How do I change my gpu voltage on my hd4870's using rbe? The highest voltage option I can choose is 1.26v. I really want to overclock them higher than the 800mhz ccc max. Also what is the best way to up my ccc limit using rbe? Thanks for ur help in advance!
 
Anybody? Is this possible?
 
I believe you have to volt mod it. Try googling a volt mod guide for your video card.
 
use ati tray tools or gpu tool, you can override the overdrive limit with it.
 
Take a read here for some ways of adjusting your GPU voltage.

Some different ways there for altering voltages, try and see which will work for your card.
 
Be very careful either way you do it, bump it one notch at a time and watch your temps. Also you might not be able to do it, you I believe need the Voltarra WRM cards to be able to software adjust your voltage, and I don't think any of the 512MB 4870's ever had that.
 
Well ill give that link a once over and see what can be done. I have the his 4870 with the aftermarket cooling and the non reference power color 4870 temps so far are 58c max
