One of mine started acting up in a similar manner(about half normal hashrate poolside but looked good in the UI) recently and a reflash of the firmware fixed it.  Maybe give that a try?  Guessing it won't help your bad board though.  If issues continue you may want to remove it entirely and see if the others shape up.

Try to downclock your S2 a little. I know its running a stock speeds but the X's might go away if you downclock it a little.

Yes try and flash the firmware but also get the cooling down.   67 is pretty warm, mine were all around 57 and under with no problems.  You can always move the board to a different slot and see if it's the board or a problem with the backplane or lack of power.  (those stock psu's are pushed to their max.)

Try re-seating all of your boards. Also move the suspect board to a different slot and see if the problem follows it.
