What pool do you mine on? If your pool switches coins, that easily locks up cards. The fix? Install CGWatcher and have it restart mining when cards go sick or cgminer freezes etc. If you mine on a multicoin pool try mining only litecoin (for example) for 24 hours and see if you get a crash....if not then just use the fix I listed above. here is my btc address if my solution works for you  1KnyGG1sySxmCGAD2AAukCWPT8T1o22rhK |

With my very limited GPU mining experience I've found that mining cards with just 1 fan over the GPU simply isnt enough and leads to overheating issues far too frequently. I even have 2 120mm fans over one of my 1 fan video cards and it simply is not the same as having 2 fans built into the graphics card.

I've never had any issues with coinbase at all and I use them daily most purchases/sells that I've been conducting are around 0.1-1 BTC each

Where did you purchase the parts for the metal frame? I've check home depot and they seem to only have "heavy duty" angled metal and it's pretty expensive as well. |

Okay looks like my biggest problem was using cgminer 3.7.2 instead of 3.1.1 . My second biggest problem is that for some reason my video card cant go over 1000 gpu core without getting hardware errors. I'm now running at 570 kh/s (which is a nice improvement over my 430-460), but it would have been really nice to break 600 kh/s.
Wolf0 you will definitely get $5 in btc and if no one can get me over 600 kh/s then you will get the full $10 (or if you can get me over 600 you can get the full $10). Can anyone help me get over 600 kh/s on my 7950? currently im using this my 7950 is my gpu 1

okay switching to cgminer 3.1.1 and using the settings you suggested
|
|
|
|
Use 1500 memclock, 1100 core. 1 GPU thread, 19 intensity. Thread concurrency 24064.
It submitted 1024 shares, it then got 4 hardware errors and crashed. Try CGMiner 3.1.1. I agree. I'm still on CGMiner 2.11.4. I should upgrade but I don't want to mess with it. Are you serious? You know there have been speed improvements to the scrypt code since then, right? I'm using cgminer 3.7.2 |
|
|
|
|
Using your config It keeps starting off well hashing at 650 kh/s, is able to submit about 384 shares and then it just stops working. CGMiner then declares it sick. I'm going to try to lower the memory clock a bit and see if that makes it more stable. Intensity i'm using is 19.

Here's my settings. I have 3x MSI 7950. I get 650-670 KH/s, max temp 69, 250W from the wall, from each. It runs 24x7 and only stops when I stop it. GPU 2/3 were running much slower than GPU 0 until I lowered GPU 0 intensity to 19. Then all 3 GPUs leveled out at 650-670 KH/s (average, not max/min).

Try it out. I'd say set it to intensity 20 since it's not GPU 0
Ok I'll try this out right now |

If you are getting crazy amounts of HW errors you have to lower your intensity.
I'm going to try lowering the intensity to 17 and will update |
|
|
|
Use 1500 memclock, 1100 core. 1 GPU thread, 19 intensity. Thread concurrency 24064.
It submitted 1024 shares, it then got 4 hardware errors and crashed. |

Ok I'm in the process of trying all the suggestions right now. Unfortunately when I get a bunch of hardware errors cgminer doesnt close properly and I can't even kill the PID so I have to reboot inbetween attempts. So bare with me The person who gives me the tip that solves my problem will get $10-15 in btc/ltc/doge or if I have to combine multiple tips to get it to work I will split it up by who contributed most to get it working. I also just appreciate the advice that you guys are willing to give me ) |

Ok with your settings my hash rate does jump up to 630 kh/s but then my WU goes to 0 due to all hardware errors. Any advice?
|
|
|
|
|
How do I set the voltage on linux? I'll try the other settings right now.

So I have a MSI 7950 and it's only getting 510 kh/s and WU is only 450/m. Here are the settings that I'm running with Cgminer. My 7950 is gpu 1 so it's settings are in the middle of my 7870 cards which are gpu 0 and gpu 2. I bolded my 7950 settings "intensity" : "19, 19,19", "thread-concurrency" : "16384, 24768,16384", "worksize" : "256", "gpu-engine" : "1000, 1000,1000", "gpu-fan" : "0-85, 0-85,0-85", "gpu-memclock" : "1200, 1200,1200", "gpu-powertune" : "20, 20,20", "shaders" : "0", "temp-cutoff" : "95, 95,95", "temp-overheat" : "88, 88,88", "temp-target" : "75, 75,75", "lookup-gap" : "0", "vectors" : "1", "auto-fan" : true, "expiry" : "120", "failover-only" : true, "gpu-threads" : "1", "log" : "5", "queue" : "1", "scan-time" : "60", "temp-hysteresis" : "3", "kernel" : "scrypt", "scrypt" : true, "gpu-platform" : "0", "shares" : "0", "kernel-path" : "/usr/local/bin" If anyone can help me fix this I will tip you some bitcoin, litecoin or dogecoin |

You should have combined your 7 threads into 1: "Selling many Star Trek Online goods". Otherwise you appear to be very spamish...

As a scientist, I find that the one thing the mainstream media distorts even more than Bitcoin is science.
This is a perfect example of PR people and clueless journalists blowing things waaaay out of proportion. This is an important discovery, but to call it a "second genetic code" is absurd. All they've discovered is that transcription factors sometimes bind exons. It's interesting, sure, but whether or not it has any far-reaching implications remains to be seen. There are plenty of other well known factors that influence codon usage, and nobody in their right mind would consider calling any of them a "second genetic code".
/agreed. |

They can mine any SHA-256 coin such as bitcoin, terracoin, zetacoin, devcoin, freicoin, peercoin etc. However, they cannot mine scrypt coins such as litecoin.
