Anyone have any info on how many GHS-THS it takes to find and solve a block?
I am thinking of starting a private pool and only allowing x amount of members totalling x amount of hashing

Then when we find a block it will be distributed equally amongst the members naturally all members will be required to bring their share of that x amount of hashing to the table.

I myself have 10TH/s to bring to the table

second question anyone know how many watts a overclocked s3+ uses? I am thinking of upgrading my units to s3 units but need to weigh in if there is any true savings to go that route currently I run a rack of cointerras

and why only 1 payout yesterday i normally fetch 4-5

I have 10 Bitmain Antminer S3+ overclocked at 231.5 MHz to 237 MHz.  Combined, according to Slush's Pool, I'm averaging 4.7 TH's with those 10 S3+s, even though I KNOW they are hashing faster than that. 

It is hard to say how many watts at the wall you will pull per S3 without knowing the PSU used.  I'm using five (5) Corsair AX860's [One AX860 for every two S3's].  My AX860's are PLATINUM rated and are very power efficient.  I'm pulling 718 watts at the wall with an AX860 powering two Antminer S3's without being over clocked; 728 watts at the wall with just a slight bit of over clocking.  I've seen other PSU's on youtube that would pull as much as 740 to 760 at the wall without over clocking.

A cheap easy way to KNOW your power usage is to order the following on Amazon:

http://www.amazon.com/gp/product/B000RGF29Q/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

The P3 International P4460 Kill A Watt EZ Electricity Usage Monitor will allow you to edit how much your power company charges per kWH.  Then, you can see how much power was used by what is plugged into it.  This is a valuable tool if you have a business that you have used to buy your miners and you need to KNOW how much power the miners are using so you can write off the power usage on your taxes.  Do NOT write it off on your taxes if you are not reporting your bit coin mining earnings.

The pool idea sounds great!  CK has a solo mining pool but the miner who found the block gets all the earnings minus .5%

At present difficulty [34,661,425,924], finding a block is represented depending on hashing power.  I did a few "What If's" based on assumed hashing power:


50 TH/s = 34 days, 11 hours (can vary greatly depending on your luck)

60 TH/s = 28 days, 17 hours (can vary greatly depending on your luck)

70 TH/s = 24 days, 14 hours (can vary greatly depending on your luck)

80 TH/s = 21 days, 12 hours (can vary greatly depending on your luck)

90 TH/s = 19 days, 3 hours (can vary greatly depending on your luck)

100 TH/s = 17 days, 5 hours (can vary greatly depending on your luck)

110 TH/s = 15 days, 15 hours (can vary greatly depending on your luck)

120 TH/s = 14 days, 8 hours (can vary greatly depending on your luck)

130 TH/s = 13 days, 6 hours (can vary greatly depending on your luck)

140 TH/s = 12 days, 7 hours (can vary greatly depending on your luck)

150 TH/s = 11 days, 11 hours (can vary greatly depending on your luck)

160 TH/s = 10 days, 18 hours (can vary greatly depending on your luck)

170 TH/s = 10 days, 3 hours (can vary greatly depending on your luck)

180 TH/s = 9 days, 13 hours (can vary greatly depending on your luck)

190 TH/s = 9 days, 1 hour (can vary greatly depending on your luck)

200 TH/s = 8 days, 14 hours (can vary greatly depending on your luck)



THIS INFO ABOVE should be enough to get you started with an idea of what you need to find something in a matter of two weeks without much problem.  IF you want to solve a block EACH DAY, you need the following at present difficulty:

1700 TH/s (1.7 PH/s) = 1 day (can vary greatly depending on your luck)

SLUSH'S POOL [LATELY] has averaged 6800 TH/s (6.8 PH/s) 6 hours, 4 minutes (can vary greatly depending on your luck).  THAT IS FOUR (4) BLOCKS EACH DAY ON AVERAGE.  However, we have been doing about 5.2 blocks each day on average the last 30 Days.

Four (4) Blocks each day x .01523747 average shares = .06094988 BTC per day x 30 days = 1.82849640 BTC
However, we have done 5.2 blocks per day for the last 30 days x .01523747 average shares = .07923484 x 30 days = 2.37704532
All of that with 4.6 TH/s Farm.  I've made 0.88 BTC the last 7.5 days with this small farm.  We've had a good last 7.5 days.

I have 10 more S3's on the way from Batch 10 as soon as they are available!

Hope this helps...

A BLOCK [$340.00 x 25 = $8,500.00]

60 TH/s = 28 days, 17 hours (can vary greatly depending on your luck)  ABOUT A MONTH

     12 Miner Farms at 5 TH/s minimum per Farm $708.33 per block found
     6 Miner Farms at 10 TH/s minimum per Farm $1,416.66 per block found
     OR
     4 miners at 5 TH/s minimum per Farm $708.33 per block found
     4 miners at 10 TH/s minimum per Farm $1,416.66 per block found


120 TH/s = 14 days, 8 hours (can vary greatly depending on your luck) ABOUT 15 DAYS

     8 miners at 5 TH/s minimum per Farm $354.17 per block x 2 blocks in 1 month = $708.33 per 5 TH/s Farm in 30-Days
     8 miners at 10 TH/s minimum per Farm $708.33 per block x 2 blocks in 1 month = $1,416.66 per 10 TH/s Farm in 30-Days
    

180 TH/s = 9 days, 13 hours (can vary greatly depending on your luck) ABOUT 10-DAYS

     12 miners at 5 TH/s minimum per Farm $235.87 per block x 3 blocks in 1 month = $708.33 per 5 TH/s Farm in 30-Days
     12 miners at 10 TH/s minimum per Farm $471.75 per block x 3 blocks in 1 month = $1,416.66 per 10 TH/s Farm in 30-Day

Did a little more math for you.

The hard part will be to get the mining farms to join you.

Also, I can make approximately 2.7 BTC ($918.00 GROSS @ $340 per BTC) on average in Slush's pool every month with 4.6 TH's (10 Bitmain AntMiner S3's).  I have 10 more S3's on the way as soon as Batch 10 comes available.

I personally believe BTC is heading for $550 to $600 by X-MAS.  I'm keeping EVERY SINGLE BTC I MAKE IN MY WALLET TILL IT REACHS $550 MINIMUM.

I figure your pool would work better with larger farms of 20 TH/s [minimum] EACH with a TOTAL HASHING POWER OF 340 TH/s [5 days, 1 hour (can vary greatly depending on your luck)].  That would be approximately 6 blocks every 30 Days for a total of $51,000 @ $340.00 per BTC.  Divide 340 by 20 TH/s = 17.  Divide $51,000 by Seventeen (17) 20 TH/s mining Farms = $3,000.00 every 30 Days.

IF you compare 20 TH/s of hashing power used on Slush's Pool, one could make approximately 12 BTC every 30 Days = $4,080.00

BOTTOM LINE:  A LARGE pool is hard to beat if you have a lot of hashing power.  IF you have an ASTRONOMICAL SIZED FARM IN A WAREHOUSE, such as 240 TH/s all by yourself [7 days, 4 hours (can vary greatly depending on your luck)]; IT WOULD BE BETTER TO MINE SOLO THAN JOIN ANY POOL!  However, Slush's Pool is the best thing going out of any pool right now.  As long as we stay the size we are.  It would still be better if it gets larger; though I hope it doesn't get over 9 PH/s average.  Right now we average about 6.8 PH/s.

The ONLY way your pool would be better is if the pool got very lucky quite often.  That would be a risk the pool members would take.

MY HONEST OPINION

sweeeeeeeeeet

can't wait for Batch 10 of the S3's to come available.  I'm getting 10 more of them for approximately 9.4 to 9.6 TH/s total.

The 10 I have now are clocked at 231.4 MHz each and Slush says they are at 4793.739 Ghash/s (4.793739 TH/s) respectively at the moment.

[dmwardjr]

The first block we hit yesterday (10/06/14) was at 03:41:11 hours Slush's time and it took 5 hours 40 minutes to hit it.  It has been almost 5 hours now since our last block.  That means we MIGHT hit a block here shortly.  It is 03:18 hours Slush's time at the moment.

Pool luck (1 day, 7 days, 30 days):   222%, 165%, 127%

Approx. cluster performance (30 min average):   7979089 Ghash/s (7.979089 PH/s)  
5 hours, 10 minutes to find a block at this hashing power (can vary greatly depending on your luck)
We are definitely due one...

Bitcoin Difficulty:   34,661,425,924
Estimated Next Difficulty:   35,984,905,151 (+3.82%) 
5 hours, 22 minutes at the new estimated difficulty at present hashing power of 7.979089 PH/s  (can vary greatly depending on your luck)

Here's an explanation for the price dip we just went thru...

[dmwardjr]

Here's an explanation for the price dip we just went thru...

http://[Suspicious link removed]/1repIe5

Some whales (BIG FISH) were purposely selling all of a sudden to create a panic sell to get the price down so they can buy back at a lower price to accumulate more coin.  It is destined for $550 to $600 range between December and February.  We had a BIG WALL of 19,000 at one point on STAMP last night at midnight [BIG FISH asking $300.00 for 1 BTC].

I watch the exchanges quite a bit late at night.  The BIG swings normally occur between 12 midnight and 6:00am Central (Chicago) Time.  That is when a lot of the BIG whales from China are in the game to sell off huge amounts all of a sudden to create a panic for those who do not know any better; only to buy back when the price is lower to accumulate more coin.

I saw several who would sell 1000 BTC and buy it right back 15 seconds later on STAMP.  I WATCHED the order book last night on STAMP.  Again, they did this to make people THINK it was a PANIC sell off to manipulate the price down for those who do not know any better; and THEN buy it back at a lower price to accumulate more coin.  However, THE BIG BEARS NO BETTER.  Many BIG BEARS sold when the BIG WHALES did at about $325.00; THEN the BIG BEARS BOUGHT BACK IN at $300.00 to accumulate more coin.

Serioiusly...   We have a LOT of BIG players who KNOW BTC is here to stay are going to pump it up here slowly over the next couple of months.  Most of the big sell offs occur on the weekend.  I believe part of them selling off are BIG mining farms in China and elsewhere.  Happens almost every weekend here lately.

That is THE WALL I was talking about!  It got as high as about 20,000 in that picture you provide in the link on STAMP.

I wish I had about $300,000 US.  I would have bought into that WALL last night for $300.00.  At $335.69 now; I would be up $33,500 right now.  However, I would sit on it.  IT IS DESTINED TO GO UP MUCH MUCH HIGHER.

THAT is why I'm sitting on the BTC I mine till it goes up.

[dmwardjr]

What did I tell you:

I KNEW we were due a block [2014-10-07 03:28:10]

03:41:11 this time yesterday after a 5 hour dry spell.

[dmwardjr]

Well, dude who asked, "What is the explanation for BTC going down" deleted his question.

LOL

FOUND IT:

Has anybody seen what's been happening to the BTC price lately?  Yikes!!
Does anyone have any theories as to why this is happening?

[dmwardjr]

The more I think about it... The new Bitmain Antminer S4 is a good choice for the price.  Especially, since it includes a built in PSU [Gold Rated].  My ONLY concern is IF the built in PSU goes down, can it be EASILY hooked up to an external 1600 Watt PSU?

Is there anyone on this forum who has an S4 [Who may have opened it up] that could tell me if it can easily be hooked up to an external PSU in the event the internal PSU goes down?

It would take 4 Antminer S3's to make 1 S4.  THEN you have to buy 2 PSU's to power the 4 S3's.  Yet, you are still short approximately 200 GH/s from the 2 TH/s hashing power of the S4.

ALSO, 4 Antminer S3's with two Corsair AX860's [PLATINUM] would be a combined total of 1440 watts at the wall.  You get 200 GH/s more hashing power with the S4 and 1380 Watts at the wall.  60 Watts LESS POWER WHILE GAINING 200 GH's more hashing power.  THAT IS EXTREMELY ATTRACTIVE!

I'm tempted to buy 2 S4's instead of 10 S3's.  VERY TEMPTED!!!!

Yes, the S4 requires 30 AMP outlets with a 20 AMP splitter cord to make it possible to hook up 2 S4's on a 30 AMP circuit.  I've already addressed this earlier on page 940 of THIS forum.

10.5 min avg blocks since new diff so might not go up much next round except even at that ridiculous price batch 1 s4 sold out in 12 hours

Batch 1 wasn't that large to begin with, this is from their post in S4 thread:
S4'B1 is limited in quantity, as it is the first mass production after the development stage.

understood still dont see how anyone would buy that 3.4 btc for .01 w gh/s improvement over s3+ .069 vs .070 when 2 s3+ is 1.16 and prob cheaper you can get 4 for over 1 btc cheaper and have same hash rate and I know it has an integrated psu so they wont have to buy 2 140 dollar psu's but they have to find a 16 amp power cord that fits hmmmmm... gonna be tuff 15 amp is what 12 gauge and thats already thicker then standard computer power cord bet it costs a bit and as standard outlets in the us are 15 amp rated I'm sure warranties will be void

Agree, I wonder if they noticed that server psu and those 4 large fans? It is going to be very loud.
S4 was obviously geared for their hosting option or a data center not the home. Either way you will never see ROI with it but sheep will be sheep.

yup i was looking online and it appears only 250 volt solutions for above 15 amp power cords

Wouldn't surprise me if the S5 when it comes out is a 220v only, just hope they don't drop the S3 line.

Don't let this come across as "attacking" anyone:

You fail to realize the S4 COMES WITH A POWER SUPPLY BUILT IN.  YOU DO NOT HAVE TO BUY A PSU TO POWER THE THING.  We have to buy PSU's to power the 3 or 4 Antminer S3's to get about the same hashing power.  I prefer the S3+ at this point in time.  However, the S4 will probably have a greater resale value down the road if you choose to get out of mining at some point in time.

So, you save money not having to buy PSU.  Their PSU is GOLD rated and not PLATINUM rated like my Corsair AX860's powering my S3's.

Also, someone made a good point about the "watts consumed at the wall."  Approximately 1400 watts OR 1380 watts to be exact when you multiply the .69 watts x 2,000 GH/s.

TRY putting two of these on a 20 AMP circuit; EVEN WHEN YOU REPLACE THE STANDARD 15 AMP RECEPTACLE (OUTLET) WITH A 20 AMP OUTLET.  You would only be able to put ONE of these bad boys on that ONE 20 AMP OUTLET.  20 AMPS will drive 2400 WATTS.

Do the math:  1400 watts x 2 Bitmain Antminer S4's is 2800 WATTS.  The 12/2 wire will get too hot.  IF you have 14/2, YOUR HOUSE WILL BURN DOWN if the breaker doesn't trip!

SOLUTION:

RUN 10/3 wire [Rated at 30 AMPS] to a 30 AMP OUTLET [NEMA L-14-30-R (circular/4 prong)].  IT MUST BE NEMA L-14-30-R/CIRCULAR.  OTHERWISE, IT WILL NOT ALLOW THE NEXT THING I MENTION TO PLUG INTO IT.


http://www.homedepot.com/p/Pass-Seymour-30-Amp-Self-Grounding-Locking-Single-Outlet-Receptacle-Black-L1430RCCV3/100155901?N=5yc1vZc33aZ1z11vjb#specifications



THEN GET THE FOLLOWING EXTENSION CORD [3 ft. Generator 30 Amp 4-prong to 15-20 Amp (x2) Y-Adapter] TO PLUG INTO THE NEMA L-14-30-R OUTLET:

This extension cord splits INTO TWO 20 AMP PLUGS to plug in two Bitmain Antminer S4's.  It's only 3 feet but it gets the job done.

http://www.homedepot.com/p/Rodale-3-ft-Generator-30-Amp-4-prong-to-15-20-Amp-x2-Y-Adapter-G30AM420AY/202669114?N=5yc1vZc4neZ1z11vjb




DON'T FORGET THE DOUBLE POLE 30 AMP BREAKER.

http://www.homedepot.com/s/double%2520pole%252030%2520amp%2520breaker?NCNI-5


Problem solved; IF YOU HAVE THE S4's in mind.  Now you have 30 AMP circuit [3600 watts] for the 2800 watts required for two S4's

David

Exactly and now you have spent more money then buying your 2 1000w gold psu's for powering your s3+ and still spent 1 btc more fore same hash rate to get a .001 better efficency anyone who buys s4 is doing it wrong unless you already have the infrastructure it is not home miner friendly at all and with 5% diff jumps will mine 2.45 btc before un profitable so upside down it will always be i was really hoping for a 2 btc price point and a home friendly setup but they are pushing there hosting thru hashnest supa hard atm
