Batch 4 order: 2014-07-24 20:27:17

Still unshipped. No record of Order ID on the UPS site either....

B4 Order: 2014-07-24 15:18:01.0

Received shipping information today, guess you will get yours also soon

The shipping of B5 started, 7 days earlier than promised date. We added more B5 units for sale.

Excellent - I'm just waiting for my wallet to synchronize...

Why not using Electrum or Multibit?
Instant synchronisation with the block chain.

Yes "warranty' have not much value in the mining hardware.
41 - 42 was my temperature peaks at stock clocks.
I don't have any link to the thermal grease for now.
I'm searching for it to buy the same brand or the alternative one having >3 conductivity.
But most of the products I'm seeing is of conductivity 1.
I will post here the link if I find it or some else who has experience in doing this will support here.

They are talking about removing the front-side heatsinks, right?

Yes its about the front heatsink which is directly attached to the ASICs.
Need to check how efficiently they did the inside heatsinks.

[allcoinminer]

Several hours ago I posted a screenshot asking why I do only have ~250GH/s while the miner is powered with a 1600W PSU and all ASICs looked fine. I restarted the miner and let it run a few hours. Now it looks like this:

It seems that some ASICs can not be detected. What can I do in this case?
Thank you

Have you taken the unit apart and checked your thermal paste?

When BMT recommends checking the thermal paste, are they talking about the front-side or back-side heatsink?
There are two per blade. Is it pointless to remove backside because there are no SMCs?

They are talking about front side (the ASIC side) small long heat sinks.

Check your cables.  Open the cover of the S3 and make sure that the both blades have their cables plugged in correctly.
That one board is just not hashing at all.  That's why the temp is so low.  If it's not bad power (PSU) or cables it's likely an RMA.

try diferent PSU (yes i know its 1600W, but really sometimes just PSU is bad)

The thing is that the temps are so low on chain 1 in this pic and your previous one. Something is not right with that first blade. As others have said check out the thermal paste but I think it may be something else. I would contact Bitmain for a RMA.

Your temperature on one of the blades is too low. That means some chips are not running.
That's why its is shown as "-" in the ASIC status page. "-" may possibly be damaged chips. not sure about that.
One of the fans speed at 2340 is also a bit higher than normal.
All the above leading me to think its a heatsink problem. Maybe the chip died after overheating.
Try to remove all the front and backside heatsink and check.
Also try interchanging the PCI-E power cables before going for a  heat sink check.
Hope you are already in discussions with bitmaintech.

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience..

I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months.
(I'm a newbie regarding mining, so with this miner I can use it for multipools right? )

I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks.  Here is a list of the historical increases.

https://bitcoinwisdom.com/bitcoin/difficulty

In the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months.

Bitcoin mining is nothing more than an "arms race". You need to keep increasing your hash rate to keep up with the increasing difficulty if you are looking for "steady" income.

What about B4 ? That hasn't even started shipping yet has it?

Mine shipped on 7/29 and  is scheduled to be delivered on 8/1

When did you order?

ANTMINER S3 -B4 × 4  @ 2014-07-24 22:28:43

B4 x 6 @ 2014-07-24 14:45:04

Thanks. Maybe they have actually shipped and I just haven't had the notice - that's happened before a few times...

Nice to see a fellow from my hometown Nottingham Dunno about that Liverpool avatar though!

Well, I'm from Liverpool, lived in nottm for years then moved to derby. Really my username should be livernottmdby - but the avatar stays

That is the best analogy I have heard yet, and just like the arms manufactures the mining manufactures are making the $$$$.

Quick question about temperature.  I'm hoping to run these devices (12 of them) for the next 6-12 months but where I want to run them is not temp controlled and will be below freezing temp at some point.  Will that be an issue for these things to be getting that cold?  I plan to leave them running and they won't get frozen as long as they are running.  I could see them turning back on from frozen being an issue but I can work on that also.

Any thoughts here?

Thanks

I wish i could say that, miners will heat that room up for sure.
They generate heat quite well.

is there a heater available? perhaps set the heater on 50 degrees or so as a backup to your mining heat. You don't want pipes to burst... Always plan for power outages, storms etc.

This is a garage space that I will not have to pay power.  Pipes are not an issue.  There is a heater to bring up the temp if they are turned off and reach below freezing.  Just exploring this option as it is cheaper and then I don't have to worry about the heat effects in my house.

Power outages/storms I'm not worried about.

Thx

cold will not be a problem, condensation could be your worry if you have any power outage.

my 2 batch2 units have been up an mining b/t 390-420gh/s for a little over a week - no issues.

today - they both stopped (about 2 hours ago)  - both 'miner status' pages show 'no data yet' -  

pool info is correctly set -  

I've soft rebooted.
I've powered off and re-powered.
I've even updated the firmware on one of the two

all to no avail.

looking at the logs - nothing jumps out -

any troubleshooting advice?

Please Help!!

This happened to me, my gateway was wrong. Check all your TCP/IP settings and reboot. Possible change your DNS to 8.8.8.8  Make sure to reboot after any changes. Maybe change the 2nd miner DNS to 4.2.2.2 . Do a hard reboot also.

Very weird both would stop hashing.  Are they on the same PSU?

Do you have a failover pool set up?   It could be your main pool having a problem.

do you have your backup DNS info?
I use :
4.2.2.2
8.8.8.8
8.8.4.4
