Title: [LTC] High Percent of Rejected Shares
Post by: magixx on April 06, 2013, 07:00:53 AM
I've noticed that I am getting a very high amount of stale shares with my HD5830s and I don't really know what it could be, my GPU settings seems reasonable based on the Mining Chart (https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison) and my router load is low. I'm getting about 290K per card which seems accurate for the settings but I would have thought I could get even more and even with this setup I am getting many rejections of unknown-work or prevhash-stale or prevhash-wrong.

Code:
cgminer settings:
--api-network --api-listen --scrypt -o kattare(I use it due to US location) -u u -p p --thread-concurrency 5728 --gpu-engine 890 --gpu-memclock 1205 --lookup-gap 2 --shaders 1120 --autofan -I 18 -g 1 -w 256

Temperatures are <80*C
My set up is Ubuntu 11.04 x64 11.11 Drivers and 2.5 APP SDK and cgminer running on 4GB USB 2.0 drive.t

What can I change to stop getting so many rejections?

Are using stratum?

I switched over to give-me-ltc which has stratum and that fixed everything.
