    Anyone have any suggestions on whats a good overclock for the 285m's. I have been searching for an example for the past hour only to find constant comparison of the card to the 5870 and no overclock examples.

    Download Nvidia System Tools or EVGA Precision and play with the frequencies.
    To make sure you have stable clocks run some benchmarks.
    Have fun.

    Something like this:
    GeForce GTX 280M videocard

    700/1230 is the highest I can see for the 280m, since it's pretty much the same as a 285m you can try those clocks.
    Maybe 650/1100 if you don't overvolt (or maybe even lower depending on voltage).

    I thought I read something back when I had SLI 260m's that just raising each settting is not always going to show positive results. I heard somewhere that they work best if the numbers stay in a certain ratio. Is this true? Also since the 285 is basically an overclocked 280, from what I've heard will I be able to get much of an overclock out of the 285's without adding more voltage.

    EVGA Precision will let you link the Core and Shader Clks(thus keeping the ratio between them while one is raised/lowered) don't remember about NvST,sorry.
    Usually more juice = increased stability.
    You should also know that different cards DON'T overclock the same way.One may reach the sky as the other will fly with the birds(hope i make sense :p).
    The 285Ms are also a bit overvolted compared to the 280M.
    -play with the numbers -> bench.
    the clocks Moral_Hazard posted are a good start,try them on first,see if you're stable,if you are go higher if you want.
    cheers

    There is no such thing as a ''good overclock'' because every single individual GTX 285M card will be different. One overclock on a GTX 285m could damage another. The only way to be safe is to slowly experiment yourself.
