Hey guys finally figured out the memory underclock on my sapphires 5830's using atiflash and RBE.. I modifed the RAM setting under "Clock Info 02" to 300, then went into additional features and set the upper limit GPU setting to 1000. Currently stable running clock speed at 985 and memory at 300 . Now when I go to clock speed 1000 I get cards going to offline.. Do I need to voltage levels to run the clock at max speed. speed, if so do I change it also under "Clock Info 02"??
When I modified my Sapphire 5830's I only went to the clocks tab and then modified both the GPU and Memory clocks under the boot info.
