I apologize for this thread but I needed an answer quickly. I was sure I had a Vivo, so I went ahead and tried the soft mod, NO DICE! the Bios fashed ok but only up'd the default core to 520/560, only 12pipes. Now the card does not run properly. At everything stock I was able to overclock the card to 520/570, now Im lucky if I get 500/530. I've looked online and got conflicting reports as to wether I can Re-flash the card to the original bios?? If so, use ATI flash or Gigabyte. Thank You for any input!!! Call me crazy but still might try the hardmod. Thanks again, Paul
