With CGMiner, try diablo's kernel. Most if not all of my 7xxx cards are pegged at 99% usage. I'm using CCC 12.3 as well. 12.4 really messed up mining for me.
Thanks, cgminer is alot better compared to guiminer.
cgminer, 12.2 pre beta driver (reccomended by cgminer author)
-I 9 -k poclbm --auto-fan --gpu-engine 1100-1180 --auto-gpu --gpu-vddc 0.88 --gpu-memdiff -150
gets me 702Mhash/card on 7970
poclbm currently gets me best performance
How do I know which kernel is running?
I guess that means that youre 7970 gpu core is between 1100-1180mhz and the memory is 150mhz less so 950-1030mhz?
I'm now 1125/1050 on the 7970 and it gives 660mhash, the 7950 is 1100/1250 and 575mhash.
I would like to overclock more the core but it is capped at 1125 for 7970 and 1100 for 7950 how do I unlock that in cgminer or windows 7 because I have watercooling?
