Thank you for the suggestions! will pass these on to the engineers. (these changes unfortunately don't happen overnight tho...  ) S5 firmware is being tested tonight, estimated to be online tomorrow or the following day.
will this address the PWM functions of the fan? Would be nice to see a way to manually set the fan, or at least to set a temperature target (at stock, temperatures seem to be targeting 50C or less - setting that to 55C or 60C would drastically reduce the fan speed/noise) |

That is the wrong number.... but if that works for you, keep it that value!!! Over Clocking will void your warranty on the unit, please be careful Thanks for the response, but for some reason our hosting guy suggested to put /8192+8192 in miner settings. Will change it to +2050 now. The stats i posted above are from control panel. About connecting to BTCGUILD, i will soon do it and let you know the results. About frequency, changing it to 212.5mhz with default 725volt is showing 2100ghs avg but hw errors seem to be more but the % is negligible though. I doubt if the miners power consumption increases by changing the frequency but not the volts, any idea on this? Please try setting the pool side DIFF to 2048 or +2050 You can try connecting to BTCGUILD.COM and see if x goes away or hashrate goes up to where it should. The hashrate you see on the control panel and the poolside may varies due to many different factors. Our guarantee is the machine side hashing rate Thank you! I am running 3 s4's since 3 weeks and have few doubts to be clarified by any experienced users. Our machines are hosted somewhere else. In the beginning hashrate was very unstable and after upgrading to latest firmware, they became lil stable. I use p2pool. -what does hard reset mean? In-detail please? -1 of our miner has lower hash rates with 1 or 2 'x' asics failing always.After running it for sometime x starts appearing. Contacted bitmain and they said to test each blade and we did all troubleshooting stuff and they worked fine when connected to separate blades. Again after connecting all, 1 'x' appeared and hashrate is slow after 10hours compared to others. For example on p2pool with default 200mhz,725v on p2pool with pseudo,actual difficulty set to /8192+8192, hash rates are as folllows after running them for 6days : miner 1 : 1970gh miner 2 : 1965gh miner 3 : 1850gh ( which has asics failing issue) All above stats are from antminer panel and p2pool graphs shows a different story. All 3miners work with same worker. deadhashrate overall for 3 miners on pool is 270gh. shall i set difficulty to 4096 for a lower dead hash rate or is it something to do with pool? - I am planning to overclock the frequency to 212.5mhz on 725voltage. Will that work or any consequences? I have seen people doing 225mhz with 725volt. comments are appreciated. Thanks  |

if the PSU is showing the red LED, please contact the warranty service!!!
Need the original Bitmaintech.com purchase Confirmation Page
Thank you!

@sloopy,
PM Sent.
If your PSU is showing Yellow LED light, then the PSU is not functioning. Please follow the RMA process in the PM.
Thank you!

As always Bitmain Antminer price changes frequently based on the shipping dates and sometimes based on the quantity discount (bulk), price per miner may differ by orders. To be fair to each customer, instead of a blanket discount coupons used in the past, in S5, it is calculated per customer to be fair, so the customers who paid more may have received higher value discount coupons to customers from most recent purchase with lower price may have received a less value coupon. Bitmain, why are the coupons different amounts to different people?

THANK YOU!!!!!!   Here's a quick binary for the S5 based on bitmain's existing code which will ignore any queue parameter, not discard stales, should be able to ramp up smoothly if you find yourself on a very low diff pool, and use a little less CPU: http://ck.kolivas.org/apps/cgminer/antminer/s5/4.9.0-150105/cgminerBinaries will only be temporary so will not survive a machine reboot. The following will change the cgminer binary for you (set the appropriate IP address), the default root password is "admin": ssh 192.168.1.x -l root
cd /tmp
wget http://ck.kolivas.org/apps/cgminer/antminer/s5/4.9.0-150105/cgminer
chmod +x cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
cp cgminer /usr/bin
/etc/init.d/cgminer.sh restart
There should be a more comprehensive merge in the future into mainline cgminer, hopefully by Kano. Bitmaintech has provided us both with S5s to support cgminer development. |

Thank you!! By the way, lucky you with BFL Gear!!! Great to see those pictures! (Want one of them... yes i know it is more pricy when it comes to $/GH but it would be a cool item to have for a display in the future) Why bother advertising the scum bags that are bfl! I suppose it shows how wank their product is and it costs twice the price haha.
I don't trust nasty as far as I could spit, he sticks up for bfl far too much.
I'm not sticking up for BFL in any way. I have Monarchs, so I posted the data in comparison. The data shows that Monarchs are inefficient and overpriced compared to their competitors. BFL owes me a ton of money and screwed me royally. Don't confuse me owning a Monarch and posting the data for people to be able to access from a trusted 3rd party with me sticking up for BFL. I will never send BFL or any organization that conspires with them a single cent of mine for as long as I live. I advise that everyone else do the same. How is that sticking up for BFL? Bitmain on the other hand has proven once again they are able to produce and ship a top tier product without pre-orders. Kudos to them. |

Mining gears are not like Pentium or AMD or xion servers, they do need baby sitting to make sure they run at optimum condition and time to time, you have to power cycle. When you see sign of problems, fix them and intervene before further damages are done!!! If you travel a lot, and want to make sure your mining operation at home is taking place, may want to have some webcam, networkable smoke detectors (heat sensors) and networkable PDU and VPN to access your miner's web control panel for the safe operation! Another board stopped today. Down to 2.6GH

Please power on the S3 and let it run for at least 3 minutes! Then please find a little hole next to the network port (right hand side) Use a paperclip or cellphone Sim card ejector Pin (or similer) to push a little knob inside that hole in the below picture and hold it for at least 5 - 10 seconds. Let it go, and wait for 3 minutes, and power it off. Please wait for another 30 seconds, then power it back on and it should be reset to 192.168.1.99 IP and all should be the factory reset condition  How to?

@MasterRadix, Please PM us to expedite C1 fan warranty process. Please include the original order info from bitmaintech.com Thank you! PSA:For warranty/RMA issues, please contact BitmainWarranty via PM with your Bitmaintech.com order ID info! or if you don't want to transmit purchase data via PM, please request communication via email. I had an issue with two of the 3 fans of the C1 liquid cooling set. The said they would only send me new ones if I buy a new miner from them.
I replied that I get the miner cheaper from ProTact (and they give me 12 months of warranty! ) and if they could send me the fans. No answer until then.
I'll wait a few days before opening a thread.

Warranty on Bitmain Product is for defective parts exchange only. Does NOT entitle the user the new unit for replacement, the parts replacement to a new parts is the most common process. (Any demands of new units or parts without returning the claimed defective units/parts will be declined automatically)
Example, send in partially hashing unit, turns out to be the control PCB, and 2 hashing PCB passes the test, then the control PCB be replaced to a new parts, unit be tested for a few hours max, then head to customer's way.
Average processing time, the same day we receive it, it goes out the door to the customers.
On busy day, the following day, it will go out the door.
For special cases, where the miner works fine on initial boot, but claims it reduces the hash rate 10 hours or a few days later, then it will be tested for the claimed duration, then if we could recreate the issue, the replacement be send to you at that time. (Customers are usually given an option to go though this test or not)
more than likely if you speak with the techs on the phone, the techs will find the most suitable process for you and they can make exceptions for case by case.

Just an estimated number. not any specific brands or anything. Also, please consider acquiring some hardware at the very last minutes with quantity can surge the material price. Should have said per unit... Just gathering feedbacks for the future consideration. Home Miner, warehouse miners, and Farm miners may have different needs and wants. Trying to listen rather than here it is approach! what would be the ROI Expectation?
Would you rather pay $15-$20 extra per fan or "doesn't matter the noise or heat but has to ROI" model?
Something is off with your estimate, are you telling me that you would pay the same as retail for a mass order of fans from a OEM order? |

Humor is a must okay! I don't think he really means to hope our hardware to catch on fire! We know he is not that evil! Good group of guys over there, too!! He has a bitter experience with that already... Bitcoin World is evolving so fast and most of us play works 24/7 non-stop with naps in between with super charged coffee or caffeine loaded drinks, we have to have humor and be positive to stay healthier YOSHI from Bitmain *normally support staffs are monitoring this account... ... if they have spontaneous combustion issues with the S5 ...
One can only hope Dude. Not cool. As long as BitcoinWarranty / Yoshi are taking it with Humor (and they do), it's ok. |

Hum!!! Great info for under clocked condition. Thank you for the status page screenshot.
Picture is good

now you have seen the S5 naked From the consumer point of view, what would you expect from S5 or wish for? (Not including lower price...) Would you rather pay $15-20 more on quieter fans (same hashing power but better fan or fans? Would you please make sure all 4 PCI-E power cords are connected to the miner from 1 PSU?
Yes they were. And I've updated the original post to say a reboot seemed to have solved the issue. Thanks for the concern. Both units appear to be operating as expected, just not as quiet as hoped for and not a clear choice over the SP20 so far. |
