EDIT: - Apparently shipping goes DOWN the more units you order!

Batch 10 of the S3+ has just gone on sale for BTC0.58.

We've been down on luck for the last couple of days, but look at this quirky bit that I stumbled upon (with our luck turning?) when I checked to see how we were doing!

8x difficulty is uncommon - but not unexpected.
10x difficulty is rare.
2x or 3x times difficulty is expected regularly.

It's all basic 101 statistics ...

I do wonder if there have been any university studies of bitcoin hashing statistics.
It's really an amazingly large sample of random probability - I'd guess probably larger than anything ever before it.

You can't look at variance on a block by block basis. It's like flipping a coin and after one go saying "Wow, we've had a big run of heads lately". Generally luck averages out over the long term, but the block solving time can very wildly from one to another. Posting in caps that it doesn't make sense doesn't really make a lot of sense.

It's only been 5hr45min. That's not too long here at slushs. I look at anything over 16hrs long here. Anything under that I can live with. It is nice when we are nailing them down though

MAKES NO DAMN SENSE...

ALL THIS HASHING POWER AND IT TAKES US LONGER TO FIND A BLOCK...

come on, Slush

we need a damn block

two of them within 5 minutes of one another.

The TOTAL HASH POWER OF THE POOL stayed up there over 8 PH/s the whole time.  Well, it did get down to 7.9_____ PH/s for a moment.  However, it stayed about 8 PH/s for the most part.

I think we have more converted Slushers AND older Slushers who have obtained more hashing power!

We are still steady at 8084859 Ghash/s or 8.085 PH/s

I'm leaning more towards buying S4's than buying any more S3's.  My farm is downstairs in the recreation room against the wall adjacent to the garage.  It's nothing to change out the wiring to 10/3 AWG; install 30 AMP NEMA L-14-30-R outlets [circular]; install 30 AMP 2 POLE BREAKERS and plug in a 3 ft. Generator 30 Amp 4-prong to 15-20 Amp (x2) Y-Adapter which will power two S4's.

BY THE WAY:  DOES ANYONE KNOW IF THE INTERNAL PSU GOES BAD IN AN S4, IS IT EASY TO CONNECT AN EXTERNAL PSU TO KEEP IT GOING?

I'm in the process of installing a 125 AMP SUB PANEL [QO SQUARE-D].  That is enough for four (4) 30 AMP outlets to power eight S4's [16 TH/s].

8 S4's x 1380 watts at the wall = 11,040 watts for 16 TH/s TOTAL without over clocking at 2 TH/s EACH connected to four 30 AMP outlets.

OR

30 S3's x 368 watts at the wall [with Corsair AX860 PLATINUM PSU's] = 11,040 watts for 13.65 TH/s [without over clocking] at average of 455 GH/s EACH connected to five 20 AMP outlets.

To me it's a NO BRAINER to invest in S4's for more hashing power with lower costs in power consumption.  I'm keeping my 10 S3's with four more on the way for a total of 14 S3's.  However, those four S3's will be the last S3's I purchase.  I believe it is S4's from here on out till I have 8 of them.

That means [when completed] my house farm will be 6.37 TH/s of S3's [5,152 watts total] at average of 455 GH/s each [without over clocking] and 16 TH/s of S4's [11,040 watts total] at 2 TH/s each.  

TOTAL = 22.37 TH/s Hashing power with 16,192 watts [Divided by 120 watts per amp = 134.93 AMPS] at the wall.  

That leaves me 65.07 AMPS for the rest of the house.  The AC runs at 19 AMPS when it is on.  It starts with 30 AMP surge then settles down to 19 AMPS.  ALL LIGHT BULBS in the house are LED.  So I believe I'm good to go with the 200 AMP MAIN BREAKER PANEL and everything else running in the house, such as AC, stove and oven, fridge, freezer, LED TV (only two - LED TV's - use less power than any other type of TV out there) and LED lights.

Power cost 1 month:           1774.24 USD @ 0.15 per kWH
Revenue per 1 month:         3290.69 USD @ $340.00 for 1.0 BTC / 34,661,425,924 Difficulty
Less power costs 1 month:   1516.46 USD @ $340.00 for 1.0 BTC

We need BTC to go up to $440.00 US and the difficulty to stay around 35,579,431,281:

Power cost 1 month             1774.24 USD @ 0.15 per kWH
Revenue per 1 month           4258.54 USD @ $440.00 for 1.0 BTC / Estimated Next Difficulty: 35,579,431,281 (+2.65%) Source: BitcoinWisdom
Less power cost:                  2484.31 USD @ $440.00 for 1.0 BTC / Estimated Next Difficulty: 35,579,431,281 (+2.65%) Source: BitcoinWisdom

IF BTC went up to $540.00 US and the difficulty went up to around 42,579,431,281 the profitability would be almost the exact same:

Power cost 1 month             1774.24 USD @ 0.15 per kWH
Revenue per 1 month           4254.50 USD @ $440.00 for 1.0 BTC
Less power cost:                  2480.26 USD @ $440.00 for 1.0 BTC


AT PRESENT ON SLUSH WITH 23.7 TH/s HOUSE FARM WOULD BE THE FOLLOWING:

8230601 GH/s (8.230601 PH/s OR 8231 TH/s) is the TOTAL HASHING POWER OF SLUSH ON AVERAGE AT THE MOMENT (estimated)
Block found in 5 hours 7 minutes on average (luck plays a part in it as well).

0.07013480 PER BLOCK FOUND with 23.7 TH/s (estimated) x 5 blocks each day = 0.35067402 each day

THAT WOULD TOTAL 10.5202207 BTC EVERY 30 DAYS

10.5202207 x $340.00 BTC = $3,576.88 US - $1,774.24 for power consumption; with present difficulty
10.5202207 x $440.00 BTC = $4,628.90 US - $1,774.24 for power consumption; with Estimated Next Difficulty: 35,579,431,281 (+2.65%) Source: BitcoinWisdom

So my math compared to the calculator at http://www.bitcoinx.com/profit/ isn't too far off to my first estimate by that calculator.

IF that link does not load the calculator, HIT REFRESH and it should come up.  Also, I believe the "Profitability Decline Per Year" at 0.61 will be much less as difficulty goes up without the price of BTC going up with it.  That profitability calculator was made when the Difficulty was just over 19 Billion.



NOT BAD AT ALL FOR A HOUSE FARM.

i have a dream! that one fay all blocks shall be found by us!

we speak not of these things, instead we strip , we dance, we make rain!!   

It has been a while since our last 24+ hour block, that is when you find out who the true slushes are.

yup

I'm NOT leaving.  Sticking here through thick and thin.

8 hours now.

It's still at 125% for the day.

Damn!!!

6 hours 48 minutes without a block thus far

 


8066815 Ghash/s and NO BLOCK YET!!!

5 hours, 7 minutes (can vary greatly depending on our luck) to find a block with 8.066815 PH/s.  Luck is a little low at the moment...

Either we have more players coming to the game of mining or we have other miners who've seen the light after spending some time at other pools.

We could also have some miners who have been on slush for quite a while who have upgraded their S1's to S3's, purchased S3's on eBay, etc...

Also, several are renting LOTS of TH/s of hashing power in the Cloud and hopping around from pool to pool.

He had a decent amount of hardware.  However, we did NOT see what is still hooked up.  He said he still had S3's hooked up.  I personally believe he simply upgraded his equipment.  Those S1's are 355 watts at the wall just like the S3's.  However, less than half the hashing power of the S3's.

That is a COMMERCIAL building.  In Alabama it is 0.15 per kWH [Residential] and 0.37 per kWH [Commercial].  He could be shutting down because of power costs in relation to BTC price.  It's possible.  Especially, if he is paying COMMERCIAL power prices.

Check out what this guy just took off-line because it is no longer profitable. https://bitcointalksearch.org/topic/about-50ths-offline-youre-welcome-fellow-miners-813649

I'll trade ya my little 40 Gh/s that earns a whopping 0.0001300 per block. I'll be a millionaire in no time!
