38241  Bitcoin / Mining support / Re: Spondoolies Tech SP35- Timer setup ssh- Voltage Problem on: April 08, 2015, 10:29:36 PM
Hello everyone
Hard Facts:
Sp35, FW 2.6.14

Since the new FW it is possible to set up Timer settings.

1st Problem) The maximum Voltage is 0,790v to achieve max. TH ("Set your Maximum voltage limit to 0.790 for unlimited or less for under-voltage")
the maximum you can enter in timer settings via GUI is 0,70v. ("0.58 - 0.7 (0 to stop mining)").
Solution: I talked to spondoolies tech support and itīs quite easy to change the 0,70v to 0,79v in crontab via ssh.

BUT

2nd Problem)
Setting timer does not only change max voltage it also changes start voltage and automatically sets it to 0,05v below setted max voltage

So if you set 0,79v in crontab via ssh the starting voltage is automatically 0,05v below --> 0,74v and this is too high! it couses miner not to start!

-> Tech Support can not help

now the QUESTION  who can help me with this problem?

Thanx a lot!

try 0.78 v  which gives you   0.73 for starting volts  if it won't start

try 0.77v which gives you    0.72 for starting volts  if it won't start

try 0.76v which gives you   0.71 for start volts  if it won't start

try 0.75v which gives you  0.70 for start volts if it won't start

try 0.74v which gives you 0.69 for start volts      

Don't argue jsut follow the above instructions.

Most likely it will do one of the last two ones.

Once you discover and determine which one does work. post back.

It is important to know what you can get to work.  I think 0.74 and 0.69 will surely work
I think 0.75 and 0.70 may work.

Once we know what works anhd what hash you get and what power you use plus the temp of the gear.

you can decide it doing better then  say 0.75 and 0.70 is worth trying to do.
38242  Bitcoin / Hardware / Re: At what clock rate does an AntMiner S5 mine with peak efficiency? on: April 08, 2015, 05:59:07 PM
Efficiency doesn't change much with clock speed because although dropping the clock reduces power consumption, it also reduces hashrate, and both are approximately linear effects.  The way to boost power efficiency is if you could also undervolt- something that apparently does not work well at all on the S5.

The BM1384 chip on the S5 theoretically allows significant undervolt but even apart from the difficulty of finding high efficiency 8-10V power (required as the S5 is a string miner) the S5 has something which evidently just doesn't work if you drop the voltage much.  Sidehack has said he suspects the (chained) clock line, at any rate some of the chained signals and the related I/O voltages are most likely suspect.  As far as I know no one has taken the time to mod an S5 to be able to undervolt or could tell you what is going wrong for certain.

--
novak

My results are 0.44w/GH par 11.1v
Under 11v. Miner starts but dies after a few minutes.
At 10v and lower, it doesn't start hashing., but you have access to the web interface.
Stock efficiency with the same PSU is 0.54w/GH


I suspect the s-6 will allow good numbers which is why they did not alter the s-5 to allow for a 10 volt psu to attach to the s-5 and work.

What is the lowest freq we can go on a S3 ?? For the summer!  Grin

150 easy.

my batch 1 set of 2 has run 24/7/365 since july 25 of 2014

freq 212  as these did not like to clock high. i can not complain since they have run for just under 9 months so far.
38244  Bitcoin / Mining speculation / Re: Newest Diff thread April 5 to April 18th on: April 08, 2015, 05:29:59 PM
This also allows for  more spec time and less pick time.

I wonder why this drop has happened? guesses anyone?

Or we could just not allow changing the picks Smiley   yeah that works



As for the drop, I'm watching AntPool as usual and it had a few unlucky blocks. If a pool that has ~15-20% of network hashrate takes 8 hours to find a block it does have a visible effect on the charts and estimates.

I think anything within +/- 5% can be safely dismissed as variance. Even that huge hashrate mountain from two weeks ago (~ 50 PH/s) has disappeared now. 25% total difficulty increase in 5 months - we used to get that much every cycle. Exchange rate doesn't seem to be going anywhere either.

variance of + or - 5% is possible.  also clever ddos can hurt hashing we had some brutal ddos attacks around 2 jumps back .

Btw  -1 or -2 is nice for a diff adjustment.
38245  Bitcoin / Pools / Re: [2100 TH] CKPool (kano.is) from the cgminer devs [0.9% PPLNS] on: April 08, 2015, 05:26:38 PM
Hi

I'm mining at night only and 8 hours per day. My electricity cost at night is half of daytime.
Can I expect I would mine 1/3 bitcoins of non stop mining on this pool?

Yes (average expected payout)
Of course luck plays a major part in each single payout, but over time the reward for mining 8 hours a day would expect to average at 1/3 of mining for 24 hours a day.

Edit: In more detail: your shares disappear off the reward list a bit after 500% after you submit them - which at the moment is around 153hrs
it doesn't matter about stop/starting - it's simply that each share will be rewarded in each block found in the ~500% after it.
The value of each share is the same for everyone when the block is found - in proportion to it's difficulty of course.


pretend the time is 144 hours for 500% not 153 hours
so:
in the next 6 days   = 144 hours

 the poster gets ⅓ or 2 days or 48 hours. 

lets say the poster  used 30th  ⅓ = 10th average at the 6 day point   10th miner hash /1900th pool hash =

1 /190  so miner grabs 1/190 x 24.7btc  = or about 0.13 btc  if poster ran the gear 24/7 he or she gets 3x that.


Of course averages aside if the pool:

 does a lot of blocks  = yeh

does very few blocks = meh

does no blocks         = bah
38246  Alternate cryptocurrencies / Pools (Altcoins) / Re: NiceHash multi-algorithm solo mining pool on: April 08, 2015, 05:06:49 PM
I am renting a bit  in the solo pool  I paid for the rental at westhash and it is order number

Order   Type         Status    Price BTC/TH/Day      Remaining BTC      ETA hours      Limited TH/s    Miners    Speed TH/s

It is one more option of renting and mining which is good.

I will still use ck's pool



here I am

http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


and here I am selling hash to nicehash

https://www.nicehash.com/?p=miners&a=1&addr=1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje


If you look at this closely there is a method to what I am doing.

So I like the new option.  I would like very much that a bad btc addy is dealt with in a nicer manner for miners.

I do like that I can use the 3 sites in a way that favors me if I am patient. Most likely my method above will end up how I mine at home.
38247  Alternate cryptocurrencies / Pools (Altcoins) / Re: NiceHash multi-algorithm solo mining pool on: April 08, 2015, 04:53:17 PM
the miner with a wrong address would not find a block as I understand this. I would think his hashrate would be proxied to a subset of wrong hash and no one would know if it was rented if it hit a solo block

 
Here is my rental and I know the address is valid





38248  Alternate cryptocurrencies / Pools (Altcoins) / Re: NiceHash multi-algorithm solo mining pool on: April 08, 2015, 04:50:40 PM




If you enter an invalid address it will be ignored and earnings will be donated to the pool. Make sure you use valid/existing address!


I think I like the way CK has his solo pool set up that if you try and mine with a invalid address your rejected....sure would hate to think someone would find a block only to not get rewarded.

Not to bite the hand that feeds me as I am paid for the signature by nice hash.  I suggest that some invalid address check be used.

Even if  you fill a pot with  coins of 'dumb' miner errors and give it as a promo to anyone mining with you. Each solo block gets half the mistaken coins and you keep the other half.

I will send some hash at your solo pool in a few minutes.
38249  Economy / Computer hardware / Re: Gigampz: Power Supply Kits & Adapters For Bitcoin Mining. Industrial grade. on: April 08, 2015, 04:44:46 PM
We are running low on the server grade kits.  Plenty of Platinum kits left.  We are running a sale on the platinum kits right now for $10 the normal price.  We also have our DPS-2000bb board available for immediate shipping in small quantities.  We expect more CS / Common Slot compatible boards from the factory on April 21st.

http://www.gigampz.com

I am running the platinum with an avalon 4.1

 it is a fraction better on power then my;

 seasonic 1200 watt platinum
 seasonic   750 watt platinum
 evga      1600  watt platinum

I estimate it is            93% at 500 watts
while all my others are 91% at 500 watts

I use 120 volts to run it
It is very quiet pulling 500 watts does not get noisy until the 900 watt level.
38250  Bitcoin / Mining speculation / Re: Newest Diff thread April 5 to April 18th on: April 08, 2015, 04:23:07 PM
Live sheet is back up (mostly) - shows us -3.73% right now.

Some things aren't working quite right (though I believe the standard difficulty projection is) - I expect everything else to be up by tonight or tomorrow, plus a tweaked experimental projection. Last time the experimental projection was decent over the last week, but I have some ideas to make it better.

https://docs.google.com/spreadsheets/d/1qmF2knc5rSrJLESgQJYBz8mPzpKihmSzPPQUGH7pT8g


So we are doing quite nice  a -3 or more would be pretty good.  Thank you for your work.
---------------------------------------------------------------------------------------------------------------------

 Dead line is april 12th 2 am utc time .          

 Which is about april 11th 9 pm EST time.

or april 11th 6 pm PST.
---------------------------------------------------------------------------------------------------------------------
It looks like we will get some changes from the high picks to a negative pick.
______________________________________________________________________________

As a suggestion I think the next contest should wait for 84 hours after diff adjustment to begin.
Then stay open for 84 hours.We still get to see 1 weeks of blocks made and the early rush is put off.
______________________________________________________________________________

I can see that  if we stay low like neg -2 or -3 or -4 percent all the high picks will switch in a day or 2.
A lot of work for me and a bit of confusion.
_______________________________________________________________________________ _

So 14 day period of a block set would be

3 or 4  days of watching no picks---------------- days 1-4

3 or 4 days of picking ---------------------------- days 5-8

then last 6-8 days looking to see the closest--- days 9-14


This also allows for  more spec time and less pick time.

I wonder why this drop has happened? guesses anyone?

We have solo mining service right here



https://bitcointalk.org/index.php?topic=763510.0


run by ck  the writer of cgminer a huge mining program.

fee is small  he has paid 30 plus people off

math to figure odds is easy

2.5th is about 1000 to 1 shot at todays rates for 1 day of mining

so 2 s-5's  = 1000 to 1 each day

as phillip states last block i did almost 19b shares and received under .78 btc due to the fact i had to give up at around 1000 hours and had sold my in house miners degraded from an estimated 4.8 btc to .78 in about 2 weeks i have no shares on current block but still an estimated reward around .47 btc based on previous hash DGM thats why people use this system in conjunction with renting there miners and hashing elsewhere at same time since blocks can be 1 day to 60


yes you  are correct and I left my miner with no hash overnight





23   7c9016f6   2.28519256   0.00504628   126,157,034   0


if you look a few posts  upwards you can see I slipped from 22 to 23 and coins drops from 2.365xxx  to 2.285xxx

but I spent 0 dollars mining. those btc will get lower and lower   if the block lasts really long: " fucked I am" said yoda

If we pop 2 blocks back to back under 30% I do quite well.

As summer gets closer and I sell more and more gear off this pool  gets more play from me.

I had 3 of these connected to a single Raspberry Pi for well over 6 months. I had a single ATX supply for the 12V to these, and the 5V to the Raspberry Pi. It ran un-touched for those 6 months at a steady 96+ Ghash. Supply good power, and a little ventilation and they will run fine, in my experience.

I had 3 of the big ones on a rasp pi and did 390 gh rock steady using a seasonic  psu and ran the rasp pi off a 5 volt cable on the same psu.

The power bricks and not run this gear 24/7/365 unless they read 6 or more amps at 12 volts.

I used to have some 10 amp 12 volt bricks for running gridseed blades  they ran the little round ones you have very well.

how do you calculate the daily chance?

im at about 1.8T
i have 2 S3s at 200M 400ghs and 1 S5 at 325 1.0Ths

https://bitcoinwisdom.com/bitcoin/difficulty

 plug in your hashrate

current adjustment auto pops up and 1.8th earning rate  is 0.01831 btc in a day

25 btc divide by 0.01831 =  1365.374 or close to 1365 to one chance.  This is only a close estimate

my 2.3 th = 0.02339 btc a day or

25 / .02339 =  or 1068  to 1 chance each day  .


until diff adjust moves.

it is fine a lot of big rollers like me are not pointing hash here .  last block I pointed enough hash here to do 10 billion shares  I got 3.5 coin payoff and still lost some coin.  but this pool counts the prior blocks work so that worker has a credit of more then 2 coins

my rank is 22  based on shares this block and my PPS is only 0.00504628  and I am not even hashing
right now.   But my rollover DGM Est is huge  2.36 coins   that is because I spent so much last pool.

follow this worker  the DGM Est will slowly shrink if I don't mine and the PPS will stay frozen. If you look you can see the DGM did already drop just a little.

  I won't mine on this worker for a  day or 2. I am hoping some one hits a block real quick so I can grab those 2+ coins.  then next block.  that dgm est will be 1.5 btc or so If we hit a fast block here I may push a solid rental next block.
