I am running Debian testing and 'uname -a' shows: 3.13-1-amd64 #1 SMP Debian 3.13.7-1 (2014-03-25) x86_64 GNU/Linux
And 'dpkg --print-architecture' shows: amd64 I have 4X2GB of ram installed and BIOS confirms this at 8192. However, Linux sees only about 4. 'dmesg' shows: Memory: 3334308K/3406004K available And /proc/meminfo: MemTotal: 3349972 kB This is the output from 'dmidecode' <SNIP> Memory Array Mapped Address Starting Address: 0x00000000000 Ending Address: 0x001FFFFFFFF Range Size: 8 GB Physical Array Handle: 0x0024 Partition Width: 1 Handle 0x002A, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Physical Device Handle: 0x0025 Memory Array Mapped Address Handle: 0x0029 Partition Row Position: 1 Handle 0x002B, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00080000000 Ending Address: 0x000FFFFFFFF Range Size: 2 GB Physical Device Handle: 0x0026 Memory Array Mapped Address Handle: 0x0029 Partition Row Position: 1 Handle 0x002C, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00100000000 Ending Address: 0x0017FFFFFFF Range Size: 2 GB Physical Device Handle: 0x0027 Memory Array Mapped Address Handle: 0x0029 Partition Row Position: 1 Handle 0x002D, DMI type 20, 19 bytes Memory Device Mapped Address Starting Address: 0x00180000000 Ending Address: 0x001FFFFFFFF Range Size: 2 GB Physical Device Handle: 0x0028 Memory Array Mapped Address Handle: 0x0029 Partition Row Position: 1 </SNIP> Where to go from here?
