Radeon X800 Pro/XT/XT PE Voltmods
Using Variable ResistorsThis section I decided will be brief due to time restraints and less descriptive. Understanding the same warnings as posted previously in the begining of the article. You should read the "Introduction" and "Before you Begin" sections.
There are several VR How-Tos on the web. Each one has a different tweak, it's one of those more than one way to skin a cat deals. But we'll just do the basic VR to resistor solder.
Tools and SuppliesTo do these mods you should aready have soldering skills and should be using a low wattage iron. I also assumed that you would be using a magnifying glass and until now didn't think to mention it.
- Digital Multimeter (have to have one)
- Glue Gun (to set VR in place)
- Variable Resistors: 1x 10k Ohm, 1x 250k Ohm, 2x 20k Ohm
Next read the "Getting Started" section to get your default voltage. This can be important to get an idea of where your voltage will be when you crank up the card. You can still use the same table as the pencil mod. What I mean by that is if the default Ohm reading of the VGPU is at 420 and you add the 10k VR, then given that a 10k VR will give you around .04v which in turn equals 15 Ohms then after adding the VR your new Ohm reading should be around 405 Ohms.
