[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

[MikeDaSpike]

First off, I have a huge-ass tower with tons of fans and whatnot, I also have five hard disks so the base wattage is higher than the average PC.
I have 2 GTX470 so hopefully this will give some extra insight.


Base wattage: ~280W, 1 watt fluctuation
1 GPU, base clock: ~375W, 2 watts fluctuation, sometimes goes 10W lower for a split second (when it finds a block?)
1 GPU, overclocked: ~389W, same as above
2 GPU, base clock: ~540W, this one is weird, sometimes it goes ~530W and stays there for several seconds, other time it goes ~550W and stays there, but most of the times it's around 540W, 3 watts flunctuation
2 GPU, overclocked: ~585W, sometimes it likes to go all over the place (I've seen values from 510 to 620 watts)

Here are my khash rates:
1 GPU, base clock     ~77000 khash/sec
1 GPU, overclocked   ~93000 khash/sec
2 GPU, base clock   ~156000 khash/sec
2 GPU, overclocked ~185000 khash/sec

I use diablo miner so I disabled the second GPU in device manager, too much trouble removing a GPU for a 5 minute test...
Overclocking was done using EVGA Precision, didn't touch the memory clock (doesn't seem to make a difference to mining) and raised the core clock value from 607MHz to 755 MHz, something of note: playing games with this clock will crash my system.

I read this thread about 2 or 3 times a day, so I might take a while to answer any of the specifics. I also won't be here today for the whole day (I'm about to leave). I hope this helps anyone.

Hey guys, this is thread about pool, not about power consumption, cards, tuning of miners and so on ;-)

[bobR]

This new deal is supposed to be fair
Ya right
before i got a few pennies per round a coin or half coin in a week maybe more
now its imaginary   .001, .0009 , e-8  wait 2 days for .o1
Then wait hrs to get .1 coin in you wallet
Email says it's sent but another hr before it hits your wallet
Thats bs   7 shares for .ooo8 coin
How is that fair   
was better before

COLOR ME GONE

[bobR]

Oh and I thought the IMPOSED FEE
was reduced to 1%
as announced days ago

[bobR]

.00000209 coin pay out
39646 total shares

REALLY

that's BS
39646 shares contributed who is getting all the coins

not the shares even after deducting 2 for you

48/39646 is .0012107 NOT EVEN CLOSE to a full share
how can i have a fraction of a share ?

Somebody is getting a free ride
Who's Idea of fair is this
Send me some of what they were smokin

Hey bobR, I see you're upset, but I don't have an idea what are you talking about?? Are you high?

BobR, the payout is not a share based system any longer, but a score based system. The value of your share degrades the longer it is around, I think I've heard others say it is by 86.5% every 10 minutes. So it is very possible to have a payout that is a fraction of a share because you didn't submit any work for awhile before the round ended.

With that said, it seems that my payout has also dropped below what the difficulty increase should say, but I'm going to wait until I can compare my 7 day averages the period before the score system/difficulty increase and after, because I might just be having a run of bad luck atm.

It sounds like you're CPU mining. I don't think you'll have any better luck mining alone. The odds of you finding a block in less than a year are not very good. Perhaps you exchange some fiat money for Bitcoin, or sell your goods or services instead of mining. You're pretty much guaranteed to be more successful than you would CPU mining.

[slush]

Oh, I think I finally understand.

Yes, you can have a "fraction of a share". Because pool reward calculating isn't share-based. As you have only tiny amount of hashpower in the pool, you have much higher variance every round. And finally, 2% of 50 BTC isnt 2 BTC.

[slush]

it seems that my payout has also dropped below what the difficulty increase should say

That's because yesterday was one of first day with higher difficulty and we also hit very bad day (see the round with almost half of million shares). Today we should be back near the expected reward. That's the life.

[bobR]

Like I said color me gone
somebodys later share  isnt worth crap if didnt contribute first

bad day shit  it's been this way since slush changed his payout
per share was fair even with the possible cheating
THIS IS NOT

giving the last share more is not fair to those that got him there
 

[pla]

it's been this way since slush changed his payout per share was fair even with the possible cheating

Yes, the new scoring somewhat favors faster contributors (who will have a lower ratio of stale shares and a better chance of generating shares closer in time to the pool hitting) - But then, the entire BTC infrastructure favors horsepower over participation, so either take your few pennies a day, or go solo and pray that you ever hit a block within the next few years.  OR, start your own purely-proportional shared pool.  Simple as that.   

Personally, even as a somewhat-penalized low-h/s contributor, I greatly appreciate what Slush has done for us by making it possible to generate any BTC at all without a high-powered GPU to throw at the task.

No, payouts/block went down significantly when the GHash/Sec being contributed nearly doubled, thus making your tiny portion less significant. But, that alone would still average to the same amount of payout per day or week since we'd be solving more blocks.

But, then the difficulty also adjusted upwards by ~40%. THAT is what has reduced your daily/weekly payout.

giving the last share more is not fair to those that got him there

You obviously don't understand how this works. This is like playing the lottery. The actions beforehand have ABSOLUTELY NO BEARING on the outcome of the next play. What you contributed early did absolutely nothing to increase the odds of somebody solving a block shortly there after.

And you also obviously know nothing about statistics and variance. Over time, you will average out to exactly the same total daily/weekly payout due to sometimes submitting shares at the beginning and sometimes submitting shares at the end. Look at the graphs that Slush posted when he made this change. They conclusively show that everything works out nearly exactly the same (except for severely punishing cheaters) over time.

How is FAVORING any contributers fair
the faster they can hash is enough advantage
they get a bigger partial of the coins for more shares
screwing those that only contribute a few shares is hardly fair
especially because they got them early in the go

ok I back off for a while
but i dissagree you are correct it's like the loto
EXCEPT in a pool
what part is done by each individual share contributes equally to finding the correct answer

or from your statement  no one result is any better than any other
Which is what i said later submissions should have no benefit over early submissions


oh dificulty went up
I've not see it...I'm seeing more shares contributed for less pay back

[bitjet]

Hey Slush what are the odds of getting a btc/per hour average going off of our stats?

When logged in the graphs page should have your btc/per day shown, if you run 24/7 you can figure out your btc/per hour easy.

[bitjet]

Slush what is the timeout when your considered to have dropped from the server and reconnected? Becuase I get dropouts for a second (in poclbm) that say unable to connect to server every once in a while, does the server think I am disconnecting/reconnecting? 

[slush]

does the server think I am disconnecting/reconnecting? 

No, that means the request from the miner to server timed out. I was busy during weekend, but I'll set up the third server tomorrow, so this should be definitely fixed, as there is no rising load on the pool (thanks God!).

Umm, actually, in this case - It kinda does.

By playing in a pool, we don't compete against one another.  Slush has kindly broken the problem space up for us so we can cooperate on solving the same target, rather than each going our own way and possibly duplicating effort.  Otherwise, the gripers who point out that "they" solved X blocks but only got such-and-such a share in it would have a valid complaint.

That said - We have a pretty damned big problem space, so the difference between truly random and cooperative amounts to something on the order of one part in 2^128 (256 -80 bits for the fixed-per-block state vector, -32 bits for the share difficulty, -16 bits for the current difficulty).  But still, it gives us just the teensiest edge vs each of us hashing on our own.
