do not mine with graphic card, your btc mined is even less then getting those free bitcoin at https://www.landofbitcoin.com/?r=phqCKSzE8j0J1vMW
get asic miner, usd 50 might get you a s1 if u bargain hard

haha an S1 for $50...
 imagine someone being that dumb...
cuz you know you cant buy an upgrade kit for them to make them S3's... no really you cant just yet Wink

maybe a Block eruptor Cube, those are only worth $50. s1's lil under $150 at x5 the hashing rate
wow funniest thing on ebay is people selling corsair 500+'s with a cube for under $50... the power supply is that value! nice deals if you can snag it!



I got a couple Antminer S1's for about $70 a pop after lots of bargain hunting.  Amazing what you find when people misspell stuff.  I used to find the usb block erupters for dirt cheap cause they would spell it block eruptOr.  Search and you shall find.  Also amazing what you can find on craigslist too got an Antminer S2 for $650 once.

JT
Myself as well. I was able to buy a single S1 + PSU for $110, as then two more for 0.065 each.

@Billbags, it was probably found right after another block, so there were no new transactions to include. It happens once and awhile.

So a block includes these 4 things:

1. A set of transactions
2. A timestamp
3. The 256-bit hash of the preceeding block
4. A nonce sufficient to make the hash of the block not exceed the current target

I now assume the transaction amount could be ZERO if that's the number needed in the control theorys feedback loop to ensure the proper amount of time a block needs to be completed to get 2016 blocks every 2 weeks.

Update: If someone could confirm or disprove this, it would be appreciated greatly. I can't find that transaction figures would deal with time in the block equations, so my theory on zero transactions may be false.

60minhr∗24hrday∗7dayweek 10minblock=2016 in 2weeks

Tcurrent=Tprior∗tprior/2weeks

D=work/2(32)=2(256)/(Tcurrent+1)∗2(32)

hashes/second≈D∗2(32)/600

Update:
To validate a block, a node checks several things including that the block’s hash does not exceed the current target, that the timestamp inside the block is not too far in the future or the past, and that all transactions inside the block are valid. So now I'm assuming zero transactions = no invalid transactions. This would make the node accept the block and cue it to be confirmed while transmitting it to the other nodes.

Last Update:
I had totally forgotten the fact that transactions happen everyday without fees, so I now realize that a block with no transaction FEES doesn't mean there wasn't any transactions and most importantly a block can be solved with zero transactions. Sorry for the madness, just trying to understand block #317553.Time to log off, relax and enjoy the pools good luck for awhile.

I found the following block while mining with slush.

https://blockchain.info/block/000000000000000014bf07c25415110d1d565cc60db69f5acb3743843ede2937?site=slush

It had 0 transactions. Too bad I wasn't solo mining Smiley

Correction. It had 1 transaction - the 25 BTC award.

Why does the Bitcoin system allow for blocks with 0 transactions?

Why not?
Bitcoin system is set to produce a block every ~10min with or without transactions in case there are none as it was in it's first days. The first transaction ever is in block 170 should we loose 169 blocks because there are no transactions?

If you don't mind me asking, how much hashpower were you pointing at Slush's when you found that block?

Also, congrats on finding the block!

I had, and still running, 8 overclocked S1s for a total of 1.6 Th/s. One of the nice things about slush is that it lets you know and keeps track of blocks found by your miners in your user stats. I've never seen that at other pools.

One of the bad things is when you lose internet service, like a lot of TW customers did this morning, your shares can shrivel away. I wish they would change that. I don't think pool hopping that big a deal.

I agree and it's not just an unexpected loss of internet.

Taking one or more of your miners down for  " maintenance" or " re-arranging "  can and will cost you.

I dont know the ins and outs of pool hopping but I think regular users shouldn't be penalized.

Why would you reset them so much? Or at all for that matter.

my 2x antminers s3 batch6 seem to be running very unstable for me, when I first start them cold they run fine for many random amount of hours or days, and then suddenly losing 6-7% of power (from 440 Gh/s to 410 Gh/s), I have been experimenting alot, cleaning the heatsinks, running open/closed case, reversing both fans, keeping room they are in as cool as possible, but they seem to be doing that no matter what I try. restarting cgminer seems to be keeping AVG hash rate up.

Well I think you may be causing some of the problems your self.
1st thing you want to do is set the machine up and LET IT RUN for 24 hrs.
These machines do vary in speed.  Dont watch the present speed you want to watch the AVERAGE speed on the ANTMINERS.
trying to react to every small variation can lead you down the wrong road.
I have 6 S3's and they do vary in speed but after TIME they all average out.

Take a step back and let your machine run for a while before you go chasing a problem that's not really there.

Take it from someone who learned the hard way...

Also machine speed on the GUI it not always reported as accurate at it could be.

What is your " POOL" reporting ?

I have one small klondike 5-6Gh/s (donnu how to overclock it Smiley I bought first one to play with it.
When I restart first time it drops half speed, when I restart again it wont start up, only shutting down it and disconnection from electricity helps...
And last two days, one of two S1 after booting cold simple don`t start to mine (not showing speed in gui) after I change speed in file and rebooting it starts again. Simple restart don`t work. Working temp. 43-45c.

I am not taking antminer status page that much into account, but am looking at pool stats.
I have been running miners for 2 weeks now. The problem is with only one of the units, they both are not similar, they have different heatsink design, fans on good one are really loud and running 1980RPMs AVG one temp sensor shows 40, other 35, the bad one is very silent and fans run at 1620AVG, both temp sensors show 38 degrees.
when I first started the bad one, it ran at 440 GH/s avg for about 12 hours, then took a dip to 400 AVG for 8 hours and back to 440 for 3 hours. Then there was a power outage in my area for 1 hour, after power came back it started hashing 400 AVG for 30 hours non stop. I came home and tried to reboot for several times, it did not help (10 minute AVG was showing 400-420 GH/s). Then tried to reset to factory defaults, which fixed the issue for 6 hours hashing at expected rate, then it went back to 400 GH/s AVG (for no appearent reason). One morning I reset to factory defaults again, it hashed at 440 GH/s for a short period of time (30-60 minutes) and then it was back to 400 GH/s for 8 hours. There are no X showing in miner status, temperature is lower than the other miner I have (which runs 440 avg no matter what). Acceptance rate / rejects ratio are very similar. After seeing it run slow for 30 hours non stop I am not letting it do this anymore, instead I am trying different things with it - one of which is auto cgminer restart.

edit: by the way, I have found at least 2 people on this forum reporting this same exact symptoms as I have and are auto restarting as well.

Well forget about temperature, these things can run at 50c with no problem, I know because I had 3 running down in Florida in the spring and had no i'll effects.
What pool are you mining at ?

I am 90% on Eligius, but have tried Slush, Ghash, Discus Fish - all of them report same behavior.
The only pool I am getting stable hash rate on bad unit is solopool.net. Only difference I can see is that most pools will set difficulty to 256 or 1024, but solopool is setting it to 50, but I do not feel lucky enough to mine there.
