I have been scratching my head on this one for a week....


I have a supermicro 5014c-m8b, it has an intel P dual core 531J  3Ghz
processor with 4GB ram, the bios shows 4GB however dmesg show 3GB, I
installed Red Hat and had the same issue. If I take off 1GB from the
server the bios and dmesg match....

As per specs from Supermicro the server can take up to 8GB ram. I called
supermicro and they claim that the chipset does not support memory
remaping, and that other resources are utilized by subsystems such as
I/O and PCI Express.
