People were talking about a white sticker on the portion of the hashboard protruding from the aluminum case. Right where you connect the PCIe power connectors. It was matched to the frequency by people posting about it.

Yes, there is a revision # on the PCB as well.

The v1.4 , v1.5 and v1.6 boards you are referring to, is that the revision number that is printed ~ON~ the circuit board just under the molex connector? ...or... is that the revision number that is on the Antminer sticker found atop the logic board housing?

On my miners, the circuit boards have v1.5 printed in white whereas the Antminer sticker on the logic board housing state v1.8 ... I think you can see my confusion that needs clarification.


Hashing board revs, pretty sure they are imprinted on the pcb. They are in a spot where it is not possible to verify since they are all connected to each other.

Make Bitcoin glow with ENIAC
I see Bitmain started pricing the s7's in BTC again now that BTC is up. To "support the Bitcoin ecosystem" no doubt.

Let's see if it holds up if we crash.

I wanted to share my experience for warranty claim through Bitmain @ China Headquarter. It was great, within 24 hours of receiving my B1 faulty hashboards, new hashboards are in the mail, scheduled to be delivered on Monday. Sherry Liu was great help, the entire process took less than 2 weeks  Smiley

I know I'm a little late to the party, but wow. 500 TH drop in power and same price? No thanks. I'd wait for B7 or whenever they get production back on track. The B6 should be called the Bitmain S6 1/2.

 Roll Eyes

Heh, compared to my B3, it's over 800 TH drop for almost the same price...But I'm still tempted to buy one just because its efficiency lets me unplug my other miners for more hash.


Also if you don't want to wait until 2016 and get a miner this year, S7 B6, Avalon 6 (if you can get on a group buy list) or used miner are your only option.

Is there an Official thread for the Avalon 6, i can`t seem to find any except for the ones  that compares the S7 with the A6.

i don`t want to hijack this thread, so someone just send me a PM if there is

Avalon Asics thread in hardware. near the top.

OMG 2016? Are U seriuss? That's like a month and change from being up on the website Cheesy

Seriously though, 800 TH is worth the wait. For me that is. But I'm a little more tight with my winnings than most from what I've seen.

wicked, but I am wishing for a 15-20 min btc plunge to $325-350, followed by a swift recovery, of course.
It would allow me to get B6.
Currently ~$1599 shipped, but $1350 (at btc $325) or $1450 (at btc $350) shipped would be so much better.


Hmm that PSU is 87% efficient.

But S5s "burned up" if you ran them with too low of volts?  Interesting.

I have my old Rosewill Lightning 1300W PSU running my 4.66TH S7, seems to be doing fine even though I only have a dedicated 20A 120V circuit.  PSU outputs 12.18V under full S7 load!

The lightning 1300 should do fine.  I got one long ago on a rebate deal.  It's one of the nicer ones Rosewill makes, some of theirs are utter crap.  But the lightning is high enough they made it good quality I would say.

Mine I cant remember date i got it but it has to have been running about a year or so I would guess.

Rosewell 1300 has 8 PCIE connectors. Are they all single headed or doubles?

It is 4 X 2's.   I had to go out and check I could not remember.

It's a good PSU has been running 2 underclocked SP20's.  But it's definitely not enough PCIe's for a S7.

Bought a S7 from Batch 5 I have two EVGA Supernova G2 1300 watt PSU's I want to use with it the question is The S5 when using one PSU only measures 11.88v on the PCI-E Connectors when Under full load "HASHING" no overclock does anybody think if I use two PSU's on the S7 will it give me a problem ?

Question 2: what does the S7 do when it don't get enough voltage does it BURN UP like the S5 ?

Question 3: Are there any 1500 watt 12vdc to 15vdc variable output server PSU's out there if so what's the link ?



this one goes from 10 to 13.5

https://www.trcelectronics.com/ecomm/pdf/rsp1500.pdf

I have been using it here and there.  A guy on ebay was selling them at a good price

You could always look into grabbing a router that has failover capabilities..... and tether your data connection to your cellular phone -- if one connection fails, it automatically switches to the back up connection.

I have something similar here. I have my cable connection, redundant #1 is the near by golf course's free WiFi ( they use DSL ), and redundant #2 is is a Virgin Mobile Cellular Hotspot.

I was thinking about this for a long time.

Not sure how to setup this tho.
I can setup my android phone to act like wifi router thats not a problem but I have no idea how to process further for setting up my dsl wifi router
btw I have asus DSL-N66U

Did anyone get the following error on their order when trying to confirm it.?
Can not buy different currency once.

That is with either payment options. Angry

I think it is unfair. Just because our president can't count does not mean the rest of us can't either.

Had the same issue, just split your orders up. One for miners another for the PSU.



Thanks,
problem is the shipping is then almost the same as the PSU.  Angry

I have seen several references in this forum to Antminers burning up from undervolting.  Can anybody confirm this from personal experience--especially with the S7?  In my experience with several different miners, undervolting too far can cause temporary instability and / or cores to shut off but I have never heard of any unit getting permanently damaged from undervolting.

Hi, does anybody knows how to stop beep sound when connection to net is down? I cannot find any controler of "beep sound" like S4 had. Thanks for any advice.
I don't think the S7's have a speaker to notify you when the internet connection goes down. I may be wrong but I though that's how they designed them.

I have two now .. both of them beeps like a hell Smiley ..so it does

I pulled the buzzer off on mine, and if you're careful it may actually be replaceable as the pins also come out. You'll likely void your warranty etc etc.

A small squirt of silicone sealant in the soundhole of the peizo element effectively hushes the loudness, but allows just a minute amount of audible tone to alert you if you are really close by. This probably would not void the warentee, but who knows. I'd live with it till the warentee dies, then do a tear down for cleaning of which, if it was bothering me, I'd de-solder the piezo element to PROPERLY disable the noise without stressing the circuit board.

it was noted here on a multiple occasions (first by fullzero, I believe).
dmwardjr had a post on why it is possible (something to do with electrical properties of materials at different temperatures).
From a historical perspective, not a surprise since Jupiters had the same shtick.
People even plugged openings in the boxes.

The sweet spot for me balancing hw errors and th/s is around 53, which goes against everything I know about electronics. The rev 1.4 boards I have are perfect at 51, the rev 1.5 boards are perfect at around 52 and the 1.6's are perfect at 53. I will dig for those threads since those temps will likely (?) not be good for longevity. Naturally, I can only get around those temps by observations since I use CFM since I live in Texas, but color me concerned balancing short term profitability and longevity.

I will dig for those threads.

It does.

The S7s make some real noise when the internet goes down, not sure where it comes from but it definitely does it..

I have two now .. both of them beeps like a hell Smiley ..so it does

Sorry about that guys, my bad. I didn't realize it had a speaker on it (but then again, I've never had the internet go down with mine so I've never heard the buzzer).
