Hi,

use ILO / ILO2, to get this information.

for example ILO:

Server Status
Memory Modules present at POST
DIMM 01 : 512 MB 400 MHz
DIMM 02 : 512 MB 400 MHz
DIMM 03 : 512 MB 400 MHz
DIMM 04 : 512 MB 400 MHz
DIMM 05 : not installed
DIMM 06 : not installed

for example ILO2:

System Information ==> memory

DIMM 1A : 1024 MB 667 MHz
DIMM 2C : not installed
DIMM 3A : 1024 MB 667 MHz
DIMM 4C : not installed
DIMM 5B : 1024 MB 667 MHz
DIMM 6D : not installed
DIMM 7B : 1024 MB 667 MHz
DIMM 8D : not installed

hi,

that's strange, normally if we are buy a server, we made a inventory check of delivered parts from invoice, them the server will be installed. ( ILO + OS + APP + monotoring )

Hmm in your case you could open the box, and look inside how match memory bank are used,

maybe snmp could be helpfull.

Hello Aamir,

Run the command
"dmidecode"

Slowly scroll down until you see something similar like:
Handle 0x1107
DMI type 17, 28 bytes.
Memory Device
Array Handle: 0x1000
Error Information Handle: Not Provided
Total Width: 72 bits
Data Width: 64 bits
Size: No Module Installed
Form Factor:
Set: 4
Locator: DIMM8
Bank Locator: Not Specified
Type:
Type Detail: Synchronous
Speed: Unknown
Manufacturer:
Serial Number:
Asset Tag:
Part Number:

Every Memory module slot of the system should be in Pairs (Set: 1, 2, 3 etc..) Therefore 2 DIMM slots should belong to a Set.

To see if there is any install RAM in the slots look at the Size. If there is a module installed, it will list the memory size.

hope this will help, thanks,
