ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[dmwardjr]

For those wondering if the firmware fixes the issue with not having internet access potentially frying a s7, I can confirm it. My father-in-law was watching my kids today and was having issues with the wireless on one of my Roku boxes. He arbitrarily started setting static ip addresses and knocked two of my seven s7's offline about five hours ago. Both had the new firmware luckily, but one of my seven did not. I killed the port on the juniper switch with the one that had the old firmware and the fan crawled to an idle, so I can confirm beyond a reasonable doubt that the new firmware keeps the fan at a very high idle if there is no internet connection.

I asked him what time he messed with the addresses on the Roku and it was five hours ago. On both of the ones he knocked off before finding a non-reserved IP they were both beeping very loudly, but the fans were spinning at a high rpm. During my test on the one with the old firmware the fan was barely spinning, so for the father-in-law variable the last one is updated now. Hard resetting them both allowed them to recover, luckily I am anal and log dhcp assignment and errors to syslog. It only took me a little while to figure out that he picked addresses that were in my reserved dhcp exclusion range.....

Neither auto-reconnected, which I find to be an interesting design flaw or bug.

Sigh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Allright thanks.

I'll also see what will bitmain answer me for that question and will post here.

They say new batch will be available for sale next week and i asked if the problem will be still there just in case.

I've read half of this forum and for a newcomer i could not find anything exact and promising on both of these issues : 1. when will new batch be available for sale? 2. fan thing.

So maybe their answer will be more promising

It appears to be fixed according to the link I provided.  If you are still queasy about it, you can take your fans off "auto" and set them to 90% or 100% manually.  We already know if the internet is down with the fan set manually, it will continue at the manual setting whether the internet is working or not AND thereby keep the rig from burning up.

Uh ok great. Sometimes we all need to be told the same thing several times to believe

Thanks.

Here comes their answer:

"Yes, all issues should be solved! each batch releasing developed."

Thanks Kogan.  Much appreciated!

Time to sleep.

May the blocks be with you!

Hello to you all.
Received my ANT7 Batch 1 yesterday.
Also received the PSU from Bitmain.

Yesterday i pluged everything, configured and "voilá"... it was mining...

Everything OK by 2 hours... after that the unit started to beep.. i needed to poert it off.
Connected again... and once again it was mining.

After 2 hours the some problem... the mining decrese to almost 0, the unit started gain to beeb.
Power off and power down again
The unit beeps again and again... works for 3 to 4 minuts until it stops mining

From 21PM yesterday the unit is producing ZERO... its beeping almost shure (i'm in home, and the unit in in my office).
The ANT7 is connected to a swhitch and then the switch is connected to a router.

Im a newbie, and i thought this was power on and let go... i see its more complicated for a 2500€ machine.
Is there any troubleshotting guide?
Help is needed.

Did you try using a different pool?

Did you login to the miner and configure it or simply plug it in?

Dogie, would be a good one to talk to at the following thread specifically for the S7:  https://bitcointalk.org/index.php?topic=1194785.0

There are many others in THIS thread who are quite capable of helping as well.  The chances of many of us being awake at this hour is not very good.  It may be that I can help...

You can start by posting a screenshot of the "miner status" in this thread and the other thread I gave you a link to so you can see who answers the quickest.  We also need the manufacturer of your Power Supply Unit (PSU), model, watts, etc...


If you don't know how to post a screenshot on here, follow directions below:

Go to imgur.com

Click "upload images" at the top of the page.

Drag your image(s) to the page for upload.

Once you have dragged all the images you want uploaded to the window, Click "Start Upload."

The image I have posted below will provide instructions in text bubbles for which "link" to copy and paste in the forum.  So, look at the image below for further instructions:

{If you drag multiple images into the window for upload, it will only provide a link to the image and no option to post the images themselves in the forum.  Either way is fine though}

dmwardjr-------I have to say that you are a very good person!!!!   You have helped me in the past and are continuing to help other to the best of your ability.  Just from me, Thank You!

I just received a shipping notice from UPS for delivery tomorrow for an order from 10/18; although, it is still showing Unshipped in Bitmain.      I still have more orders on 10/24 and 10/25.

was it b2 or b3? it would be helpful to know.
my 10/16 b2 order is still nowhere to be seen.

Why did they make batch 2 available anyway if they don't deliver it at least on par with b3, without even considering that one might expect b2 to be delivered BEFORE b3 as the common logic suggests.

So I ordered my batch 2 on the 29th of sept I paid on October 5 and mine will arrive on the same day as you.

Plus you paid with btc that rose in value so I am sure you paid less btc then me.

I figure the early batch 2 buyers were overcharged about a btc compared to some one like yourself.

Not hating bitmaintech but poorly handled by them.

Well when mine comes today hopefully it works well.

Here is the difference between stock firmware and oct 23 600 firmware running 15 s7's against nicehash.
If you look at the start on the left for about an inch that is the stock firmware running.
After that all oct 23 firmware. The downward spikes are rebooting on my end for naming configuration.
Two more s7's from oct 12 order will arrive tomorrow.

Thanks for the image tip dmwardjr.

what's green and what's blue? are we comparing first inch of green with the rest of the green or first inch of blue with the rest of blue?

Very interesting. I assume everything was set the same, Frequency extranonce etc? Would be instructive if Bitmain would let us know what the differences were?

The green is the pay rate which you can't see in the graph.  The blue is the average hash of the miners, show in Th on the right.

Well if I can run one of these bad boys off of 2 HX850's, I am going to have to sell my last S5 and S1-S3+ upgrade (OC'd and hashing at 500 which is sweet and reliable) just to get one out of the next batch so my 4 HX850's can be used.  Guess I'll have to test it first to see if I can reliably do that.  I worry about pumping 800 Watts through a PSU that's rated 850 Watts.

It would probably work, but the S7 I'm running of 2x PSU's are a lot more unstable than the ones I run on 1 PSU. 100 GH/s lower as well, and can't handle overclock at all.
100 GH/s more on the ones I run of Bitmain's PSU and an EVGA 1600W G2.

Multi-meter readings show a 0.1V difference on the dual PSU setup, compared to 1x PSU. So the problem might actually be that the PSU's themselves. Running 2x boards on XFX1250 and 1x board + controller of a cheap ass Corsair 650W.
