Ya gotta admit it is nice having the OpenWRT real-time graphs to see actual data rates and where the connections are pointed at.
Status > Realtime Graphs > Traffic > ETH0
Pretty amazing how low the actual speeds are

I really missed those when Bitmain left OpenWRT and started using their knock off of  CGminer. Think the S4's were the last to use it?

Fewer errors for the most part, and more reliable.  Some of those s9's are horrific on their reliability.  

And others refuse to die. Still have my only Batch-1, 2x batch-3's and a batch-5 along with a slew of others up to batch-25. When BM stopped accepting BTC I moved to Avalons and have not looked back since.

Think the earliest s9 that has had even a fan die is a batch-9. After that  batch- several hash board faliures and 2 fans, etc. Probably 1/2 of the s9's I have after batch 11 have been retired and replaced with the Avalons, the others get donor boards and controllers from the retired ones as-needed.

As for

Somehow I've been around for half a year and am just hearing that Antminers don't need a RPi to control it... Mind = Boom

That is/was their only nice thing. Pure plug&Play aside from just needing to enter user & pool info. However BM software is not exactly Open Source. Ja it *is* out there but...

That's funny...I never noticed before but batch 9 is where my S9 problems started.  I have a couple of earlier batches that are still running fine but from batch 9 on I've had all kinds of problems.  I have 2 of the 13.5TH/s models from February that are giving me problems now.

I'm so glad that I started buying 841s after that...I have a couple of 721s and I should have stuck to Avalon's from that point.

+1 on the Avalons....although it took me awhile to figure out that [censored] raspberry pi!   That was one thing that the antminers had better IMO (but you had to do it for each machine).

Well the S9s have a controller on top.
bitmain copied the software in it from Canaan (it's open source) then modified it a little over the years.
But basically most of the software in the bitmain controller is from Canaan or modified from Canaan
Though, the nvram in the S9s controller is cheap and nasty - although not much is written on the nvram, it fails on rare occasions and you have to replace the S9 controller if you need to change any settings.
Most people with lotsa S9s keep spare controllers.

Yeah my four s9's are a-ok...I had one board die right off the bat on one of them (but could have been a bad PSU problem)...but the rest have been fine.  They're in a data center so don't have to worry about heat or exhaust issues too.

[delicin33]

the good unicorn is the first batch of T9. I have few and since running non stop. 2 of them once made 183 days straight.

So is the T9+ more reliable than S9? It is cheaper per TH for expansion and faster ROI at current prices?

Yeah I think it's the sweet spot for Bitmain in reliability...has less chips for less hash rate, but runs smoother. 

Not sure I agree.  Feels more like marketing to me.  Both of my original T9s died within weeks, although their replacements have been stable.

My 4 x T9+  , 2 hash without any problem since delivered, 2 lost half of the hashing power on day one, in fact within 30 minutes after power on   sent one of the T9+ to HK 5 weeks ago and haven't have any update since

I have received returns from HK within 2 weeks from verification to delivery.

Pretty swift at times and I was surprised myself.

And coorespondingly, each antminer requires its own ethernet port on a switch, ethernet cable, etc.  Not a biggie if you just have a few, significant if you have dozens or more.  Each antimer will also require its own Awesome Miner license (e.g. 1 used per miner), where you can leverage 1 for up to 20 Avalons.

@kano, would it require a lot of effort to cache our 2FA codes for say 30 days? I love having two factor to protect my account, but it is a bit of a pain to enter it every time.

Just curious.

No - it's 30 seconds and only works once.

30 days defeats the point of 2FA since it means if anyone hacked you with a key logger, they can login to your account ... for 30 days.
As it is - no one can do that.
They have to hack 2 things, your password and your 2FA device app and get the Secret Key.
Makes it a lot less likely.

Edit: and anyone guessing the 2FA number ... well 1million attempts at 30 seconds each will take a while even if they got lucky and did it in 1% - 10,000 x 30 seconds is 3.5 days - though you'd be banned long before that
... and then they'd have to guess the 2FA number again after they got in, to change anything, coz the secret key is certainly too big to try and guess.

Want to thank NotFuzzyWarm for the pool advice since I'm just trying to get back in the game.  Looking for some advice on where you guys are colocating since current calculations are around $0.11/kwh which probably means I'll be taking a loss on running 5 x S9's.  I've checked quotecolo so want to see what you guys are doing in terms of loss/profit.

Keep us posted on how you do.  I'm actually surprised you can get $0.11/kwh (~$90/month) for 5.  I would have thought it would be more expensive.

I use to run (8) in my basement.  What is your local home power cost?
