ANTMINER S3+ Discussion and Support Thread

[Lowell904]

One blade runs at 37 degrees while the other runs at 41 degrees all on stock 418.75mhz.

Any ideas what's going on before I take it offline to open it up, and lose some of the 440GH/s is generating?

One simple idea would be to check the heating up board by opening up the miner and seeing if springs got caught up in a burr, therefore preventing tight contact between front heating sink and hashing chips. If they are, maybe tighten them up just a little bit and then check to see what happens. I would not recommend applying new paste because it did not do anything for me at all. Top line of "oooo" correspond to the left board if you look at it from the direction of the ethernet port.

Thanks,  that is helpful.  I do have some new paste on the way,  just in case I decide to go that far with any of them. I'll poke around with a screwdriver and temp probe and see what I find. I'm gong surfing first though, I need a little R&R.

Hey Bitmain, any info on B5 shipping yet, one post of yours said you were shipping a week early instead of the 7th.

Ghash has been INSANELY lucky over the past 48 hours. I'm up over 100% in the past 24.

Hi!

Im a new miner from Spain, Barcelona. Best regards for all!

I have two questions. I hope you can help me because i dont have any idea to find the solution of my problems.

I have one Antminer S3 B3 and one is working with 2 PCI Connectors @250Mhz and hashs at 500gh/s but in one hour and a half the hash decreases to 360-380 gh/s. How is it possible? The status of miner appears to be OK, without any "X" or "-"... Somebody knows whats happening? if i reboot the S3 the hashing push up to 500GH/s but in one hour and half decrease too...
In the status no HW errors and nothing strange. Only i can saw is a Little decrease of temperature... 47-44 grades @500GH/s VS 46-40 @365-380 GH/s.  

I observed that my miner works more stable with 2 PCIEX connectors tan 4. How is it posible??

And the second question is for the second S3 B3.

I tested 250Mhz, 237Mhz, 225 and default 218.75 but always i get a lot of HW errors. How can fix the HW errors?? The only speed that no cause HW errors is 212Mhz.
I think the temperature is not the problema because its working at 43-43 grades.

Two S3 antiminers are working with the last available firmware of Bitmaintech and are new. Arrived this week.

Can you help me?

PD:I hope you can excuse my English

Anybody?

The reason no one has responded is because your issues have been covered multiple times in this very thread. Your symptoms are exactly the same to what many of us here are experiencing.

At this time the only things that have a CHANCE of helping are re-pasting the heatsinks and setting up a restart routine.
Since I've added '/etc/init.d cgminer restart' to my crontab I've seen my 24-hour hashrate increase from 410 to 480 on my GOOD units. From 398-420 on my "Bad" units.

It will be a crapshoot, the front-side heatsinks are not engineered very flat on their contact-side. I think someone said it best when they suggested tightening down the HS like changing a wheel. Alternate the screws between innter and outer. 

After some fiddling I was able to get all of my temp sensors reading within 1C of each other and get stable hashrates with a restart routine and heatsink reapplication.

Some people are more code-friendly than others. chrontab is a bit too much for me right now.
what would be the string of code to put in after sshing to miner and in what directory?
If you don't mind, show us all commands, please.

You should contact Bitmain.  Perhaps they can include that modification in a firmware update.

I have already contacted Bitmain about adding a restart timeframe to the firmware. (Much like many of the SCRYPT mining controllers)
BEAR IN MIND, I AM AWAITING BMT ENGINEER'S ADVICE REGARDING RESTARTING THE CGMINER PROCESS SO OFTEN.
There may be a reason they didn't include it as an option, but I'm more apt to believe that they simply just didn't think to do so.
That OpenWRT controller is still VERY MUCH a router.

Here's the rundown. It's very basic stuff.

SSH into your miner

crontab -e

This will load up the crontab editor, the usage is the same as Vi
Press I to enter 'Input' mode.
Add the following text below the monitoring script.

0,30 * * * * /etc/init.d/cgminer restart

After doing so, press ESC to get back into command mode.

Type:

:wq

This will write your changes and quit.

Type:

crontab -l

This will let you see if your new entry has been added to the crontab.

If it's there, you're good to go.
If not, Google how to use Vi or read one of the many posts in this thread that explain it.

How often does cgminer restart with those settings?

I have a problem. My "Authorized Distributor" has done the following.

I (stupidly) agreed to overpay on batch 1 S3 because I wanted a batch 1. They usually make money especially batch 1 where you have good clarity on what difficulty might be when they ship. I paid very early on July 1.

I received my confirmation emails. I re-checked my account after end of business later that day. So far everything was in order. Batch 1 S3 etc.

2 weeks about go by and I pop in to check my account to find out when my Batch 1 order will ship to discover it's a magical Batch 2. I have no idea when it was ordered, what point in the queue it was at or anything. At this point I have received 0 contact from distributor. Order was altered 25.5 hours after I placed it. I wish I had known I needed to babysit this order to keep things on track and at a price I could live with.

I notice in my account there is ask us a question. So I ask if they can fix my Batch 1 order to actually be a Batch 1. I really wasn't thinking that someone intentionally changed anything but that there was a clerical error.

24 hours pass still no contact from distributor.

I send a message to the person who has their email on my receipt (I dug it up just to ask again). I was not nice about it. Reply was received in 3 hours. Nothing too helpful just an offer for fair compensation. What is fair for bumping me into a cheaper batch, failing to ask me about changing my order, failing to ask about re-pricing my order? At this point I didn't want a batch 2. I never wanted a batch 2.
 
I asked within 3 hours for the following, after apologizing, What my total refund would be AND what my "Fair Compensation" would be.

Within 12 hours the disputed order shipped.

No answer Friday, Saturday, Sunday, Monday or Tuesday. Email was sent late Thursday. As of Monday late my order finally finished its warehousing. Tuesday I send another email asking if distributor would please reply to my last email. Last email included in current email.

Wednesday I get a reply. Here is your tracking #. Batch 1 and 2 shipped about the same time. I have to refund the 7.7% for specs and I have to refund 0.02 for the price difference. Let me know wallet address.

I reply I asked for full refund and fair compensation. Order is complete when package is accepted I have not and in 7 days UPS will return your package to you. I point out I still wouldn't have paid shipping on Batch 2 (ordering from bitmain) and told distributor I figured the 0.1115 over the cost of batch 2 directly was fair compensation at this point. I notified distributor that I was interested in either 0.1115  or a full refund and they have until the package goes back at that point I expect a full refund.

No reply in 48 hours. Send email to admin because I get an order complete email. I point out 1.48 is better then 0. Ask what they would prefer.

48 hours more still no replies.

I really would like a way to deal with this that doesn't leave me with a more then Batch 1 priced shipped same as batch 3 held in China for 4-5 days batch 2 then left at UPS because I have an issue with the questionable way this has been handled. Most of this is the price of business

I will contact you today with a fair solution for your problem.

Apologize for the delay

Regards

Juan

OK so funny story..... He didn't contact me at all.

So is later today before close of business East coast? It doesn't seem so.
Oh I know its got to be West coast close of business. Didn't happen by then either.
How about East coast Midnight? Nope.
West Coast midnight? Nope.
24 hours after the post? Nope.

Maybe he intended to say at the one month anniversary of the change. Whoops missed that too...

I don't know what later today was intended to convey but it said to me that I should have received something long before now.

Maybe next week will go better. It can't go worse then picking up the units 10 hours before my distributor resurfaces magically to offer compensation. its only 18 days after first contact with them. 31 days since the change. Maybe making it over 21 days since I notified them will make things better. I doubt it. Had I not picked them up would he have offered a full refund.... the world may never know. I know I won't.

At this point I am sure I have the most expensive s3 pair. I paid 1.5915. I have no missed hash rate refund as Juan keeps implying I can't have it unless I agree to his fair offer. So anyone else not able to collect a manufacturers refund?

Glenn

Sorry for the delay we just processed your request and refund you the amount you ask us, to the wallet provided by you ending at "v7Trg"

I apologize for the delays

Please confirm if you receive it ok.

Regards

Juan

Yes it did show up.

Thank you for sending it!

SO has their been any news from Bitmain regarding the s1 upgrades yet or this still a no go. As I see can only order from them for them in pairs of 2s and wanted to maybe buy 3 units and also buy upgrade modules for old s1s that are now beginning to collect dust.

My S1 is still profitable at stock speeds,  but you might want to try under-clocking and under-volting, via a pencil mod, as I will be doing in a month or so. This will improve the efficiency  of the S1.  

What exactly is a "pencil mod"?

Here is the link:
https://bitcointalk.org/index.php?topic=526060.0

THANKS! Exactly what I was looking for. Now that I have replaced all my S1s (10 of them) with S3s I may try this with a few of them.

Hey Bitmain, any info on B5 shipping yet, one post of yours said you were shipping a week early instead of the 7th.

did you check your e-mail or order? my b5 got shipped last night.

Nothing in email or on order page, I have two orders of 2 units each.

it restarts at 0 minutes and 30 minutes every hour, day, week, and month. Basically every 30 minutes but on the hour and on the half hour if your clock is correct.

An easier way to do this if you don't want to mess with crontab is to use the web interface. Go to "System"->"Scheduled Tasks" and just add the 0,30 * * * * /etc/init.d/cgminer restart command there. Save and Apply.

[MoreBloodWine]

Every half hr, lol, thats waaaay too often.

Once a day or every 12 hrs should suffice.

[aztecminer]

this is 8 out of 9 S3 ants hashing at or above 441G/hs @stock clock ..
i ran out of thermal paste for the 9th is why its not up yet ..
i have 30 grams gc-extreme thermal paste due to arrive monday ..
i have not tried to oc them yet but i might try next week ..
it's all about giving these the right amount of loving is all ..

Im thinking about getting 3 of the 5B ANTMINERS for when i go to school this winter for 8 months. I'm just starting mining for my first time do you all think it's worth it for a newbie?

[danny3614]

if anybody order the antminer s3 by bitmaintech.com?
is that reliable site to order?
