CentOS 6 x64 not using all of my RAM.

Bios see's all of my RAM and so does DMIDECODE, however the kernel won't use more than 3gb.
Code:
[slimg00dy@localhost ~]$ sudo dmidecode -t memory

Also the speed mentioned in bios is 1600, not 1333.
This is what the kernel see's.

Are you running a 64-bit build?

Could be an onboard GPU with 1Gb of shared memory set? A common cause for perceived RAM disappearance.

I have seen that, however that's for 32 bit systems to support more than 4gb of RAM. I've got a 64bit system that shouldn't require a PAE.

you're right if your system is 64 bit you don't use it

Keep in mind that the CPU I'm using is an AMD bulldozer cpu, do any of you think that the kernel is too old to support this cpu?

I think the problem is in the BIOS or motherboard.

I think your 64-bit kernel will use all the ram that the BIOS enables.

That sure doesn't look like the whole dmesg. I think you dropped some. There is normally a BIOS memory map section early in dmesg showing what ram the BIOS has enabled for the OS.

you're right if your system is 64 bit you don't use it
