Much more interesting is the kernel messages on boot, e.g. on my laptop it looks like this: BIOS-provided physical RAM map: BIOS-e820: 000000000009fc00 @ 0000000000000000 (usable) BIOS-e820: 0000000000000400 @ 000000000009fc00 (reserved) BIOS-e820: 000000000000c000 @ 00000000000c0000 (reserved) BIOS-e820: 0000000007ef0000 @ 0000000000100000 (usable) BIOS-e820: 0000000000010000 @ 0000000007ff0000 (ACPI data) BIOS-e820: 0000000000060000 @ 00000000100a0000 (reserved) BIOS-e820: 0000000000200000 @ 00000000ffe00000 (reserved) On node 0 totalpages: 32752 zone(0): 4096 pages. zone(1): 28656 pages. zone(2): 0 pages.

Copyright SGI, All Rights Reserved Memory: 125696k/131008k available (1311k kernel code, 4924k reserved, 949k data, 184k init, 0k highm em) as you can see, the above tells you exactly how many pages you have in each zone and the total number of usable pages. But even that is not relevant to your question. What is relevant is the number after the first "/" in the "Memory:" line and also the BIOS-e820 map, of course. Also, on 6.4G machine you should definitely use 64G i.e. PAE support and so if not all memory is detected, please report to this list. People like David Parsons will probably be interested in your configuration...
