I was under the impression that the transaction fees were also awarded to the miners. So, on the large pools (I use slush, for instance), do they just pocket the transaction fees in addition to the btc "fee" they charge for the block generation?
What's the current transaction fee (on average) per block? Is this something to start being concerned about?

Does 2.0.0 offer any hashing improvements over 1.7.x?
Can someone who has it working answer this? Is it worth the upgrade? thanks. |

Greetings!
I have a dedicated miner that this past year has evolved into a 5830x5 machine. I am looking for a better way to cool it than a series of fans that just pump hot air out into the room. Water cooling 5 gpus would be expensive, and I don't want to have to take apart all 5 of my cards to assemble the rig. Something like a mini AC unit that is 2" by 6" and sits in the case and does the best it can would be awesome. I could just drop it in the case and keep the existing fan structure without heating the room.
Has anyone else accomplished what I am looking to do? How and where do I find the parts?

http://butterflylabs.com/products/Their claims are not outside the realm of physical possibility like some past hardware miner scams have been— but they also don't appear to be possible, at least with current commercially available parts. The webpage is very thin on evidence that they aren't a scam. The most compelling thing I've seen is that they're looking to hire someone who speaks mandarin, though while that bodes well for their honesty it doesn't bode well for their product actually existing.  I understand that a fair number of bitcoiners have sent them money (or, well, that they claim so— but I only know of one). Anyone have any information? It would be a pretty good deal if it were true. I'd like to point out some syntax here. the website says nowhere the hashes apply to BITCOIN MINING. It just says hashes. "Ghash/sec" is still appropriate terminology for hashing for the purposes of decryption. I wouldn't be surprised if this is in fact a generic hashing FPGA, which can achieve these speeds. Whitepixel ( http://blog.zorinaq.com/?e=42) can get 33 Ghash/sec on 4 5970s. That's SHA password hashes, not bitcoin hashes. I'd expect butterflylabs is correct, but they are selling generic SHA hashing FPGAs. It is the bitcoin people who are unfamiliar with the terminology that assumed they were referring to mining. The page says nothing of the sort. |

1.7.0 on ubuntu (11.04) doesn't recognize ^C as escape. I can't reset anything!
Good fix on the disconnect issues. haven't had it anymore. though 1.7 seems to be about 1-2% slower than 1.6.4.
Keep up the good work!

What model 5830? that's pretty impressive. care to share your secrets? phoenix 1.6.4 with phatk2 and overclocked only gets me to about 270. 25% less on your build? That's impressive. Care to share your secrets?  (sorry for the OT tangent) 5830s overclocked (and carefully clock managed, but not overvoltaged, 324MH/s) bought in bulk, 6x to a board, slowest cpu, network booting, a lot of careful tweaking. All other parts cut to a minimum. GPUs screwed to a wooden frame many linear feet long spaced as wide as possible. Ribbons ordered from hong-kong and shipped on the slow boat. I'm also fairly power efficient for a gpu setup— you can gain a fair bit by careful psu selection and running at 240v. (and good power quality is important for stability at high clock rates) Total cost per node are 109*6 (gpus) + 210 (mb) + 4*6 (ribbons) + 60 (cpu/ram) + 100 (power) + 8 (marginal price of a ethernet switch port) = $1056 plus some modest shipping costs and a negligible amount of wood and screws. yields 1944 MH/s. Er. That a bit better than I said, though its a bit closer once you throw in some for shipping. I'm ambivalent about the resale value of the FPGAs. If BTC was no longer viable or you just wanted to get out of the game, I think you would take a much bigger hit on the residual value of the FPGAs than a GPU.
Its hard to say. There are a lot of gpu miners... and once the cards are a couple generations old I expect an influx of used cards (especially a lot of lemon used cards that have been driven hard and not well cooled as many miners are guilty of) will undermine the used market price. It's hard to guess by how much. These ATI GPUs are only so vastly superior to the alternatives for a few apps.. a lot of gamers would rather have nvidia. If you want to build a DES cracker however, then that FPGA will be a pretty smoking solution. I expect the FPGA vendors could probably improve their sales by offering tools for other applications, just to increase customer confidence that the FPGAs are useful for things other than mining. DES reversing and WPA cracking are obvious things that come to mind. ... lack of fast IO limits SDR applications, lack of memory and fast IO limits imaging applications, these are best for crypto. |

I usually mine on Slush's pool, but that went down this morning, so I jumped over to deepbit, which timed out. Then I registered and set up with BTC Guild, and their servers are failing as of about 10 minutes ago.
What the heck is up in the bitcoin pool world today???/

I am poor boy my family just move to country of California. I wish to start mining the bitcoin but I haven't the money to purchase mining rig. I am mine a little bit but only 10 Mhash/s. If you could donate I would be happy to pay you back. Also, my uncle is a wealthy billionaire prince in a Turkish jail. If I can raise the monies to free him he will pay you back 100 times. thanks.
Poor boy forgot his address, send your help to him here: 12A9xBvwZMbDCyszohAki3J721HsCnNbML thanks! fixed my signature. |

Thanks but I want to Solo mine, I have newer hardware that I will eventually put it on when I find a miner I like. If it helps here is a list of the hardware I have available. And for the record I am somewhat of a gambler I would rather take the higher risk option of solo mining for the large payout.
1st Test computer
Athlon 64
Nvidia 8800 GT (AGP)
Any OS option
2nd Test Computer
Turion X2 64x
Radion HD 3200
Any OS run in Virtual Box only
Actual machine after choice is made
Phenom Black 9950 x4
Gigayte HD 6450
Actual Machine 2
Phenom 9950 x4
R HD 4200 + 4700 Hybrid Crossfire
Actual Machine 3
Phenom II x6
R HD 5870
I also have tons of old hardware Mainly P4 Dells that I have configured into a cluster at one point but the electricity use for what I was doing at that time was very much not work the effort. But I might do it again for the fun and challenge if I like mining.
I have GUI Miner on Actual Machine #1 I just couldn't figure it out and when looking for the new version I did not see the link anymore.
dont take this the wrong way, but even with those specs you'd still be at about 90 days average time till finding a block, and the difficulty will change a lot in that time. I'd still recommend a pool. the R HD 6450 will get you about 130 mhash, we'll call it 150 to be nice. the R HD 4xxx series are only beta-compatible with the SDK, and don't post nearly as good speeds (20-40% reduced over the same model from the 5xxx series -- trust me I learned the hard way). 200 mhash combined for this machine. r hd 5870 is the best model you have here and can be pushed to about 400 mhash = a combined strength of 750 mhash/sec. a quick visit to the calculator over at bitcoinpool.com means you're in for a rough road. I'd HIGHLY recommend a pool. you can dare to be great at a 50% chance of absolutely nothing happening, ever, or you can settle for .5 btc a day (at that rate are present difficulty) in a pool, and at least have something to show for it after a month of work. I'd recommend not considering solo mining till your rigs combine to the 4 ghash/sec neighborhood. |

My investments are all in bitcoin rigs, never in any of the so call stock markets or forex exchanges of Bitcoins.
same here. about $800 in parts from ebay along with linux got me to two dedicated rigs for a combined 1.5 Ghash rate. cranks out about 1 btc a day on slush's pool. |

Hi. I am new to the forums but not new to bitcoin mining, win, linux, programming, etc. Any change at a promotion so I can post this myself? If not,
please repost this in the thread: poclbm using CPU 100% even though using GPU?
I have some relevant information here that has not been mentioned yet. I am running identical mining rigs and had a mobo failure and replaced it. both HAD an asus p5k se (read-- cheap) motherboard with miners running sdk 2.1 and catalyst 11.7 for linux (on ubuntu 11.07). replaced dead mobo on miner2 with a gigabyte GA-EP43T-UD3L figuring I could upgrade a little. kept same processor, same GPUs, just upgraded mobo and ram to go with it. now miner2 takes 100% of a core per GPU running. EXACTLY the same everything else. Upgraded to sdk 2.4, reverted to sdk 2.1 and upgraded catalyst 1.8, still no improvements. Tried all these configurations on both poclbm and phoenix miner.
I think the problem is motherboard specific. the gigabyte mobo has 5 pcie slots in total, so I think it may have something to do with the way the Catalyst driver interacts with the south bridge architecture on more advanced motherboards.
Basically, this is solid proof that if it's not working, even on linux, it's not because something is configured wrong, we basically just have to wait for an AMD update.
on a related note, it's ironic that the $10 refurbished mobo from ebay is the one giving me the best performance. heh.
