Bitcoin Discussion Thread Part 2

Pfffftt, I picked up a 2GB 6950 earlier for $180 from craigslist. Better deal imo.

Everyone check craigslist, they have some decent prices once in a while.
 
$180 for a used 2gb card is a good deal, good luck finding more then 1 at that price.
 
I'd love to find a 2gb 6950 for a reasonable price. Damn. Craigslist in my area never has JACK.

Everyone selling around here knows what they can get for their cards. Hard to find a 69XX or 58XX that's not listed for damn near original retail price.
 
Do you guys think it is worth it to start this like in a month or two? I havnt ever done it and i think it sounds neat your getting paid for like a folding thing. Although it seems like it has gone down hill so idk...

I don't know if anyone knows what it will be like in a month or two. As it is, with the increasing difficulty and relatively low exchange, I'm taking a large gamble with my recent purchase of 2 6950s. Assuming the price stays somewhat constant and difficulty doesn't shoot through the roof (I'm praying for a drop, even though it's not gonna happen) I'll hopefully pay off the two cards in between 120-200 days. All of it is a very large *if*. If I pay off one of the cards I'll be happy though because I can sell the other for a decent price and recoup some of the costs.
 
So since i dont have any extra parts laying around its not something i should look into?

if you're wanting to make money, I suggest not.

If you want to sell off your GTX480 and invest in a couple 6970s or something, with the hope that you maybe pay one or both of them off, I think that is more reasonable.
 
Starting up now is much more of a gamble than a couple of weeks ago. Hardware prices have started to give a little but it still requires a not so modest up front investment. We're in a catch 22 situation right now. It is a little too expensive to come in and buy coins to play the market and it is also a bit too much effort/cost to start mining for the relatively smaller return on that investment.

Try the calculator in my sig and put your numbers in to get an rough idea of what you can expect.
 
I just can't wait till winter when I turn every piece of computer hardware I own into data pumping space heaters for both F@H and BtC's. Oh, and I have alot! (mostly just old junk...)

Yup, the savings from not having to use your furnace during the winter would need to be entered into the equation for those of us living in the northern states.

Just set affinity to one CPU, if you're using more than one card it likes to take up multiple cores. Unfortunately there is no other fix. Part of the reason I just sold my 5830.

try running smp 7 on your bigadv client

This will hurt your bigadv times a bit, but they won't get completely screwed up like they can when the GPU and CPU are fighting each other.
 
I have a 555 and unlocked one of the faulty cores and just have Guiminer peg that unlocked one..

hmmm, been reading a bit on smp 7, there seems to be some conflicting information out there. This may be a little OT but I think quite a few of us with AMD cards are folding on the CPU and mining on the GPUs.

I do have both miners set to affinity with the same core (0) but I'm not sure how to configure FAHControl to not use that core. Further, some say that bigadv will not fold on fewer than 8 cores. Others seem to suggest that you just will not be supplied bigadv units with fewer than 8, but once you have the unit onboard you can manually turn off a core to dedicate to GPU overhead. Still others say that this is skirting the rules of folding and there seems to be some controversy.

me confused, only have so much time to sift reams of forum posts

I stopped folding not long after the new client but iirc bigadv wont work with smp 7 and the new client. With the old clients it wasnt an issue.

And to the people who say it's skirting the rules so is using a quad core intel with HT. Honestly as long as the work is getting done right standford doesnt care.

did you stop because of this :confused: the new client isn't even necessary. using the old client you shouldnt have any issues as long as your pc is capable of running bigadv at all

Nope i normally stop folding on my home rigs when it gets hot out. I'll be back up when it gets cool out.
 
I have been backreading these threads and I have to say;

Lorien is one patient individual.
 
whoa

that Phoenix hack just posted 448.59 Mh/s on one of my unlocked 6950s@905Mhz 15Min average on BTCGuild

You need 8 threads in the cpu, it doesn't necessarily mean you have to run all 8 of them at once.
The controversy comes when people talk about forcing bigadv to run on rigs that have less than 8 threads.

So anyway, smp 7 on an 8 thread CPU is fine by all accounts.
 
I have the 2011-07-01 build of guiminer. When I click "new phoenix miner", enter in some info, and click the start mining button, absolutely nothing happens. No error message or anything. It says "stopped" in the lower right hand corner and stays that way.

The standard Open CL option works perfectly and I'm able to do both namecoins and bitcoins no problem.

Out of curiosity, I did a little pencil and paper figuring to determine how good an investment new mining hardware is now. It isn't a horrible idea still, but you'd need to optimize efficiency very well. You'd need to spend as little as possible per hash, and need to live in North Dakota, where the average electricity rate is 5 cents/killowatt and the ambient temperatures are obviously nice and cold. You'd need a huge operation to get the most hashes for your overhead costs.

In my case, I'm small fry - I picked up a couple 6950s that are going to be for personal use when this is all said and done, so I don't have to worry about resale values. They are mounted in my existing hardware.
 
@ Habeed

do you have the bitcoin client on? Has it downloaded the existing blocks? Have you been able to mine with other (non phoenix) miners?
 
Gonna need more info to be able to help you.
- Are you solo or pool mining?
- If you are pool mining did you register at the pool's website and created a worker?
- What's your hardware?
- What version of drivers do you have installed?
- Make sure you downloaded the software from the official page. https://forum.bitcoin.org/index.php?topic=3878.0
Direct link: https://github.com/downloads/Kiv/poclbm/guiminer-20110701.exe

P.S: You don't really need the bitcoin client to be able to mine coins. The client is only needed to receive them and spend them.
 
Lorien : as I said, it works fine for pool mining with the other miners. I did create a worker. Also, even if I had a setting wrong, the OpenCL miner at least gives an error message. Phoenix acts like it doesn't even exist.

That link goes to exactly the one I downloaded.

Drivers : I have the ATI SDK and the latest official (non-beta) drivers. I just set this rig up Monday.

I just tried again. "create new phoenix miner". Cut and paste the info from the Open CL mining account. Leave the flags field blank. Click start mining. Nothing happens. Go to the tab with the Open CL miner. Click start mining. Works right away.
 
I have to say, I have mixed results with Phoenix so far. Got the one card running good, so cloned the config over into a new miner for the other card with the appropriate device# changes and It will not connect...so I'm still OpenCL on one card for a 30Mh/s deficit
 
It's best if you don't use the DEVICE=# flag in the flags field, just select it from the dropdown box and guiminer will do it for you. If you want to see it in action add "-v" without quotes in the extra flags field(works only with Phoenix). That enables the verbose mode and it will spit out everything that goes on with your miner including any errors to the console. To see the console click on View --- Show console.

@Habeed: I can't say I've ever heard of that problem before. Maybe your firewall or malware protection software is blocking Phoenix.exe? Oh I should also mention that if you run MSE (Microsoft security essentials) it will block the bitcoin client from downloading the block chain.

Far from it. Like I've said to others, I'm just paying forward the help I got when I was a noob.
 
Hmm, tempted to grab one or two of those 6970s that Lorien linked. I've got the slots and the power to support them in my existing system. I think my HX1000 Corsair could handle 3 of them if I wanted to get crazy-mode. I can only add 1 to my cart at a time. I can however get 1 of the COD edition OC cards as well as another Powercolor with 880Mhz core for $253.

Lol, impulse buying is fun :D

If it helps any, my two 6970s at 1GHz/340MHz with 1.25v only used 560-570w, and that would be a lot lower if you used air cooling and, say, a single core Sempron.
 
Damn, they canceled the CoD edition card. I guess I only get one for now and it will probably be 6 months no interest. That should give me enough time to recoup my costs.
 
Phoenix is being a pain for me. It can't recognize the # symbol as just a character in my password, and seeing as BTC Guild doesn't allow deleting workers or changing worker passwords I can't use it on my account. So I set up a new BTCG account and made a worker without any special characters and tried to connect. It just sits there trying to connect indefinitely. So I tried the exact same string, substituting the BTCG URL with Slush's Pool and it miraculously works! WTF?

The card is device 0 and the string for BTCG is:
phoenix.exe -k phatk http://leworker_name:lepass@uswest.btcguild.com:8332/ DEVICE=0 VECTORS BFI_INT DEVICE=0 FASTLOOP=false WORKSIZE=128

The Slush string is:
phoenix.exe -k phatk http://leworker_name:lepass@mining.bitcoin.cz:8332/ DEVICE=0 VECTORS BFI_INT DEVICE=0 FASTLOOP=false WORKSIZE=128

The nice thing is I'm getting around 402 MH/s on one Sapphire 6950 2GB which I've got stable overclocked to 930/1350. Does memory freq really make much difference in the hashrate? I've tried dropping it and raising it and it really doesn't seem to affect the rate much. Frequency makes a pretty decent difference though.

But seriously... anyone using Phoenix on BTCG that can help me out?

I've tried both, what I provided above was the full cmd though. It would seem that, except for the kernel used, everything is about the same... *sigh*
