    Hi Robert! The times I listed were for N570s and all were at the stock clock. The single 570 @ 900 has memory set at 1900. You are correct, Collatz does like fast memory so you might be able to get more out of it by increasing that a bit, but I haven't tried. Let us know if you have luck doing that.

    CC likes fast mem, but I don't like - too hot for multiGPU. This is the reason for my absence in CC.

    Has anyone played with the best settings for 580s?

    Also, does collatz use DP? Would a TITAN do better with DP set to better DP with the slower clock speed?

    These work well on the 570s and would probably work fine on the 580s, but I don't have a 580 so I might just be sucking air on my guess.

    verbose=1
    items_per_kernel=20
    kernels_per_reduction=9
    threads=8
    sleep=1
    build_options=-Werror

    No, Collatz doesn't use DP.

    I added my app_cong.xml and exe config settings to the Project App Configs thread - http://www.setiusa.us/showthread.php...1555#post71555

    It is based on what I learned (correctly or incorrectly) from this thread and the collatz forums.
