Possible bug on the bitcoin blockchain? Weird - please explain

I just don't get it, maybe I don't understand the blockchain correctly, how can block 839972 and block 839973 have a time earlier than block 839971?  Thanks, if someone could explain, best, Louis




Code:
bitcoin@bitcoin:~$ for block in {839968..839975}; do echo $block: $(bitcoin-cli getblock $(bitcoin-cli getblockhash $block) 2 | ./jq ".time"); done
839968: 1713555843
839969: 1713556158
839970: 1713556364
839971: 1713558153
839972: 1713558054
839973: 1713558091
839974: 1713558976
839975: 1713559220

Good news - who thinks this action justified a $15.00 price hike (2015-02-03 ~ 08:00 EST)  or does it have nothing to do with it?

You're a few days late.

Oops - sorry about that, thought it was a new topic.  Any idea when this could be implemented?

Re: S7 - please help me understand...

Hi,

You are right it was 3 650 Watt PS's for only one S7, but you are wrong on the fact that the machine would not work.  It's works fine and would give me an avergae of 3.848 TH based on a sample of a bit more than 5 days, however for this to happen I had to lower the freq to 579.17 the HW error rate was 0.01% and it was pulling ~ 850 Watts at the wall on 240V AC.   I bought the PS from bitmain and I am now getting 4.654 TH based on a 12 day sample (each 15 minutes)  with a 0.0002% HW error rate, the three boards are respectively at 46, 47, and 49 degrees Celsius and the two fans at 3720 RPM each.   The one only real amazing bizarre thing I have noticed is that when I take a voltage reading with my voltmeter it sometimes "bug's" the machine were it consumes much more power and basically gives no TH's, very weird, simple reboot solves the case.   My theory (with help of my cousin who is electronician) is that the test leads of the (cheap) voltmeter act as an antenna and transmits noise/interference to the controller board causing a dysfunction.

Thanks for the info, always good to have things in perspective.  I guess the total number of all bank accounts in the world is so so so much smaller...  This is for sure a good expression of at least one side of bitcoin that is very strong.

Ok - seems up and running now.  Interesting they seem to be taking an option on a combined BTC price/difficulty/miner equipment cost, they are offering to sell you the same machine but deliver in about 40 days for about 20% (~ $250.00 USD) less.  What do you think?  These days such a machine should generate an average profit of about (it's a best guess) 6.75 USD/day for the next 40 or so days.

Hopefully you've got at least a 208V plug for the Bitmain PSU - it won't even fire up on standard US 110/120V plugs.  I don't know where you're located, but thought I'd point that out for you.  A single EVGA 1300G2 will drive that S7 - but you need to get a couple cable splitters so you can have enough PCI connections.

Hi,

Thanks for the info, I'm all ready on 240V circuit so it should be fine.   I'm located in Montreal, Qubec, Canada.  I have ordered 4 units, most likely will use two (plan on buying an another S7 soon for a freind and maybe an extra one for me).

Hi,

Sorry guys, did not want to be negative, you are right I am just not patient enough.  Thanks to all, and my apologies if I insulted anyone, will try to be more careful in my wording.  Regards, Louis

I can confirm that beeps are not only for fan/temp issues, have a look at my stats you can see that there is no issue with that, but I can simulate a beep by simply shutting down my router.   I think a beep alarm means something is wrong.   I can possibly help you with this issue if you want to iron-it out.  PM me if you want with a phone number.  Good day, Louis

p.s. would be curious to compare your stats with mine, mostly the HW % values (my two columns follwing _HW)

No, I have no control over what the Thermaltake power supply outputs, I was just deceived that it did not give 12V.  I will be trying it with bitmain's power supply, I expect to get the promised performance with that.

This board does not seem too strong,  asked a fairly pertinent question in the mining board hours ago and nothing yet.

Hey,

Many thanks to all and mostly to user "Quickseller" who got the answer I was looking for.   This finally does all make sense,  I was expecting a payment from them only in the morning, they just paid out sooner I guess.  Also, if anyone would like to give a go at my question in mining that would really help me.  A nice Sunday to all, Louis

S7 - please help me understand...

Hi,

Received my S7 batch 4 (4.66 TH/s), I decided to match it with 3xThermaltake SP−650PCBUS @ 80.00 CAD each, I'm in computers and the plan is to reuse these eventually in systems I build or for repair.  Now, had quite a deception when I started the miner, was doing only about 1 TH/s.  Checked the voltages and had about 11.5 or so.  

So I decided to play with the frequency only going slower not higher, I thought I found the sweet spot at 520.83 where I was getting about 3.05 TH/s with voltages of 11.22 11.23 and 11.29.   I setup some  logging in a database to follow this, after a couple of days I noticed my average was slowly going down, is my miner going to die?   I'm a bit scared but decided to lower even more and now it's doing even better at 508.33 with the same voltages, can I hurt my little buddy with this?  

Thanks, Louis

Hi,

Sorry I guess I did not quite express my self well enought,  rain falls from the sky, I would not ask from where does the rain fall.  But I could ask why it seemed a bit tinted, or unusual or something like that.  So if someone can get me more info of the source (for exemple if you ar in the recipients, maybe you know who sent the money).  I hope my question is clear, good evening to all.
