BIOS Setting s show

Total Memory     : 4096 MB with 8 MB Shared Memory
                           : Dual - Channel Memory Mode

DDRII1                 : 2048 MB/266 MHz (DDRII533)
DDRII2                 : 2048 MB/266 MHz (DDRII533)

There are no setting to limit RAM in BIOS :-(

real memory  = 3078291456 (2935 MB)
Physical memory chunk(s):
0x00001000 - 0x0009efff, 647168 bytes (158 pages)
0x0102d000 - 0xb779ffff, 3061264384 bytes (747379 pages)
avail memory = 2884808704 (2751 MB)

any idea what could be the trouble?

I was testing the amd64 port for a new backup server.
I guess i will go back to the x86 port since more than 3 GB RAm is not
recognized any how  :-(

thanks
