if you're gonna roll the prices back why not just and put all your money back in a fake government backed money bank. if you're too fucking stupid to set a long enough password to prevent it being stolen you deserve to have it all stolen. Regulating the market is NOT in the spirit of bitcoin.
I agree. (because I had 100s of fulfilled orders @ 0.1 BTC)  |

it didn't crash, nor it glitch out. Simply someone cashed in their own or stolen BTC in a public market.

Well, should we start to panick ?
that's never a good solution MTGOX HAXED?
i mean, who will sell that much bitcoins?
more likely an early adopter got his wallet taken over. |

It would be very unwise for miners to sell right now. Just putting it out there if anyone is worried and considering dumping. This fluctuation should resolve itself within a day or so. Buying right now is actually a better decision (anywhere below 16 isn't too bad, but 12 would be sweet).
All IMO
That's exactly what a person about to cash in would say  |

$14 and dropping fast  What do you reckon, buy @ $10 ? $13 !! price is dropping every click of the mouse button ... go go go Hmm, I'm thinking buy @ $5 - $7 My humble prediction is that it'll plummet to sub $10 in the very near future. Once below 10, the floodgates will open and a lot of panicking people will want to cash in, driving the value even lower (exactly what we're seeing now, just on a grander scale). Wether there's gonna be a dead cat bounce or not, hard to tell. |

This all makes me think about returning all the hardware back to store - here in Russia we have 2 weeks grace period where we can return stuff to the store even if there is no issues with it..
That's a good idea. Although I am not from Russia, I will do the same if the value drops bellow $10-12 (loaned hardware FTW). |

i have 3 6950s unlokced and i run them at 1.2v and i can get to 930 core and if i go to 1.25 i can get to 960 to pull about 410mhs per card. and 900 is still a lot for stock vcore the 6970 runs at 880 stock core at 1.17v so up you v to at least 1.175- 1.2 range (if you temps are lower then 80c) and then try for 900
Yeah. ATM I'm running them both 1175mV 925/625 for ~800mh/s total. With a fanspeed of 70% and an open window, they run at 60'C and 64'C. Sad thing is, I cannot find that golden ratio between heat and speed when the fan speed is a tad bit lower (60-65%) - either it has to run the same 1175mV voltage and use quite lower clocks (~900mhz) with higher temperature (79'C+), or use near-stock overclock (~845) with stock voltage, which would let me use it bellow 60% fan speed anyway. All I'm trying to figure out, why there's such a gap in fan speed performance, and why it crashes so weirdly when approaching it. |

Other / CPU/GPU Bitcoin mining hardware / 6950 + system hanging

Hello guys.
I am mining with 2x unlocked XFX 6950's. Lately I've been trying to find an overclock that's stable with 63% fan speed (night-mode), but all of them are pretty much unusable, and the way it crashes the system is very weird - on a "bad" overclock firstly the cards heat up to working temperature (between 65-80 depending on mV and mhz) and then stay there for a while (from 1 to 60 minutes); then, suddenly temperature drops on a single card, and the hashrate halves. If I move my mouse, the computer hangs. If not - the second GPU continues to mine for a little longer (2-3min) before a total freeze.
What surprised me the most, however, was results I got from last night: I let both of them run @ 1100mV(stock voltage) and with 900mhz core/625mhz mem and went to bed after 20-30mins of it being stable. It ran smoothly for an hour or so (according to BTCGuild logs) and crashed an hour later. I surely thought running it on stock voltage and such a low overclock (stock max is 840mhz core) will help the stability. I am sure it crashed the same way (single gpu halting for no reason, and then, even with 99% usage dropping temperature until a full system crash).
What could be the reason for such weird behaviour? What kind of overclocks do you have on your 6950s?
