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?

My guess is your power supply for your over-clocked machine--can you swap it for a second and monitor to see if it continues to be difficult?

I tried with a Power Supply ANTEC HCP 1200W and after 3 hours de hash rate downgrade to 385 GH/s from 510 GH/s I dont understand why....
I think its not power supply. Maybe the temperature? Its operating at 47-43 ºC.... I think is not an excessive temperature...

  this is like the intel cpus the i5 2500k  if you got a good one over clock was easy if you got a bad one oh well.

I own 4 s-3's the batch 4 run great  2  close to 900gh 

the batch 1 run meh.  2 run close to 850gh

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.

lliixi you should start low then after a few hours up the frequency to the next until you find where the miner is stable. 212.5 is a good starting point then 218.75 and so on. Many here have been down this road and there is no specific setting for all to follow, what works for one unit may not work on another. You may also look back at the previous pages to see what everybody here has gone through to get a stabilized unit. Trial and error my friend.

Agreed. Some machines will take the OC and others preform badly and preferred to be under-clocked. You may be best of keeping that machine at 418.75mhz or trying to find another frequency that it likes.

Also you could try rebooting from the GUI or try a repeat reboot as mentioned a few pages back. I have notice that my machine's hash rates have dropped periodically and a GUI reboot fixes it.

My current issue is that one of my machines,  has a blade that's 4 degrees cooler than the other. 

Anyone have any ideas what would cause it?

[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?

I will try but i think that my units only are correct! Not like my Intel 2600K 5Ghz! xDDDDD

Don't put too much weight in the accuracy of the temp sensors. Is there an actual performance difference? Till it is obvious that the unit is not working properly I would leave it alone, get another temp reading device like a laser temp or even a simple stick probe and manually check the temps.

[Lowell904]

Also, the primary reason why some machines work better than others, seems to be as stated by Bitmain, the DC/DC components not being quite being robust enough.  There was talk that sometimes manufactures will sometimes push chip tolerances, which appears to be the case with the S3.

Bitmain did offer a rebate on the first 3 batches, then corrected the specs and lowered the price on future batches.

Keep in mind that this is brand new, barely tested technology.  If your machines average 440GH/s +/-5% you should be happy.

[crazyearner]

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.

yeah large variances abound form b1 to b4.

  my b4's are stable at 478+478 = 956  freq 237  power 700 watts  .732 watts a gh

my b1's are stable at 428+428 = 856   freq 212   power 656 watts  .766 watts a gh


I am lucky that the b'1s  are in a spot that running at lower freq was in my plan as sound and power use was limited.  (a friends office with power at an 84% discount)

For some  this big difference would be very annoying.

   

I believe I will order 2 more on weds or thur coming up. I think I will sell two on ebay along with an evga 1300 watt psu.

do you feel obligated when posting on ebay to disclose 428 gh speed vs 441gh?

It will do 440GH/s at 218.75 but my other machine is doing 500GH/s at 250. The blade temps are the only thing that's different at the GUI, so I'm just wondering if this is an issue  I can fix.

I think I have a thermo-coupler to go with my multi-meter. I'll have to break it out when I go to open it up.

I did see that some people had mentioned that, some of the heatsinks where not properly tightened down,  so I'll be looking at those too, but I don't think that would cause my temp drop.  I'm leaning toward an under performing component or components,  or maybe to much paste causing capacitive issues.

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.

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.  

Edit: I don't see an upgrade to the S1 coming out anytime soon, if at all.

Your are MUCH better offer selling your S1s and buying S3s than waiting for these "upgrades" that may or may not actually happen. I know these DIY projects appeal to us all but financially a miner that is just sitting around is losing money.

you have to read underclockers thread ^^^^^^, but basically you strike small R3 resistors once or twice with BB pencil, the result (once done on 4 sites on both board) is 140GH at 180W. You'll need a multimeter for this and possibly a magnifying lense.
