Mining flags for a 7990?

[LESLIEx317537]

I'm running my 7990 with no flags and getting about 1044 MH/sec.
Is there a better flag that will allow more MH's?  Thanks in advance.

what program are you using? The 7990 has a low GPU clock speed. My dual 7970 GHz edition run at 1100 MHz and use up less juice combined, with just as many shaders, and costed a penny less.

I get 1325 average with diablominer with dual 7970 GHz editions.

I use -v 1 -w 256
