Hello all

I have just completed my first 10 rings x6 GPU's, but i'm having some doubts that my settings are correct:

flashed all bioses
tried to get the optimized cclock mclock some cards are stable some cards are not

Using claymore dual miner 9.8
-mclock 1925-2000 (few cards are stable with 2k)
-cclock 1150
-cvddc 850
-mvddc 850
Afterburner for fan control

doing around 26-27.5 Mh's
at the end i'm doing the following hashes, which i think they are low

Dual-mining is a bit unstable and i have even lower mhs for main eth.

Are this cards the weakest of the bunch?
If someone can lend me their experience, i would happily take any bits of advice
