To anyone with a 5770: A core overclock up to around 40 is the sweetspot to gain a few kh/s, any further and kh/s decreases. (At least for me) Example: 875 MHz gets me 202.5kh/s 885 MHz gets me 205.5kh/s 900 MHz gets me 180kh/s Seems to be the same way with memory too. Actually, exactly the same. So more tweaking has pumped 452kh/s out of my two cards (6850, 5770). Edit: I'll make a new build with the new commits when I wake up. I like staying updated.  |

In my opinion once asic hit, all gpus will be targeted on litecoin. Just a hunch.
Interesting. I think I'll buy a few. Does this mean litecoins value will increase? I can't imagine how hash-power should affect value? i think litecoin is CPU mining only. some high end cpu is best for litcoin i thought i read that somewhere It used to be cpu only, but a gpu miner was released (reaper) a few months back. Now there is cgminer for it now too. |

Tittiez also helped me and nearly solved it for me so I appreciate that too  No problem. |

And actually it's not normal..
50 KH/s is half of what a 6570 can get...
I'm not fuckin stupid I know the difference in scrypt/SHA256
If 6570 Bitcoin Hashrate = 100 MH/s then Litecoin Hashrate = +/- 100 KH/s
Is everyone on this forum a fucking troll..
Go back under your bridge scrub nub..
I thought the 6670 was what got around 100 MH/s, geez I'm trying to help. Like I said, try other concurrencies. |

It's for when you use the version that includes scrypt but do normal BTC mining.
Oh, well its there if anyone wants it. |

I said what card I am testing...
Sapphire AMD Radeon HD 6570 1 GB GDDR3 (650 MHz Core / 1800 Mhz Mem)
It crashed if I use intensity of 16 or higher..
It won't mine with 128 workload..
Switched to 256 workload and 15 intensity.. only getting under 50 KH/s..
Pretty shit so far if you asked me..
6570 isn't really a good card, 50kh/s sounds about right. Maybe try changing the thread concurrency? Try 6144, or 4096. |

You should clean up the OP graet.

RTFT?
"read the fucking thread" it means, what card are you using? |

There has been more pools for alternative coins popping up, so maybe a subforum for Pools might be a good idea. There is lots of discussions and threads that go on in there and the pool threads just kinda get in the way.

Now pool is back online on new hardware and new domain: http://ltcmine.ru/P.S. shares difficulty set to x256 in comparison with minimal difficulty. Sexy |

Pool is dead. Another one ddosed?
Yup. He's dead, jim. |

Supa's everybody's best friend in the btc-e chat, we all love him!  |

Haha! I'm blind thanks. OK got it compiled but no dice, anything over 2048 thread-concurrency throws gpu errors and fails, with 2048 it runs but has all rejects. This is with ubuntu 11.04 with 11.12 drivers and 2.4 sdk probably needs the latest driver/sdk or I just effed it up but it compiled with no errors, I already had reaper compiled and running on here, it seemed to run ok so I just thought I'd give it a shot. I had concurrency problems but 12.6 and sdk 2.6 fixed them. |

Isn't it interesting how litecoin didn't drop much at all when bitcoin took a plummet a day or two ago. Hmm...  |
|
|
|
Heh, thats funny. I've finished tweaking with exactly same results for 5770. Drop the voltage to 0.960v btw, it's stable for mine.
Not on mine, but 1.0v is fine. (My card never liked low voltages ) Edit: Nevermind, won't work with 1.0v either. Haha My Asus 5770 came with a STOCK voltage of 1.25v, cgminer doesn't allow above 1.2 so its set to that while mining. |

Feature request, a calculator that works with each chain, so, you know, you can calculate how much you will earn.

So that Low stale rate you would say is a good thing then huh
Well actually it was just the settings I had with reaper, now I'm getting ~1% with cgminer, but I'm pulling an extra ~40kh/s so it's worth it. |

I found some REALLY interesting results with my 6850 and my 5770! 6850: https://i.imgur.com/fZgEk.png5770: https://i.imgur.com/ti0Cr.pngSo, the memory clock on the 6850 had no effect on my hashrate (at least at those high settings)! I set it down to 500 and the hashrate didn't change. Now I wasn't paying attention to the share count, but it seemed to be sending as much as it should be. Overclocking the memory of a 6850 reduces hashrate. Likes worksize 128. The 5770 isn't like that. Higher memory doesn't change hashrate, but lower memory clock lowers it. Two threads pulled an extra few kh/s. A concurrency of somewhere in 3000s is what your looking for, for the 5770. Likes worksize 256. I'll do more testing later, but I'm happy with my results. This is amazing, great work ckolivas. And it seems stable already. |
