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...***************

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

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

that is wonderfull, but hooww did you connect it'?

did you only set up the frequenzy to 650 mhz to get 5.2 THs or did you any changes else?

. You all seem to give a fcuk on anonymity and also give a fcuk on keeping the chain well distriputed and healthy by your greedy poolmining...


Hmmm.  Using BitcoinCZ stats as a basis, my current 6.7TH of ASIC farm ((2) S3s, (3) S4s) pays about 0.005 BTC per found block and that pool finds half-a-dozen or so blocks a day.  If I'm doing the math right, if I solo mined BTC and had average luck, I could find a bit under 1 coin per month solo mining, or 25+ months per block.

Is that what you recommend?  Run for 2 years and hope I find a block, with nothing in between?

Seems to me that unless your spending thousands a month in electricity, pools are not really an option anymore (e.g.  "not an option, a necessity").



I think you did not get the point...
BTC is centralized more than ever, you are complaining about not getting your miners from a "legit" company like BITMAIN, the so called ROI's are shifting more and more over to more than a year with investments that are quite huge taking your monthly sallary into consideration just for getting a glimpse in a very volatile payment system that was thought for another purpose.
If you take a look at BTC at the value it is today, it probably would be smarter to buy BTC for the ammount you invested in your gear that is out over a month now and you are loosing value on your investment.
I did some maths, and my conclusion was to sell my gear and hold the ammount of BTC worth the gear, sit back, have a coup of tea and take a look at the value in one year from now.
The probability that i loose some of my holding in the event of BTC crashing back to $10 is less compared to the market value of my gear at the same event.

Well, if you do your maths, there will porbably pop up the same conclusion that occured to me with raising power costs etc....
If you want to mine, set up your own pool and go for it, that would be in the meaning of BTC along my comprehension.
I am not stressed with power costs, heat (which is good if you can use it to heat your home or your water), noise, failing hardware, not getting your hardware, your wifes complainment(naging) and so on.

Guys think about it. The fraction of home miners is currently a drop in the bucket compared to the raising "industry" at the moment speaking and please keep in mind, that the home miner is always served last with hardware that is one evolution, maybe two, steps behind of the development speaking of 0,06J hardware in use at the moment speaking.

I personally have no interest in beeing the dumb cash cow of the industry anymore.

Concluding i will turn my back on BTC and use other currencies based on another protocol than BTC to have truly secure, private and anonym possibilities to make my transactions besides FIAT  Roll Eyes

Indeed, it amazes me how many people still buy into mining hardware at crazy long ROI valuations/specs.

It is indeed easier to just buy whatever coin you desire and sit on it or trade etc than to mine it.

This is assuming you dont have free electricity and/or free hardware to mine with.

Yeah, well greed is one factor for this, the other is the habit  Roll Eyes
