After format speed goes down 50% on HD 7970
#2
you cannot always get full performance out of plus. to quote atom, "dude! you have to give it work!" speeds can vary greatly depending on what exactly you are doing.

that said, i think you were a bit mistaken about the speed. with plus and single md5 hash, you can only get ~ 6 G/s max out of a 7970. you can get ~ 8 G/s out of lite, though.

try the following and see if you don't get full performance. should be around 6 G/s.
Code:
--force -n 160 --gpu-loops 1024 11111111111111111111111111111111 -a 3 ?a?a?a?a?a?a?a?a
