Also showing temps at 0 and the wrong number of chips?

Ah that will be the rare 144 chip version of the S7 Sir...  Smiley

There is no rare 144 chip version, there is only a  162 chip version and a 135 chip version.  This is not an image of an S7.  This is the single section of an S5+ which had has 144 chips on it (obviously the one with the controller card on it which can be moved). 


I think you missed the  Smiley on my comment...

So you are suggesting that the OP has the centre section from an S5+ and not an S7? Got to say that seems very unlikely and I do not think the S5+ has 600MHz available?

Rich

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  Smiley, 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.

Well I just checked and with the firmware that is on the controller card that is my S5+ it only goes to 500 Mhz.  Which leads me to my next question, could an S7 controller card work on an S5+ card.  I sent the OP a PM to see if he got this straight from bitmain or 2nd hand.  I have a funny feeling about this but kind want to leave it at that until I get more information.  If he tells me 2nd hand, I am 99% certain I know who it is.
