Current Version: 2.2.3
MSI Afterburner is a RivaTuner-based utility that allows you to easily and conveniently overclock your graphics card in addition to a number of other features, including a built in OSD. With AB you can easily control your card's clocks and voltage.
Always be careful when overclocking and especially overvolting your graphics card. If you see artifacts on-screen during game play or other atypical issues you should ALWAYS back out of whatever application you're using and bring down your clocks/voltage. When overvolting it is very EASY to burn out your card. I nor HD will be held responsible if you fry your hardware.
Before getting started you will need to download the program HERE.
Enable Official Overclock
The instructions in this section established by LTMatt.
There are two ways to overclock with AMD cards (particularly 7970 models). The official way using CCC/overdrive and the unofficial way using MSI afterburner which is detailed below.
The problem with the unofficial method is that it causes some problems in terms of screen flicker, especially when switching between profiles, as well as other problems. It also affects power play, meaning cards don't always clock down as they should. The best way to overclock is with the official method. Doing it this way, you will find less problems with power play and ULPS as well as the other problems mentioned.
The problems with the official method in the past were the limits imposed by CCC. To get around that do the following:
1. Install the latest AMD drivers.
2. Install the latest version of MSI Afterburner.
3. Right click afterburner desktop shortcut.
4. Select properties and add -xcl to the target box. It should then look like this: "C:\Program Files (x86)\MSI Afterburner\MSIAfterburner.exe" -xcl
5. Click apply and run the shortcut. It will say ccc limits increased.
6. Delete -xcl, apply, and restart your pc.
7. You can now use the official overclock method without those crappy ccc limits.
8. Now you can overclock using AMD's optimal method. There are no CCC limits and you can adjust the voltage. This is SO much more stable than overclocking the Un-official way using msi afterburner.
This should remove the flicker flash problems that AMD users have been complaining about recently.
Warning: You shouldn't unlock overdrive in CCC using this method otherwise it might interfere with afterburner.
You can set everything with afterburner once you've done this: Clocks, volts, power level and fan control unless your card is locked, like the 7970m. If that's the case you can still overvolt your card by flashing the vBIOS (covered in a later tutorial).
Enable Unofficial Overclock
This is for users with AMD cards who wish to enable the unofficial overclocking mode in MSI Afterburner. It may be necessary to use this if the official overclock method for AMD above does not work for you.
First navigate to MSIAfterburner.cfg file in AB's main folder. Likely in C:\Program Files (x86)\MSI Afterburner\
You'll need to open the cfg file in notepad or wordpad. Scroll all the way to the bottom and find the following lines:
Change these to (or copy and paste the following):
UnofficialOverclockingMode = 0
You should have access now to your card's clocks, fans speeds and voltage control (if supported by your card). This version of overclocking control is not supported and can lead to bugs/glitches that you would otherwise not experience like screen tearing, instability, etc. Usually a restart will help stabilize things.
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 1
