All RAM not recognized by 64-bit install

do you have an option to run a memtest86? edit: (regardless of everything)

while, I recommend this to your attention as well:

Hmm, not much there.

You might try booting in verbose mode. Create the file /boot/loader.conf.local then add to it: boot_verbose="YES".

That will give you a lot more output at boot. It may show you some ACPI errors or similar responsible for this.

Since the OS can't possibly be 32-bit your next culprit is the BIOS.

FreeBSD shows you what hardware is there (8GB) and then what has been made available to the OS (~3GB).

Check for things like memory allocated to onboard video, any kind of memory management that might be geared toward a 32-bit OS, and other things of that nature.

@jimp How could the video memory card allocate that much ram?

jimp

Ask the BIOS. I've seen onboard "gaming" video cards that would happily claim multiple GB of RAM if given permission in the BIOS.

@hoopin4you Hi, did you ever solve this issue?

I've just install a 64bit pfsense v2.5.2 and pfsense is only using 3.3gb of RAM.

BIOS and pfsense logs both show 8gb.

Real = 8192MB
Available = 3317MB

How did you get around this?

What hardware are you installing on? Some early 64bit systems had some interesting BIOS 'quirks'.

I never figured it out, and since then, I am now using a Cisco router.

It was an HP Pavilion 64-bit tower. I know the full 8GB was showing available when I had Windows installed, and the BIOS showed the same thing.

Mmm, well I would definitely try booting verbose to check the ACPI errors if you're seeing this as I said previously. There's a good chance the BIOS is passing some values to FreeBSD that Windows never sees because most manufacturers don't care about anything else.
