    I have 2 x 6850 in CrossFireX

    Using CCC only gets me an 850Ghz core OC

    I know these cards can give 940/950 Stock Voltage and 1Ghz at a push with higher voltages of 1.181v

    I read a review that someone got the 6870 specs with the 6870 voltages

    And yes this is true with a single card, damn I can get 1Ghz with a single card

    But with CrossFireX its a crash as soon as I press apply, even though they are still in 2D mode

    -------------

    Ok so I checked default voltage and it looks like 1.148v for most of them with stock core 775mhz

    So with that in mind I set my clocks 940/1100 @ 1.148v

    I have CCC Over drive turned on, and GPUz says they are both still at 775mhz / 1000

    WTF is going on, I had no issues with my 5770s in Xfire and AB

    Even Sapphire TRIXX crashes it


    Anyone with 2 x 6850 managing to OC them past CCC 850 limit ?


    And is there a way to hack CCC to allow a higher Core clock ?

    I tried 2.1.0 - same thing, just tried the beat 2.2.0, same thing

    If I set the voltage to default

    Seems to be working so far thank you, best score Ive had yet

    950/1100 @1.56v

    ;)


    Can't get a full 3DMark11 score yet as my 4Ghz seems to be unstable

    Im guessing its the CPU as Furmark runs fine


    EDIT - 1.52v was the stable voltage for my 4Ghz - very high I know, but fook it

    53c highest load temp under torture test P95
