There is supposed to be issues with the P5K seeing 2gb when 3 or more is installed, but i haven't heard about it only seeing 1gb.|
Download the latest bios from asus and flash your board (asus have a handy windows install) if that doesn't work see if the ram is broken, by trying them individually.
edit: it may also be the slot on the board itself. You could try the ram in slots 1 and 2. They won't be paired tho.
