Title: Droping hashrate over time. Post by: soilworker on December 20, 2013, 09:30:49 PM Hi guys!
I'm pretty new to mining, and having some problems with my rig running 2x Sapphire HD 7950,PSU Enermaxx 1000w, 4 GB RAM runing both at 1200 kh/s, my hasrate is slowly going down over time, after 2-3 hours with more than 100 kh/s. I have tried everything, powermode is at maximum, my cards are quite cool, about 73°C and don't have any idea how to fix that... timeout /t 30 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer --scrypt -o stratum+tcp://doge.poolofpools.com:3337 -u x -p x --thread-concurrency 21712 --intensity 19 --worksize 256 --lookup-gap 2 -g 1 --gpu-engine 1080 --gpu-memclock 1250 --gpu-vddc 1.087 --gpu-powertune 20 --temp-target 75 --temp-cutoff 90 --auto-fan --failover-only -o stratum+tcp://stratum01.hashco.ws:8888 -u x -p x Not using Trixx and i didn't undervolt the GPUs. What i spoted is, when im opening the windows and the GPU's and Fans are getting cooler, tha hashrate is dropping slightly... Next thing to ask is before finding a block, if i close cgminer, do i get anything after finding a new block, or im loosing all my shares? Thank you in advance! Title: Re: Droping hashrate over time.

Thanks you Lk79fD5ih15Moo73Th198mp3EU6BGqLoRq Title: Re: Droping hashrate over time. Post by: CaptainBeck on January 21, 2014, 12:23:00 PM You could setup cgminer to kill and rerun every few hours if you know a refresh start fixes everything.
I've got mine as a windows service, which kills every 4 hours and restarts so i dont have to worry about any bugs creeping in there. send somthing Thanks you Lk79fD5ih15Moo73Th198mp3EU6BGqLoRq Also....... ahahaha nice off topic random beg, wonder how well these work. |
