Hi, I have two 2GB RAMs installed in my Lenovo T400, and I generated a report using the hardinfo util which gave the following output(notice the 3056MB instead of 4GB).


Processor 2x Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
Memory 3056MB (2223MB used)
Operating System Ubuntu 10.04 LTS
User Name jean (Jean Abraham)
Date/Time Tue 10 May 2011 09:57:00 AM EDT



But, when I run
sudo dmidecode --type memory, I get the below:

# dmidecode 2.9
SMBIOS 2.4 present.
