Selling your MMC at a discounted rate due to the lower rate of electricity required to generate it will eventually find a way to cut off CPU mining.
This is just my opinion for the matter.
It's a tough one to call - there are so many factors involved. What I see happening is that more and more GPUs and CPUs will start mining until profits are driven down . . . causing the GPUs to mine something else, leaving only the CPUs because they have nowhere more profitable to go. If GPU mining is more power efficient, then CPU mining will be driven out of MMC mining, not other way around. Is it possible to change the memory requirement (say 4GB instead of 1GB at present) so that it is still a CPU coin? |

Is auto pay out still working? Do I have to use cash tool?

781 BTC payments successfully sent. Please note we certainly have a back log of the email support queue. We are working through it the best we can while still trying to get things done with the backend/site ect.
What are the criteria to send out those (781 transactions) BTC? Is it because they are over the preset withdraw limit? |

There is an optimised Optimized scrypt kernel files for 7950/7970/7990/R9 280x https://litecointalk.org/index.php?topic=6058.0;topicseenIt can increase the speed. If combine your script with that one, can we increase the speed further? From your instruction, we have to delete the existing .bin files. |

Thank you for confirming that running 8x HD79XX gpus under windows is possible.
As far as I see, most people are limited by 6 or 7 gpus. Is there any tricks to do that?
There is no trick I think. Or W8 did the trick. I have not tried 4X7990 on W7, so I cannot say W7 does not support 8 GPUs. I have 5 different types of MB, all can run 4X7990. One of them is Asus P55 chipset, no problem running 4X7990. If you cannot see all 8 GPUs, just reinstall Catalyst. In my PCs, catalyst earlier than 13.4 does recognise 7990. |

I have personally verified that you can not install more than 6 GPUs with windows 7.
The only thing you've personally verified is the fact that you were unable to install more than 6 GPUs with windows 7. Windows XP 32 bit + 8 GPUs - http://foldingforum.org/viewtopic.php?f=38&t=7902&start=270#p115136Yeah.. that's two core nvidia cards, but they do count as GPUs, right ; ) I think that there is no hard coded limit or any limitation of GPUs in both Linux and Windows. However when installing 8+ GPUs there are certain issues with BIOS unable to map all the GPUs. Can't remember the project name right now, but guys made 10(not sure about the number but above 8 ) nvidia GPU rig, they had to use custom BIOS and custom linux kernel pathes to make it work. Plus there is known issue with Windows ATI driver, which prevents you from n+ GPUs drivers being properly installed. Some people claim n=4, some n=5. For my setup(GA-990FXA-UD3 + 2x6950 + 2x7950) n=5. And in order to use 6GPUs in Windows I needed either to use 12.6 driver downloaded from AMD or 13.1 driver downloaded from techpowerup. Also that 13.1 from techpowerup driver is different from 13.1 from AMD driver only in registry, so I assume that with some mod it is possible to use any driver version for 6GPU rigs. So unless s1 explains why it is not possible technically to use 6+ AMD GPUs in Windows I consider it is doable. "Windows sux"/"I was not able to use more than n GPUs in Windows"/"AMD drivers are crap" are not technical explanations. So it sounds like you are saying windows XP can do 8 GPUs. Had I known that I would have tried XP and skipped windows 7. But XP wanted dummy plugs on the DVI ports of unused cards. That was why I went with windows 7. Also finding PSUs to support 7 GPUs rather than 6 ended up needing 3 PSUs rather than 2 (When you go the economy path) I am impressed someone else got 8 to work. Linux? I read that windows 7 (not XP) is limited to 6 because they never imagined anyone would want more then 6 GPUs. I have 8 GPUs working on several rigs on Windows 8. 3X7990 + 2X7970 = 8 GPUs, mother board, ASUS Rampage4 extreme, This MB has 6 PCIE slots. Catalyst 13.4. 4X7990 = 8 GPUs. MB: Gigabyte XKT-1155 Z68AP-D3. This MB has 5 PCIE slots. Catalyst: 13.6 or 13.9. I wonder if anybody can make 5X7990 work on W8. |

How do I use 2 PCs to mine so that I will not mine the same part of the hash? Do I need to use same wallet.dat?

I have 17X7990 in total. The core/memory voltage and frequency vary because every GPU is different. For some GPU, I can run 0.99v, with 950/1000 MHz, temperature is 70C. For others, the temperature is 85C, with 0.95V, 870/900 MHz. It depends on the position of the cards in a PC case.
I use powered PCIE risers in open case, I put extra fans to extract heat out.
The original thermal past is extremely thick. I tried to apply thin layer of thermal paste, the improvement is minimal, just 2-5 degree, as the heat sink cannot touch the GPU evenly, even after I adjusted the force with the 4 screws. That could be the reason why manufacturer apply a thick layer of thermal paste.

I just built a 7x5970 miner and installed Windows 8.1 to break the Win7 limitation of only 4 of the same card. But, I cannot get cgminer 3.7.2 to run with even one card plugged in. I've tried Catalyst 12.8, 13.1 and 13.9. When I launch cgminer it lists the pools and then maybe compiles the scrypt executable, or not, but just hangs, often freezing Win8.1 requiring a reboot. I've searched around and the references I've found imply how easy it is. Does anybody know what I should try or have a link to a good Windows 8.1 mining setup page  TIA 7X5970 means 14 GPU core. I heard that Windows 8 only supports 8 GPU. Does W8.1 support 14 GPU? Can you run with 3.2.1? Oh yeah, GPUs not cards. I think the limitation is defined by GPUs. But, I still could not get even one 5970 by itself to run. I have 3x7970s plus 4x7870s installed now and Windows 8.1 is only recognizing 3 Pitcairns and 2 Tahitis. No idea why. What's 3.2.1 CGminer 3.2.1. I use that to run 4X7990, which has 8 GPU in total. |

5177 to 5183 all red and no blocks
There is no need to worry. This is just a databse issue. Look a few posts back. |

What I want to change is to express the "my estimated earning" in each round in mBTC as there are too many zeros before a nonzero number in a small earning in each round. The client ledger and coin balance can still be in BTC. Our brain should be powerful enough to convert between mBTC and BTC, but it takes me some time to count zeros.
There is an easy fix for that. Get more hashpower. I have 27MH/s here, but in each round, I still get 0.00X BTC. 5158 WDC 4 224.75 17 959.44 23.75 200.99 0.02036 BTC 5157 ANC 0 0 20 101.01 0 0 0.017933 BTC 5156 FST 66 2112.1 3 97.8 82.16 2029.94 0.00293 BTC 5155 SBC 125 3127.15 0 0 354.37 2772.78 0.021681 BTC 5154 WDC 49 2756.72 0 0 321.4 2435.33 0.04018 BTC 5153 ANC 8 40.2 0 0 5.72 34.48 0.003506 BTC 5152 CGB 29 18.13 0 0 2.37 15.76 0.00079 BTC 5151 ANC 5 25.1 0 0 3.75 21.35 0.002257 BTC 5150 WDC 4 224.85 0 0 28.98 195.86 0.002265 BTC 5149 ANC 10 50.11 0 0 7.32 42.79 0.003661 BTC 5148 WDC 4 224.65 0 0 27.38 197.26 0.00166 BTC Where are you pulling these numbers from that you are able to get more precise numbers? Below your post but above this post i posted the chart as well and came straight from website as a copy and paste and my numbers are not precise like this. So where can i get these numbers like you did? They are from the same place. My hash power (27MH/s) is much higher than yours, so there are more nonzero digits. |

how is this most profitable?
5155 SBC 03:01:59 AM 125 3127.15 0 0 354.37 2772.78 0.000002 BTC
5154 WDC 02:39:58 AM 49 2756.72 0 0 321.4 2435. 0.000017 BTC
im referring to SBC at a little over 3 hours for only 0.000002 and its green so its complete
compared to WDC at close to 3 hours and makes 8 times more in less time at 0.000017
even FST at 36 minutes has more profit in way less time
5161 FST 00:35:58 177 5666.3 61 1952.2 0 0 0.000004 BTC
while FST not green yet i dont expect it to change so drastic it would be worse then SBC.
so again how is SBC more profitable?
That was when the pool was down. |

no sense to buy a 7990
280x = 750 kh/s - 275w
7990 = 1300 kh/s - 500w
7990 = about 70% faster - about 80% consumption = fail
For me 7970 = 750 kh/s - 260w = 2.88 kH/s/W core/memory: 1.113/1.5V, 1065/1500MHz 7990 = 1300 kh/s - 400w = 3.25 kH/s/W core/memory: 1.0V, 950/1000MHz So 7990 is better. We can use 4x7990 but only 7x7970 on a MB. If we can undervolt the memory, it is even better. The temperature I get is from 65C to 92C depending on the position of the card and quality of the GPU and how the thermal paste was applied. Some times I have to undervolt to 0.96V so that it runs at 860/900MHz to keep temperature below 85C. I am thinking of reapplying the thermal paste, but not sure if it will void the warranty. |
