My 5830's are finally being shipped out so now I'll put about 600mh/s into this.

Is there any type of a PCIe splitter that'd make one slot into 2? I forget the thread but I thought someone mentioned something like that.
|

I can only imagine there's an error somewhere:

idk what's wrong but this morning I had 12% rejection. Sucks.

Question - PCIe 1x and 4x will work fine, right? Looking at getting a cheap machine with 1 x16 slot and 1 x4 slot. This is the board:  From left to right, I think, x4, x1, x16 Just wanted to make sure that this WOULD, in fact, work. I was reading this thread: https://forum.bitcoin.org/index.php?topic=14910.0;allAbout someone funding an ASIC setup. Paying attention to that one. |

I am over 300ms away from bitcoins.lc and I still only get 1% rejection rate, I am not sure it is purely latency you have a problem with
How'd you check that? Any other ideas what it could be? I guess I could try underclocking. |

meh, no change. This morning it was at 7% rejected.

That's cool, I didn't realize you could mine with anything other than x16. Should open up a lot of cheaper motherboards for me.
What about cards, I think you can but wanted to check - can you have a 5870 and a 4870 on the same motherboard and crossfired together?

Thanks, that actually didn't answer anything. I can definitely look this up and do research though. Sorry to bother you. |

ran -a2 at aggression 8 for a while with 100% accepted. Going to run it at 12 aggression overnight to see how we do  Thank you for the very promising help. I'm pretty confident that this will solve that issue i was having. |

So, I know PCIe x16 is ideal for mining but what about PCIe x8 or x1? Can you use them? Are they efficient enough or should I be looking for dual/tripple/quad PCIe x16?
What about these PCIe extenders? How do they work?
Also, I heard something about ASIC for mining. What is ASIC and how do they work?

What's the deal with the warnings on that page? |
|
|
|
I'm getting about a 5% rejection rate
Going to add flag -a2 back in cos I think I was getting lower rejection rate with that before OS reinstall
I'll have to look at how you do that because that'd give me something else to try out. |

Ran aggression 12 for 30 min or so, averaged 10% rejected.
|
|
|
|

I ran aggression rate 11 last night and got 5% rejected this morning. It's an improvement but still rather high. I'll mess with different aggression rates.

Just updated drivers for the 4870, will mine it for a while to see if it helped. Otherwise, I have QOS on my firewall so I'm wondering if disabling that would help.
Any other ideas?

I'd need cash to set up another machine for you plus electricity costs but otherwise I could administer one for you no problem.

gnna throw 1.8 ghashes here to test seems like everyone is happy and the operator is active EDIT: just tested, it seems like it takes longer for me to submit a share here than elsewhere..about 30-40 seconds for work..thats weird... My rejection rate is 10%, wonder if that may have something to do with it. I need to start running phoenix from command line to dig into it further I think., |

This morning I woke up and saw it was right back at 10% rejection.
I may just try switching pools. Are there any other things it could be?

I would go for the 6870. They perform better, are more efficient, and better for gaming as well. One more thing, you may want to re-think about using that setup for mining with the next difficulty increase coming today. Difficulty is getting to the point where anything under 1ghash isn't really worth it  Which is why I opted for the 5830. According to this it's pretty darn efficient:  Not to mention the fact the 5830's are $100-$150 cheaper than both the 6870 and 6950 |
