Radeon X800 Non-Pro/X800 XL/X850 Voltmods

Conclusion

Whether you're doing the Pencil Vmod or the VR Vmod I can not emphasize the importance of taking your time as well as not getting caught up in the "just a little more" syndrome. Given the different circumstances, your overclock will vary depending upon a multitude of factors. Set yourself a stopping point and test your card by playing some intense graphic games. The forums here at techPowerUp! are filled with people who will not hesitate to help by answering a question. You can use ATITool or Systool to set and test your OC. Remember to take your time and above all be safe.
