Cryptocoin Mining?

[Avalon]

I'm on my iPhone so searching this thread is pretty tough. I got my miner going but can't seem to figure out how I sync my bit coin wallet to the pool I joined so I can get paid (eventually)

Little help?

In GUIminer or cgminer, there are options to specify your pool's address. For example, with coinotron, I think their address for bitcoins is http://coinotron.com:3333. If you run cgminer via batch or command line, you have to specify the -o option and then provide your pool info. If you run the exe directly, I believe both will prompt you for your pool.

Could never figure out how to setup a bitcoin client.

Anyone know how or can point a decent guide on how to run AMD cards from different generations in the same box? I'm going to consolidate some of my miners from 4 computers to two with a mix of 5xxx, 6xxx, and 7xxx series cards. Is it plug and play and CGMiner can automatically make use of the hardware or are there some extra steps? I'll find out later today but just wondering if anyone's had experience with it.

For about 3 days, I had a 6950 mining with some 7970s in the same box. The only thing I had to do was set the 6950 clocks independently. I use Guiminer, so each miner has it's own tab, with it's own flags and settings. There was nothing more to it for me.

Yes if you use CGMiner, it should detect the cards and use them automatically. Diablominer did the same for me while running a 6950 and 7950.
If all else fails, use a different instance of cgminer/diablominer/whatever for each generation of card or even each card, enabling only the card you want for that particular instance.

So I tried both of these and I'm getting errors from the 5850 I'm currently running (haven't tried any other card yet) with the system in my sig. The 5850 runs fine and plays games and everything with no sweat, but I keep getting "invalid nonce - HW error" errors without any nonces finishing. I'm wondering if it's a software issue since I'm on 13.3 betas.

I think it's software only, I tested my 5850 on windows 8, with 13.3 and SDK 2.8 and 2.5 (or 2.6?), and I had the same "hw error" warning, so I loaded my Windows XP install with 11.12 driver and it worked fine at around 300MH/s with no error.

 

[Piotrsama]

^ and ^^

I had the same problem.... only Phoenix 2 is working fine on Win 8. (cats 13.3 beta 3)
Guiminer (poclbm) and cgminer are a no go, and didn't try others.

Also, had troubles installing SDK 2.8 (error trying to install, and sizes of the SDK modules were way smaller than they should.. like 20MB), so I'm using 2.7.
Same performance with 2.7 or 2.6... didn't try any older.

 

[Chiropteran]

All you need is drivers and a miner program if you are mining with cgminer or guiminer (or reaper for ltc). If you want to use diablominer you also need java installed.

I haven't had any problems mining with windows 8 or any other OS with the 13.1 drivers.

 

[JoeMcJoe]

Are any meaningful calculations being performed while 'mining'?
Or is just complicated number crunching for the sake of crunching?

I'm on Windows 7 64-bit. This 5850 is the only card that would fit well in my main box (in sig), so I'm trying to make this work. I've tried CGMiner, separate instances of CGMiner, GUIMiner (which runs poclbm I believe), Phoenix, and DiabloMiner. Nothing seems to run the 5850.

Are you running a 5850?

Yeah, two of them on one of my dedicated miners.

What are the flags you are running? Flags for a 7 series may not work with a 5/6 series.

 

[hokies83]

Got 23$ for my last sell of 1/10th a bitcoin on Ebay thats like 220$ a coin XD

 

[MrK6]

For combined that's probably so, but even if I run a cgminer instance with the -d 1 flag (pointing it to run the 5850 only) I still get the same issue. It won't produce a valid nonce.

May well be a driver issue then. I think most people on 5 series cards ran 12.6-12.8 drivers IIRC. Google for a 5850 setup and try it...if it doesn't work then it could be drivers. Look here:
https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMD

Gives a lot of working setup options.

For those of you mining litecoins (or trying to figure it out), the latest version of cgminer has a much improved scrypt-readme.txt file. I HIGHLY recommend reading it thoroughly.

Oh, and litecoin mining is for masochists. It's MUCH more difficult to tweak than bitcoins!

Mining is used to validate transactions.
http://en.wikipedia.org/wiki/Bitcoin

The transaction log is authenticated by end-users through hashed ECDSA digital signatures (similar to a username and password) and added to through calculations of varying difficulty, performed by dedicated servers called bitcoin miners. Each 10-minute portion or "block" of the transaction log has an assigned amount of bitcoins that is awarded to miners (who can then sell them at their discretion) once it is added to the log and confirmed by other miners.

The full paper that describes the system is here - this is the original paper that started the whole thing:

My litecoin p2pool node has been generating dead and orphaned shares for about 6 hours. Anyone use p2pool experiencing issues?

 

[arkcom]

Seems it was just bad luck. If anyone wants on my node send me a pm.

Anyone know how litecoin transaction fees are calculated? I'm trying to send 1.5 litecoins and the client wants .5 litecoin transaction fee. Seems ridiculous. If I had the coins to cover the fee would it at least inform me before charging it?

 

[Silverforce11]

Just started, finally.

7950 @ 1.2ghz and 300 vram downclock, 1.15vcore (!), getting 597Mha/s (614Mha/s peak) with GUIMiner.. that sounds about right?

Not sure if you USA guys have picked up on this but..........................

As someone in the UK who has traded forex since 2010 I have noticed something....................

BTC-E-USD ask price = $171.50 (Ask is the price you buy at, bid + spread)

MT.Gox-USD bid price = $182.00 (Bid price is the price you sell at)

So, assuming free or low BTC transaction cost to transfer BTC from BTC-E wallet to Mt.Gox wallet, then you can now deposit $857.50 into BTC-E account, buy 5 BTC, transfer them to Mt.Gox. Sell all five for $910. Withdraw the $910 back into a USA account (however you do this?) and pocket $52.50. Rinse and repeat all day long as long as the gap exists! No hardware to buy or electricity to pay and you just use the same $1000 you started with all day long.

Only thing i'm not sure of is the total transaction costs to ;

A) Get USD into BTC-E and Buy BTC?
B) transfer BTC from BTC=E wallet to Mt.Gox wallet?
C) Sell BTC on Mt.Gox into USD?
D) Withdraw USD from Mt.Gox into USA account?

Now lets guess these costs total say, $20, you would still be $32.50 up on each set of trades, and I guess you could do maybe 1 trade every 15 mins or less with BTC confirmation times?

This is absolutely no use to me in the UK and fees to get money into BTC-E are high and there is no way for me to exit into GBP from Mt-Gox.

Food for thought my USA friends. Anyone USA based with both BTC-E and Mt-Gox accounts care to put some true transaction figures to this for us?

Because if it can work, I for one may apply in the UK to open a uk based $ USD commercial account to do this as a side profit to mining.

AT LEAST AN hour to clear each time you move it.

So for arguements sake you could achieve this at least once a day? And any idea of the various transaction fees involved?

I have noticed on the Mt.Gox site that USD withdrawals via Dwolla are only $0.25 per transaction. That would be cheap from moving almost $1000 out. No idea of the Dwolla fees to get that into a USD based account though?

Hey just thought, can you deposit USD into BTC-E with Dwolla? That would save time!
