    Optimization of the 7970 and 570 (and 460)

    Go to the collatz message boards and go to number crunching. Look at the first post something like optimization for solo collatz 4.07. Use it! It cut 1400 seconds off my 7970 times and a couple of hundred off of my 570 and 460 times.

    Actually, that's a good thing. It means Jon is back and is working on the validator issue. When it's back up, do check out the optimation sticky. It's pretty easy and either works well or doesn't do anything at all...like for my 430s.

    That thread is a mile long. What are the best settings to use for a 7970?

    According to Zydor's response to I need some educatin here... ---> http://boinc.thesonntags.com/collatz...9&postid=17082

    His settings are as follows

    verbose=1
    items_per_kernel=18
    kernels_per_reduction=7
    threads=8
    sleep=1
    build_options=-Werror

    For Zydor's complete system setup see Message 17007: Solo_Collatz Useage ---> http://boinc.thesonntags.com/collatz...9&postid=17007

    Edit: For some reason the links above only work correctly when you are logged into the Collatz forum...

    On #2 and #3 I use 22 and 9 respectively. I've also got my 7970s oced to 1125. Wus complete in 570 seconds.

    So I had my 2nd 7970 on the bench putting on a new cooler. Just installed it and the optimizations had no positive effect. With or without the optimization it was only showing about 50% usage. I took out all the optimzation and just installed an app_config.xml using 0.5 cpu and 0.5 gpu (2 wus at a time.) I'm back up to 98 - 99% usage and it completes 2 in 30 minutes or 15 minutes/wu. A figure I can live with.

    Both GPUs in the same system?

    Edit: Anyone have good results with GTX 460 & 570 cards?

    Nope, but they are both AMD cpus.

    Single 570 system - Before 1540 seconds ---> After Optimization 1263 seconds @850 1159 seconds @ 900
    Dual 570 system - Before 1933 seconds ----> After Optimization 1393 seconds @ 850 (These are averages over the 2 gpus over 40 wus)

    Edit:
    I can't really give you good times on the 460 because of a heat issue (fubar cooler) I have to decrease volts to 900 and clock to 600 to keep it below 90c, but here goes:
    460 @ 600 clock speed, memory 1800 ---> 4622 seconds (way to long)
    460@ 625 clock speed, memory @ 1800 and optimized ----> 2818 seconds
    Nothing else changed besides the clock speed and even being downclocked it decreased times by 1800 seconds, give it 1500 for the slightly higher clock and it's still worth doing.

    N570 is my favorite NVs. How high memory? I remember CC liked the high memory.
