I got my batch 7 online yesterday and the noise is horrible and I used to think S5 is noisy. Fans run over 4000rpm and blades are about 50C, air is traveling too fast, screams and resonates badly. 3 x DPS-600 powers take 1400W from wall, I tested power draw upto 1600W. Customs took 1BTC for sale tax but I have "free" electrics as garage is heated with S7 so I maybe ROI some day.
What did you really expect? One S5 with one jet blaster fan was horrible noise pollution. Then, an S7 with two of them running. The temps aren't even the "real" temps. It's just a temp sensor on the board somewhere. I would always add 10 degrees to the temp shown. 50C, thats very good. You have some leeway here. Air is too fast, yes indeed it make a lot of noise at full speed; So why are you not reducing fan speed? ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) 2 Fan is actually quieter than 2 fan because the air flow for the same noise is lower. I was expecting evolution, Bittmaintech have made these machines over two years. If You put two same size fans in a tube suction fan should bee bigger, flow rate is reduced if it isn't. Fans in S7 have the static fins which restric flow at exit, but at inlet side they reduce turbulence and make inlet air pressure higher. Exit fins are useless and make only noise. If You put hand near exit, machine don't make so much noise. If you pay almost 2000$ of a machine you shouldn't need to open it first and check if parts have fallen of. Better thermal epoxy needed or some quality control maybe? 2000$ miner shouldn't overheat and burn if it lose internet. Not GPUs hanging from wires but still not yet very matured products. you sir are wrong to say products are not very matured. The Avalon 6 is far better built then the s-7 but the better build = $$ and a bit less power efficient . The s-7 is nosiy at high fan speed so lower the fans speed to 40 or 45%. This also fixes the lost internet burn up issue. Now once the fan is at 40% you may need to drop freq to 575 to keep cool look at this s-7 using a quality psu not 3 lower end server psu's like you are using my power is 1200 watts ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FendnU8G.png&t=663&c=dWp3xeV04F5xyA)

I have three s-1's my zip code is 07731
I can pack the three in a schedule c flat rate box. So Postage is on me if you are close to NJ.
Ideal for the "free" power miner.
Please make serious offers under 90 usd for the 3 with the shipping included.
So for instance if you live in New York and offered me 80 bucks for the 3 they certainly would be yours.
If you live in New York and offer 59 bucks for the 3
I would say no.
pm's or posts are welcome.
At 25$ per S3, i'm pretty much interested, am i reading correctly, but i'm in Québec. Buying a single unit was prohibitive since one unit was 40$ shippinh, but as a bulk, the shipping might only go up to 50-60$, that might be doable. I will try to figure shipping. Montreal is in Quebec ? Send me your postal code.

AJRGale and KingColex--
Thanks for the answer. Maybe some person will donate a used S7... --scryptr
That would be great but I don't see this happening for a bit with the high cost of the S7 currently. SALVAGE-- Surely someone has a failed board with several good chips to experiment with. A donation or a tradeable item? --scryptr its all fine and good, but i see it pointless without a viable source of chips. there is not enough dead boards yet to pull and test, and there is no stock available to the public. So in the end, even if sidehack put the effort to R&D'ing a system for them, there is no source pay for his time into this development. Hate to say it, but he has to eat and sleep under a roof too. i offered one board and he just said no. Basically for your reasons. And one more it was a working s-7 so it would not make economic sense. Actually bitmaintech is so fucking short sighted about selling or should I say not selling s-7 chips to sidehack it is sad. Just sell him a thousand or two thousand chips. Make one restriction do not build a miner bigger then a th. A one th miner does not really hurt the s-7 but does allow a guy to mine in his house. How about onehundredsixty watts for one th.

Can I add a couple of R-boxes to the pool? Would only be around 65 Gh/s but every bit could help!
Let me know
you do not seem to be on the list as a stick miner. so for now the answer would be no.-- I could have missed something. I may be missing you on list so let me look a bit more. we now have a full list of 40 stick miners and a few as waiting room. please let me review the waiting list and mining list. waiting list: wiefever notabeliever AJRGale munky666 Searing

Honestly for me every miner is a little different. With the exception of the 2 batch 7's the firmware is on those factory installed and on one of them I left it at 625 MHz and it mined at the advertised 5TH, the second batch 7 at 625 was performing poorly and I was only getting around 3.8TH so I dropped the freq to 600 and then is jumped up to 5TH. The 19 others I have are batch 2 (which were advertised to run at 4.66TH at 575 TH), I flashed them with the most recent Bitmain firmware that supports the 600Mhz setting. When I had the time I found that really going through them slowly and taking my time tweaking with the frequency (and not always up) making small changes has made an incredible difference. For instance, I have some of mine set at 606MHz and some set 593Mhz. I do not think I have anything set over 625 but you can certainly try. Just make sure you are monitoring it closely when you make changes like that. I guess the whole point I am getting at is there is not perfect setting for every single miner out there. You can have rough guidelines that work for most but if you are trying to dial in your farm, then you need to play with the settings to see what works with your farm. Also keep in mind not all miners are going to perform at the highest Th rating possible. Some of my miners no matter what settings I have changed and close I think I have dialed it in, I have had to settle for 4.5Th when I should be getting 4.8 and that ok, its just the way it goes. If you are interested you can check out my mining set up here https://www.youtube.com/watch?v=K1C2LQnBr2Y If you like it, subscribe as I am always adding new content and I love audience feedback. I look at bitcoin as a group learning effort. In fact your thread has kinda of inspired me to create some kind of video addressing this very issue because I have seen this question or variations to this question come up before where people have had performance issues when dealing with several of the same type of bitmain products. They are frustrated why two or more of the exact same product do not operate the exact same way. I hope this help! This has been my experience as well! I have some running at 631 without a hitch, and some won't go above 600 before the hashrate PLUMMETS and hardware is up in the 0.x% range. Most are good around 625 frequency, but I've had to fine tune each one to optimize it, and it doesn't appear to be heat or PSU related, it's completely luck of the draw. Hardware error seems to be a good indication, if they are very low (0.00xx%) you can try bumping frequency up one step at a time, and letting it normalize for a couple hours to see if it nets you better hashrate and minimal increases in HWE. I have 2x B1's & 5x B5's, and there's no rhyme or reason as to why some will only do 600 and some are up to 631 and 5+ TH/s (maximum I'm comfortable with for my environment). Lucky for me, the lowest one out of my units does 4.8 @ 600 frequency, and best one does 5.09 @ 631, most of them do around 5TH @ 625 frequency. this unit with a evga 1600 t2 does freq 600 with 0% my best one by far. and if I use the meanwell at 12.4 volts I can do much higher ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FHBoZ8T2.png&t=663&c=-E4qLcMJtqqO6g)

yeah looks like i was way over estimating this round.. With that crazy cpl days we had i thought surely it would soar.. I found this site today:) maybe of some use to us lots of good looking graphs and data.. puts it into perspective just who it is increasing our hashrate.. http://data.bitcoinity.org/bitcoin/hashrate/6m?c=m&r=week&t=aBest Regards d57heinz I think what hurt both of our picking styles is these big up and down moves. It really looks like someone turns gear on and off > And a big piece of gear /farm/mine maybe 20-30ph. So the ups and the lows not exactly good for making predictions. There was a lot of nice 1 watt gear and .6 watt gear. To have it sit in a building complex like this story talks about is not farfetched. http://www.businessinsider.com/chinese-built-ghost-town-kilamba-angola-2012-7?op=1 BTW more then 147 blocks so far today at the 21 hour mark we should be at 126 so + 21 for the day. we are moving closer to 9% https://blockchain.info/blocksHeight 386889 (Main Chain) 2015-12-05 20:39:53 386742 (Main Chain) 2015-12-05 00:00:46 147 made should be 126 + 21

Would like to join and will wait till the next round. I'm on Kano.is pool and wonder why my stick 178 accepted 60 rejected probably means I'm too slow of a miner. Using the new Bfgminer (works great now even for avalon1) 12.42/12.24/ 9.87ghs HW:/2 running for 12 hours
somtimes I get CBM:0 Comms error <werr=1>
those are okay numbers. I will list you I think we may expand to 50 next round.

Nice to not see 10 on there. Even though it's still higher then I like 10 just is to much. Price is around 278 which is pretty good. Were making some gains there which makes me happy.
I'm sure you mean $378, right? You seem to occasionally drop $100 in your posts. Maybe you have a subconscious wish for a lower price? I have to admit that as a hobbyist hodler I'd prefer a lower price, and the corresponding lower difficulty. At least until my S7s ROI ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) I was just going to ask op if he has a weird type of dyslexia as I noticed the error. Maybe he is on a tablet they can be worse for typing.

good info 12.6 volts max is very good that makes this a decent option for the s-7 There's a Vadj pot at the bottom. The max output voltage is around 12.6V. Need to remove the screws holding the PCB to get access to it. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F8g0FQJ7.jpg&t=663&c=ytAwXyanGg9ePw)

Amen to that... Would love to know if efficiency has decreased at all at that clock speed, if you ever get a chance to measure ATW consumption!
when I used this psu with the s-7 https://www.trcelectronics.com/ecomm/pdf/rsp1500.pdfI set volts to 13 and ran both the s-7 and the avalon 6 in both cases efficiency drops a bit the s-7 is .26 on this psu at 600 clock and drifted up to .29 running at freq 631.25 my batch 1 got pretty hot and loud so I can't do long runs with fans blowing at 4200 rpm. This psu was purchased for testing the s-7 and avalon 6 for underclock not overclock. And right now under clock under volt is a no go. But I have determined this. both the s-7 and the avalon 6 should have at least 12.2 volts not 11.9 this means finksy + j4bberwock has the best units to mine the 2x 2000 units with a few volts setting are the best gear (240 volts fuck the sound). At finksy pm me when I can get one of them.I no longer tell anyone to use ATX psu with this gear. Unless you have only 120 volts power

Some Miners will be more Voltage sensitive than others. For instance the S1 & S3 use Buck Converters to generate the Core Voltage, because of this they will compensate for variances in the supply voltage & protect you from problems due to voltage.
Other Miners like the S5, S7 & Avalon6 supply the ASIC chips connected in a string (Like Christmas Tree lights) The Core Voltage is then determined by the Supply Voltage divided by the Number of Chips in the string. So now dependant on the exact supply voltage you will get a different core voltage.
That supply voltage although nominally 12V is dependant on several factors. First is the voltage it is set to with no load. Next as you load the Power Supply that voltage will often change dependant on how good the PSU is and it's ability to regulate the voltage. Third and often forgotten the wires and connectors connecting the PSU to the miner have resistance and the higher the resistance the more the voltage will drop with load.
So the bottom line is. If you play with Miners buy a Multimeter. Then you can check the voltage that is actually at the PCIe connectors. I think that many Miner problems are PSU / Voltage related, and when presented with HW errors and other unexplained problems it's one of the first things to check.
Rich
When running at freq above norm (overclocking) The s-5 the s-7 the avalon 6 all like hot psu's ie 12.1 volts not 11.9 volts . If you mine with the 3 above or a s-5+ keep that in mind. BTW of all these units only the avalon 6 tells you the input voltage so it is the only one that you do not need a meter to know.

A rollover would be fun but I must admit I want an 8.4 as I never played this game before. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) How is the prize determined? if your pick is 8.4 you get all numbers from 8.40 to 8.49 we use www.bitcoinwisdom.com as the number to match Thanks Phil, but I meant what you meant when you said: "Prize will be .36 or so." okay misunderstood. Normal prize = 0.1 We rolled over due to a miss so 0.1 + 0.1 = 0.2 and there was a side contest in which two winners of it tossed in .008 each so this contest is for 0.2 + .016 = 0.216 btc I added if we roll over we would go to 0.36 that is simply bad math or a tired 58 year guy that can't always remember info so if we roll over we go from 0.216 to 0.316 btc . My bad on the math. I can tell you this https://bitcoinwisdom.com/bitcoin/difficulty (+8.34%) >>>> You are really close to it and may win the 0.216 BTC this timeBitcoin Difficulty: 72,722,780,643 Estimated Next Difficulty: 78,787,307,274 (+8.34%) Adjust time: After 231 Blocks, About 1.5 days

Hi, I'm writting here for solve doubts about HWE% acceptable for Antminer S5. And, for example, the HWE% can going increasing and inflict a terrible damage in the miner? Other point, my miners #2 have a bad chip, 1X, and the HWE% isn't high, why? I going to attach the image here. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FSqoCEwL.png&t=663&c=38_uIgQBKs6Wmg) Good Vibes! I rather see the gui to tell your problems but it looks like 1 miner has 1 x which while not perfect is okay. note the image did not show for you because you are new. but I checked it and allowed it to show. I am not new and can do that. I rather se a two or three hour screen shot of the gui . I would like to know what psu's you use I would like to know the temps. I would like to know the psu. The fan speeds etc. but if you stay at the stats above for two or three straight days you should be fine.
