Question about memory

[sourcode]

Hi all

I'm using Proxmox VE for testing and production server for a month.
Proxmox VE is work very well, thank you dev team

But i have some problem about memory of my test server that have 4GB memory.

Test server #1
# free -m
total used free shared buffers cached
Mem: 3261 354 2907 0 16 212


Test server #2
# free -m
total used free shared buffers cached
Mem: 3937 2892 1045 0 433 1596


Why my server can't see full memory ?

Maybe some memory is reserved by the bios, or allocated by a graphics card?

server's bios show 4096 and built-in vga fixed 64mb of memory.

any idea ?
