Good price, if I had a power supply that could take two of them I'd buy them. These are crazy LTC mining cards, they get ~900 kh/s each. They'll probably be gone by the end of today.

As in title,
Want a 6950 shipped to my address in Canada for $150 USD/CAD PP, LTC, or BTC.
Must accept escrow from a trusted forum member.
edit: fulfilled

Updating to 12.10 is netting me an extra 25kh/s for 3x 7950s... a small improvement I guess. I'm running a 5830 using cgminer at 900/1200. My config file is cgminer --scrypt -o http://yourpool.com -u username -p password --thread-concurrency 5600 -I 20 -g 1 -w 256 I'm getting 288k/h. Fan is set at 60% and I range in temp from 77-80C depending on ambient. Any thoughts or suggestions or should I leave well enough alone? Just try to get the memory as high as it will go... otherwise that's about as much as you'll get from that card. |

Also thanks to whoever sent me 10 LTC <3
Has anyone tried the 12.10 / 12.11b drivers yet? Do they confer any additional kh/s? Someone in another thread said they got a huge boost but it made their computer unstable

Sorry with all the trolling I've been doing I haven't had enough time to remember this... I know it was discussed a while back, but PPC uses a modified hashing algorithm from bitcoin? I can't remember what it was. Thanks for the info!  It's SHA256, but, unlike LTC it modifys the important stuff.  |

 do not worry, production is going normally, singles should be out in three days. |

That sounds similar to my cards... I'll note that TDP is usually a function of the square of the voltage, so the increase in power consumption with hash rate is unlikely to be linear. For me, it takes an extra 28% of power to achieve an extra 20% in hash rate. edit: I just got an extra 150 kh/s as well by disabling my cpu by adding the following to reaper.conf platform 0
device 0
device 1
device 2 for 3x 7950s |

LTC mining requires 128kb of memory per circuit. Both bandwidth and size are important. Additionally, sometimes larger sizes are required for unknown reasons (especially for the 7xxx series).
For the 7970, cgminer currently gives about the same hash rate as reaper. Theoretically the 7970 should get ~700kh/s, but no one seems to be able to achieve that with either program yet.

okay, i am going to give this a try guys. i'll let you know how it goes.

I have this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125439I've always preferred reference coolers, as the main heatsink directly cools the VRMs, but I went with this one. I ended up putting little aluminum RAM heatsinks on the back of the VRMs, cuz they were getting too hot. That's the only issue I've had, and once I got past that, it's the best card I've ever owned! I can overclock it to 1200MHz, even with my low ASIC quality. I normally run it at 1050MHz @ 1050mV, tho. You can't hear the fan < 50%. I normally run it at 60-70%, and it keeps my core between 55-60C, and my VRMs around 65-76C, depending on ambient. I would note that most MOSFETs are rated to 125-175C... I haven't had any problems with stability with mine running between 90-100C You just have to make sure the surrounding components don't get too hot, but if you have the fan on 100% it should be okay |

MSI or Gigabyte
NOT XFX, their cards have the shittest cooling solutions

And how about a higher thread concurrency, is it possible now to use larger values (ex 24576)?
? They're fine to use in reaper, I think I'm using 24000. |

As I stated in the op, you have to bypass the ocl error check to use a large amount of memory as with the 7950. Coblee has stated he will not remove cgminers error checking.
Coblee? Anyway, from the latest cgminer changelog (2.8.4) : Scrypt will now not fail when setting high thread concurrency values that still return some ram even if opencl returns an error on that ram allocation. Maybe you could try again with cgminer ? ckolivas i meant, sorry. i played with my 7950s tonight. the lowest power consumption i could get was the following (1550kh/s for 3x 7950s): Mem: 1550MHz Core: 900MHz vCore: 938v Power at the wall per card: 177W Efficiency: 2.92 KH/S/W AC current The power consumption also goes down with temperature, and you can watch it go up when you just start mining due to heat. |

I am looking for a takoyaki pan (electric or non-electric), a takoyaki oil brush, a makiyakinabe, a panda face onigiri maker, different kinds of bulk sencha, gyokuro, and tamaryokucha leaf tea, Doki Doki Nyan Egg NEKO TAMAGO keychains, and instant miso soup mixes.
Let me know if you can get these things, what prices you charge, and how much it is to ship. I am looking to order ASAP as most of this is Christmas gifts. Also cute Japanese Christmas cards with Japanese art in the I would also be interested in.

7970: 21000 (sharethreads 2048 and threads_per_gpu 4, the rest the same as the above and using catalyst 12.6 and AMD APP SDK 2.6) (~700 kh/s)
Is that sharethreads 2048 correct??? That is a LOT of threads! When I put that in, it would just crash my PC, or very unresponsive. i changed that because it doesn't really work. that's for 79xx cards only though. we're still looking for the right settings for 7970s. |

Do you remember when I called you out on saying "personally", or did you forget that already. I'm actually starting to enjoy these bitcoin forums, at first I was mad about all the scams/liars here but now I just hope I can use my new found lie detecting skills in more real life situations
