I am going to attempt to overclock my gpu. However, I want to see if the voltage is causing the issue with an overclock I did (950/1800/2200/Stock Voltage.)
 
Anyone have any tips on doing this with MSI Afterburner, and if not Afterburner, some other program?

Are you having issues with your overclock that leads you to believe that a voltage increase will help? If you put everything back to the way it came out of the box, do these problems go away. Keep in mind the SC cards come with an overclock already in place. 
 
Try taking smaller steps to see where you actually begin to see the problem. Start maybe by an increment of 10 and see when the issues start. Then you can add a little voltage to see if it clears it up. 

Try to lower a little bit the OC and see if gets stable, if it does, then use that way, a small OC wont give you any reall performance gain.
 
If you want a more agressive OC, then after reach the limit with stock voltage, ou could increase it a little 0.01V and see if it gets stable, the up the clock again until find the next limit.
 
REMEMBER!!!! The maximum acceptable voltage is 1.1V, but most great OC out there run fine arround 1.07/1.08 so when reaching these values be carefull.
 
Also dont forget that your card will produce more heat, doing a custom fan profile would be recomended!
 
But for this card with air cooling the limt is arround 950MHz so dont think you can go much higher, at least not something that will compensate the trouble.
