PDU's are total waste of money..... Basically they are just very expensive breakers & splicers for rich pussies with no DIY skills.

Just cut the male plug off of each c-13 power cord (use 14 gauge for Miner's PSU rated up to 1600W/220V)
Then direct splice each conductor from all  4x S9's  onto respective conductors of an 8 gauge line
(Make damn sure it's a GOOD solid well protected splice with solder & heavy gauge mars, well taped and in a splice box...)
Connect the 8 gauge to a 30 amp breaker (2 hot, 1 common/neutral, no ground for a 2pole, single phase, 220V)
You can either unplug each miner individually or just switch off the breaker to kill 4 units or kill the whole panel during lightning storms.
Works like a charm... cheap safe and effective and code compliant.

I ran 4x14Th S9's on one breaker at 26 amps for 9 months no problem...till summer heat wave then must watch the breaker does not overheat and trip off...on hot days (+80F)
I've only tripped off once because of overheat...breakers are relatively cheap if one does fail.

If you wish to stay under 80% load (24amps) and avoid the risk of heat/tripping breaker (3x S9/13.5Th + 1xS9/14Th) does the trick.
running them cold (50-65F) makes a HUGE diff in power draw.

Also knowing you only pull max power draw when fans are at 100% ...let's you cheat a bit on the draw.
So in winter with free outdoor -30c cooling... I can/have run 5...YES 5x 13.5Th S9's on a single 30 amp breaker by staggering the startup so each fan is spooled down and hashing along nice & quietly before adding power to the next unit.  (did draw 28amps mind you, but never did trip off)

How can I DOWNGRADE
I just upgraded to 5.2.1 BUT NOW have no temp readings on any of my Dragonmints! B52's & B29's
they also don't report the profit/day correctly anymore

Just FYI...
I run 5.1.3 Enterprise edition...but it still has some glitches reporting  for Siacoin...

Or maybe I really have solved 1109 blocks in 20 minutes!

Yes indeed. this a temp set-up while fixing up better ventilation in the shop.

got tx

The ROI for my batch2 B3 is now projected to be 2 YEARS. Assuming NO further diff increase or price rise.
Of course the diff will go up..but will the price? Highly doubtful the price will keep pace enough to offset the diff increases to make it more profitable.

A.F.T.

Ah my mistake then....my apologies....

So then... They are NOT screwing miners now...I got it now.

@ Genie...never mind
If you have to ask "why?", you wouldn`t understand my answer.

@genie...you misread the word "NOW"

It meant a change in policy ...as in..."They now pay full tx fees, where as, they did not before"

(Granted is was a dangling modifier and poor English grammar but certainly unrelated to my nickname or math skills so let's be civil no?)

Someone please explain to me HOW exactly... "Variance" knows if a pool is large or small?
Variance occurs IRRESPECTIVE OF SIZE. It IS NOT proportional to ANY given hashrate.
Also Variance MAY HURT small pools MORE than a large pool IF/AS THE DIFF INCREASES...
But Large pools CAN and DO suffer EQUALLY in proportion to small pools from Variance AND diff increases.

Too many people confuse the effects of increasing difficulty with Variance.
They can COMPOUND to be devastating OR highly advantagous but ARE NOT related.

A small pool CAN enjoy great luck OR bad over any given time with either NO increase or a dramatic increase in the diff.
The same is true for a large pool.

8 years of pooled mining and input from many maths geniuses has failed to find a "better way" than PPLNS - the stochastic nature of block finding is the actual issue. Even if I charged 10% fee and ran PPS the pool would have gone bankrupt by now. A different cryptocurrency with a deterministic block finding would be so much easier, but so much more game'able.
[/quote]

Respectfully...that argument does not seem to hold true...Via & BTC.com should be evidence enough no?
(Via is currently 1% and pays a portion of the TX while BTC. is 3.5% and shares full TX now)
If it is as you say...How do they survive and why are they the top two dogs in the race?

(And I and Tesla would argue those Math experts are idiots and have no relation to true genius..Meni Rosen schmuck especially)

"Your anger is misguided"
No it is directed at myself alone
I have nothing but respect and admiration appreciation for CK's expertise and efforts. And many of his opinions regarding centralization.
(And to a lesser extent Kano's, even if he is an arrogant asshole)
I also had complete trust and confidence when I recently sent +10K CDN to buy some (NON BTC) machines from CK.


"Presumably the catalyst for your outbreak was the latest fall in bitcoin value"
No it is a complaint against the PPLNS method and the terrible run of luck we had.
Made worse by the influx of a Mega-Whale.
While the risk is sugar coated by the mantra don't worry it will average out in the long term. It is a seductive fallacy
Which explains why we don't complain when we hit early lucky blocks..because we SHOULD have some of those.

"Do you see it as a public service to prevent other people from losing their money by mining here?"
..."you are worsening the situation by making more people try and move away"
No, The mass are idiots and I have no doubt few will read and even less will care or be influenced.
Walter Russell remains obscure overlooked and underappreciated despite his staggeringly important achievements in science which by far eclipse those of his friend Tesla .
Why would I care what others do? It would serve me better that they suffer!

"Do you think I run this pool out of malice to make miners intentionally lose money?"
Certainly NOT and I do wish apologize for inferring so..That was rather childish...I am embarrassed and wish I had not lashed out so.


"but there is absolutely nothing we can do about it"
I disagree, PPLNS is the problem...I can't accept that there are NOT other better methods which can protect the operator AND greatly reduce the risk to miners. Irrespective of pool size.

I SHOULD HAVE made a more polite and elegant argument and appeal to consider changing to a PPS system.
I for one would be happy to pay 4/5% to CK to code and operate a pool to aid in decentralization
I would stay and pay an even higher % if the fee was variable and linked proportionally to pool luck and Hash rate.

So I find his arguments re: providing a service and concern of centralization somewhat hollow.

I will grant that it would be a major pain in the ass and would respect his choice not to take on such a large responsibility.
Certainly I would not expect it to be free.
Nor do I accept that he is not competent enough to do so.

"you've finally had enough of mining at this small pool"
NOT true, it is my proffered choice, I just can't afford the risk.

"why people continue to flock to larger pools - because of the lesser variance the large pools provide"
Not true..."Post hoc ergo promter hoc"... fallacy...
NOT true..Large Pools...DO NOT have LESS variance..Nor will the faster block times affect variance...
THE MAJOR REASON IS THE PAYOUT/REWARD SYSTEM.

Lucky you.... I get only 6/day now..
Face it we all got fucked by Bitmain AGAIN...it's D3 all over again...slightly worse actually
At the current price/diff/daily earnings... my ROI is 4 years.

(of course ROI of same cash in a bank would be NEVER)

What is there to celebrate about?  
I just did a reality check on the true stats we've enjoyed since I started mining here in Oct.
some of us are really getting hurt bad by being here... and have been taking an average of -20% beating for 9+months?
That is just on the block find luck variance.
Add the losses due to an insane diff increase and my ACTUAL rewards here are about 35% of expected..vs a 2-3% PPS pool with NO TX fees.
 
Thank God I hopped off often and caught Slush on some 200% upswings after his bad luck runs or I would have been bust months ago.
I made far FAR  more on BCH and alt's than BTC...Even after dumping most of my BTC during the Dec/17 High.
I was stupid to reinvest in more Sha-256 Asics with 30% failure rates, shit service, expensive RMA shipping and down time.

BTC by PPLNS is a black hole death spiral.

Now we must watch and suffer further as Halong pushes months worth of our shares completely out of the 5nd window.
I read earlier.."One block quickly can change our luck % pretty heavily." BULLSHIT if we hit 5x successive 1% blocks right now it would not come anywhere near close to making up for the losses already suffered.

I'm staring to feel the service which small PPLNS pools do to the Bitcoin community is to take idiots like me out of the game.
It worked.

Hydro Quebec did me an even greater favor refusing an upgrade.
Ciao fellas...

At least I won't be paying any taxes as I have not made a dime in profit. Not even close to ROI...

Actually I'm pretty sure I'm not the first to do this..

Yes it is absolutely NORMAL...
The miner firmware tries to find the best frequency that will give approx the "Ideal" hashrate. (For best performance re: temps and errors etc..)
That's what it is doing when you first fire it up or restart/reboot it.  It first runs/ tests freq's for each board.

The "Real time" is the actual results..which WILL FLUCTUATE.... but usually not dramatically say 5% or so...

YEAH BABY

Oh darn..I was hoping some mysterious benevolent entity was just being generous and mining without a payout address.
But of course the derp's say otherwise

So they are literally off the charts...cool....
Now if they could just find a few blocks and help us out of our bad luck slump.

What's up with the stats page?

for 6 hours we are +160 P but active users reports only about 60 P
Share rate certainly seems to confirm we are indeed over 160P

everyone's derp is taking a beating (well not the top dog/whale of course)
Strange
