Ladies and Gentlemen, please fasten your seatbelts.

And place your tray tables in the upright position.

As we begin our final burn... To. Da. Moon.

cuz we:



Buy, Hold. Never Sell.

Oh man!

You could've used (or sold!) those 15 x $400 = $6,000 in S4 coupon discounts!

damns, yo!

-dave

I bought eight S5+'s and they gave me nine S7 coupons (but I've also bought six S5's throughout the year -- not sure if that factored in to their calculations)

-dave

Actually, I received a replacement hash board for my S5 recently which has the many-small heat sinks, one attached to each asic chip, and it works great, and runs a LOT cooler than the old-style cooling system, where all the chips on the board have thermal paste on top of them, and they are all in contact with one large heat sink.

So I'm sure the S7 (and S5+) need far less fan power to keep them cool, which is why they can be packaged so much more densely.

-dave

I'm have nine S7 Coupons for sale (on eBay) for only $35 each:

  $100-OFF Coupons for Bitmain Antminer S7's

Get em before they expire on Oct 12th!

Thanks,

Thanks for the update!  And thanks for extending the 15-day warranty on these "second-hand" S5's to 30 days!  It makes them a little easier to sell :-)

By the way, just a little English-language suggestion: PLEASE stop calling these "second hand" -- that term has very negative connotations in English that you would NOT want associated with your products: the term is usually used to describe worn, damaged and degraded items (usually clothing or furniture) that have been passed down person to person (or generations of a family).  Second hand goods are typically given way for free to the poor or sold for a fraction of their original price. 

The professional terms used in the electronics industry for used devices that are tested, maybe-repaired and resold by the original manufacturer are:

  - "Factory Refurbished"
  - "Factory Certified Returns"
  - "Open Box Items"

and it's also standard in the industry to offer the same full warranty on such items as new good, to assure buyers they are just as good as new!

Come over to PA! My kwh's are 8 cents!  Fracking is bad for the environment but good for gas fired power plant electricity rates, apparently...

I might have to dust off my lucky 8GH BFL Jalelpeno and point it here!

Oh and by the way, while I'm at it, same for those who attack dogie every time he opens his mouth.  Get a life, already.  If you don't have anything constructive to add to the discussion, your ad hominem insults are just hateful noise to everyone else who is here to learn and participate in bitcoin technology, not to watch people fling shit at one another.  If you don't like what he (or anyone else here) has to say, there is an "ignore" link to your left.  Please use it.

Sometimes I wish that the moderators would enforce the one simple rule of civilized behavior that we all should have learned as children: if you can't say anything nice, don't say anything at all.  But alas, they are moderators, not baby sitters :-)

-dave

He said it's autumn there, so I assume that means he's quoting the price of electricity in AUD not USD.  The exchange rate is like .7 AUD = 1 USD so his 50 cents is roughly equal to 35 of ours (us being we USA-ites).

And that seems about right.  According to this chart:

  Electricity prices around the world in $/kWh
  http://shrinkthatfootprint.com/average-electricity-prices-kwh#more-3858

The average Aussie pays .29 usd /kWh while the US average is .12 cents -- I pay .08 $/kWh because Pennsylvania is frackland and the natural gas glut is currently keeping our electricity unusually cheap.

In fact, I wanna buy an abandoned factory with utility grade power and start a mining farm.

Then I could stop commuting 90 miles to NYC every day for a living... anyone want to bank roll that?  I got just the place all picked out... :-)

My rental was simpler: 100TH (from WestHash.com) pointed at CKPool in the wee hours of Wednesday morning, the 29th, at like 1 or 2am.

Cost me 1 BTC to run that for about 21 or 22 hours, basically all day Wednesday.  

I've gotten .162 BTC on every block since then, so far 8 of them.  Which brings my total payouts from CKpool to about 1.35 btc  ...and counting!

But don't hate me yet.  My last bet before that, also 100th for 21hrs for 1 BTC, paid just a fraction on two blocks that were solved just as my hash power came online, after which this pool saw a run of bad pool luck like I have never seen, and didnt crack a block for like a week.

I do love the 500% pplns because long after I'd thought it was over, I did still get paid a little more, on the two blocks that hit after that long run of nothing.  But, all told, that 1BTC bet barely paid me back .5 btc

So yeah -- pool luck can be a cruel mistress!

No dashes before -- all o's on both blades.  And it was hashing fine out of the box at stock freq for a few hours, then I cranked it up to 400 and it was doing about 1.3 TH nicely.  But so frickin loud.  That's when I decided not to leave well enough alone, and to replace the fan with an S3 push. 

Today its hashing on the one blade at 350 freq again.  And I can see the S3 fan is not going to be enough.  Its barely keeping the one blade at stock clock under 60 degrees...

I did reseat all the power and data cables I can see and reach from the top.  I guess a full tear-down is in order.  What was the good thermal paste again?

-dave

Mine looks like that too -- it was working for a day or two.  It was too loud in my office for me to even speak on the phone, so last night I removed the pull-fan fro one of my S3's and replaced the S5's push fan with it -- had to splice to extend the wires because they didn't reach.

Now it is nice & quiet, and still running at acceptable temps < 65

BUT chain #2 is dead -- all dashes :-(

How do I go about troubleshooting?  I reseated all of the power connectors (twice), and the two grey data connectors on top.  But I'm not sure what to try next.  My warranty is clearly null and void :-)

thanks,

-dave

Of course!  The word "chance" has gambling connotations, while the word "luck" is loaded with superstitious undertones :-)  The only difference comes from the perspective of the person you ask.

The generic term, the mathematical term, is probability.  I guess the guy who thinks payout from different pools on different days are controlled by "chance" had a dad who played the ponies.  While the guy who calls it "luck" had a mom who believed her horoscope, threw salt over her shoulder and knocked on wood for "good luck".

My mom was an engineer -- I call it probability. 

thanks,

-dave

who *did* have step dad who played the ponies, and a grandmother who pitched salt -- so don't go getting all offended, now

Is it still stable?

Westhash and Nicehash orders keep getting canceled after a half hour or so when I point them at Slush's pool.  I've been forced to only use CKPool for my rentals :-(

I had the pool "verificator" tell me the diff was too low.  After several tests it may say it is ok, but usually it reports that slush's pool is "incompatible" and occasionally that it is having connection problems.

If anyone wants to investigate, this Pool verificator can be found on the new order page only, an is only available to logged in users, but registration is free and you dont need to fund the account to get to the that page.

I'd love to know why Westhash + Nicehash can't mine at Slush's pool for me!

Ahh darn it.  I spoke too soon.  The nicehash order was auto-canceled too, after about a half an hour, saying "Action" Cancelled - placeholder order" with a link to their FAQ:

  Why was my order canceled (placeholders)?
  https://www.nicehash.com/?p=faq#faqb13

Ah well, back to CKPool I guess

thanks,

-dave

Ah, that was the problem -- Westhash is for pools on this (U.S.) side of the pond :-) I switched to nicehash.com and slush seems to be working much better!

No bot, yet.  I'm still in training ... :-)

Thanks!

-dave

I unleashed another 100TH at the pool for about the next 20 hours or so.

Last time I tried this ya didn't hit a block for the next 4 days!

Hoping I will not bring such dark magic to the realm this week :-)

I am groot!  I mean gigawatt :-)

thanks,

-dave

Oh, and I swear to Gaea I will -- Never. Ever. understand PPLNS, or any other pool payout scheme for that matter.  That 100TH rental I ran last week pretty much fell flat on its face.  About $250 basically down the drain, right?  So I'd completely written it off of course, and chalked it up to Just Real Bad Luck.

And then today I see that I got 3 payouts, about $125 totally unexpected from CKpool.  

Huh?

That's why ya gotta use a pool where you trust the operators, eh? :-)

I rented some hash power at WestHash tonight (just a little bit: 100TH :-) and pointed the order at Slush's pool tonight and it got auto-canceled after about 15 minutes.

The "Pool verificator" said Slush's pool was compatible, but right after the order started the order status page kept saying something like "pool connection problems, pool diff too low, minimum difficulty is 127" which is a problem, since i have the worker configured for 1024 difficulty pool-side.

Then it started hashing and managed to get up to about 30TH before the order suddenly got auto-canceled.  it refunded the charges, which is good at least.  I was able to do this last week on CKPool (kano.is)...

Is slush's pool known to work with westhash rented rigs?  Is it incompatible?

From this it looks like it should be supported:

Which mining pools are supported?

thanks in advance for any insight, tips or tricks!

-dave

Yeah it does seem like my next experiment should be less hashrate for a longer-term, eh?  It looked to me like you could only place 24-hour long orders.  Am I missing where you can rent for longer?  Or do you just have to go in every day and "re-up" before the order ends, to keep it runnng for, say, a week?
