I have a few sets of 10 gridseeds. They were advertised at 3.3 Mh/s per set. My actual hashing speed is 2.84 Mh/s, which is about 86% efficiency.
Are the new ASIC's advertised hashing speed estimated? Or have they been verified/tested as accurate speeds (e.g. 54 Mh/s for the War Machine)?
Mine were running at 360 kh/s each, are you dual mining or not using cg. I have found cgminer gave me the best results
