

Thanks, 

cisco ISR4431/K9 (1RU) processor with 7792789K/6147K bytes of memory.   < < < <   8 Gb
8 Gigabit Ethernet interfaces
32768K bytes of non-volatile configuration memory.
16777216K bytes of physical memory.        < < < < <    or 16  Gb
29929471K bytes of flash memory at bootflash:.

16777216K bytes of physical memory. < < < < < or 16 Gb -  is the correct one i believe.

Thanks for the response. Not many routers show these two lines for DRAM memory, any idea what each one is for. Why two different values?

16 GB it´s the correct.

Modern Cisco IOS runs in the background as a separate process (IOSd) on Linux OS. Thus, you see only a half of DRAM allocated for IOSd environment and total physical memory of entire system. You can issue `show mem` to find how much available memory in IOSd at the moment. And `show platform software status control-processor brief` command to find current memory usage of entire system. (yeap, it's a crap, no more simple cli :\)
