There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

Uptime... (I'm running a single R4 B2) how often should these miners be rebooted?  (or do you even need to?)
Today about 35min ago (after uptime of 6d19h21m24s) I updated to the new stratum+tcp://nya.kano.is:3333 which after saving the new config caused a reboot.
This is the first reboot I've done after two initial reboots when it was brand new a week ago and was setup & running for a solid week on kano.
Is any work 'lost' because of a reboot or does it pick up right where it left off?
Also, I've checked the 'Kernel Log' tab & the 'Monitor' tab - but no luck finding what I'm looking for.
Does the miner keep a log file of the past stats as seen here http://192.168.x.x/cgi-bin/minerStatus.cgi
or, do those stats get erased on every reboot?
Thanks all.

As far as im aware they get erased and a new file created to store current data. Hence why the stats on the status page get reset.

Reboots ( sw or hw wise) always happen if you change frequency or pool configuration. I reboot my R4 once a week but for my S9 i just leave it running till it gets drunk, usually 3~4 weeks per say. For monitoring purpose, I usually hook up my miners to MRR that way you can store hashing information for up to a week in their graphical interface.

Customizable full-featured crypto trading platform in development. Asking for demo if interested.

One of my R4's that stopped hashing on one board has stopped hashing completely after trying to restore the original firmware. The hardware version listed under system overview says "   Socket connect failed: Connection refused".

I have tried powering off several times, reboots, updating firmware, etc. No more hashing. There has to be an easy fix to this without sending to Hong Kong or letting sit in Denver for weeks on end. Any thoughts?

EDIT:  unplugged the original board that did not hash and fired back up, the one remaining board is hashing again at 4th/s!
Exactly same fault here - I think we discovered common issue.


What are you doing about a fix? Sending back to Hong Kong? Denver? Entire unit or only board? Bitmainwarranty is not answering the phone or replying to emails

Not sure why people are still buying these, even with the current price rise 8.7TH only pays $5.7 per day before electricity, add in .05 for power and thats around $3 per day or so , it would take a year to ROI on the $1000 cost of these units.

they should cost half what they do imo but I'll never understand bitcoin miners /shrug  they just keep buying

Just so you know, bitmain's price for btc=$808.21 with REAL price of btc=828.67 (index) or $830 (coinbase).
I cannot support this kind of skulldoggery. what is this, a central committee price?

Will Bitmain never fix their ordering system?  You place the order, you pay your money, and they still never get the payment processed in time and it goes to an expired order status....  Huh  How irritating.

Odd, they have 2 batches, one with 8 TH/s and one with 8.7 TH/s which I assume is running at 550M and 600M, but they didn't update the wattage used for the 8.7 in the specs., so those that don't know will think the faster one is even more efficient than the slower one and uses the same electricity.  In reality, it probably uses about 10% more electricity.

I bought two batch 4 8.7Th/s R4's and I'm replacing 2x S9 with them.
It means less howlin' noise for my home mine.
I will keep two S9's in the soundproof cabinet.

Anyone get their order to update from expired to valid yet?  My order still says expired so I am wondering how long it takes before they update this.

I just wait for the email to come in confirming the order.  I ignore the order status on the website since it seems to be a common issue with the automated BTC payment not updating quite right...

Besides it's only 4:30am in China right now, they'll be in soon enough and start sifting through the orders I'd guess.
