    How can I OC further than 860 on clock settings on 5870m?
    I've seen people talk about going to 900, but my max is 860..
    I want to push it even further, because it never goes over 65 celsius when playing with 860/1075

    Why can't you go further? It crashes or the program doesn't allow you to?

    Not every card overclocks the same. What program you use for OC ?

    I believe the MSI cards use 1.05v as the stock voltage. The cards you're seeing around 900 are using 1.15v.

    I cant push it to 900, because it won't let me. The settings are maxed at 860, so i cant pull the lever thingy beyond 860.

    AMD OVERDRIVE.
    MSI afterburner knows the card is "Ati AMD 5800 Series" but it doesn't even see the drivers
    My drivers are the newest one from ati, the one with the new ccc

    You need to flash your GPU to 1.15V to even think about 900.

    Use MSI afterburner and edit the configs to allow unofficial overclocking, it'll allow more range.

    I use MSI afterburner and you only need to edit a setting on one of the ini files, to allow greater overclock.

    Im at 1.05v and 900/1035 clocks only work for benches, because in gaming it tends to crash (driver crash, because ir self recovers) but its a pain to play like that.

    I use anything from 860 to 880 and 1025 memory to play games, and higher OC only for benches.

    Core clocks help more in general because the memory bandwidth of the GPU is decent. Memory will help if you are playing at high resolutions or adding AA etc. I have found that 1600x900 gives the best performance/res in newer games.

    However, I think in general, our HD5870m for GX660 only overclock well in core, not much for memory so don't get any high hopes.

    Still a small 20mhz increment in memory helps even if just a bit.
