Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

[Miasma]

BitMain, there's something seriously wrong with your S2s. When are you going to release firmware to improve their performance 

I have 16 S2s and they all stop hashing several times a day. I have to turn their power off and on to get them to restart. Reboot does not work. I've replaced the underpowered EnerMax PSUs with Corsair AX1200 PSUs so that's not it. You also released them with a ridiculously high queue of 8192 causing huge discards and an api-allow W:0/0 giving hackers easy access.

Is the S2 so unreliable that it dies in just a few months 

Are you going to abandon your existing customers or support their purchases

I have 5 S2 and they run 24 x 7 and have never stopped.  I have updated to the latest firmware.  Why do you not call there support in Denver Co there great, instead of flaming them on a public form.

+1 classy
Too bad you can't rep on here. I would add one for that.

I also have 5 S2 machines that have always ran perfect since day 1. I got them when they came out and they are still running great.

I would say you have some other issue.

No Offense.

Bitmain,

Please provide at least product dimensions for S4!! This is key for rack planning purposes!!!  Thanks,

Yes please.

I wonder what be the S5 and when would it be released.

S5...

I have a batch 2 S2 that has been mining since 2014-04-17. I replaced the PSU with a Corsair AX1200i, other than that I'm happy with the unit. Rock solid, never goes down.

Since an S2 draws about 1kW, your farm is producing about 16kW of heat. That's a lot of heat, and I suspect that is the problem.

What temperatures are your S2s running at? Sounds like they are overheating and shutting down. Constantly having to restart them is no fun, and also doesn't solve the problem. The only way to fix this is to get better cooling (more airflow / better heat extraction / etc), or break the farm into different locations.

The good news is that your S2s will shut themselves down due to thermal limits before any damage is done. Once you improve the cooling, all your units will be rock-solid. Try this test: take one trouble unit - one that needs rebooting several times a day - and put it in a different location all by itself (with great cooling / ventilation). Take it home, or put it in a totally different room on the other side of the building, or another building, or something. If it still needs rebooting then cooling isn't your problem. But I'm 99% sure cooling is the problem. It's the major problem of any miner with a big enough farm.

Can someone recommend a temporary fan replacement, I received an S3+ today but one of the fans is DOA, it worked a bit but died shortly afterwards. I currently have it swapped out for a PWM 120mm from a spare liquid cooling unit I have lying around, but it isn't as fast and not nearly as much airflow as the ones it comes with. Easy to tell, as RPM on replacement is max around 1200-1300, and the temperatures are a few degrees up over norm at stock speed vs my units on overclock that are running cooler.
I have contacted Bitmain, I'm sure they will reply Monday. But in the meantime I need to keep the unit running but I don't want to overclock it with this current temp replacement.

I have suitable fans for the miners. I can send it to you for 20 euros (this includes the postal costs in registered mail) shipped from Portugal. Cant make less because postal services here are very good ripping ou rmoney. Send me a message if interested and i send you the picks of what i have. Thank you.

[00pmac00]

While I appreciate it, I would likely have a replacement from Bitmain by the time something you ship arrives since they likely use Currier from what I have read. I was more looking for a brand/model that I could pick up locally at a local computer speciality store, or amazon.ca for example so I could have one for Monday or Tuesday while I deal with the RMA or whatever the process Bitmain uses, to confirm everything, prior to replacing.

But thank you for the offer, and I sympathize with the high postage, Canada charge ridiculous rates as well for postage of anything from a small parcel and up. To add tracking to a letter, it's like 15$ extra, USA add tracking to a letter, for under a buck I think.

Ive got 3 batch 8 s3:s, hw error rate with those are 10X versus batch 5 or 6. Is it the firmware, any ideas? It isnt still too high but i wonder whats causing this..

Batch 8   18h 14m 22s   hwerrors  1534   

Batch 6   1day 07h 14m 22s   hwerrors  133

I was getting a ridiculous amount of HW errors last 24 hours on one blade, at one pool I was mucking with (what a dud pool, 3 days and still no confirmed payouts for BTC) anyway, i had the miner do 2 different pools balanced setting, 1 blade each, when I switched it to just a single pool and used the failover method my errors went to 0.00% that is with S3+ B8

[tripppn]

Any one get B9 tracking numbers yet?

Awesome perfect thank you ordered 2. Local as well, never realised they were Canadian. Depending how they perform, I may order more for my water cooling setup for my 240mm Rad. Specs are very good if they are accurate.

Small pool by any chance? No payment, probably because the pool didn't find a block in those three days.

Yes.  However when I plug it in to the UPS site, it tells me it's created, nothing else.  so I'm guessing I'll get it mid next week.

Has over 1000TH (deliberately vague, because its not a bash on them), blocks were going, they had found blocks. They ran shifts, but shifts I think were too long IMHO, and you get paid on/after 10 complete shifts
I'm somewhat fuzzy on their whole method, but no matter, I won't mention the name, the support I received was quick thorough and friendly, so I'm not bashing, just not one I am interested in continuing with.

You obviously didn't understand how that pool payout system works. You may well have a balance waiting for you to set an automatic payout level as well as the amount, or to initiate a manual payout yourself. With a full understanding of what constitutes a free withdrawal or fee incurred.
