No

The only way to know for certain is to have the cgminer log which will show the first 4 non zero bytes of the block hash next to the diff.

These standalone devices don't like setting the logging (due to extreme space limitations of the cheap hardware that runs linux in them)

Yeah thanks for the input, tried all the steps, found the sweet spot: 196Gh/s @387.5mhz with 0.9%HW... not bad... I'll reload the old firmware... just waiting on an announced 7hr internet downtime :-(

My thoughts are that you should go back to the old firmware and also do a moderate overclock something like 375 and take it from there.

Long story, but one has never clocked to 400 without 10% more errors than the other. They have the same cooling (lots), I've tested power supplies, switched control boards (I also got one replaced by sushi) and can't narrow it down... the only difference is the larger capacitors on the newer boards, which I noticed after breaking some off, so technically one is now broken, but is working exactly as it was before the repair. I figured the upgrade wouldn't hurt, but it hasn't helped at all.

Yeah I think you should go back to the old firmware.

Why did you upgrade anyway?
Was it broken?

Nope, not on wifi, on ethernet straight to the router and nothing has changed in my network settings. The thing is that it doesn't need my pc to connect to the internet, it connects on its own and hashes fine, it's just that on the last 2 evenings and this morning only one of them (not always the same one) would randomly stop hashing and start beeping. Originally I just turned it off and on again, but last night I logged in via the gui to check the log and make sure ntp client wasn't on and it just started hashing again. Then, it did the same thing this morning with nothing in the log.

I have 2 machines with the same settings, connected to the same router, hashing on 1 address at the same pool... I would expect both of them to go down if it was either the pool or my internet connections or my network settings, but it's at random times and only 1 of them will go down while the other is fine... just strange and was wondering if anyone else might have noticed that... I've had them for more than a month and they've been very stable, running for days without interruption, until I did the upgrade... I'll keep an eye on them and if it continues I'll load the backup firmware and see if it makes a difference.

I am guessing there is something wrong with your network settings.
If it only starts hashing when you log in it means it is using your pc internet connection not it's own.
Or at least that's what I think.
I am guessing you have it on WiFi?

Have you tried putting a +5v load on it?  I have that PSU (coolmax zu-700b) and it requires a +5v load to stay running.  I connected an old CDROM drive to mine and it runs 24/7 just fine.

I must say that since updating the firmware from the github a few days ago my units have started to lose connection randomly and start beeping... once I log in via the webgui it stops beeping and starts hashing again with nothing in the system log... strange!

If your network is a private network and not a 192 home network, you should do an ipconfig on your PC or laptop first to get the full address IE 130.160.xxx.xxx whatever IP it is.

Take note of this as the gateway is going to be the same as the first 3 octets, except the last one will end in .1

You'll probably want to find out a free IP on 130 network either by getting it from a network admin or using a utility like Angry Ip Scanner.

After factory resetting your Antminer, you'll want to manually configure your Laptop/PC to be 192.168.1.100 or anything on the same network as the IP on the Antminer sticker.  Plug an ethernet cable into the Antminer directly from your Laptop/PC, then open a browser and connect to 192.168.1.99 or whatever IP is  on the Antminer sticker.

On the Antminer config page, go to Network > Interfaces >WAN > General Setup

Change to Protocol to Static, then in IPv4  enter the free 130 IP you got from your admin or Angry Ip Scanner, leave netmask 255.255.255.0, change IP Gateway to the same 130 address, but change the last octet to .1, Broadcast should be same as IP Gateway but instead of .1 change last octet to .255, Custom DNS should be 8.8.8.8

Check off Disable DHCP then click Save and Apply.

At this point your Antminer is configured for your universities network, so unplug ethernet cable and plug into school network.

Reconfigure your PC/Laptop for school network by changing back from 192.168.1.100 to obtain automatically.  Point a browser to the 130 address you gave the Antminer, login, then go to Status, Mining Configuration, and plug in your Pool, Worker, and Password.

If this doesn't work, please post some screenshots so we can further assist.

Can he just buy a router plug the University internet to it then all of his local ip will be 192. whatever if he can not find the ant?

My First Unit was a 600 Watt one ...

my Any is not Over clocked at all

The new Power Supply is a Coolmax  ZU-700B   700 Watt

sounds like a faulty or underpowered psu.  Is your ant overclocked?  and what is your psu that you are using for it?

Anybody have problems with their AntMiner Just shutting itself off Randomly ?? 

Ok, I think you might be misunderstanding something: you need to set the ip address of your pc to something different to 192.168.1.99 or it will conflict with the miner, if you set your PC to 192.169.1.99 they will never connect. I'm sure the miner will be 192.168.1.99, so you need to change the ipv4 of your PC to 192.168.1.2 and then connect to the miner by typing 192.168.1.99 in your browser. You'll then need to change the ipv4 address of your miner (WAN) to something like 130.160.[this must be the same as your university range].200, or try setting it to DHCP client for it to be automatically assigned an IP.

Your problem is that your miner is on a different network to you uni and you need to get into the miner to change the WAN IP address so it can access the uni network... the easiest way to do that is log in to it with an ethernet cable, but your pc needs to be on the same network as the miner to do that i.e. 192.168.1.[whatever].

I tried holding the reset button for twice that long and then shutting it down, leaving it off for a while, then starting it back up. Then when I tried to set my IP to 192.168.1.99 or 192.168.2.99 and connect to it but it's not there. I doubt the router is 192.168.1.1-- This is a university network so everything is 130.160.XXX.XXX instead of 192.168 and I have no ability to administrate a router or anything like that. Are those settings in step 3 supposed to be for my computer or the miner?

My Ant had a little block party yesterday.

Is there a robust solution for keeping stats externally? If the pool drops out the stats disappear and start over.

1) hold the reset button for a full 6 seconds before releasing.
2) It will now be at 192.168.1.99 (or 192.168.2.99)
3) Assuming your router is 192.168.1.1 - static IP
 ipv4 address: 192.168.1.99
ipv4 netmask: 255.255.255.0
gateway: 192.168.1.1
Broadcast : LEAVE THIS BLANK
custom dns server: 8.8.8.8
Disable DHCP

4) if it still wont work, what are your pool details and post some screenshots

I don't have access to a router I can administrate here.


That's the guide I was using. And I tried pressing the reset button. Is there another way to do a hard reset?

Go here and read from the beginning, it should get you going: https://bitcointalksearch.org/topic/setup-troubleshoot-bitmain-antminer-s1-180ghs-miner-344970

Do a hard reset first as you may have messed up some of the settings...

Good luck!

Edit: P.S. just disable ntp client if it's a problem.
