The 1860Mhz speed should be its speed out of the box. Why are you trying to overclock it?

Hi drewlrocks,

Here's the catch.. In vga card, memory speed is defined as FSB x 2, thus, if the default speed is 1860MHz, the actual FSB is 1860/2 = 930fsb..

If you use either ATiTools (or vendor software) to overclock your vga core and memory, the speed that you set in your memory speed is 1100fsb x 2 = 2200MHz.. and you actually set your memory speed to your vga card at 2.2GHz!
