Except for very high quality server boxes don't trust the dmidecode data
for the RAM. Get the motherboard/system name from dmidecode then look it
up manually

Can you tell anything about it ? I have IBM x-series 206 server. Here
is the dmidecode information. Is SDRAM or DDRAM installed on it. It
would be great if you can tell me where to look.
