I've tried this on a couple windows 7 machines now. bitcoin -server with a bitcoin conf specifying username/password/port/allowed ip simply doesn't work. I can connect to http://127.0.0.1:8332 and it prompts for a username and password but returns a page not found... this should be dumping something in json format yes? rpcminer pointed to that address with correct user and password parameters just says it can't retrieve work. As far as I know there isn't a web interface. Are you sure there's not something else running on that port? Vmware Server? |

How about you spare the newbies the rhetoric about things they don't know about or understand.
How about you lose the bad attitude. I might if your intention was to be helpful in any way instead of making a statement that hardly makes sense to someone who isn't even mining yet. If you don't want newbies going to deepbit and slush then give them a real reason not to, not a completely useless statement as to why not. |

Why are you mining?
The only real advantage of using the largest pools is seeing your balance go up every five minutes. But it's better for network security to use smaller pools.
How about you spare the newbies the rhetoric before they start mining. All you have to say is that there are plenty of other smaller pools that they can check out other than deepbit or slush. I suppose the best thing will be to test it when my cards arrive.
I'll run them both in one pool for one week then both in another pool for another week and then split them for the final week. I'll probably use slush's and deepbit. They seem to be the most popular and reliable as far as I can see. Unless anyone has any other pool suggestions.
There's lots of pools. Bitcoinpool.com and btcguild.com and btcmine.com have no fees. |

Does a 50% increase in diffuculty directly translate to 50% increase harder to mine? So 2BTC/day would go to 1BTC/day? What's the proportion?
Yea, think so. 100% increase would make it twice as hard to mine, not 50%. Say the difficulty went up 50% from 244,000 to 366,000. 366,000 - 244,000 = 122,000 366,000 / 122,000 = .333 or 1/3 harder |

Hi all, just checking back after I went to my local store. I can't find anything in my list from newegg -.-||| So I have to go for similar stuff. This is what I have right now.

Because I'm very new and am just picking stuff up from the forum. I'm not sure if I'm doing the right calculations. Thanks  and do comment on my rigs. P.S Oh I forgot to factor in the PSU efficiency sorry so assuming it's 80+ Ready @ 80% minimum theres a x1.25 factor to the figures I'm using for both upper ($9.30/day) and lower limit ($6.024/day). Theres a +1~2 Days difference so I'm sitting on 45 Days till breakeven. P.P.S The price for 5970 is low because I've got a deal from someone I know. I'm getting 2x this rig so instead of putting both of them in 1, I decided to separate the power distribution. Please advice on this too Parts look good and calculations look correct. You also break even faster if the price of bitcoins goes up too. I originally planned on breaking even in 80-90 days, but I broke even in about 35 because the price went up so much. Too bad I didn't hold on longer or I could have more than doubled my money if I knew bitcoins were going to go as high as they did. |

I don't speak Hebrew or know what the exchange rates between currencies are, but everything looks compatible and the price is about right according to the items you listed.
cool thanks alot. now i need to convince some of my friends to chip in with the investment . i dunno if it will help cooling the gpu but i did order 1 PCI slot fan to put as extra air just in case i might play with overclocking a bit ( nothing extreme though. The PCI slot cooler is not even worth it with multiple video cards. I can't find anything that shows the layout of the inside of that case. From the picture on the website it doesn't look like it has any cooling from the side and doesn't look like it has more than 1 input fan in front and probably 1 output fan in back. With that case you can almost certainly plan on having to leave the side panel off to get enough airflow to the cards if that is in fact the layout. |

If I had two 5870's, mining 24/7 at about 350 Mhash/s each, what do people feel would be the better mining option?
A) Pick a pool and have both GPU's mining in the same pool constantly.
B) Pick 2 pools and have one GPU mining in each pool constantly.
C) Solo mining.
From what I read using pools in some way would be better than solo mining for the amount of Mhash/s I will be able to utilise (correct me if I'm wrong). I personaly was going to go with option B as I felt mining from two pools would help compensate for either pool having any unexpected down time or one pool having a bad day for whatever reason.
Any thoughts?
Running 2 GPU's in different pools would help minimize variance a little, but you're going to be hard pressed to find 2 pools at the same speed. I would say put them both in 1 decent sized pool. If you double your speed then consider splitting it between 2 pools. Solo is a personal choice, but @ 700 Mh/s you're looking at an average of 17.33 day to find a block. Probably not worth it. So why would I need two pools at the same speed? And by speed do you mean the overall Mhash/s of each pool? It's just a psychological thing. If you're in 1 pool that's 50 MH/s and another that's 100 MH/s you're only going to get half as much from the bigger pool, though theoretically you should get it twice as often. |
|
|

nvm, it's much higher now so it should break even
I think the whole site swings back and forth because mine is up ~60 MH now. The only thing that matter is when your Estimated Rewards changes, well, down at least. I don't think anyone will complain about it going up. |

I'm getting idles here on my system. start /DC:\Bitcoin\phoenix phoenix -v -u http://xxxxxxxxxxxxx@btcguild.com:8332/;askrate=1 -k phatk device=1 WORKSIZE=128 VECTORS BFI_INT AGGRESSION=13 FASTLOOP=FALSE Without askrate I was getting lots of idles if only for a short period (<1s it seems). I put on askrate=10 and it helped but had to keep reducing it to =1, and now I still get a few but not as many. This is on a dual 5870 system, while my 2 5850 systems don't seem to be having this problem at all. I was at slush's pool before this and never saw any idles, could this be due to the LP or is it something else? Askrate is not necessary with Phoenix because it maintains a work queue and only requests work when needed. Phoenix also ignores the askrate setting automatically for RPC servers with long polling support. Hmmm thanks. What do you suggest I do about it? Shouldn't phoenix have a queue of work so that it doesn't have to go idle? Remove the askrate. The miner is idle errors is a bug they are still working out. They think they might have finally figured it out and it will hopefully finally be squashed in the next release. Make sure you are running the most current version 1.48 http://forum.bitcoin.org/index.php?topic=6458.0 or if you are still getting excessive idles try GUIminer http://forum.bitcoin.org/index.php?topic=3878.0 or poclbm. |

I had to escape the ;askrate on linux or else OpenCL would say it couldn't find the device. phoenix -u http://USERNAME.WORKERNAME:PASSWORD@mining.bitcoin.cz:8332/\;askrate=12 -k poclbm DEVICE=2 VECTORS AGGRESSION=12 Standard poclbm/poclbm-mod were giving me 317Mh/s. Phoenix was giving me 310Mh/s. That went up to 343.5Mh/s with BFI_INT! If you're using askrate make sure to set it properly. Calculate (type into Google) 2^32 divided by your hashrate. So mine would be 2^32/343500000=12.5035438 (so 12) Nice to see that BFI_INT is working for you! As for askrate, it's not necessary with Phoenix because it maintains a work queue and only requests work when needed. Phoenix also ignores the askrate setting automatically for RPC servers with long polling support. "The worker hash rates shown below are estimates based on share submissions in the last 15 minutes. These will rarely be the same as your miner's actual hash rate." Wait a while and see if it improves. Right now my Total Worker Speed says it's 30 Mh/s slower than I know it is. I've seen it show 100 Mh/s higher at times also. It's going to fluctuate, it's really not anything to worry about. |

I was thinking about this, can someone answer..
Even if he has 7.5Gh total, each card is still only giving him 600Mh. Since not all the cards are working on the same block, wouldn't it actually take something like 20 days (according to the calculator) to solve like 24 blocks? Instead of one a day. In reality, each core of each card is still working by itself on a block right..?
um, no. Each GPU gets it's own work and they all work toward solving the current block. |

Website shows that I mine at 600-700 mhash, even though my miner shows 760-780, why are there so big differences ? Does it mean I get paid for 600-700 mhashes ?
You get paid according to the percentage of shares you submit divided by the overall shares. Shares aren't computed at a constant rate, some take your card longer, some shorter. The server isn't told how fast your card works so it calculates your speed as best it can according to the shares you submit. Sometimes it will show faster, sometimes it will show slower depending on how long it takes to complete calculations and submit to the server. |

Anything over the base cost, plus some profit, plus the freedom of anonymous payments, puts the bitcoins real value at somewhere around $0.25 to $0.50
Do you have any hard technical data you'd like to share to support this assertion or is it all from your rectal knowledge base? the $5 - $8 figure we are seeing is because of pure speculation, it has nothing to do with 'demand' of bitcoins since anything you can buy with them can be bought with normal dollars.
Since there are no futures contracts and the prices on the exchange are what people are actually trading BTC for cash, speculation doesn't have anything to do with it. It may or may not be overvalued but the market will determine that. |

Hi all, new to these forums.
I'm having a problem with my miner, when I try to use the batch file I wrote I get an error message saying 'Windows cannot find host= deepbit.net' .
Heres the miner
start /DC:\poclbm\poclbm.exe --host=deepbit.net --port=8332 --user=xxxxx --pass=xxxxxx --device=0
any ideas? Thanks in advance
You need a space between poclbm\ and poclbm.exe start /DC:\poclbm\ poclbm.exe --host=deepbit.net --port=8332 --user=xxxxx --pass=xxxxxx --device=0 |

Anyone saying he should go solo...
Probably never have studied statistics...
Or are just some degen gambler...
Go read up on Poisson distribution...
You be suprised how huge variance is...
He could mine for week++ with no blocks...
At this difficulty level...
Actually going solo...
Could break his operation...
Unless he is degen gambler...
3% for reduced variance is nothing here...
If he mines 8.5=10 Gh/s his average for hitting a block is around 1.5 days. Going a full week or more without hitting a block would be statistically insane. If I had half speed I would go solo instantly. As Vladamir said, the hardest part is not sitting there watching it every minute and worrying that it's not getting anything. |

Yes, and with difficulty expected to rise 50% soon, mining is going to come to an end for a lot of people. Unfortunately most of them probably don't know it. It may take some time for some of them to figure it out, and some probably won't. Those types will (hopefully) get frustrated or bored eventually. Then there are the believers who run the hardware despite profit just to add something toward secure the network, though I'm sure they are quite a smaller percentage currently. |

I'm not too familiar with the 57xx series. Have you tried any of the overclocking programs or are you just running the card with the stock speeds?
Do you have other programs running on your computer when you're running the mining software?
I've tried both catalyst and afterburner. getting no difference in any - well I'm using utorrent, skype, chrome and messenger and ofcourse bitcoin server and the two consoles with phoenix and for my 6850 poclbm.exe. using like 2 gb ram out of 6. Skype and Chrome both use video card resources. Depending on what messenger you're using it might use flash for ads and flash has the ability to access video card resources to speed up processing. Try closing all of them and running it without them all. Anything accessing video resources can impact mining speed. |
