Bitmain will be releasing S15 and T15 on 8/11/2018

[digital$]

know this thread is relevant to S15/T15...but isnt the S11 based on newer chipset(7nm) as well?

I was under the impression it was as well, however I cannot find any info on the Bitmain website which lends any fact to that impression. The blog/PR post from BM about miners featuring the new 7nm chipset only mentions the S15 and the T15. The efficiencies of the S15 and T15 are a significant jump from the S11. The S11 has 252 chips on 3 boards while the S15 and T15 have 288 on 4 boards and 180 on 3, respectively.

The above factors lead me to believe that the S11 is in fact using 16nm chips and was probably their "improved" S9 they intended to release had they not been experiencing such financial difficulty.

thanks sarcheer...seems you could be right...ie 16nm chip

S15 - 28TH
220V / Ambient 17 degrees C

3 Days on Nicehash, so far so good.

Power Supply fans ruined sound improvement from lower miner fans speed.
Very high pitch noise.

Our s15 adventure continues. This morning we shipped the (2) S15's that failed on 240v to the CA repair depot. This afternoon 10 more S15's arrived from BitMain. We put them on the 208v rack at the office. Of the 10, 7 work perfectly and 3 will not show up on our network despite all efforts and troubleshooting. Can't figure it out. So now I have 13 S15's running, 2 going back for PSU, and 3 that boot up but won't communicate with the network. I wish I could get ahold of a couple of spare PSU's and controllers for these guys. They aren't selling S15 parts yet, are they?

Are you getting both blinky lights from the Ethernet ports?

One thing, which I assumed was because I swapped an Ethernet cable from an A4+ to the T15, is that when I powered up the T15 is it stole the IP address from the A4+. Given this may not be an isolated incident caused by my switch, are you using static IP’s or dhcp? If DHCP, you may want to move all the existing miners to static IP’s and see if the missing miners start showing up.

Definitely have normal connectivity lights. Machines boot as normal, all lights normal, but cycle due to not having a network connection. When we plug them into the connections of working machines, they do not come up. All the miners on the network are static IP, but we have a DHCP range set aside on the router for new machines. We boot them DHCP and then assign static IP's.  Power cycling and resetting the machines does not help. Switching PDU, power cables, and NIC cables doesn't help. Units do not show up in our routers control panel of connected devices. I thought perhaps they had shipped us units that had already been assigned static IP's, but a factory reset would fix that. I though maybe the NIC's were being finicky with our gigabit switches, so I put them on a 10/100 switch and also plugged them directly into the router. No joy. Not sure what the problem is, but if the controllers aren't bad we'll figure it out.

[philipma1957]

lets say  you do a sub net.

your main router is say  192.168.0.1-256

add a cheap  router  that is 192.168.1.1-256

so modem >>>> main router >>>>> cheap subnet router >>>>> attach 1 bad miner attach 1 pc  search with advanced ip or angry ip   see if it shows.

I had issues with early model s-9's  sound like this issue.

So  2 dead psu's
and 3 weird ip's out of 20 units correct?

To late now but the s15's in your case should have  been m10's

My 4 m10's = flawless  they do 59-60 watts  a th at  low setting about 20.5th

are you usa based?

If its only diagnosing, you can connect a pc directly to the miner or via an isolated router and scan.
If its using dhcp, check its log and immediately catch any assigned IP.

That is: Take a router with dhcp enabled, don't connect it to internet or anything, just a PC (or smarphone) to catch is web ui, and the miner and see if it gets an ip assigned. Else, do the port scan from the pc itself.

There is also a third option more advanced involving serial port console access via the lan port of the miner, I think the S9s can do it, perhaps the S15 can as well?

[fanatic26_]

Each of my technicians is armed with a $30 cheapo netgear router because their base firmware will find any IP that is connected via ethernet even if it is not able to communicate with the unit. We have ffound some really strange network settings on machines this way.

An IP reporter factory reset should be all you need to get them back up and running unless you got a batch with corrupted controller firmware from the factory or something

i made a complete guide on how to troubleshoot/fix miners that run but do not show on the network.

I got the shipping notice today.

I have not given them any KYC data (passport etc.) they have been asking,
yet still I managed to get my order through.

I paid via bank transfer.

[philipma1957]

KYC  
they have my home  address  
they have my home phone
they have my Social Security Number
they have a copy of my drivers license

my name is rare so rare  that I have never found any one in the world with my name going back to 1900.
lastly they have sent 50 packages to me since 2013

that is enough for KYC.

I placed an order but did not pay and I think they would have shipped to me.

I am considering buying a T15 maybe a S11  I will hold some money aside for  a S15  from someone you and I both know well.

[minefarmbuy]

Yea, I don't think Bitmain is going to be too picky right now with sales.

[sarcheer]

Given this is my first all-new Bitmain (BM) product, if you exclude the S7-LN because it wasn't using new chips, I'm in the strange position of hoping BM stays around so they can properly support my investment. Since getting into mining in 2016 and subsequently learning of BM's bad actions this is the first time I've felt this way haha.

Maybe I'll settle with my conscience by hoping they keep operating but on a much smaller scale?

To make it clear why I am sharing these thoughts in relation to this thread, I've noticed that someone in this thread with a T15 that shipped after mine is on firmware dated December 29th, whereas the FW on my T15 is dated December 18th, which is also the latest officially listed FW from BM. Why would they ship the next batch with newer firmware and not list that fw for download? Are the batches different in terms of hardware? If they're different, why not give them a distinct subgroup and list that different machine's FW on the support page?

Which brings me to why I worry: are things at BM so bad that the chaos in the C-suite is affecting decisions regarding FW releases and support? They've released 3 new ASICS with integrated PSU's without offering any way to purchase the PSU (APW8) on its own, let alone share the specs on the PSU so we can be informed on our machines and ensure they're being run in the proper environment.

[fanatic26_]

fanatic26 usually has a lot of gear running.

Unfortunately I was only able to get my hands on T15s out of the first batch, so I have nothing to report on the S15 as of yet.

Yep, Northern Virginia. We have 8.4cent power on an annual contract with the PoCo here.

So, update. we got 2 more S15's in today. These are 2 of the 27TH models. Put them on the rack and they came right up on the network. So for the 3 that were giving us trouble, I took a laptop and a little VPN router that I have and direct connected each unit to the laptop via the router, then ran WireShark and found the IP the S15 was broadcasting. That got me in, and I programmed a static IP to each S15, reconnected, and they came up just fine on our regular LAN. Not sure what the issue with getting a DHCP assignment is for these units (they are running the same firmware versions as other units that worked fine to begin with). In any case, have 18 on the rack now running 100%. The two units that had the PSU problem at 240v already went back to bitmain for warranty repair.

Onward and upward.

Maybe your dhcp server is having trouble? That's one more reason i would recommend to set networking manually in all miners. Perhaps the only moment you'd need dhcp is when its brand new and you need to log in to configure it the first time into a proper manually set address, like you just did

[philipma1957]

yeah it could be
a shitty switch
a crappy router
a bad wire

may not be the s15's

Do you use fios?

I just got back from a 60 rig build out and fios is a pleasure to work with compared to cablevision/optimum/altice

Fios seems to always do Dhcp up the line   ie
1.1
1.2
1.3
1.4
1.5
right to 1.256  Super fast to search it with angry ip, advanced ip etc  please to do a build out if it is Fios served.

I'm not sure. We have a Cisco router that is up to date and latest firmware. We have 36 Z Mini's and at one time 104 S9's of every generation running on it, plus maybe 20 odd computers and devices around the office. We always assign static IPs to the miners, but allow a pool of 50 DHCP addresses for miner bootup and for the other devices that don't need assignments and for wireless devices. Never had a single problem before. We tried swapping cables and even direct connection to the router past the switches. I did open up a ticket with Bitmain support and she said it could have something to do with the way the controllers were flashed. The three units we had trouble with do have the black label around the network port and control panel, and the others do not. I'm not sure if there are any differences in controller hardware, but at Bitmains suggestion we did swap a controller from a working machine to a non-working one and the machine worked fine with the other controller.

To late now but the s15's in your case should have  been m10's

The last batch if 10 S15's that we acquired was during that little blip when Bitmain was selling them for $1050. Between that and the coupons we had, it paid for the tariff and shipping. The M10 looks like a good machine but @ 65w/TH the efficiency is too low. We're planning to deploy a total of 36 S15 by the end if Jan and run them full power the rest of the winter. That will give us 1PH. Then change them over to LPM starting in May when we start to have cooling challenges. Our mining room should be able to keep up with the heat very well with 36 machines running 850w ea + the Mini's, and we will be mining at a more efficient ratio during the May-Oct when our PoCo increases our electric rates slightly. In order for us to keep our contract rate with the PoCo we have to draw at least 60KVa 24/7, and in July I want to renew that contract for one more year. We subsidize the electric cost for the mining operation so this will make that more manageable and I'm hoping this last equipment upgrade will keep us mining until the halving. Can't really see beyond that, but I don't think there will be anymore new form factors or revolutionary new increases in efficiency in the next 18 months, so this is what we came up with to keep us mining for one more generation of gear. We can support up to 80 S15's on the current rack (we have total capacity of 150KVa), and our power cost goes down the more we use, so if the gear gets cheaper later in the year we can add more capacity if conditions look favorable. We've been mining since the S5's, so this will be the fourth cycle of gear we've gone through.

Also, I would like to give a hat tip to BitMain. They received the first warranty repair miner (one of our S15's that failed on 240v) in CA on Wednesday and dispatched a replacement unit from Shenzen this morning, it's due to arrive UPS on Monday. So about 10 days turn around from VA. Never thought I'd ever say that.
