Well, changing frequency to default does not fix the new firmware problem. Woke up this morning and 3 of the 6 S3+'s are running at under 50Gh/s. Hope they fix this problem quickly.
after several test I still had the same problem so I reinstalled the firmware antMiner_S320140811.bin and for the moment it is 4:40
