You need 4 PCI E connectors though.

Nope!  Again, please look here.

Though I don't plan on running them at 250M clock in the long term due to higher HW % (though still tolerable) and a much higher wattage, I rebooted them to 250M clock again about 3 hours ago so I could take a screenshot and post it here since I failed to do it in my post linked above.  I'll let it run and stabilize a bit more though before I take a screenshot.

Anyone else having issues with discarded shares? I hooked up my 2 new S3s yesterday and have 60k discarded vs 11k accepted as of this morning,

Also, One of the S3s does not show the fan speed but I can see it running. Is there an update for this?

3rd issue: One miner only mines at 415 GH/s. much lower than the advertised 440. Again, is there an update? The other one mines constant at 450 GH/s.


Thanks in advance.

Are these in stock clocks or you overclocked them? Which batch is this from?
Which Power Supply you are using and how many Antminer S3-s are connected in it?
Also post your Miner Status page here from both the S3s.
Also show your pool data by hiding the username and password.

They are stock clock from batch 5 running on 2 S3s on one Corsair RM 1000. The hash rate has come up but it's not too stable.
Any idea about discarded shares?
you can see in the second picture what I was saying about fan speed missing.

the temps are decent so  other then the fan speed meter
 your miners are great  discarded shares are a meaningless stat.


the math for miner 1   hw/diffa + diffr + hw =  83/4965376+11776+83 or 83/4977235  = .000016675 x 100 = .00166 percent error rate.

accepted shares are 19396 on miner one

accepted shares are  19617 on miner two  close to the same for the same time   and the av gh = 440 and 438  which bears out to your accepted share number


the 5 second speeds are bs they move all over don't worry about them.

  for shits and giggles do the error rate for miner 2 

it will be about  .0333 percent  that is 99.67 good.       and 98.00 is pretty much passing.

That HW seems high! I have 1600 HW after 13 days of mining non stop. 452,000 shares accepted and 1600 HW. This is also with 250 frequency.

A cx600 would be useless to over clock a s3! I need 2 cx750 to have two overclocked s3s

Why do you say that?  Have you actually run an S3 with a CX600?

Even if an OC'd S3 draws 450w at the wall, it only represents a 73% load on the CX600.



That's not really how power supplies work. Overall wattage is not the representation of how much power it can give on the 12v rail.
The cx600 has a 46A on the 12V rail, this is 552watts. That's 81.5%load without the added power draw from the wall minus efficiency of the power supply.
Seems it only comes with 2x PCI-E adaptors, so you would need molex to PCI-E or sata to PCI-E if you wanted to connect all 4.

Under my account I sent a message on bitmaintech.com and now my message options have disappeared, has this happened to anyone before? Please help, thank you!

Must be a change on the site.  The message options are gone for me too.  I had attempted to communicate with them via that method before, but it wasn't until I sent an email instead that I got anything back.


Okay so it is not just me. I am curious as what we do now because I seen the only options for support or shipping problems was through the messages section under accounts.

Gone from mine as well. Did you e-mail address did you get support from them? I need to ask them about a dead miner I have. Thanks!

I sent my request for tech support to [email protected] and got a reasonably fast reply, though it took several days before they finally sent me a shipping label for me to send back the faulty control board.

Ok, so I posted a few days ago about my batch 2 S3.  At stock clocks I get a huge hash drop at 2-3 hours and one chip is showing a "-" where the "O" should be.   I contacted bitmain and they said to re-paste, which I did.    The paste seems do have done absolutely nothing.   I would rather not run it at 212 but that what it is at now, has anyone found a reproducible solution for the underperforming miners?  

I have one in the same situation, it just does not like anything higher than 212. I know there are others in the same situation. On the positive side they consume less power. I did everything possible to remove thermal problems and none help. Mine is a B1 so I would just let it run. The amount of time working on them takes away from production. If you are like me you just want to get it up to speed but sometimes you just have to let one go.

Look at my previous posts on this thread, you can follow my saga. My personal solution has been to institute scheduled restarts. I am now between 460-490 for about 3 days now and have the accepted shares to show.

Dupes are a bit high, but that's to be expected with this config.

What are you using for the restarts schedule?  It appears the problem with mine is that BOTH a hard reboot and GUI reboot are necessary to get my miner back on track.

Hey, I also have one miner that (only working at 212.5) does great on restart for 24-36 hr, averaging ~430Gh, then goes to 400 and stays there.
I would like to use the scheduled tasks trick, but there is already a string of code there (in scheduled tasks):
Code:
*/3 *  *  *  *    /usr/bin/cgminer-monitor
should a put the string like this
Code:
0 1 * * * /etc/init.d/cgminer restart
below it to do a once in 24hr (at 1am) restart or replace whatever is there already with a new string? what that does anyway: cgminer-monitor?

Corsair CX500 = $29.99 (after rebate - expires 8/11/14) currently at the Egg + 10% BTC payment discount.  Also, when available, additional instant discounts with Promo Codes (appears just below the product listing title on a week to week basis):

So! All units are hashing over 440gh (Two over 490), but only when using a cronjob to restart the cgminer service every 1/2 hour - 1hr depending on the miner.
Regardless of how long I leave any of these guys up to "stabilize", they always fall to 390-398 after 48 hours.

There's only one thing. I am noticing a rather high number of duplicate shares poolside since starting this restart routine. (surprise)
Is there a cgminer flag among the bitmain options to clear the asic of all work upon a cgminer restart? I know the A1 miners have a similar command with '--hwreset'

Restarting every 30 minutes is a bad practice.
Try replacing thermal paste grease and I think the issue will be solved.

I'm pretty aware how just how shitty it is, but unfortunately after re-pasting two units I saw a decrease in running temperatures but was still experiencing a steep drop off in hash after about 25-35 minutes. One of the units will spike back up to about 470 but never enough to average out to 440 without cgminer restarts.

I wish I could attribute this to poor labor skill on my part, but I'm just about 100% certain I don't suck at apply thermal paste. =/




what kind of thermal paste did u use ??

Ceramique


ok.. do not use AS5 thermal paste and do not place
the plate upside down like this idiot tried to do below:
http://i62.tinypic.com/k9bapy.jpg

check your heat sink is placed right way:
http://i59.tinypic.com/2l9nubs.jpg

with all those "-" it looks like you have a cooling issue on that blade.
look at your plate did you place it upside down by accident ??

Ha!  Classic.

I wonder if re-torquing the heat sink screws first was ever attempted to make sure they are snug before going through with the elaborate heat sink reseating gymnastics (and the lost precious hashing time that goes along with it).  Most of the time, that's all what's needed (never have had to reseat heat sinks to date).  That's all I did with the S3s as it was with the other ASIC devices (BFL, AsicMiner, Blue Fury, AntMiner, etc.) in the past.  That's pretty much S.O.P. upon receiving a new (or not so new Wink) ASIC device.





that first screen show a heat sink placed upside down after replacing stock thermal paste ..
if the heat sink is placed upside down then it does not make contact w the asic chips..
of course that means the asic chips will not cool well and therefore not hash well .

Quick question.  Some of you have showed using a monitor software to watch all the miners at one time.  how do I get that?

Is there a link somewhere?

Thanks
