So stepped things up dual mining SHA and Scypt to 800Mhz, and I am getting 6.4GH/s and 340Mh/s avg per gridseed, they get mildly warm but nothing that i would be concerned about.
Anyone try dual mining under windows at 850Mhz yet, I dont want to push them too far when mining sha alongside scrypt as the sha asics can get fairly warm.
850 is about the safe limit for these in dual mode, anything above that might be too hot for the chip.
OK so I tried dual mining at 850mhz on both sha and scrypt and I start to get a ton of red noonce on the scrypt, If I keep scrypt at 850 and reduce Sha to 800 or less the red noonce go away. So I currently have Sha at 750 ant scrypt at 850. I am getting 6GH/s sha and 360kh/s Scrypt. I feel this works best for me.
