Title: Re: Very high rejection rate. 5%-12% Post by: pandemic on June 14, 2011, 01:02:22 AM My pool right now is bitcoins.lc. Whenever I leave the miner going for 8+ hours, I generally have about 10% rejection even though everyone else in the pool is getting less than 1%
I'm starting to think it's a latency issue because sometimes I'll run it for 30 min or so and it'll be fine. Other times I'll get 20% rejection. Currently running a 4870 at 790mhz/790mhz mem at aggression 10 with phoenix and phoenix rising GUI miner. I've played with a lot of settings and nothing seems to help Title: Re: Very high rejection rate to bitcoins.lc Post by: SomeoneWeird on June 14, 2011, 01:06:24 AM My pool right now is bitcoins.lc.

I'll put it on 50% and run it for a while to see if that helps. Title: Re: Very high rejection rate to bitcoins.lc Post by: LegitBit on June 14, 2011, 02:02:40 AM 85C?!
Kick that up to 100% fan or plan on loosing that card in the next two months. 50-70C is the safe range. Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 14, 2011, 02:17:52 AM 85C?! Kick that up to 100% fan or plan on loosing that card in the next two months. 50-70C is the safe range. At 50% it's now at 60C. I don't care TOO much about this card because I have 2x 5830's on the way... as soon as they get more in. As I said, it's at 60 and I'm still getting 5.71% rejected. 89mh/s 66 accepted (94.9%) 4 rejected (5.71%) Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 14, 2011, 12:14:10 PM I ran the fan at 50% all night. Woke up and the temp was 62C so it was definitely cool enough. I still had 8% rejection rate.
Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 14, 2011, 11:38:32 PM Is this likely a latency issue with bitcoins.lc rather than a config setting on my machine? That's what I'm leaning towards.
Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 15, 2011, 12:10:47 PM 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? Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 16, 2011, 01:40:10 AM 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?

Title: Re: Very high rejection rate to bitcoins.lc Post by: willphase on June 16, 2011, 09:07:26 AM try playing with your AGGRESSION - it seems to affect stale rate for some reason.
Will Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 16, 2011, 12:07:17 PM 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.
Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 16, 2011, 12:48:47 PM Ran aggression 12 for 30 min or so, averaged 10% rejected.
Title: Re: Very high rejection rate to bitcoins.lc Post by: Oldminer on June 16, 2011, 07:46:49 PM 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 Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 16, 2011, 10:15:08 PM 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. Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 17, 2011, 03:57:35 AM 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. Title: Re: Very high rejection rate to bitcoins.lc Post by: pandemic on June 17, 2011, 10:38:48 PM meh, no change. This morning it was at 7% rejected.
Title: Re: Very high rejection rate to bitcoins.lc Post by: c_k on June 18, 2011, 11:32:03 AM 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

Any other ideas what it could be? I guess I could try underclocking. Title: Re: Very high rejection rate. 5%-12% Post by: pandemic on June 19, 2011, 03:52:45 PM idk what's wrong but this morning I had 12% rejection. Sucks.
Title: Re: Very high rejection rate. 5%-12% Post by: zimpixa on June 19, 2011, 09:53:33 PM Its phoenix itself. Try new version (1.5) or try poclbm.
Title: Re: Very high rejection rate. 5%-12% Post by: phelix on June 20, 2011, 10:39:04 AM quite high stale rate here, too.
deepbit: ~2.5% btcguild: ~4.5% Aggression at 12, with 13 it was even more. The phoenix flag -a has only affects the filtering of the hashrate for display. running phoenix 1.48debug btw., driver 10.12, stream 2.1, win xp. Connecting over wi-fi but I do not think is the problem. Slightly overclocked but temps below 80°C. I deactivated QoS just to check. If that is the problem I will send a bill to mircosoft. poclbm never recognized all GPUs. |
