I want to know if someone can clear up a question about all of the usernames/passwords that are needed to get started.

When I install the client (maybe it is not needed if I am installing a miner?) I need to set up an rpcuser & pass.

When I join a pool, I will set up another username + pass.

The pool wants me to have a worker username + pass

Finally, if I have a Mt Gox acct, I assume I will need another username + pass.

Of these 4, do any of the usernames/passwords need to match up for the programs to run or me to get credited correctly, or should they all be unique? Does the wallet have a password involved, or is it the pool's account info the password that is commonly mentioned that needs to have a strong password? Sorry for all of the questions, just cannot find a clear distinction on the bitcoin forums.

Yeah, lots of accounts to be created at lots of places.

As far as the bitcoin client itself, as long as you're joining a pool, you don't need to create a username and password.

But yes, for any pool requiring registration, you'll have to create account credentials for that pool then likely create credentials for each worker (you then use the worker credentials in your mining program to connect each worker to the pool).

And for Mt. Gox, or whichever exchange you use, you'll have to create credentials.

Your wallet doesn't really have a password. Its security is based on matching up of a pair of hash keys (one is the public key "address" you use for sending and receiving coins and the other is stored in your wallet.dat file). Lose your wallet.dat file and your coins are gone...proper fucked, Tommy.

So to maintain security and safety of your wallet, you'll want to make regular secure backups of your wallet.dat file and store them somewhere safe and secure (I create encrypted 7z files and e-mail them to myself on my Gmail account).
 
A question about the wallets. Does the miner create the wallet.dat file or is it the bitcoin exe that creates it? I found one in the users/appdata/roaming/bitcoin folder on my computer (vista) and wasnt sure if that was the real one as it's just full of jibberish (not even a has code, but like symbols and randomness). Do i need to wait for my first full bitcoin to get a hash?
 
Meh, the Silk Road is just an excuse to go after the real threat, people being able to exchange goods and services without the money masters making a profit off of it for doing nothing.

bitcoin.exe creates it. The miner wont interact with it at all. Be sure to back it up. Its your piggy bank.
 
is there a simple walkthrough for how to set this up, either with or without a pool? im really busy for the next week or two and trying to set it up last night took me way too long. (didnt help that my stupid internet wanted a couple hours to download guiminer) i really want to put my idle 5870 to use.
 
While every other dolt bends over backwards quoting articles hoping this crashes because they were too lazy and/or stupid to figure it out, I've already cashed out >$500 in liquid cash after electricity costs and fees after only 2 weeks of mining. I only wish I hadn't dismissed this as a pyramid scheme when I first heard of it 2 months ago. I'd be up at least $3k by now.
 
Anyone know if there is a site or program like EOC for folding or Free-DC stats for this? I always like graphs for trackign DC stuff.
 
id just a hard pool also
i have a tri cross fire mobo, if i put a 6950 in there and a 4850, i can use those to mine correct?
 
Yes, you would either have to hook up a monitor to the 4850 or a dummy VGA plug so the PC recognizes it as a separate GPU. But the 4850 only does about 100mhs which with a generic BTC calculator, says it would only produce ~$30/mo in a pool.

These stats are usually provided by the pool that you're in.

Mining with the 4850 is probably not worth it. Either retire it or sell it and invest in a 5xxx or 6xxx card.

There is definitely enough interest in the pool so I will start setting it up tonight. It should be up and running in a few days if everything goes smoothly.
 
I asked this in another thread, and got an answer that got me a bit paranoid. How fast is this likely to kill the cards doing it? My rig has good cooling but I havent yet had the balls to just leave my card run all day when Im not there.
 
does anyone else have the bitcoin logo for the [H] logo in their browser right now? anyone know the reason for this?

I assume this is no different then any other DC project, in that if you have adequate cooling, the components should be fine. This is also assuming you have a quality PSU. I don't specifically remember the temps for different GPUs, but I would say if you are in the low 80s under full load, it is fine to leave unattended.

I ran it for a few hours last night, max temp I hit was 78c, mostly stayed at 77. Fan was only at 32%. My rig is built solid, I have no doubts about that - Antec 750w PSU along with sig components, and the card is an AMD, no branding.

I just get really nervous leaving the card at 99% load constantly. I dont know if its likely to wear out in a week or 5 years.
 
This seems ridiculously hard to set up.

What would I need to do to get going with my 2x 6970 setup? Is there a comprehensible step by step guide?

Sign up at your choice of pools, install guiminer, enter login info, choose your mining device on the default menu, and hit "start mining". It's ridiculously simple, actually. The hardest part is deciding which pool to join, or if you want to go solo. Once the [H] pool is running that should make it a no-brainer.

Thanks, that's a hell of a lot easier than trying to understand the guide.

I think I'm set up and running correctly. If you can help me confirm this it would be awesome.

I first downloaded the bitcoin.org client to get my wallet address.
Then I signed up for BT Guild and pasted my wallet address into it. I created a worker, downloaded guiminer, and plugged in the details. I have two clients running, one for each GPU each putting out about 350 mhash/s.

Does the payout happen automatically? What's the rough return per week I'll have with 2 cards at 350mhash each?

Thanks so much.

First off, I had stability issues using drivers newer than 11.3, so I'd suggest using those. If this is your main rig, you'll also want to disable hardware acceleration in Flash player as playing any sort of Flash video will most likely crash your computer if you don't.

Download GUIminer: http://forum.bitcoin.org/?topic=3878.0

Go to BTC Guild and register: http://www.btcguild.com/
I'd also register two workers, one for each card.

Start up GUIminer and choose new OpenCL miner.
Choose BTC Guild from the pool pull-down, and enter the login and password for your first worker. Make sure you choose your first card from the device pulldown.
For extra flags, put in: -w128 -v -f10 (that should work pretty well for you as that's what I run on my 6950 with unlocked shaders)
You can probably go with a higher -f value if you're seeing desktop performance issues, but anything higher than 10 and hash rate drops off quite a bit while Folding on mine.

Repeat for your second card.

Start 'em up!

Eventually, you'll want to download the standard bitcoin client so you can get your coins from BTC Guild: http://bitcoin.org/
Just start up the client and it will automatically generate a wallet.dat for you and give you your first address. Plug that address into BTC Guild under wallet, then you'll be able to send yourself your generated coins.

Awesome, thanks so much. Didn't realize I needed two workers for each card.

What kind of payout are you seeing with your rig?

Click to expand...

Your rewards will accumulate automatically on BTC Guild. Once it gets to a reasonable level, just click the button to send them to the address you input.

You should be able to do about 9 coins a week, or just over a coin a day, with those two cards...at current difficulty.

Well, you don't *need* a worker for each card, but it helps for tracking the performance of each card.

My 6950 (clocked at 850/800) with the settings I posted above does right around 365MH/s, so it would be doing just a wee bit more than one of your 6970s. With the 11.5b drivers, I was able to get it up to about 390MH/s, but it was way too unstable for use as my main rig.

where are you getting that you need two workers for each card...? is it a multi gpu card...? I have one worker for each of my gpus (3)...

I get about 500MH/s so a little less than 1 BTC a day, 25 or so for the month...
 
thax said:
unless you have a shit load of Mhs you wont make anything solo i heard
Click to expand...

You'll make coins at the same rate. However, it would be totally feast or famine. If you were running on one 350MH/s card, for example, it would take an average of almost 3 months to generate a block at current difficulty. However, when you did generate that block, you would be sitting on a whopping 50 BTC.
 
oh ok
one more, thanks for the answers btw
if i were to run a 6950 as my main and install a 460 gtx (for cuda on Adobe Premiere) Could i use both for mining or atleast the 6950 for mining and the 460gtx for work? thanks!
 
after looking at the numbers [H]ere in the estimate thread it's not very promising, at that kind of rate it will take a while for payouts, we'd probably have about 1/200th the hashing power of the biggest pool (Deepbit) and the payouts would be considerably less often than any of the already established pools, and considering that this is extremely time sensitive (if you start right now the majority of bitcoins you would generate with your rig in it's lifetime, about 90% or so, will be generated in the next 4 - 6 months), we just won't have the hashing power to really compete with a competitive payout rate compared to what other pools could give during the most productive months of this, with each difficulty increase the payouts get less and less frequent in pools, even the bigger ones...

Yeah I kinda figured it would turn out like that since you'd be starting fresh from the ground up. It's going to be pretty hard to compete with the power of the stablished pools, for example Slush's pool (my main choice) is up to 1.4Tera Hash/s and Deepbit is at 2.4 Tera Hash/s but they've been getting DDOS'd lately so I'm staying away from them.
 
Is it normal for one card to be higher than the other?

I have crossfire enabled.

Card one is showing 400 mhash/s and card 2 is around 350. I'm checking these stats from the BTC Guild website.

That just means one card has been luckier than the other at finding shares. For the real hash rate, definitely go by your client output.
 
Hashin' right along at 336khash/sec on the 5850 after some OC'ing and tweaking... might sell some spare parts for another 5850 and pump out the cash
 
Regarding the question about work size in the hash rate thread (let's keep that thread on topic, folks, and keep the discussion in this one)...

Try both -w128 and -w256 and see what performs better. Personally, my 6950 does better on 128 and my 5830s do better on 256.

How much of a difference will one see out of these changes? Are we talking 10MH or more?

I just changed from no flag to 256 and i'm not really seeing a difference
 
Got up to 390mhash on both my cards! This is fun, something that actually makes overclocking worthwhile.

Not very promising? I don't see the problem. At current difficulty with 8GH/s, we should average two blocks a week. I'm sure more people will join in as time goes on to counteract the difficulty increase, so I don't really see us dropping below that block rate.

Of course, there are a lot of good pools out there already with little to no fees.

I'd just suggest staying away from deepbit. While it's a great pool, it's a little too big for its britches.
 
Here's another question for you guys - I assume most people are doing this on their main rig? Do you just turn off the miner when you're gaming or doing high-workload stuff and leave it on for browsing and stuff? I have 2 other rigs I could set for mining but they wouldnt be worth it at all. Old hardware.
