There are two ways to determine this:

1. Use dmesg(1M) to read the memory information from the kernel message

buffer:

Near the bottom of the output of dmesg should be something similar to

the following:

Memory Information:

physical page size = 4096 bytes, logical page size = 4096 bytes

Physical: 65536 Kbytes, lockable: 39496 Kbytes, available: 48264 Kbytes

The Physical: section gives you the total number of kilobytes of

physical ram.

Do not be alarmed if the memory information is not in the dmesg output.

The system error message buffer is of small, finite size. If the memory

information cannot be found there then go to step 2.

2. Use adb(1) to read the memory information from the running

kernel/memory:

[Remember the numbers returned must be multiplied by 4]

For 10.X execute:

echo "physmem /D" | adb /stand/vmunix /dev/kmem

This should return:

physmem:

physmem: 16384

For 11.X 32 bit execute:

echo "phys_mem_pages /D" | adb /stand/vmunix /dev/kmem

This should return:

phys_mem_pages:

phys_mem_pages: 106496

For 11.X 64 bit execute:

echo "phys_mem_pages/D" | adb64 -k /stand/vmunix /dev/mem

This should return:

phys_mem_pages:

phys_mem_pages: 523264

hi,

glance -> and "m" will do it!
I don't forget this one and hence is my first source for checking memory on the system.

Hi,

Another way to find out the physical memory is to run mstm information tool on it.

Within mstm, highlight "Memory", then from the menubar, select "Tools", "Information", followed by "Run".

Detailed information on your physical memory will be shown including:
1) Configurable memory
2) Page size of memory
3) Memory interleaving status
4) Memory board inventory
5) Memory error log summary (eg. single-bit errors)
6) Page Deallocation Table (PDT)

Hope this helps. Regards.
