Hi @ all! It may have come to your mind that there is a new method around enabling you to change your video card's voltages using RivaTuner. For reference, look here or here. The funny thing about this is that I'm already aware of this for a few months now. Problem is that this method needs the card be equipped with a Volterra VT11xx voltage controller chip which is why I wasn't able to make it work with my 3870. So I thought this isn't working at all. The new research showed that the method works with cards that actually have a VT11xx, such as the 4870 or 4870X2 (reference design, at least). Long story short: I experimentally implemented this feature into RBE as well. The feature will be enabled just for 4870 and 4870X2 cards for now. You will find the feature at the lower left corner of the clocks settings tab, near the voltage table. There's a button that will open a new window where you can enter the new voltages for the several registers. Please also adjust the voltages in the power play settings to the new values as well. If you have a 4870 or 4870X2, are experienced at flashing video cards and the RivaTuner method works for you, I'd appreciate if you'd download the new RBE beta version and tested if the method applied using RBE works for you as well. Please post any experience or bug reports concerning this new feature in this thread. However, please be sure to have your boot disk/USB stick or whatever ready as well as your PCI card before trying this. This RBE version is not labelled beta, even though it is. If there are no bug reports but users reporting this works, RBE v1.19 will go official just the way it is. Okay, here's to the brave: Download the beta and let the testing begin!
