Alright so recently I ordered two antminer S7's. One of them works totally fine at the projected 4.73 TH. On the other hand, This other S7 got to full hashrate and quickly drops. The issue I'm seeing is that the one of the boards falls to start and hash and sometimes makes another board go with it on not hashing. There is still all o's across the asic status but the board never goes above 16 on the temp. I'm not sure what this is considering that there is no x's over the chips and none are missing. Firmware is up to date.
Here is a link to a picture of what it looks like
