I know im just jumping in here but i thought id add some interesting things Ive noticed with my x10. There are times when I initally turn it on and it just loads the miner that the hash rate will for each board spikes up to 20GH/s for 60 GH/s total. This has happened a few times. Ill try to get a screeen shot the next time I can but if thats true these machines are very powerful and they do really underclock them.
