Able to overclock my windforce 7970 to 1080/1500 with -20 power, although the temperature is still around 90 degrees!
Is this normal? The card gets fresh air but originally sat at around 70 but now is always above 88 under load. Changing the power setting seems to do nothing.
Yes, if you overclock your gpus they get hotter. What I meant is it used to run at 70-73 overclocked at that speed, one day it was suddenly almost 20 degrees hotter. Could this be a sign of the the VRM going dodgy? Only a month old! |

It's the Retail version. Which means it's in a colourful box for bragging purposes with a handbook and a driver CD and (for other hardware some cabling) and there may be some coupons for games in there too.
The alternative is Bulk. Which means you get the video card in an antistatic bag. There may or may not be a flimsy plain box around it the bag. That's it. No extras. No CDs. No handbooks. No coupons.
This, the OEM/bulk is for people who want a card in a computer - system builders normally. The "retail' edition is for the shops/end consumer. |

do you work together with someone selling chips to ?
I agree someone needs to do UK finished boards! Seems so odd buying components and sending them off to be affixed to boards - you could make more of a markup and have wayyyyy more customers if you just got some chips! Less responsibility with collecting them in the post, keeping track of who's is who's etc. |

Just a question BKKcoins... will each board have a serial / id number?
Maybe a sticker with a serial number in a keepout zone? I noticed that some manufactures offer the service of embedding an RFID chip in the board material itself. I wonder what the cost is, but I'd bet it would double the cost of this board. I think he means in the firmware so mining software can differentiate. Couldn't the share LED's be used for troubleshooting? A raspi could be setup to monitor how often they blink with the new camera attatchment. |

i already called it.... once they were willing to let a community member from the forums visit their site it screamed DOG AND PONY SHOW.Sure enough that is what it was. All visits have really produced nothing at the customer end nor did it prove that BFL actually have what they say they have, beside all the stupid cases for mini rigs that they dont need anymore. Sorry PG I just had to get credit lol you know me.  They do need those cases. Where else would they have put all the trade in FPGAs? |

So you've bought so much the they need a 9x5x5 foot box to ship it to you, and still only $200, bargain!? |

I don't think each board will but possibly each PIC chip may, stored in it's flash memory. Just a question BKKcoins... will each board have a serial / id number?
+1 for USb serial so we can distinguish multiple boards in cgminer  I think probably each USB chain will appear as one unit. Not sure yet as I haven't got into the cgminer code, but if you have a dozen or two boards you don't really want a display with 12-24 lines of 300MHz each - or do you? I wouldn't. And what about people with 60 boards on one chain... Those are smaller than you indicate by 10x. 13mm not 130mm. They may be good as one per chip but they wouldn't work for the whole board (obviously). There's a lot of these RAM/VGA chip coolers out there. They may work per chip but once you add them up you end up spending more than one big heat sink. (I'm looking for a nice blue cool looking one for the K1 however, about 1"x1.25"). "Effy Deal Global" - with a name like that I hope they're not real. But who knows. The price doesn't surprise me at all. I'm expecting to pay $2.70 each in qty 100. Unit error doh. I only just woke up sorry. You say it might cost but tis a pack of 8 and if you buy three pack the price drops to $1.88! blue ones, a bit dearer tho! although they are a bit bigger 15x15mmAlso, for the k16s; are there many raised components on the back of the board? IE will we be able to use a flat heatsink that is bigger than the total board footprint, got an old TEC waterblock I'd love to use! |

Remove any *.bin files and run again. I see this when I switch between litecoin and bitcoin mining and don't delete the *.bin files first. cgminer will recreate them when it starts up.
There are none, this happens with a fresh unzipped download too. |

it is best if you post your config....
Ah good point  |

Hi there, been mining for a while on a 7970 at 725kHash on litecoin. Im trying to now mine bitcoin, yet my speed is also listed in kHash (around 750) but no work gets done or shares accepted.
Also the card sits about 30 degrees cooler than with litecoin so the card obviously isn't under proper load. I've tried redownloading cgminer to no avail. Help!?
And yes I have removed --scrypt

I would be interested in purchasing said item only if it retains the above-seen color scheme. Seriously tho - nice work! Not sure if you can get teal PCB lol. About the thermal vias, does that mean the heatsinking is going to be on the opposite side of the board? That's odd, compared to any other chip I've had to cool anyway. As for what heatsink to get a northbridge style one could possible work quite well for this. |

I think they are paying to the old investment with the next ones, and it will just crash once its not sustainable anymore. Where are they renting from? So for all places I have seen that rent computing power you have to play 10-50 times more then you what you earn in bitcoins.
It says this on their site: NOTICE: BitCoin addresses associated with the mining servers are not public. BitCoins from our public addresses (the addresses Bitcoin are sent to buy mining packages) are used for payouts first until depleted, and then the secondary addresses are used. This is to protect the master wallet address from potential threats. Which does make sense but it could also be there to cover their arses if ever accused of being a ponzi scheme. |

that the problem of cpu coins.... I do have an idea for a new coin, but it'll take a lot of coding, and atm I dont have the time....dont think it'd be cpu friendly though, but def asic unfriendly  Someone need to make one you solve with a pen n paper. |

It's too late. Cats out of the bag. Alt coins will never stop.
But they will also never be as profitable as FTC was in the first few days. |

Well I don't know, I have mined a bit there just to see if I'll get payout, since everyone here says it's a scam pool, but I got the payout so I stayed there and I'm getting paid without problem...
You seem to be totally trustable person, not. IIRC he did have issues with payouts due to some hacking at one point with FTC but got paid in the end. |

Meh up!
You'll get half a bitcoin at exchanges for the ones actually 'worth' anything; yac/ltc/ftc. Why on earth would anyone want to? |
