Hi
Your 7970 should be giving you a MIN of 700 Mhash each.
I have 4 differant cards only one is a 7970 but even my 7870 is over 400 mhash.
Things that help :
Underclock your Memory on the card.
use AMD APP 2.5 (2.7 only nets me 560-580 mhash)
I use cgminer and with a 6870 as main (monitor hocked up) I set the (I) intensity to 7 but for the 7970 in that rig it has an Intensity if 16 and nets me 715 mhash. this is running 24/7. Both cards in that rig are running at 66 - 68c with Fan % at 60 - 68 %.
Keep testing you will get better Mhash.
you should have a min of 1300 - 1400 Mhash.
