Increasing Voltages & Extreme OC HD 4890 Using RivaTuner

This may not be new to some out there but at least it is for a few others and I.
I bought an MSI HD4890/1GB recently and was really excited when I found that my card could do about 980~1000mhz on the core for benchmarks. Its actual stability was around 970~980mhz
It was really cool but I wanted more.(Well, who wouldn’t?)
The thing is, the max available limit on CCC (Catalyst Control Center) was also 1000mhz.
Some days back, Guru3d.com released an overclocking article on the HD4890 over here.

They also provided the 4890 config file for Riva Tuner.

Great, so now I can use RivaTuner to adjust the limits above 1000mhz on the GPU core.
But there are are cards that don’t even hit 950mhz stable at all. We just need a slight bump in voltage to stablise that.
