It's not the frequency that kills cards, it's the volts. If you're stable with 1250Mhz, then sure, go ahead and use it, but I doubt that would be stable. 1000Mhz is very respectable for an OC on the 6990. The After burner developer says they limited 1.125V max for the 6990 so see what you can get with that. Some apps let you do 1.3V but that's likely to kill the card unless you have DICE or LN2.

You have to enable unofficial overclocking.

Quote:
To enable the unofficial overclocking in this version it is necessary to edit the MSIAfterburner.cfg file located in the installation directory of AfterBurner (typically Program Files (x86) MSI Afterburner):


You need to alter the following:
  • Seek UnofficialOverclockingEULA field and add 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

To make ANY settings kept after upgrade edit MSIAfterburner.cfg stored into .\\Profiles folder instead of MSIAfterburner.cfg stored into the root application folder. The .CFG file stored into the root is a template with default setting for .CFG file located into profiles folder, and the template is always overwritten on new version installation.
Leave powerplay active.
