You mean 16nm here, 14nm bitcoin mining asic chips do not exist as far as anyone in the public knows.  But otherwise you are right about everything else you say here in my estimation.  Actually now that I think on it I vaguely recall someone suggesting they were going to skip 14 and work on a 10nm design (maybe bitfury?) but even if true it would be years away right now.  I think we have at least another year of 16nm as king and probably more like a minimum of 2 years.  But the competition could increase if a viable miner with bitfury chips drops (like lighteningasic) or canaan releases something with 16nm.

I believe it runs, but so far, from what I have seen reported, it doesn't actually make them autotune at all like the new ones do.

EDIT: Batch 19 saying sold out on the website already.

Didn't the original autotune firmware tune each chip?  The logs I saw posted for it looked like it did.  I haven't used any of those firmwares and my miners are all early batches now so haven't tested any of them.  I did mention the idea of mixing and matching boards based on performance back when I got my first S9 (batch 3).  That first S9 has a single bad board so I am quite certain the other two boards would even OC without a problem but that one board can't even handle stock freq.

EDIT:  I was actually hoping that one of the newer autotune firmwares would work on old miners so I could autotune that one and get a higher freq on the good boards.

That's super helpful to know.  Thanks.  I was using multibit hd in this case but it was confirmed already so all good.  I also use a variety of different wallets but usually use the multibit wallet for my miner purchases.



Yeah it would be nice if you could at least increase it some.  I was running my early batches at 90% all summer.  I have them decreased to 80% now though.

On the bright side, the network backlog is about a third of what it was yesterday so if BTC can refrain from going up another $30 today then maybe that backlog can get worked out and my transaction will get picked up.

EDIT: Well what do you know it got picked up already.  So less than 3 hours total.

Unfortunately my transaction with a fee of 0.000248 which comes out to 0.00030392 per kb has been skipped over for at least the last 10 blocks.  I decided to bite the bullet and upgrade my last S7 to an S9 but I forgot to increase my default fee on my wallet.  Normally I am not overly concerned by superfast confirmations but in the past I have always tried to make sure my payments for antminers confirm quickly.  Not sure what they will do if it take more than 24 hours to confirm.

Did it set different freq for different boards?

52 chips per board and 104 chips per miner then.  Do we have accurate stats on the chips to work out hashrate and wattage?

I am curious if any of these newer autotune firmwares have actually worked to autotune the older model miners.  So far from all of the posts I have seen, installing the new firmwares on older miners does not actually get them to autotune at all.

I remember some talk of a pencil mod back on one of the real early model antminers but I never did check it out so I am not sure what it is.  But let me see if I understand you, are you saying that drawing on the back of the R10 resistor with a pencil will increase the voltage of the chain and can help with hashboards that don't perform well at higher freq?  Does the graphite from the pencil conduct some small amount of charge across the resistor?  Also you are saying to be careful about it but having never done anything like this, what does a mark that would have a small effect even look like?

I am not sure where on the hashboard this is either, by any chance can you see this stuff without removing a fan?

If you have a 650 batch then you probably could. I have a 600 batch miner running at 606 without a problem. Just keep in mind that the S9's in general are known for a high failure rate so you are taking a bit of a risk.

These guys are in over their heads trying to run this pool.  I don't think they have the skills necessary to be honest.  Trying to make sense of the earnings vs payouts is impossible.

Did you try the reset button?  I have never tried it but someone gave suggestions on how to use in the main S9 thread recently.  It was something like, disconnect all the hashboards from power and from the control board, boot it up, hold the reset button for more than 10 seconds, let it reboot and wait 20 minutes.  Go look for the exact directions though because I may be getting it wrong.

So is that a raspberry pi in the controller unit there?  And is it 4 PCIe connectors per mining unit (8 total)? 

Can people share the file names of any firmwares they have downloaded please?  I am interested to know what versions exist.  I am aware of these:

If you are a windows person then winscp is an easy option to connect to the miner and transfer files.

Do you know an upload site I can use without registering for an account?  I was going to put it on mega but they require registration. 

I got that same Russian email a while back.  I had a repair maybe in June or July or something, and the email was regarding that.  I believe all it is saying is that the warranty on the repair work is ending.

Considering how long this autotune stuff takes, it would make a lot more sense if you could do it once and then re-use the conf file it created.  Ideally you should be able to choose to use manual settings or use the autotune file and if the autotune file doesn't exist then you hit a button to go through the process and generate one.  It shouldn't need to do this every single time.  It would also make sense if you could at least raise the fan speed higher than the autotune level.

This variance is killing me.  The people who left the pool have put a pig to us.
