No.
You would need 5/8" Type X on both sides, screws spacing as required, sealant around the edges, continuity taking priority over any other walls intersecting with it, etc., to be a fire rated 'fire wall' or 'fire partition'.
Simply installing 5/8" Type X on one side does not, to anything I've seen so far, make it a "fire rated wall".
Thus, to answer Matt's question below, no, a fire rated door is not required (of course, there may be a local code which requires a fire rated door, which would be a 20 minute rated door).
Wayne,
Does that apply to two story houses with living space above the attic, or to all dwelling units, including one story ones?
There are additional requirements I did not state above for when there is living space above the garage.
