Title: Mining Litecoin solo, lots of reject blocks! Post by: mc_lovin on October 12, 2012, 06:00:22 PM Hey we are solo mining litecoin over here and we have over 100 reject blocks with 3-4 GH/s over the past few days.
Any idea why we are getting so many reject blocks? We got 1 block confirm in the first hour, and now its rejectsville! Title: Re: Mining Litecoin solo, lots of reject blocks! Post by: Come-from-Beyond on October 12, 2012, 06:34:52 PM Someone attempting 51% attack?

I think you mean MH/s not GH/s ;) Don't know, when you mine at a pool do you receive high stales/invalids? Could be caused by an incorrectly configured miner.

Reduce intensity to 11 for Radeon VLIW 4, 5 or to 12 for GCN cards and try again Title: Re: Mining Litecoin solo, lots of reject blocks!

Litecoin mining is so complicated.. Pretty sure it's configured correctly. update: just put it on pooled mining and im getting rejected shares like a mofo! any tips? intensity too high you say, eh, ill back it down a bunch and let you know!

First you need to tell us what cards you are using. Title: Re: Mining Litecoin solo, lots of reject blocks! Post by: jasinlee on October 12, 2012, 10:36:02 PM I pounded my head on this all night 2 nights in a row mclovin, when I got 6/8 gpus working the final 2 would become SICK or start hashing in MH or the threads would be killed. It was a pita, went back to btc mining until someone comes up with a memory stick version I can pop in and just buy that will run it in linux/ubuntu/whatever. I am offering 3btc for it if anyone is interested :)

First you need to tell us what cards you are using. Ah, any cards! There is a 3x 7970 box hammering away, a 3x 5830 box, and a 2x5850,3x5830 box. Confused I am, as to why this 2x5850,3x5830 box locks up so easily. With a conf like this (/root/.cgminer/cgminer.conf): Code: {Then entering: cd /opt/miners/cgminer export DISPLAY=:0 export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 screen -q ./cgminer --api-listen --auto-gpu --auto-fan I get happy times, but slow times. This will continue up to like 500-1000 shares per card easily, I don't have the patience to wait for it to get to that point for this screen: Code: cgminer version 2.6.1 - Started: [2012-10-15 20:47:55] Now if I take that exact same conf and change the intensity to 11 on all the cards, it locks up after awhile (but the speeds are much better, and there were little rejects). Code: cgminer version 2.6.1 - Started: [2012-10-15 20:30:02] So it looks like GPU0 and GPU3 are the 5850s. I'll try those two at 10 intensity and the rest at 11 and see what happens. I pounded my head on this all night 2 nights in a row mclovin, when I got 6/8 gpus working the final 2 would become SICK or start hashing in MH or the threads would be killed.

I am offering 3btc for it if anyone is interested :) I would like that device as well, a plug-n-play LTC miner, I'm sure someone will create it, but once someone does.. Think of how high the LTC network hashrate is going to get... The learning curve with litecoin is what is keeping the hashrate down (or not). Title: Re: Mining Litecoin solo, lots of reject blocks! Post by: bowen151 on November 13, 2012, 02:50:32 PM Reducing the intensity seemed to help me out a bit with the rejects. Still have a lot of them though!
Id love to see a miner/pool combo like bitminter. Its so easy to get going i always have to check if i forgot to click something :) Title: Re: Mining Litecoin solo, lots of reject blocks! Post by: Greedi on November 13, 2012, 02:54:53 PM did you compile with scrypt enabled?,what OS are you mining on?
Maybe get some help here (http://forum.litecoin.net/index.php) |
