Voltage tweaking is done exactly the same way as upping the Core/memory speeds. If MSI AfterBurner did not already do this for you. Now go back into the settings page reselect the first GPU (or other) then set that core speed accordingly. I set the GPU core speed to 820MHz, and the memory to 950MHz. Pretty straight forward here, locate the Memory/Core clock sliders and then move them to the right until we reached our target clock speed, or you can use your arrow keys to fine tune the clock speed. Like so, now we can adjust the frequency. Notice the Core Voltage is at 1064mV? we need to reset this to 3D state just like we did on the first GPU core. Which brings us back to the primary page we just left.
In the first drop down menu you will see your video card listed here, since a 4870X2 video card has 2 physical cores I need to switch to the GPU 2 core. Pay attention to the General Tab, we are not going to mess with the other tabs just yet. After the GPU 1 has been reset, locate the Settings Button located towards the bottom right hand side of the main window.Īfter clicking on that button, we will see a page with a few tabs. Notice now the Core Voltage is now at 1262mV. This is what you should have after resetting the default settings. Notice the core voltage is at 1064mV (1.064 volts) The voltage shown here is the default 2D speed, we need to reset MSI Afterburner to properly set the 3D speed of the 4870X2 (this will be GPU specific). The 4870X2 video card runs at a 2D speed while in windows and ramps up to 3D speed while running a game. If you have multiple GPU’s I will show you how to flip from one GPU to the next during this portion of the guide.
Your video card will be listed in the upper center window in green lettering as well as the driver version you are using. After double clicking the icon you should have a window just like mine. The icon should be placed on your desktop. OverclockingĪfter you get MSI Afterburner downloaded and installed, we need to execute it. This guide will be broken up into sub sections,Overclocking and Fan control to simplify things a bit.
After you get this program installed lets get on with the How To Guide. Unlike RivaTuner MSI Afterburner is a lot simpler to use and navigate.īefore we start off with this article we first need to download and install MSI Afterburner, this program can be found HERE. This guide Is based on how to use MSI Afterburner on our video cards. On October First of 2009, MSI has released a RivaTuner based Overclocking utility, that will allow us to overclock our video cards. Here is a guide that shows you how to overclock your video cards with MSI Afterburner.
