The most challenging, and often most annoying part in overclocking your new uber graphics card is the voltage adjustment. Not everyone is technically gifted enough to apply a voltage mod to increase the GPU/Memory voltage. (Never mind bringing in the risk involved in this process.) In the past, only MSI and Abit offered us the ability to adjust the voltages with software. ATi has finally made the leap and given overclockers a reason to celebrate. In their new RADEON X1800 series they have given us the ability to modify the GPU/DDR voltages without using a voltage mod. Unfortunately, this useful feature never screamed out enough to the users like it deserved to be, until now. This step is giving a lot of respect to ATi from the overclockers. From now on you can exponentially limit your risk to the card without a voltage mod. All you need is the ATiTool or R520 Overclocking utility.
