Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 59. (Read 527791 times)

Yeah, swap PSUs on it and see if it still behaves erratically. It could also be your controller, I had one that was wonky like that. You could almost set a timer and countdown to when it would die. If so that's hopefully still under warranty.

Let us know what you find in case someone else has the problem.

temps are normal low 60s and overall cage temp also ok.

Again, wrong topic for that conversation.

Try using another PSU from a close by machine. What are your temps?

one of s7 freezes after about an hour powered on - I am trying to deduce what or which component is giving problems. The rigs are currently racked and tied down neatly and taking it out with the PSU will be a hassle. My guess is a bad PSU. I am using the stock 1600w PSU by Bitmain. Anyone had this situation before, comments pls, it would save me a lot of time....

Don't like Kano, that's fine. Use Bitminter or slush but don't support crap pools like F2, Ant or Eligius that are long term killers of BTC and do more damage then good. Unless you don't care if your coins are worthless.....

This is the Kano Advertising thread so of course I wouldn't expect to see anything less than another four pages of ads beginning again...
Oh wait...

If you had been mining at Kano for past year you would not be mining at a loss! Check the stats and you will see I'm right. The facts are easy to see. F2 after fees is just as bad as Eligius. Not to mention how bad they are for the long term health of the network.

In the past year I've been home mining (plus small data center mining) for an average loss of 30%. In return I get freshly minted coins from Eligius or p2pool. Still beats going to shit places like Coinbase to buy your coins and have them track how you spend them. The S7 has probably allowed me to extend my home mining operation for another 6 months or so. As long as the loss is not too much I prefer to mine my coins rather than buy them.

True. I switched to buying BTC weekly once the price dropped below $400. Hopefully price goes up and I can make money from the price rise and mining. Luckily power for me is very low so I can at least make a bit of profit still, but the miners at my home are off.

Not when you're mining at Kano.  Hahaha........we got some buffer room.  =)  Now let's hope for BTC price increase above $450 fast, we will be ok for a little bit longer.  Every issues is an opportunity.  Panic selling = Plenty of money making opportunities for the buyers.

Another +25% diff increase is the nail in the coffin for home miners looking to profit (if it isn't completely dead already) without a new ultra efficient cheap home miner coming out on the market within the next 30 days or so (unlikely).

   I think you are having some trouble with math  or english   "the sum of difficulties spike is almost always +120%"
does not make a lot of sense. Not your fault as these numbers are amazing.

  
The problem is the last 101 days look at this chart  and compare the 101 days to the 404 days before that.

The last 101 days are really fucking bad and on top of that wicked bad increase we are going up 25%

so that 2.322 x 1  101 days

  will become  2.902 x 1 in   107 days!!

These were 14 pin connectors needed for Corsair power supplies which I found on eBay for $1 plus $4 shipping from Hong Kong...do a search for "Modular Power Supply 14-pin Connector" and you will see it.  You also have to have female crip pins, wire, and a crimper to make your own.  I have about an extra 20 of these made up...I got a little carried away!  These work with the Corsair power supplies; others may use different connectors.

If anyone wants any of these 14-pin jumpers just send me a PM...

Nice- Where did you get those plugs?

Nice I like that a lot not having to have that extra cable hanging out.  Bad enough that the S7 needs 10 PCIe connectors there are enough cables all over the place.

I'm fond of these: http://www.frozencpu.com/products/5141/psu-218/FrozenCPU_24-pin_Power_Supply_Jump_Start_Connector.html

I love the EVGA ones they seem like high quality compared to my paper clip modded ones . These type of adapter are great most of my stuff I switched over to. For short term fix I do use electrical tape on the PSU's i paper clipped to make sure it does not fall out or lose contact.  But the adapters beat the heck out of it.

I wish I could remember the name.  I never bought from him but someone on the forum makes ones that had amazing looking on/off rocker switch, and I think he added led to later models.  I could not find it for the life of me though.

Nhando was stating that the EVGA PSU's come with a bridge in the box, which is correct.  If it was bought used then it may not have one but here is a $5 replacement on Amazon (and free Prime shipping - )

I just got some plugs and made these little jumpers...
