What make it different ?
1) arch==> i386 limit to 4G (dmesg) and spdmem show 8G , Bios show 8G
2) arch==> amd64 memory show correct figure 8G (dmeag, spdmem and bios)
1 & 2 use the same machine with different arch.
So can I use the i5 core at i386 arch to use the correct size of memory (i.e
8G) and how to make it work .
Thanks
clarence

i386 showed the correct amount of memory *it could use*.
