75°C is not too high, what are you talking about?
Mine been running on 80 for months now.
We are not talking about your card. We are talking about OP's unstable, overclocked card. Please don't crap the thread or assume the task of helping the OP. |

all temp are under 75 so dont think its becuase the heat.
75ēC is too high. Take a look at gpu-z "Sensors" while mining. You will see you're using too much power and/or taking the VRM temperature too high. Voltage oscillates, conditions change and the core locks up. You should undervolt with vbe7 and use a large fan blowing at the cards. Of course it can be the PCI-e riser. Switch cards and see what dies. |

Hey guys. Am trying CGminer for the first time, but with the following in the bat file, it just does not start. Saya--scrypt is an unknown option. This is for a 6990. Any help would be awesome.
cgminer.exe --scrypt -o stratum+tcp://wafflepool.com:3333 -uxxxxxxxx -p x -I 17 -thread-concurrency 8000 -w 256 -lookup-gap 2 -g 1
You must use cgminer 3.7.2, bfgminer or sgminer. GPU (or scrypt ?) mining was removed on recent versions of cgminer. |

huh strange, best hashrate i can get from FX-6300 is 650
Using xpt-bdver1 I'm getting 740 Kh/s out of this same CPU, but at 4Ghz. My rig is fucked CPU mining wise though, memory in single channel Try favorBlend and AVX_favorBlend. You might be able to get a few more khash out of it. I did. xpt-bdver1 gives the highest rate. I don't get it...  740 Kh/s is good though, considering single-channel ram and how it compares with the i7-4770 above |

Does it fail to recognize a card in that slot in the first place, or only does so with all cards plugged? Some motherboards disable one PCI-e slot if the adjacent is populated. Or it can be that you forgot to disable sound, firewire or whatever else the MB has that isn't required for mining in the BIOS and is using PCI-e lanes. Ubuntu isn't usually a very stable or mature Linux distro. May or may not have influence, not sure. As a side note, I've read that 14.1 drivers give lower hashrate. Edit: Read the 2nd post here: https://bitcointalk.org/index.php?topic=296581.0 |

Gigabyte R9 270: VOLTAGE LOCKED!  Tried 1.100v and 1.150v in VBE7, flashed BIOS, no errors, but the cards hang on boot when X starts. Running stock, these cards draw 30w more per card than the Asus 270's, for a just a slight 10 kh improvement. Gigabyte R9 270: Modable with VBE7 I'm running 2 at 1.043V and hashing at 475 Kh/s and 445 Kh/s on W7 and Catalyst 13.12 without any issues. Hanging on boot on your rig or OS installation is no evidence whatsoever that they are voltage locked. Perhaps you forgot to set also a lower clock speed on VBE7 |

what have changed?! please help me thank you so much!
by the way i upgraded to 14.1 Mantle Driver

I also read this: 1 billion NXT were initially distributed between just 70 people, that wasn't even a month ago. These 70 people ALL TOGETHER paid 21 btc for it. If you look at the market price now, these 1 billion NXT would be valued at more than 70000 BTC. Does that make any sense? You're right, it doesn't.
Forget about this scam coin. It's nice if someone creates a new and bitcoin-independant code base, but getting the initial distribution of the currency so fundamentally wrong is just unacceptable. There is a REASON satoshi didn't just split 21 million bitcoin between himself and four or five friends of his.... I wonder if I could also "develop" a scamcoin, think about some innovative promotion, and get rich out of thin air like this... |

this is a coin that should be held in high regard in the Alt section as a serious contender to topple Bitcoin, instead most hate it out of ignorance or misinformation. You want it to topple Bitcoin because...? People can go back to their junk coins for all I care.. Nxt isn't also a shitcoin because ...? This one isn't even rhetorical, I have no clue what makes Nxt special. |

That's a good estimation if scrypt alts are worth in April what they are now. Otherwise, people will dump their hardware and you can get screwed.
I would not hesitate myself to give you 1500 (~$2000) in hand for your (I assume) 4 Mh/s rig, assembled, tested and working.
I'm sure you would considering the going rate is $1/kh for a working rig. It's the going rate... for idiots. A new R9-270 gives 475 Kh/s for 170. That is actually a good point, though. Only God knows how much you manage to get out of it if you sell it to someone without much clue. $3k is actually possible.  |

If all conditions(including there being no Scrypt ASIC) are around the same as now,I'd agree. Including with Scrypt ASICs, because I see no evidence of them offering more Kh / $ |

Can someone explain how do I generate a coin deposit address.
Just opened a acount on cryptsy, do I need to copy paste my own coin address where it says, Deposit BitCoin & AutoSell Setup, Deposits post after 4 confirmations. You may use older addresses after generating a new address?
I don't know what this means, at coinedup a coin address is generated?
you click the button that says "generate new address" i find it utterly amazing that people can use computers without reading. The average IQ on this forum is somewhere around 80. The elitism on this forum is over 9000. |

Good luck with your pool  Offtopic: the problem of using SSDs is people's stupidity. They believe just because these are "OMG SSDs pwn HDDs", they can get away with consumer grade crap or without RAID1/5 |

It is possible and it's also possible pool operators steal coins, but variability is expected. Depends on pool luck. Most pools offer many graphs and the transaction details
Even more when everyone is mining Dogecoin, which gives a variable amount of coins per mined block.
