Through some stroke of luck, I now got everything to work!!!!1!1!!1!1!2!1!1!
Intensity: either 16 or 17 works
Thread concurrency: 16384
Lookup gap: 2
Shaders: 1024
Now I can OC and then tune my new R9 270!

Okay, guys, I solved the problem long ago!!!
I just added a new ASUS Radeon R9 270 today. It gets no HW errors.
However, it seems the adding of the new card is now causing the old Sapphire 7850 to get HW errors once again.
I will read the wall of text above, and come back.

Why do manual payments need to be manually approved by the owner of the pool?
|
|
|
|
|
I just had 10 minutes of stratum downtime right now.
Not only is the website not reliable now, the mining is also failing. But I'm glad I just found out how to set failover pools in CGminer.
When will the new server arrive? And today, there seems to have been a lot of orphaned blocks.

How can I withdraw my coins from the pool (get a payout)?
I don't see any button on the web site for doing that.
Threshold set to 10 SXC now. Just set your payout address and automatic payout threshold to anything you want (under My Account page). If you reach that amount, you will be payed automatically. Thank you. |

My current list of things to try: - 1. Set thread concurrency to 4100
- 2. Set thread concurrency to 4098
- 3. Use CGminer 3.1.1
- 4. Use CGminer 3.0.1
- 5. Install Catalyst 13.9
- 6. Install Catalyst 13.4
- 7. Install Catalyst 12.8
- 8. Install Debian Linux on a different partition, and use it to mine

have you tried the launch settings?
What are these? |

Okay this is what i use: GUI-miner-scryptDownload that and use the cgminer within it create a .bat file with the following; cgminer.exe --scrypt -o stratum+tcp://stratum.wemineftc.com:4444 -u Hammereditor.main -p 1357 -g 1 -w 256 --thread-concurrency 16000 --auto-fan --gpu-powertune -20 --auto-gpu -I 13
let me know if that works or not I am currently using GUIminer-scrypt, but I'm only seeing a 40% improvement in hardware errors. So it's not helping a lot. |

hi,
i had the same issues with my 6870's
try going to start -> run -> cmd.exe and typing the following (should say value saved)
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
solved all my issues with what your getting right now
if still a few hardware errors are thrown up, try adjusting intensity manually between 10-19 and seeing if theres a sweet spot (mine was around 17)
best of luck
Like I said before, adjusting the intensity and doing the 'setx' commands did not work. |

Try this: amd app sdk 2.7 catalyst 12.8 and cgminer 3.0.1 or 3.1.1 as in this thread: https://bitcointalk.org/index.php?topic=179718.0Other think to try is if the card is seated properly You need a multimeter for the rails, but the software first. Okay, I'll first try the latest Catalyst driver, then go to 12.8. I'll change the CGminer versions first. And GUIminer is not helping the errors much. |

Which version of 7850 graphic card do you have? If it's 1GB version (like mine) try "thread-concurrency 8196" , 8192 gives me a bunch of HW errors but with 8196 i have 330 kh/s and no errors.
Okay, I'll try this. I will also try 4100 and 4098. I have the 1 GB version. |

Change the intensity (the -I #number) depending on how far your card can go and how unresponsive a PC yourself can put up with.
No matter what I set the intensity to, the amount of HW errors is the same. |

Both pools have notoriously bad predictions of estimated mining power. I mine at 220 kh/s and it displays me at 50- 150 kh/s. You should not trust them below 500kh/s. I do get the expected amount of coins based on ltc and ftc calculators. How far are you of of the estimate by the calculators? Some points: - Update video/open cl driver - What are the PSU line variations - PSU health? - Revert to cgminer 3.1.1, most stable for me. - What is the cpu load? Not cpu mining as well right? Try it without cpu loading. if i fixed it: 14e4VVFM9eHdunHxpGgswBf4N4iiVdmeMD  The calculators say 0.15 LTC/day, but I think I'm earning about 1/3 of that. The CPU load is always 5% when GPU mining. I don't CPU mine. The system has 4 GB RAM, but only 2 GB is being used while mining. And the PSU is a Raidmax 630w; never had any problems with it. How would I find the health of the power supply? And here's CGminer with the --verbose argument:  |

Use an older version of cgminer... 3.1.1 for example
Do you know any versions of CGminer which are known not to cause a lot of issues? |

Although this story involves mining Litecoins, not bitcoins, I think that the logic here is the same. I started mining Litecoins and Feathercoins about 5 days ago. I wondered why my mining pools, WeMineLTC and WeMineFTC, always showed my hash rate as 80 Kh/s, although GCminer 3.7.2 reported 330 Kh/s. So today I made a small Node.js program to interact with the CGminer API, and it seems that the mine program has a large rate of hardware errors. There's about 2 new errors every second. Of course, no notifications about this appear in the console window, so I never knew about it. I also noticed that the amount crypto-coins I was earning each day were lower than expected. I am not happy about what is happening to all of my hard work. Command-line arguments: start CGminer\cgminer.exe --scrypt -u Hammereditor.main -p 1357 -o stratum+tcp://stratum.wemineftc.com:4444 --intensity 13 --api-listen --api-allow W:192.168.1.2 --api-network
Regardless of which pool I use, the error amount remains the same. I thought this was due to overclocking, but I lowered the speeds to default, and then increased the voltage on top of that. But that changed nothing. Video driver: AMD Catalyst 13.9 RAM: 4 GB OS: Windows 8 x64 So how would I fix this Edit: the person who gives a solution which fixes my problem will be rewarded 0.002 BTC ($2.00)! |

I am planning to get a video card to mine litecoins in 1 month. I don't know if I should get a 7870 or the new R9 270x. The R9 is basically a re-brand of a RHD 7870, so I would expect it to have the same hash rate. However, https://litecoin.info/Mining_hardware_comparison. .says that a R9 270x gets 475 Kh/s (1120 MHz), and a 7870 (1120 MHz) gets 385 Kh/s. So which one is better? On Newegg, a Radeon 7870 is $150, and a 270x is $200. |

Use the money to buy bitcoins and hold till their value appreciate.
The ROI for miners order now and deliver at an unknown time (end of the year if you are lucky) is so small that you would be lucky to recoup your "investment" in the foreseeable future.
Here's my final descision: I will continue saving money, but in the form of bitcoins. You know how, 3 days ago, the price of bitcoins went down to $96? When something like this happens again, I will convert my money. I will keep trading until I have enough bitcoins to get a butterfly ASIC. That way, I can choose to get the miner in the future, or have my bitcoin investment ready for a return. |

Short answer : no definitly not worth it.
Additionally, I don't have to pay for electricity. Even if it was earning only $5/day if/when I got it, that would be great. All Avalon products are too expensive for me. I want something which is under $325. No it is more profitable to buy Bitcoins
I'll try to convert any real money I can get into bitcoins, because the exchange rate is likely to increase in the future. I will then convert those into real $ at the time of purchase. |

Right now I only have $55 in both bitcoins and real $, so I cannot get yours, let alone one from BFL. |
