Download MSI Afterburner Via

http://event.msi.com/vga/afterburner/download.htm

Once downloaded go into the Msi Afterburner CFG and change the EULA to I confirm... and overclocking mode to 1

* Set UnofficialOverclockingEULA field to the following text: I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
* Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path

They changed the way to bypass the limit so type this into your CFG file in Afterburner so you need to type in that sentence in the EULA to bypass the 900MHz limit

If you're referring to the CCC OC limit, that can easily be bypassed with third party overclocking applications.

Afterburner, Trixx, your pick.

Open the MSI Afterburner config file (MSIAfterburner.cfg) using Notepad (located in your Afterburner install folder), change the following string "UnofficialOverclockingMode=0" to:

Quote:
UnofficialOverclockingMode=1
Then, enter the following as a statement confirming the limit bypass next to "UnofficialOverclockingEULA":
