Is anybody using individual 220v surge protectors for the s7/s9s?   If so what are you using?

I am a little worried about trusting a 'whole home' surge protector because it's made more for big electronics (refridgerators/washer/dryer) than computers which may be more sensitive to spikes.
A single S9 pulls about 6 times the wattage of a refrigerator, nearly the same wattage as a washer running 24/7, and over 1/2 of the wattage of a dryer running 24 /7; S9s are "big electronics".
All mine are done with in-box protectors, individuals are cost prohibitive.

So it has emerged that Antpool S9 miners (and others) have ASICBOOST functionality built in. Does anyone know a pool that already supports it, other than antpool?

https://www.reddit.com/r/Bitcoin/comments/63yo27/some_circumstantial_evidence_supporting_the_claim/

Until this is patched we should all be using it to level the paying field somewhat and as a way of maximizing revenue. According to some reddit users, it seems some miners have already started using this.

Essentially to have this working a change in /config/bmminer.conf is required and a pool with the required stratum support is required.

Does anybody have further info?

Of course the easiest would be to point the miners to antpool, but that may not be the best idea  Wink

Newbie in online currency , love learning
Was selling a few s7's on eBay.
Turns out that there is a drop ship company in Newcastle DE that buyers out of the country send to.
At that point the item can be shipped all over the world.
Then the buyer will ask for a return or more items than were actually purchased.
So be careful with buyers with a Newcastle DE shipping address.
eBay knows about this scam and location.

How does this drop ship scam work?

I just sold some items in the US on Amazon to a Canadian buyer who is using drop ship in Portland, Oregon. Should I be concerned about a possible scam?
I think Amazon is different than eBay, more protections.
eBay buyer protection is invalid with dropship.
If there is a problem it is harder to resolve.

if u buy on ebay , u need to trust the person who sell u.
buy high price like miner go amazon better , will feel more secure.

Indeed. It also doesn't seem to do _anything_ per-run - it's just validating the speeds stored in the PIC allow the card to hash sensibly.

It is possible to force it to recalibrate itsself, but apparently that's a support call to BitMain where they add your specific MAC to 'the list' and it gets to run their utility, which presumably does some sort of encrypted communication to the mothership.

Interesting that the non-autotuned boards all show a static clock speed. I have one of these in my autotuning miner and was wondering the cause - it would seem that this might just have been old stock boards.


A hardreset will also trigger the autotune re-calibration as will a change in the controller file system (can't remember the file off the top of my head).

Has anyone experienced this error msg with an S9?  FYI, it is from Kernel Log screen.  Any remedies?  Seem to be a random occurrence at least...

do read temp on Chain[6]
Chain[6] Chip[62] TempTypeID=55 middle offset=27
read failed, old value: Chain[6] Chip[62] local Temp=64
Chain[6] Chip[62] middle Temp=75
Chain[6] Chip[32] TempTypeID=55 middle offset=24
Chain[6] Chip[32] local Temp=50
Chain[6] Chip[32] middle Temp=69
Done read temp on Chain[6]

Thanks!!

I just got my latest batch of s9 in... 2 dead hashbaords in 24 hours, wew that was fast !

What kindof turnanround are you guys are seeing for mailing in the miner for warranty work?

Evil beware: We have waffles!
Either have the host access it or remote in and drop its speed a bit. Bet it is happy again.

I have a b1, 2x b3's, and 2x b5's. Initially the B1 and 3's ran at OEM speed but a while back I had to drop their speed by 50MHz or so because 1 board was starting to drop out from time to time. The b5's are still running full speed with zero problems after all this time...

edit: Oh, if in North America, use Bitmain Warranty in CO. Way better and easier/cheaper to ship to.

Yep, I agree, but it is either have a miner hosted or not mine at all.

Our electricity rates are over US18c a KWH, and summer temps are
over 40c.  I had to stop running S1s and S3s for a few months a year
back when I mined with them at home and my wife thought the noise
was bad then.

I bought the batch 2 before any reliability issues where reported with
the S9 units and had it delivered straight to the host..anyway, it has
nearly paid for itself, as I paid in fiat and just wondering what I am
going to do with it, whether keeping it running all over the place like
it currently does is doing it harm, obviously not worth sending it
back to China with the postage cost/time cost, maybe there is another
host that may be able to repair it and host it.

Thoughts welcomed

cheers

I have asked the host to have a good look at it give it a blow out, which I
assume has been done, it is on the other side of the world from where i am.

Host thinks one blade was gone, until it came back, then says he thinks the
blade is on the way out, just thought this issue might have been encountered
already, its a bit strange
And therein lies the problem with paying for a piece of equipment and surrendering total control of it to someone else.  Undecided

Is the inside clean? Are both fans running? Is the PSU fully working?

I hope someone more knowledgeable than myself may be able to give me an Idea
of what may be the issue with my batch2 S9, it is currently running somewhere
very cold, keeping the eskimo's warm, and I dont have remote access to it I just
moniter it poolside

It ran pretty well flawlessly for around 6 months at 12.8th, it then started having issues of
dropping back to 8.6th for a week or longer then back to 12.8 then to around 11th for
four days then back to 8.6 for a few days them 12.8 then 8.6 where it has been for
a week or so now. Reboot/restart worked the first time, but last time did not seem to
make any difference.

Does this seem like a blade issue or control board issue, or might there be another
cause for this behaviour

Appreciate any help

A version of Core 0.14 that took 2 weeks to edit out the segwit garbage.

Oh my ! LOL !
Yeah, I know it's funny; it should have taken me way less than 2 weeks to recode a wallet that took a team of devs 2 months to code, right?

Why not run a bitcoin unlimited node?
Yes, because the answer to stopping the centralization of Bitcoin around the Core dev's beliefs is to centralize Bitcoin around the BU dev's beliefs....  Undecided

Thank you guys for shareing your experience. For me the problems started with the autotune models and I can only speak out of personal experience. From my point of view, if the autotune software burns chips, it doesn't do its job good.

Agreed.  There should be an underclock option.


Well, apparently we seem to get this option by doing the HagssFIN hack - if we dare  Grin  Did somebody?



There use to be such high demand for manual control ability with autotune S9 models, but now, has someone tried my method with S9?
I've done this successfully to my two R4s.

This is also S9 related, so I thought to share this here as well.
If there is someone with a desire for non-autotune settings, be brave and please report if you get same results as I had  Wink

Well, this is an interesting find and I thought I'll share it with you. Smiley

I had a problem booting my Antminer R4 8.0 Th/s, batch 2, autotune-model.

So I went looking in here:
Bitmain.com: Three Ways to Restore Factory Settings (R4/S9/T9)
https://enforum.bitmain.com/bbs/topics/3957

I used the last option in the list, IP Reporter button restore.
Quote from: Bitmain
Usage: Please power off the miner, then hold down the IP Reporter and don’t release it. At the same time, please power on the miner.
Releasing the IP Reporter after 5 seconds, the machine will automatically restore factory settings.

My miner restored with firmware Aug. 9 2016 and autotune settings were gone.
I am now suddenly able to control frequency and custom fan settings.  Cheesy

This was not my original problem, but I'm happy with it.
My original problem was that the miner jammed somehow in the booting process and didn't even show up in my router ip list.

You are free to run whatever client you wish or support a different chain. Nobody is forcing you to use Core. However, the best and most competent developers contribute  and maintain code to the core client. You are free to open a Git and submit proposals if know of a beneficial feature that is not currently available.

If you do not support segwit, run versions prior to 0.13.1, that is if you run a node.
...
Yes, it is wholly true that if you want to run a Core node, you are free to not support segwit by running an older, less optimized version of Core that is worse for the network as a whole.
Meanwhile in the decentralized world where Bitcoin is supposed to be run by a consensus, if the majority want x in a wallet, then Core devs should put x in the wallet. In the decentralized world where Bitcoin is supposed to be run by a consensus, one shouldn't have to make the choice between a client that is, literally, slower and one that signals something that the majority obviously don't want.

"You are free to open a Git and submit proposals if know of a beneficial feature that is not currently available." Satoshi Nakamoto, himself, could write a BIP that 99% of the community wants and if the devs personally dislike the change, then it's not going into Core.
