I have the same exact card(brand: mine is a HIS).I suggest leaving memory clocks alone unless you're running at 1080p or above.So in theory you should be able to get at least to 960 with gpu clock and maybe 1000 with voltage set to 1.200.
I've tried with 3 cards and all run at 960/1300 with no problems with no voltage tweaks.
BE very careful not to over do it.
