My home server has a SuperMicro X7SBi board. Currently, I have 4GB ECC RAM (4x 1GB) installed. According to the spec page on SuperMicro's site, the board takes unbuffered RAM. A friend has a large stack of 2GB Fully-Buffered ECC RAM sticks he's throwing out, so I'm wondering if I could fit some in this board to double the capacity?
I've had a test CentOS KVM host running for about a week now with 3 CentOS guests. There's 12GB physical RAM with about 7.5GB actually allocated to VMs. These VMs aren't even being used yet as the server's still in the testing stage but I've noticed that swap usage had been climbing over the last 24-48 hours.
I have just discovered an inconsistancy in my new server setup. When I issue the free -m command the output states that I have 1993 total memory available when I know for a fact that this machine has 6GB installed. The kernel agrees with this number but dmidecode does not. I am posting the output of the commands to make my problem clearer.
