Anyone know when next batch of S9 or R4 is gona be realsed? Approximately.

Thanx!

no one does. just keep checking the thread for bitmain to reply with a release date.

Was selling a few s7's on eBay.
Turns out that there is a drop ship company in Newcastle DE that buyers out of the country send to.
At that point the item can be shipped all over the world.
Then the buyer will ask for a return or more items than were actually purchased.
So be careful with buyers with a Newcastle DE shipping address.
eBay knows about this scam and location.

good info. if the buyer asks for a return they have to pay out the ass for shipping back to you. ebay wont refund them without them sending it back. also overseas orders usually take a while to go through customs on the us side and on their end but the tracking info you have will provide everything ebay requires which is that is was delivered on xx date at the DE location. if it takes another 2-3 weeks to arrive overseas you can tell ebay it tooks them xx weeks to tell you there was an issue and dispute the return. its best to speak with a rep on the phone so you can explain it to them directly instead of trying to settle the dispute through the online dispute section because humans dont check the dispute usually....their automated system accepts just about all return requests even if you know the return is phony.

Hello people!

I recently cleaned up an Antminer S9 after several months of use. The good part is the temperature went down about 10° Celsius. The bad part is the fans are now doing an annoying whistling sound they didnīt do since it was new.  Huh

I have tried setting the fans from 60% to 95% and curiously the whistle is louder at lower fan speeds.

I remember in this tread somebody mentioned covering part of the front fan grille could reduce the whistling. I tried that and the whistle is reduced, but the board and chip temperatures rises. I also worry that's not a good solution long-term.

Could anybody share some advice about how to reduce the fan whistle without the temperatures going up?

Thanks a lot!

there is no way to do it. the grill or at the very least part of the grill has to be covered which restricts airflow which makes the temps rise. if you remove the grill the whistle will still be there too usually. your best bet is to cut a small piece of scotch tape and move it around on the grill until you find the right spot. then you cut the tape as small as possible until you use the least amount of tape to block the airflow which will reduce the impact it will have on the temps. i dont think its the grill or fan creating the noise though. the issue is the heat sinks not being on straight all the time and it makes some whistle louder than others.

I will update this post with proof of what it

http://imgur.com/a/UxHzp

Read point number 1

i for 1 am glad the warranty is 180 days now lol. idk y ne company would think a 90 day warranty is ok. then again they removed the ability to overclock the miner and lower the fan speed down without using an external controller so i guess that made them feel more comfortable with offering a 6 month warranty instead of 3? either way i welcome the 6 months warranty and hope i dont ever have to use it.

i still have my $150 in coupons that im unable to use because another batch hasnt been released and the last batch i was supposed to get an email about the date/time of the release but i got nothing. i only saw the info after they sold out and boy did they sell out fast!

Yeah, I know. And I got two of them working on all dies (ok, one die out of 8 is a bit wonky but that's fucking amazing!) The trick is if it has only one die hashing it's possible the other dies have cold-soldered themselves to the point where they don't work. It's possible to reflow but be warned: IT IS VERY EASY TO FUCK IT UP AND WIND UP WITH A DEAD UNIT. Also the line drivers were damaged on one board.

Speaking of which: I finally figured out what line drivers/buffers these KNC people used: It's this:

https://www.digikey.com/product-detail/en/fairchild-semiconductor/NC7WZ17P6X/NC7WZ17P6XCT-ND/

They are super small, and super critical: If you plug in your 10 pin header so that it goes over pins 13579 with 246810 then you will probably blow up a few of these, your cube will appear, but will never hash. It will also blow out the FPGA on your controller, so a twofer failure.

So I have now expanded what I can fix:

If your Titan has one die, I can try to get it to 3-4 dies
If your Titan comes up with no hashing but can be seen in KNCminer, I can probably fix it
If your Titan has a burned power connector I can fix it
If your Titan totally burned the board under the power connector then sigh, I can fix it.
If your controller is dead, I can fix it
If your bridgeboard is dead, I can fix it but you have to replace your Rpi too.
If your Rpi is dead, just get a new one and power it via the USB port. Lazy but works.

And as for the crystals, it's probably one of these:

https://www.digikey.com/product-detail/en/txc-corporation/7B-24.576MBBK-T/887-1898-1-ND/

But I need to measure it with the digital calipers. Note though the cross-grounds that's part of the problem with the QB BB.

C

what about the converter boards that connect the pi to the controller card?? is there a seller with reasonable prices for these?? and they let you hook a pic to the controller that support beaglebone without the middle board between them right??

im honestly genuinely currious....why are people buying these at the listed price?? Mining isnt a hobby for u me and most other folks anymore which means we need miners that make a return on the invesment you make but these numbers mean they wont make a return in a reasonable timeframe. sure avalon miners r reliable and sturdy...i have owned multiple avalon and avalon clones and can admit they r sturdy and well built. I especially love their older models that had cases made from solid aluminum and can reuse the case for other suff but i dont think its good to support a company that is clearly overcharging for their miner. If they released at the same time bitmain did then i can see the higher numbers but they released their miner after many revissions of the s9 were sold and after all that they havent lowered their price to match the difficulty increase. hell one diff increase was 10% and that jacked the roi times from 400 days to almost 510 days at cheap power prices and anyone that follows prices of miners knows avalon miners dont hold their value any better than other models.

i dont mind doing wire transfers for these miners because i have 2 business bank accounts that allow for international transfers  that arent over the top expensive but i cant justify it at these prices. in 6 months the value will be gone almost and you wont be able to reach roi with the money made from selling the miner including the btc mined with it. It can last until the end of time but if it doesnt return on your investment what is the point? this seems like more of a novelty than an actual investment. people are buying because of quality but in the mining world high quality low quantity doesnt usually = proffit. u gotta find the middle ground between the 2....and i wanna hear why others think this is a good investment. idc either way just currious and wanna understand the thinking behind these purchases a little better.

The s9 s break too easy.
My power is cheap.
I will sell them before value fully tanks. I hope!

ya i have read alot of your posts. have the temps in your shed/barn/solar powered thing (idk what to call it i just know it has multiple lvls and has solar power...not meant to offend) down now that winter is upon us? that should help your s9's run cooler for longer hopefully. I guess unless you have a specialized setup with free/cheap power these wont be worth the money. free power deff lowers the roi times.

Can anyone with a unit comment on their noise level?
I would call these only moderately loud, whereas the S7 was extremely loud. Not quiet enough to have in your bedroom but okay in another part of your house. I've never had an S9 so cannot comment, but presumably the S9 is just as bad as the S7.

depends on the version. the old version is better...the new version cycles the fans up and down up and down over and over again non stop which is worse than running them at a regular speed sound wise and cooling wise from what i have experienced. either way im sure all 3 r pretty loud.
167  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: November 28, 2016, 07:30:01 AM
Incase anyone was wondering. The S9 can be made quieter if you want to underclock it. I've got mine running at 200m pulling 430w at the wall getting 4.2Th and it's nicely located under my desk.

this only works on the old versions of the s9. on the new batches you cant control the speed of the fans or the speed of the miner unfortunately. unless u do what i mentioned in previous posts but that only works for the fan not the miner speed.
The latest firmware let's you sit the freq on firmware install... so it can be done still

so you have an autofreq s9 and when you set the freq it actually sets it and runs at that freq? because what i have seen the manual freq only works on the pre auto tune miners and doesnt apply the freq to the non auto tune boards.....
The LATEST, s9 firmware, allows you to set the operational FREQ at install.
so in theory you could set a 14th S9 to run at 9TH. and underclock it...
I have not played with this yet


hmmm well when you do please let us know because freq control would be awesome for the autotune miners.

Quick question regarding fans. If I were to change the fans out to a 3pin 120x38 fan and use a 3to4pin adaptor cable what issues would it cause? Would the fans run flat out as its only a 3pin fan?

firstly dont change the fan.

secondly yes the fan will run flat out because the controller isnt designed to control the fan speed via the output voltage...its designed to controll it via the pwm controller so the voltage being delivered will be a constant 12v and on a 3 wire fan that means running them at 100% all the time which isnt good for the fan at all. they r made to run at 100% but in short bursts not all the time. mmore than likely the 3 pin fan will not more enough air anyway unless its made to move the same amount of air as the current fans do.

in short dont swap the fans. read my post and sidehacks post about a pwm controller.
172  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: November 25, 2016, 07:55:38 AM
Oh so you just tie in the one wire. Is it simply a pot? Or is there more involved in that adjustment? I can't find the one you purchased any longer, but I'm still looking.
Thanks
The PWM signal is not analog (from a pot). It is digital Pulse Width Modulated signal, I think around 1kHz, that drives a switching circuit inside of the fan that handles the power side of the equation. The on-time vs off-time determines fans speed. Just to confuse the issues, there are 2 different schemes used... Most common one is no signal (always Lo) puts the fan at full speed in case the signal wire opens. Also seen is the reverse - no signal means slowest but usually not zero speed.

Query: What does the fan do with the blue wire disconnected? Full speed or slow?

yes when you unhook the pwm wire the fans will spin at 100% all the time.

and no a pot will not work to control the fan speeds. the device i linked has a pot on one side but the other side has the components that are controlled by the pot. without those components the pot would be useless in this situation.
173  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: November 24, 2016, 01:36:42 AM

ya no one seems to read my posts very much lol. i agree the auto tune feature isnt much of a feature. it runs boards too hard and i personally would want to control the speed. idc so much about raising it but i would at least like the aility to lower the speed but with the new firmware your unable to. my post was just to give some sort of solution to those that wanted to solve 1 of the 2 issues which is fan speed control. if it helps folks great if it doesnt great lol. at least this way they can try to get a handle on the high temps when running these auto tune miners.

I read your post, just didn't fully understand what you were getting at, It also seems like it may not be the best option, If we set them at one point and it at some point needs more, no way to get that.
A software solution that won't let them go lower then a certain speed, but still ramp up if needed would be ideal.
But I will look into those controllers.
Did they do a fine job of tricking the s9 into thinking it still had control?
As I understand it, the thing shuts down if it thinks the fans stopped running.

the 4th wire on the fan connector is the pwm wire. this is the wire the fan uses to control the fan speed. the adapter i sent allows you to control the fan speed of pwm fans. it cant handle high wattage loads thats why you would unhook the 4th wire (blue) from the fan connector and connect it to the 4th pin on thespeed controller i linked in my post. used a flathead screwdriver you can use the pot on the board to raise and lower the fan speed. i thought this was clear but wossry if this still isnt clear enough for you.

yes this method is not ideal and i even said a software method would be best but this is a solution. its to run the fans at a constant speed. you dont use this method to run them at the lowest posible speeds...this is to raise them up so the temps stay steady and dont run into the hundreds like the stock fan settings do. thats all this is good for.
174  Bitcoin / Hardware / Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order on: November 23, 2016, 05:57:52 PM
the "elephant" for home-miners is the noise, and especially the strong modulation of the fans yes, and yes it is annoying. Before setting the miners in the actual racks where the noise is no problem, we always test them in the office for a while to make sure they run fine. Right now my ears would be ringing if I wouldnt be using earplugs. and they are still annoying.

Nice of you to jump in, and still be following the thread.
but please, can we discuss the elephant in the room? wtf is with these fans
They idle so low one minute, and the next minute my neighbors can hear them.
I have no issue with noisy miners, but this seems like it's just unrequired noise.
One minute they blast at 110% the next they are cruising at 25%. than boom back up again.
If they idled Higher, at 60% maybe? they would need to spike as often, and this would help with the noise greatly.
If you read the thread, people even gave a solution to have them running more constantly. I.e. the followoing
there is a way to controll the fan speed. im sure the firmware can too they just dont want to allow that but the way im talking about requires an external device that connects to the pwm wire that sends the signal needed to spin the fan up and or down. i got a bunch of them a while ago to control the fan speed on delta fans that have 4 wires (12v, gnd, tac, pwm) and they work great. since pwm fans need the 12v power to be steady all that is needed is to hook the pwn wire from the fan connector and connect it to the little module. the module isnt made to handle tons of power through it that delta type fans use but since the 12v and gnd are still on the main controller that wont be an issue. i tested it with the pre autotune s9's and was hoping to use it with s7's when it got colder but it turns out it wasnt that loud so it wasnt needed. i can test it with the auto tune firmware s9's too but im pretty sure it will work just the same. you turn the pot on the device to raise and lower the fan speed. one would be needed for each fan and maybe 1 can run both fans im not sure. i tested it on 1 fan at a time though.

that link is super old but thats the speed controller i used with delta server fans. it only shows a pic of the top side with the pot but the underside has the components that control the fan speed. they have other versions similar with a plastic shroud over it and should work the same way. i went with these because it was a simple design that attached to the fan itself instead of having a box hanging there. im not responsible for any wrong hookups though and even though its pretty simple to do make sure your removing and hooking up the right pin....


But the cause for the so-called "elephant" is a much bigger problem with the auto-tune S9s. And that is the extremely high range of frequency distribution over the 3 cards/boards/blades in a single S9, at least for the B22-11TH/s models we have. This in turn leads to miners breaking down rather soon (in my case one miner was bye bye after less than 24h), leading to repair/delivery costs (even in this case) and downtime of the miner. So, honestly, what is worse, a strong modulation of the fan speed ==> noise levels, or that Bitmain is selling faulty products to the its customers, which break down sooner than later.

There many possible causes for the bad frequency distribution, be it the faulty automatic-tuning firmware of Bitmain of the cards which leads to this distribution, or be it the greediness to use underperforming chips on the boards. Nonetheless, it is a problem introduced by Bitmain by selling faulty machines (be it firmware or hardware) to the customers (be it on purpose or by accident).

$1500 for s9 and psu and free shipping bitcoin only
Does it every weekend on hacked accounts for three days.
Be careful
If it is too good to be true bye bye bitcoin
It's price sounds good but you are right, it mean's bye of your money. Also there is another chanse that maybe that antminers are used and that's the reason of low price. But to buy used antminer, it's risk always, even it's risk when you buy new and original. So it's always better to buy directly from bitmain and also once I bought it from aliexpress and I wasn't dissapointed,

ur right there is always a risk but when buying on paypal your always protected from sellers that dont ship or send you something you didnt order so at least the people that risk purchasing it wont get screwed out of their money.

Are the issues you guys have been seeing with the S9 related only to certain batches?  Trying to decide if it is worth the risk to buy one.  Thoughts from S9 owners?

its not so much related to certain batches. its more related to how alot of people chose to run their miner which was outside in the heat of summer and or in a tiny room at over 90 degrees room temp lol. u

I don't think this is true at all. My boards failed in a datacenter and most of the other people who reported failures are reputable miners using no different setups than they did for their S7 or A6 miners.

Its happened in most of the batches up till the most recent ones so far, failures of entire boards, needing replacement or fixing by the manufacturer or their agents (bitmainwarranty). USually it happens within the first few weeks of ownership, or if you are really unlucky on day 91 (1 day outside warranty) Smiley


idk y i have to do this but i do....i like how u quoted only part of what i said and left the last part out. just wo we are perfectly clear here is the ENTIRE comment i made:

"its not so much related to certain batches. its more related to how alot of people chose to run their miner which was outside in the heat of summer and or in a tiny room at over 90 degrees room temp lol. usually if you run them under the proper conditions you will be fine. i havent had a miner die yet *knock on wood* but some miners just fail for no good reason other than stuff failed....it happens. but the ones being abused dont fall under this category."

if you check out the second to last sentence i stated "some miners just fail for no good reason". i believe that applies most to your situation.. the first part of my comment hasnt changed though. if you look at most of the complaints about their miners not working anymore you will notice alot of them arent run in the ideal conditions. im not talkin the most perfect of conditions either...there is always wiggle room but i think even the people running the miners in these conditions can agree that they just shouldnt be run that way. we have people running them in sheds and barns outside exposed to moisture and humidity and some people have posted pics of miners caked not in fine black dust but what looks like a clogged bathtub drains worth of hair and leaves and other junk and then they come here actin like they had no idea this wasnt the right way to use their machines lol.

now im sorry yours failed. if you were in fact running them properly like you said you were then it sucks that they died and i feel for you i really do. but to say what i just said isnt true at all either means udk what ur talkin about or you havent read through the almost 150 pages of comments like i have. if you had done this you would have seen the arguments being made to justify running a miner in ambient temps of what can only be compared to as a hot ass California day and thats not including the ones where they were run outside in sheds or barns lol.  with such densely packed miners like this simply saying "i could do it before" doesnt really apply. they need to be used in controlled environments at least to a certain point.

now running them outside now isnt a good idea but even i will admit its not nearly as bad as running them outside in the summertime. there is still wear and tear being added to the miners but the temps are much lower so at least they dont run as hot anymore but its still not the ideal condition and never will be.
179  Bitcoin / Hardware / Re: Avalon A7 announced on: November 17, 2016, 02:24:06 PM
im all for "quality" but whats the point when it will take 420 days to break even at todays difficulty (its going up by 10% in the next couple of hours so that number will be higher)?? thats with .10 per kwh too which in my state its about .15. with free power it will take 215 days to break even at the current diff but not everyone has power they dont pay for so when they can beat bitmain on price AND quality then i would buy some but until then i cant justify taking up twice as much space and using a bunch of extra power supplies to power the extra miners i would be running.

im just glad bitmain came to their senses on the price of the 12th model....they jacked that price up so high even after btc prices dropped by $50. it was clear that it was a price hike based on total greed. i have a bunch of s7's i need to upgrade but the room those run in cant have the fans whirlin up and down up and down every second like the new batches do so i cant really upgrade them unfortunately....unless i wanna pay out the butthole for avalons 6th/s miner which i deff dont at those prices.
