I currently have x2 270's and x2 280s' and x1 290. Given that you can buy a 270 for ~200 that can do 450Kh/s and is 125 watt. I was thinking that we are better off with 2 450+Kh/s for $400 than 1 280 that does 750KH/s and pulls 250 watts. Anyone have any thoughts?
I'm confused, hopefully someone can help me. My Bitminter says I'm running at 8825 khps with a crappy old GT 420 graphics card. (nvidia) When I see a new card that runs at 750kh/s it looks to me like the crap one I'm running is faster. I know I'm definitely missing something here. What is it? Are you certain it's khp/s or just hp/s? If it is claiming that, your not really doing that. Bitminter will show the accepted share computation on the site. |

Though the heatsicks are pretty, they are also not that effective. The whole back of the card is a heatsink, adding a few ridges to the other side won't make much of a difference. I guess you could maybe push 2.5 with advanced cooling, but I really doubt getting 4 would be do'able. |

I bought 4 of these little devils  Got them at home, I am currently in other country, but i will mine with them (or sell them for good price) as soon as I get home  Thanks for tricks... And just a question - is it really possible to overclock them to more then 2,5GH/s? I have read something about max 4 gh/s... Can someone try it and post bad-shares rate? Thanks! I think it's unrealistic without hardware modding to get a stable 2.5+ out of them. |

Hey guys I know it's bitcoin channel and everyone will tell me do not mine BTC with GPU. I know, I got 40gh in BTC in ASIC. Ok, Now I got 2 gpu that are sleeping in my house. I will like to know how I can mine with both if they are 2 different company card. I know how to use Cudaminer and CgMiner but when I start CGminer he choose my nvidia (because she is the main board) and then it crash. How can I tell CGminer to use the second gpu?? Thank  if you have 40gh/s for btc mining, why not just mine scrypt crapcoins and sell them on crypsy for btc? |

My question. Once purchased 1 or more Ghs which is the lifetime of buy 1 month, 1 year?
Lifetime, your gh/s to mine with or trade. i'll give you .1 gh/s to try it. If you hadn't made account I would appreciate the using of my referral link. My Refer Link to cex.ioJust PM me. |

I started mining them, what the hell.

cex.io is cheaper per gh/s than lowend hardware. For a while people were paying $60 for 333Mh/s. Right now for lowend, seems like antminers are the best value if you don't have $500+ to spend.

Why haven't you pasted the print screen in paint, at least and posted the picture? Also, what's the story with AMU10? Dropbox is a habit inherited from other threads that complain about re posting with pictures. I think AMU10 is just about hanging in for the ride. It appears to prefer stock speed. The hubs are 2 x 10 port Orico with 4A psu's cooling is a cheap laptop twin fan cooler. They are running on a Zotac Mini PC along with 70 erupters (there may be another 10 weeks of returns in the erupters) BFG is launched with a .bat file with the comand line "-S amtminer:all" "clock=x0981" The erupters are on another session of BFG "-S erupter:all I think I'll need to wait for my better hub then. I ordered the Anker 3.0 7 port hopefully that provides similar results, otherwise I'll order the Orico. @ chromosoma, cause people on ebay don't understand mining yet.. I use to sell mining contacts at a nice profit too, just a hassle dealing with people sometimes. Least with contacts no one reversed the transaction unlike when I was trying to sell bitcoins. All mining contracts are seriously overpriced, there isn't 0 justification with the excuses of power etc... these sticks are not even a blip in my house power. |

Can you share your setup (hub, cooling, etc), config? It sort of relates to my concern.. you are 2's across the board. |

Seems to me 0981 is the optimal run number, any higher there is issues. Any lower and I'm just doing myself a disservice. They are quite picky about being crowded on cheaper powered hubs. Though right now for me it's an illusion to be running at 2ghs each and I don't understand. Maybe just how I read bfgminer.  I guess I really don't understand the numbers in the middle column. First 2 show about 2ghs then the 3rd shows what I guess is the average. But it's the 3rd one that the pools see. I should be at 10gh/s but it's more like 7.5gh/s in reality. How long have you left them running? It can take hours for it to even out on mine... I managed to find the following explanation of the three columns on google, which helped me understand things a bit better (still getting my head around it all though!); " 5 second exponentially decaying average hash rate / An all time average hash rate / An all time average hash rate based on actual nonces found, adjusted for pool reject and stale rate" My googlefoo sucks bad Thank you! I'm not really complaining too much about the hashrate too much, in my opinion, best value for gh/s to $$ in the < $100 market. Unless people have a few grand to throw at something, these devices are worth it for those wanting to dabble their feet in mining. I've noticed that they killed the block erupter usb (333's) market on ebay. Not certain why the bitfury's @ 2.2 still trying to get $150+ when you can pretty much get 3 of these for that price even at ebay. I guess it's cause the bitfury vendor hasn't realized the competition has raised the bar on price vs gh/s and ease of use. |

Look at it this way. While mining with GPU, let the CPU do some work rather than idle. Save those CPU coins, they might be worth something in the future. Look at Quark......
Yep, I mine primecoins on the side. |

Why wouldn't I just buy .075 worth of Doge on an exchange?

Ohhhhhhh! I just cannot get an antminer working with cgminer on windows 7. I have re-installed the drivers so many times now...rebooted and tried different USB slots and hubs...No luck whatsoever.
Strange, I can get BitMinter to see it and run at 1.6gh (although with at least 10% errors), but can't get cgminer to find it at all, it's although the ant ain't there! :-(
I shall continue to abuse it with the beta java BitMinter client until someone comes up with a something I have yet to try. I'm guessing it's early days yet.
Anyone have anything to suggest that worked for them, let me know please?
This is what I'm running
CP210x_VCP_Windows
zadig install WinUSB (v6.1.7600.16385) (when I do this step, BitMinter can't see it any more, to get BitMinter to work again I install the CP210x driver and voila, there it is....but not on cgminer at any time)
C:\cgminer\new\cgminer-run\cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://mint.bitminter.com:3333 -u xxxxxx.xxxxxx -p xxxxxxx --bmsc-freq 0781
I really want to get it running on cgminer so I can play with cooling and oc-ing it.
Si
Why not just use bfgminer 3.10.0 supports ANTMiner. |

@ philipma1957 - Both you and I ordered on Wednesday, did you see your tracking all the way through on USPS? I haven't received yet, and the last shipping entry shows depart USPS Grand Rapids, and nothing more. Very sad  That would be a USPS problem, I got mine today.. but then I paid for higher shipping option. You have to keep in mind the area is under the effects of weather. |

It's cheesy and I will provide a few pics.. But basically, just set the other PSU on top of your rig and connect the always on loop connection on the 20 pin. Install the card which needs additional power, the green arrow points to the one being powered by the case PSU. The yellow arrow is being powered by the 2nd PSU.  Route your cabling to the additional card from the extra PSU  Just showing the extra PSU on top of the case  Bridge those pins it (I had an extra male adapter with pins so I soldered a bridge)  This is just showing the two wires which get connected.. Basically the bright green with any black.  I'm just doing this till my 850 watt power supply shows up. I'm greedy, had an extra PSU and didn't want to wait to start mining. Doge Address: DKQnN9BDspF7rwLRWR5VzsFn2JfkeTvdEA if it helps and if you're a kind person |
