Sapphire 6850 ati overdrive GPU clock won't increase

Hi i jsut got my new gaming rig up and running

I did the ati overdrive software and it finished the values say
GPU clock 840 Mhz
Memory clock 1190 mhz.

at the bottom it says

current values
Gpu clock 300mhz and memory clock 1190Mhz


Shouldn't my gpu be at 840mhz.

300 seems pretty low unless i'm not understanding a multiplyer or something

    ATI and nvidia cards throttle down in 2D mode, and looking at the CCC pannel is 2D mode :)

    Play any 3D video game in windowed mode and than check speeds, it should be your OCed settings :)
  2. My buddy just told me i screwed myself going intel chipset with ati card.

    Is this true? i've never read or heard of anything to support this with empirical data.

    Type "5850 benchmark review" and almost every single benchmark you will find will be done on ain intel chip. Your friend is wrong.
  4. And for further proof. Check this out: http://www.xbitlabs.com/articles/video/display/radeon-hd5870-cpu-scaling_4.html#sect3

    The intel setup is faster with ATI cards.

    ^agree 100% true
  6. are those settings pretty good for the hd 6850?

    I have to say i'm quite disappointed in the wow performance, I was recomended about half high half good. I can run it on high at 1920 x 1080 with 45min fps mostly 60 though.

    I was kind of expecting ultra :(

    My build is

    i5 760 at 3.0ghz
    8gb ddr3 1600mhz
    hd 6850
    750w modular thx PS
    asus p7p55d-e pro mobo

    People always underestimate what WoW demands.

    However, you should be able to use mostly Ultra settings, you just have to turn down the shadows a notch or 2. That's what really hurts the performance. But don't expect more than low to mid 30's in Dalaran.
