Hi all,

I've recently installed Deepin 15.5 (64bit version) on my machine.

All is working great except the OS is only detecting 3.3gb of 8gb (2 x 4gb sticks) RAM I have installed.


I've tried running the following commands:

# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.

The BIOS also detects 8gb rather than 3.3gb

Any ideas how to get Deepin to detect  / use the full amount of RAM installed on the system?

Thanks in advance,
