Bitcoin / Mining support / Help me with a simple Linux script
|
on: August 02, 2011, 07:53:30 PM
|
Here's what I'm trying to do, I am trying to extract the temperature from every card and send them to my web server as a GET request so I can update a database on my web server. What I have so far: export DISPLAY=:0;aticonfig --adapter=all --odgt | grep -o '...\...' | sed -e 's/^[ \t]*//' This gives me: 91.00
91.50
91.00
82.50 How do I chop this with shell scripting and send it as part of a GET request as such: GET http://www.mywebsite.com/update_temp.php?rig=1&temp1=91.00&temp2=91.50&temp3=91.00&temp4=82.50 Thanks Gurus! |

Bitcoin / Project Development / Re: BAMT - Easy persistent USB key based linux for dedicated miners/mining farms
|
on: July 30, 2011, 06:29:08 PM

I tried burning the image to my usb drives (several kinds) which were confirmed to be working with Ubuntu. I used the win32diskimager tool as suggested on the BAMT site.
I am unable to boot from any of them at all though the files show I fine when I check them in Windows.
Any idea what might be going wrong?
If win32diskimager completed the write without errors, you're probably doing everything right. Some motherboards, especially gigabyte, just have trouble booting from USB. You may be able to get it working by updating bios to a newer version, that has worked for some people. Or, it may just not work with your system. Since I haven't found any systems here that don't work, I'm not able to do much to troubleshoot why some mbs don't work. Its really strange because when I used the same thumbdrive and motherboards, both Ubuntu & Debian images are booting fine for me. There is a 4.0b out so I will give that a try after I download it. |

Bitcoin / Mining support / Linux + Phoenix = 1 GPU stuck in "medium / level 2" profile
|
on: July 25, 2011, 03:54:37 AM
|
|
Whenever I use aticonfig to set clocks (aticonfig allows me to set clocks beyond BIOS limits), one of my cards is always stuck in a lower power state profile for some reason.
For example, if I have a bunch of 5970s, I can set all the GPU clocks to 800,300. I fire up an instance of phoenix on each GPU and it will report 350~360 mhash per GPU except for 1 GPU which will be hovering between 240 and 360 because its clocks keep dropping down to 500mhz. I know this isn't a temperature issue because all the cards are at the same temps.
The most obvious sign that this is a profile problem is probably the fact that this can be rectified by setting all the profiles to the same clock values in AMDOverdriveCtrl. But for reasons discussed in the first paragraph I prefer to use aticonfig. Does anyone have any idea what I can do?
Many thanks in advance.

Bitcoin / Bitcoin Technical Support / Re: 6 GPUs 5850 on one mainboard
|

My PSU does 1200W what should be more than enough:
6*170W = 1020W + 30W (CPU) = 1050W makes 150W for fans, mainbaord and backup.
Downclocking my GPUs to 500/300 before mining, to reduce power consumtion, doesn't work neither.
Any ideas? Why does the one pcie 1x port work, but not the other one?
Your forgetting that your 1200W PSU if its 80 Plus certified is only good for 80% of 1200 watts. Bronze, silver, and other ratings give a little more. Say you have a gold certified at 86% thats only 1032 Watts I ran 2 5850's and 1 5870 and had a PSU fail to work at 850 watts, needed 1000 watt PSU. You just dont have enough in your PSU in my opinion. You got it backwards. 1200W means it can deliver 1200W to your components, and will draw even more from the wall because of inefficiency. In addition, most branded PSUs will happily deliver 100W-200W more than what they are rated for as well before over current protection kicks in. What you lose is some efficiency (80+ Gold PSUs for example may drop to like 80% efficiency when overloaded). |

Other / Beginners & Help / Re: Barrier to widespread use of bitcoin
|

Talking with friends and neighbors, it seems a huge barrier is the technical nature of Bitcoin e.g. understanding it in general & how only computer-savvy users can set up a mining rig. But better and better videos are coming out explaining Bitcoin - and I guess they could always buy a pre-built mining rig  I'd be happy to set one up for them too  Gold wouldn't have worked well if almost everybody interested in using gold was able to mine it though! I think mining should be a small part of bitcoin, at least much smaller than it is at the moment. |

Economy / Services / Re: [100 Ghps] "Catch 22 removal" service for new pool operators
|

Seriously, if I were to start a pool I would find anything below 250 or so giga bad to start - and vladimir may be able to add 50gb for the mere price of 5gb of my capacity. I will never understand why people mine in a pool that does not solve a block on avereage every 6 hours. The variance will jsut totally kill you. Whoever mines in one of those micro pools - wants thrill, not money.
You should have been around before pools, when everyone was solo mining and we all found blocks every few days. And pizzas cost 10,000 BTC. If you found only a block every few days, it would take 2 years to accumulate 10,000 BTC for that pizzaa  |

Bitcoin / Mining support / Re: Driver crash? 1BTC Reward offered for solution

This might not be causing the problem but what power supply are you using? I looked up the watt usage for a 6950 and its 312 at full stress which x5 is 1,560 watts and that doesn't include the mobo hd ect.
Silverstone Strider Gold 1200W. I have plenty of headroom. Also, the miners crash when I try to start them when there is 0 load. I'm kinda confused how do you plan to run 5 6950's off a 1200 w power supply if when they are mining each card runs at 312 watts? I may have that number wrong but I looked it up here: http://www.guru3d.com/article/radeon-6950-6970-review/11Does it crash the moment you start mining with one card or when your mining with 4 cards and you begin mining the 5th? You do have that number wrong. 312 watts would be for that entire system. I believe a 6950 requires 2x 6 pin slots. Each 6 pins pulls 75 watts max. The motherboard may also pull another 15 watts per card. That's 165 watts PER card times 5 cards. 825 watts, say a 125 watt CPU and another 100 watts for other stuff (multiple hdds/whatever), still under 1200 limits. The problem does seem to be windows, have you tried in linux? I think LinuxCoin would be helpful in this situation (live, already ready for a test). ~bluefirecorp This is not entirely correct either. Each 6 pin can deliver much more than 75 watts (although 75 watts is the recommended maximum) and often does under high overclocks. But you are in saying that 5 cards would be easily handled by the PSU. I agree that you should test it with Linux (just run LinuxCoin) to be sure that its a software issue. |

Bitcoin / Pools / Re: Pool hopping shouldn't be relevant.

Wrong.
Suppose pools A & B solve on average 1 block / hour. And Miner X is responsible for exactly 1% of the pool's hashing power (0.5 BTC reward for staying the entire round duration).
Miner X starts in pool A.
Precondition 1) A has not found any block for 6 hours.
Precondition 2) B just found a block a minute ago.
He has 2 options.
Option 1) Stay in A.
Option 2) Go to B.
Chances of both A and B finding a block in the next hour is exactly the same.
Expected returns (on average) after another 1 hour of mining for:
Option 1) 0.5 BTC
Option 2) 0.5 BTC (from B) + 6/7 * 0.5 BTC (from A)
