Hi , I'm mining scrypt jane N Factor =14
6970 speed 4.7 khs (core/mem 900/400)
7950 speed 4.2 khs (core/mem 1000/400)
Who can explain why 6970 run faster than 7950?
Post your configs for each - SC N=14 is memory intensive, so the faster GPU doesn't always win. Also, you may be having hardware errors you didn't mention (or notice)
