Well I am actually running a center piece of an S5+ right now in my farm so that is how I know on the chip count.  Yes, I did miss the  , I thought you might be referring to the the 135 chip unit that bitmain is putting out now(sorry about that).  They put out 135 chip units in batch 6 as well batch 8 which has not shipped yet.  I can tell you one thing, the image that the OP shared is not that of an S7 card.  When I get to my office here in a couple hours I will look at the frequency options to see if 600 is available.  What I do know is that if he was have issues with chips not working then they would simply be x'd out but I do not believe that they would completely disappear.  If he had a 135 chip S7 you would see 45 chips on each line, and one 162 you would see 54.  Like I said, 48 chips is not an S7 board.
