Does anyone happen to have older firmware for the S7? March 2016 or before.

Can we do ETH mining with Antminer s7?
No S7 is Bitcoin or altcoins using the same crypto method.

This is gold, as in comedy. I love Bitmain ineptitude and indifference to customer care, to them you are nothing more than a source of dollars, not people, they think they can just step on you, squeeze you till your blood runs dry. Vampires, man, vampires, stay away people!

And this is different from any other company how?
Its pretty simple. Don't use China RMA. Use any other option! Denver for me!

umm.. proceeded the repair they probably meant proceeded with the repair.. like the repair process.
did you think they meant procured the repair?
i dont think neither of you speaka the good english eh! oui/non?
sucks, but them is the breaks.. i don't think getting uppity is going to speed the process of your rma at all.

anyone with shipping notices for batch 17. it is due to ship out on the 23rd but sometimes they ship early
May 17, 2016, 04:49:50 PM
wow bum luck bro.. i just about did everything i could to kill mine and its going strong.
after a few hiccups for sure but nothing i could not work around.

I`m in the same boats as alot of you. DOA board on one of my S7, they`ve received my board 3 weeks ago, and i still don`'t have shipping label for it. they tell me they found the board and did the repair on it, 2 weeks later i contact them again and they tell me, no repairs are not done yet, it takes a few days. It`s BEEN 3 WEEKS for F... sake. and now i got another blade that died, it`s still under warranty but that one is going to Denver. even if if i got to pay for it.
i will NEVER NEVER buy from bitmain again. i bought 5 S7 and so far,
1 x DOA full S7. 150$ to send back and 1 month to get it back
1 x DOA board, 75$ and still in limbo
1 x board died, this one going to denver
not a very good tracking records and very poor RMA service. and all the ignores from them and run around.

that stil would not explain all three failing - the shorted board would fail, but its unlikely all tree boards shorted at once and long enough to do this damage before killing the PSU
those look like garbage 18-20awg wires, but again - this should have failed on the board with two connectors long before the ones with three.
If i had to make a guess, i would say its related to the polarity, perhaps a custom wiring job gone wrong. Im not sure though if the S7 would force such a massive power draw though in that scenario?
even the connector on the controller burnt up. I dont think its a problem with the S7 - this looks like the result of a server PSU conversion where the wires were done wrong, and a GND or 12V wire was in the wrong pin, or shorted out in the breakout board/soldering

agreed. user error IMHO. Only time I get heating up plugs is insufficient power supply wattage, or low line input voltage due to an overloaded power line to the miner's supply.
I have had two coolmax 1600W power supplies fail on S7's.....
They are rated to put out 110A of 12V and 50A of 12V (12V#1, &2 as per the sticker on the power supply)
What they fail to mention is 12V#2 is only supplying the SATA plugs and the motherboard plugs.... so you are limited to 110A in reality. And when you have all those PCIE plugs hooked to a board; well; I have two power distribution daugehter boards that have caught fire and half melted down. I since have started lopping off the motherboard power plugs and attaching PCIE plugs to them to power a single hashing board. This has balanced out the power draw in the supply and there has been no problem since...
So; Its can easily be user error.
I tend to use material provided by the manufacturer, becuase i suppose they know what they are doing and using, so i do not want to use some server- or desktop PSU's for this type of application
I have had really good luck with this aswell. Just buy a APW3-12-1600 when purchasing a S7, and so far no problems. You know by buying them the PSU was designed with the miner in mind. Most likely that coolmax did not have a S7 in mind when designing it.
On S5 and older I did use high quality ATX PSU's. But now I am using APW3-12-1600 on S7's and then go into a PDU.
+1 AGREED --> me the same doing

Yeah; It was safe to assume this power supply model was overrated, but it was literally underrated.
I have picked one up for myself at $100; It had the same power distribution board fried. I did some magic soldering work and was able to keep the power distribution and not have to solder the modular PCIE cables directly to the PSU...
Blockchainmines did a test; and the bitmain 240V ecu actually ends up sucking more wattage than a gold rated 1600w brand-name PSU...

Its not a PSU fault, the miner probably overheated and melted some solder or a heatsink fell apart and shorted something out.
Each blade uses like 400 watts so using 2 pcie wouldn't of caused this.
Looks like they lowered the price to exactly 1 BTC after the coupons expired.
Price: 450 USD
( 1.005 BTC )

See; now that's a reasonable price; period. I may order one even though I don't have the power supply to run it quite yet. I already had to shut off all my scrypt miners and some of my S3's to lighten the load on my power connection.
As far as that miner above; The only way to get that kind of thermal runaway is to either be undervolted on the supply line; overdrawn on your supply line, insufficient power supply wattage, or not enough plugs from power supply to miner. I am starting to think all 3. Also; They may draw 400W each; but overclocking or running the machine close to 75+* is a beast to consider.

Solder the wires directly onto the board and continue mining.
