Yes, I had lost a bunch of hash for a minute too!

Guess there was a node that went down just lost 30ph from the pool 

My experience with the two services was a little difference.  I have had 4 boards fail between 6 S9s.  The first 3 were from 2 of my earlier machines and were out of warranty, so I send them to Bitmain Warranty in Colorado.  Never heard much back for a couple weeks and when I eventually heard back from then (about 4 weeks total), they apologized send the boards back fixed for free.

My last experience was with the new repair place in LA.  Since the machine was under warranty, I had to send the whole machine.  This also took a month and it wasn't until I opened a separate support ticket that magically my machine was shipped back.

Both took 4 weeks, and cost nothing.   I guess I can't really complain. . On the other hand I did lose 2 months of hashing so it did cost lost revenue.

@NomadGroup

you need to host your images else where, imgur.com is what most people use and its free.

They will give you a link to attach to a post and Boom you're good!...lol

My experience with sending machines to Bitmain for (under warranty) repair has been very commendable.
Unfortunately, I have had to send in 4 machines up to this point. Also, I am not sending them to China. If you are in the US, you send
them to LA. They test the machine the day they receive it, confirm that it does indeed have a problem. They process it w/ China and I usually
receive a repaired machine within 3 business days. It does kinda irk me that I send in a new machine for repair and usually receive a clearly used sometimes
dirty, visible ware on the outside, machine back. However, as long as it works, I can live with that. Does Bitmain repair machines that are out of warranty?

Bitmain Warranty is a different story......

6 weeks ago I sent in 3 hashing boards for a S7. I never got notified that they received until I emailed them 2 weeks later. I have never got any kinda update about my
boards whether they have been looked at/repair/repairable/paperweights/etc. I emailed them last Friday. They responded that they have not been able to repair them
and that this week they were gonna give it another try. You can never get them on the phone, the experience just kinda makes me think that they get there stock from
people that send stuff to them and "they can't repair it", then stock shows up on their website for sale. Maybe not. Maybe they will actually email me back sometime. And if
they are unrepairable they will actually mail them back to me, only time will tell.

Anyway, that is my experience with the 2 repair services.

Now I'm gonna go do a Block dance out in the garage. I hope it helps.

Is your s5 pretty close to the window?  If yes then you should really consider buying some adapters like this;

And connect some flexible ductings like this to every miner;

And just stick them out the window or better make a window insert out of wood and cut some holes in it and stick these hoses into holes.  I'll show you how I have it done as soon as I find out how to load a picture here in the forum from my ipad.  I got couple of laptops but I barely use them, only for connecting my Ledger wallet, other than that my ipad is like my second right hand, always with me! Hehe. 

Oh, I see.  I didn't know that, although in my case I think it might still be cheaper to send to U.S since it is closer to me, that way I would save on timing but then again it all depends how much they would charge for the repair.

And guys can someone please tell me if it is possible to load pictures from ipad into this forum?  When I click the picture icon it doesn't seem to do anything beside adding a couple of IMG words to the text.  Thanks! 

BitmainWarranty repairs in the US is not covered by Bitmain's warranty.

If the S9 is within warranty, you have to send it back to Bitmain in China to (possibly) get free repairs.

If you send it to BitmainWarranty, you have to pay no matter what, unless you bought it from BitmainWarranty.

...and the S7s sound like the flight line at Da Nang... 

It will be a lot nosier. The s9 has a much higher pitch than the s7's.

Thats great, very useful information. Much appreciated. Its not put me off, but I do have a spare 3kw UPS system laying about, I'll run it through that, along with a good PSU. My room temp is around 27deg C here. Windows open trying to keep the office cool, and that just with 1 x S5, lol. Going to be a different climate with the S9, good job its winter coming.

I've had my 8 s9's for about 6 months now so far I've had to change 1 control board and from what it looks a second one will be going out soon as well as 1 hashing board that I have to send for repair now and not to mention that 2 or 3 ( don't remember) s9's have completely failed on me , that was within the guarantee time so I got them repaired for free but at the same time I had to pay around $70 to send each unit back by EMS and wait for about a month and a half to get it back.  It took them around 2-3 weeks just to confirm that they've received them. Now that they have a repair center in the U.S I'm sure that things might be faster but I don't know.


In my case from what it looks the control boards keep going out when the electricity keeps getting shut off very often or because of spikes, I think it can even brake just from some static electricity so I wouldn't recommend you touching it too much.  It is important to have a good power supply so don't be stingy and get a good one right away or it will cost you more later and having an extra power supply is a good idea as well as having an extra control board so that if one of these 2 brake you won't loose BTC, waiting or even looking for them.  Waiting for some parts or for your unit to get repaired is the worst thing!  I hope I didn't discourage you too much but it is the reality.  I keep my miners as cool as I can but where I'm located even with a special cooling system I can only have the room temp at around 27c and max I try not to get it go beyond 31-32c and I can tell you that at 27c they seem to work a lot more stable and even put out more hash.  

Hope that helped! Happy mining!  

Sorry Kano, figured since i was a simi active member of the pool one post wasn't to bad. Just figured the pool would have gear laying around. With all the talk of buying the s9's and Avalons. All the hash I get is comming to the pool so figured it was a win win scenario. Edited my comment as well to only send pm's and not post in the thread.

... and please discuss the buying and selling in PM
(yeah the first post requesting the PMs is ok)

Any one got any used gear laying around they are looking to get rid of? My Boss said I could bring my miners to work so trying to fill up the space. Since it is a wind farm kinda cool powering the miners by the wind! PM me instead of posting it to the thread please as advised by kano.

Are S9's prone to failing? what tends to go wrong? what causes it? I guess heat wont help with the life. I have ordered a new S9 and reading this post has got me wondering, when is it likely to go wrong? will it last a year? or is it more like 6 months?

I hear you man!  It can get annoying and pretty expensive keeping the s9's in tip top shape!  I'm glad that I got a couple control boards now so that I won't have to wait if another one goes out. I haven't got time to send mine off yet, besides it still puts out like 650mh with the 48 chips still doing some work, although I would think that it should put out more than that because there are 63 chips in total.  I'll try to send it before the end of the week for repair and let you know how it goes.  Good luck and Mine On!

Yeah, I have t got my 14th's yet.  Should be getting them around 15 of October .  13.5 is the only ones I have too.

Are the 14 TH/s shipped yet? Got a 13.5 TH/s S9 earlier this month, and reality is more like 13.737 TH/s.

What kind of hashrate have you guys been getting out of the S9 14TH have you found them to be +/- that by much?
