5850 Voltage Control

Hi chaps, I've got an Asus 5850 with the voltage tweak feature, this is running on a fresh install of W7 64.

I know of only 2 apps which allow for voltage control of this card, both of which casue me problems.

With SmartDoctor I have full control over voltages and clocks but for some reason all of my fave games crash out when entering a new game!!
If I completely remove SmartDoctor, gamerOSD and Asus's catalyst and then install the latest ATI catalyst (10.3) all my games work as they should again.

I then tried MSI AfterBurner, but annoying when its installed as soon as I execute the app it blue screens my system!!

So as it stands I cant use Smartdoctor as it wont let any of my games run without crashing and I cant use Afterburner simply because it blue screens my system.

Are there any other 3rd party apps that can do the same job as the above ones, or even better are there any solution out there for the above issues I have with either app?

I would appreciate any help.

Cheers :)
