Comment 0 for bug 1321938

Hi,

My motherboard died and Gigabyte had to replace it with a newer model (specifically, a GA-970A-UD3 replacing a GA-870A-UD3). After installing the replacement motherboard, the system boot and operated just fine. I did notice after a few days, however, that "free" and cat /proc/meminfo only show only 8gb of RAM:

root@s3:~# cat /proc/meminfo
MemTotal: 8155016 kB
MemFree: 253264 kB
...

However, lshw DOES see all 12gb:

root@s3:~# lshw | grep -m 1 -A 50 "*-memory"

Any one have any ideas on what I need to do to get Ubuntu to see all 12gb?

Thanks.
