    Crossfiring and OCing my HD 5770 Vapor-Xs is like shoving portable heater in a mini-fridge (tried it!).

    Can anyone recommend me a case fan of pure cooling awesomeness?

    The Scythe sflex's 110CFM's are great case fans. 2000 RPM's I believe.

    I see Buddie has 2 5870's so I decided to clock this 5970 up to his stock setting and just fell shy of his Heaven mark score..

    I used redline just to bump the mem voltage **(not sure if I even needed to but I did)** and Afterburner for the rest...mem VCCD's topped out @ 56c

    Using MSI Afterburner I find OR need some advice from the fine ppl in TPU for a cooling curve.

    Can someone give me a fan curve for a 5970 so it keeps the components cool but the fan at a reasonable Db level?

    Thanks.

    Why it say only 1024MB GDDR5 for your 5900? Or is it counting the dual Gpu's as 2 single units. Jus curious :)

    It counts two single units with 1gb of ram allocated to each individually. :toast:

    crossfire and SLI do not add ram. 2GB dual GPU card = 1GB per GPU = 1GB usable ram.


    I think if you check my post history, i say this at least once a week...

    Thanks, and yes I remember you saying something like this many times :D These graphics guys need to fix this problem. How about if the graphics card has 4GB GDDR5 will 2GB only be used for games :confused:

    no there isnt. some people have said there is on 5K cards, but there is NO difference between one and two bridges in my testing.

    Yes but it can get quite unstable if you lack cooling.
    Ask the super, he require 2 bridges for 2 of his HD 4870's or Crossfire won't work right.

    then i would say one of his bridges doesnt work.

    i tested on P35 (16x/4x) and x48 (16x/16x) and had zero difference. ran for months with one, and a few with two on each mobo.
