    Also can anybody educate me if it better to get a higher latency # with higher ddr speed.

    For example; which would be faster on our computer:
    Cas Latency 7 DDR3 1066 or Cas Latency 9 DDR3 1333???

    Sorry; signed confused...

    Cas 9 1333 memory usually will default in our systems too cas 7. This really depends on the SPD so it is not a garenty what it will revert too.

    As far as Apple rated memory I can't say. Maybe someone else ahs tried out thoise specific sticks................

    You shoul be fine as another user posed they worked on his p7805. Now our systems supposedly do not like some sticks that use high density chips. Now I've heard others using high density have no issue so this could be a SPD issue especially since our boards seem to like to force command rate at 1T......
