The server is a dedicated server, i am managing it remotely via SSH.
Because of the steps of memtest86:
* 1) Insert blank floppy
* 2) dd if=/usr/local/share/memtest86/floppy.bin of=/dev/fd0
* 3) Boot the floppy
I couldn't use it, but i did a test with memtester (sysutils/memtest)
and got a lot of errors: 
The memory looks like dead..

bsd# memtest 256MB
