Need Ram info

[zatan]

Hi
Is there a way to find out ram info on each slot?

Anyway to know if there is any slot available to put more ram in? My client is remote so I cannot see by myself

Number Of Devices: 2

Shows you the number installed dims together with the spec of the motherboard you should be able to work it out...

on Dual CPU systems you might get multible Memory arrays...

Your filled DIMM slots will show up as elvis showed above; empty slots will show something like this:

root@truenas[~]# dmidecode -t memory # dmidecode 3.2 # SMBIOS entry point at 0x7f0c7000 Found SMBIOS entry point in EFI, reading table from /dev/mem. SMBIOS 3.0 present.

This partial example shows that there are 4 DIMM slots: A1, A2, B1 & B2. DIMMA1 is filled with a 16GB module, but DIMMA2 is empty.

Hope that helps.
