[SOLVED] 3GB RAM problem on x86_64

Anyone knows why I have the 3GB problem on arch x86_64?

In more detail:
upgraded my office PC, got a core2quad, 4GB RAM (2x2GB), installed arch x86_64 (the 09.02 iso).
Free only shows 3.2GB of memory, dmidecode correctly shows 2x2GB.

Everything I've found online regarding this is for 32bit versions. Why do I have this problem on x86_64? More importantly, how do I solve it?
Thanks

Nvm, it seems the unbuntu guys are ahead, got a very fast answer.

If anyone ever has this issue, I had to enable memory remapping in the bios.
