all thanks for the discussion
old.....
Wonder if a bad S4+ hashboard could be replaced with an S4.
They both use the same chips, just a different amount on the board.
Anyone think this would work?

Hey guys just bought an s4+ that was used. trying to figure out an issue with it before asking for a partial refund. Currently one of the boards, does not raise in temperature. and the unit is underhashing. but the chips show as ooooo in the chain. any ideas?
EDIT:
they show as o in the chain, until about 10 minutes in then all but one switch to x.
sometimes when the s4+ is turned on chain 2 shows 27 asics instead of 51.
And there is no orange light on the board like the other 3.
faulty board?

faulty board?
Does anyone here know the exact voltage that these chips operate at?
I know the voltage is fixed and can't be changed but what is the exact operating voltage for each ASIC?

from my research they use the same chip (BM1382) in both the s4 and s4+ and the specs are as follows
Chip specs: BM1382
Process Node: 28nm
Package Type: FCQFN-56
Packaged Chip Size: 8mm x 8mm
Number of Cores: 63
Core Voltage: 0.75 V
Core Frequency: 250 MHz
Hash Rate: 15.75 GH/s
Power Consumption: 0.59 J/GH (chip level, and it can be lower to 0.40J/GH by lowering the core voltage)

I hope that helps
I am new to bit mining and I have been having a problem getting my miner to connect to my router via Ethernet in order to find the miners IP address and I have already gone through quite a few guides and forums to try to diagnose the problem and fix it. However all have failed to fix or find the problem and it appears to me that the problem is with in the miner. A blue light on the beaglebone lights up, but when I connect the ethernet cable to port neither the yellow or green light come, which makes me think that there is problem with the beaglebone. Any suggestion on what the problem is and how to fix it?

Never mind, figured it out myself.
Just need to edit cgminer.conf

Anyone know how to restore overclocking to the S4+?
Thank you very much for your interest , but I only want the solution to the problem of the 2 cards that do not work
Dealing with Bitmain has always been excellent but think about spending more time sending undermined me not to my liking.

You need to tell details still. Is this something the miner has always done?
Or is it new for it to do? Or a new miner for you completly?
I'm asking as breaking those bolts is not normal. And trying to understand timeline.

Also you might show pictures of the "weld screws"
Are you saying you recently bought it you said "The s4 + Bitmain buy direct , but I get hit all the bases and holding up cards because loose bolts were broken". If those needed welded it would take one heck of a hit.
I'm confused if it's something you have had or a new miner to you?
These s4 + I buy direct from Bitmain is more , I give eight coupons of S7 in this forum here .
The fault was the safest shipping company .
I did not think they sold these in a while on main site. If you truly just got from bitmain I would contact them for warranty. But I'm guessing you have had them and there is a miss communication.
I think there might be a language barrier. Are you saying you just received this miner from bitmain? Or saying you have been running it a while?

I have a problem with my S4 + , as I can fix it? 
Can you tell us more. Did you get it like that? Did it just start like that?
We need a lot more info. Just one picture is hard to help on.

I could weld screws and assemble the s4 + and put it to work full functioned 4 cards, but the restart because the electricity went only worked three cards and turned it off and turn and only 2 cards this time work.
They have not sold for a bit on direct I don't think on S4+. Are you just getting it and saying direct?

Unplug and restart the system, mine acted like that once and it solved the problem.
