when I swap psu around; either psu works and I've test the terminals and they all read 12v as they should..

so.. red light on s5 = bad board?

should I troubleshoot the board or something..?
I sent email to antminer.. but I suspect it may take some time to hear from them..

***********just a sec.... I'll clarify with a pic...***************

Red light on s5 is good, if red light out bad.

Red light on controller board is normal.

Do you have a red light on each hash board near the power connectors?

Yes the pic of the flat hash cables is normal with the red light.

how do you test the psu terminals?

under load or unplugged?

make and model of psu and show me how you test the psu volts?

the symptoms you show so far are poor quality psu.

and under load 12 volts is very difficult most psu sag a bit mine are 11.96 under a full load.

I think that boards temp discussion is very interesting.
I am in fullzero camp that says that increased board temp is beneficial for speed (at least to 56C from 51C in my case) with everything else being equal.
However, what is the best way of raising temp?
At least in my case, i found doing so by lowering fan to be tricky: I had an occasion of miner losing login and killawatt going bad and essentially disconnecting the miner AFTER i was trying to lower fan. Maybe it was just a coincidence, but I also saw intermittent X on one chip at fan setting 60 or so (incidentally, whichever setting results in ~3900 rpm, this produces the most annoying sound with anything 5% above or below being much better).
To me, it looks like raising board temp to 56 by partly closing the door to "mining" room or providing slight obstruction (by tunneling the exhaust) to the air pass resulted in temp rising to 56 and ~40-50GH more hashing. I did all attempts at frequency 600.
The main question is: would rising board temp to 56 or even 60C affect the lifespan of the machine? In S5 it did not, but it remains to be seen here.

When I first connected everything as:

2 PSU's (1000 watts ea)
following the antminer s7 manual configuration
everything was working just fine 4.xx gh/s and all chains up..

then I a few days later I noticed only one chain was mining.....
I've been troubleshooting:

1) physical reset
2) reset in miner settings on website
3) reboot
4) swapped psu's..
5) lowered the frequency..

nothing so far seems to be bringing the other chains online.....
any ideas?
looking for any support I can get to bring those other chains back online!

Thanks in advance!

******************edit / update *************

just some amplifying data..
from right to left (standing on side where network plug goes in facing the fan) , after the 4th plug.... (before the 5th)
there is a red light on (not sure what that means)

The red light means that hash board is working. Guess the other two are not.
S5's have red lights also, when they are not lit hashboard is bad.

edit****
Oh you mean the red light on the control board by the flat hashboard ribbon cables?
I was talking about the red light on each hashboard by the power connectors.

I suspect low quality psu.

make and model of your psu's would be helpful

I just got a UPS notification for Package Scheduled for Delivery Tomorrow. I do have 5 orders outstanding, but didn't know that any were shipped.

What is your order and payment date thanks

Date Batch Bitmain Info
9/9 (B1) Unshipped
9/18 (B1) Unshipped
9/29 (B3) Unshipped
10/03 (B3) Unshipped
10/18 (B3) Unshipped

The 9/9 order I just received information through UPS that it is out for delivery today.

Have 21 ordered starting 9/3. Have received one. Seven weeks is really painful.

Update on my OCed S7 - It's a tank:

https://i.imgur.com/mqGht7p.png

Looking good!

Just, if you increase the temp your HW will go down. Temp between 50-60 are the best for the S7

I think this is an excellent result, best I have seen, for an S7 at 650MHz with some amazingly low temperatures. In general low temperatures are good and give improved performance, where is the evidence that the S7 runs better at 50-60?

Rich

They actually run better around 62c. If you have an S7; set the fan lower to increase the temp the correct amount for your specific ambient. This should be somewhere between 30-45 fan speed. You will see lower hw. .

I lol'd, but then felt sorry.

With my S7 it's working fine. HW went down big time

Not in the Arctic or in my freezer lol. Close, though. Canada.

How cold air are You feeding them, I'm planing to update my garage heating to S7.
My S5s don't like cold air at least undervolted.

I just use variance as much as possible! maybe i will take a picture Wink

8pin CPU to 6pin VGA is a must! don't run your s7 without it unless is underclocked or you power only 2 blades!

About the LEPA 1600W psu, i use 8pin CPU to 6pin vga adapters and i have no problems!

My batch 1 is online for 1d14h10m58s running at an average of 4,811.82gh on LEPA 1600w

I want to power my s7 with a LEPA 1600 also.
do you have time to explain or show pic I'm unsure because of the rail distributing.

I think i will use 2x 4 pin Molex to PCI-e for the control board

I than have 8 cables left, I could use 2x 4pin Molex to PCI-e on one of the boards?
I have them available.

CPU to PCI-e I must buy first.

Safety is my main concern, I will do no over clocking till warranty is gone.

S7 works great with Lepa 1600
If you would like to see live hashrate overclocked s7 with this psu check my rig
