Title: Dual XFX 7870? Post by: haan on March 02, 2014, 09:28:29 PM Cant seem to get past 315 for gpu 0 and 300 for gpu 1. I have asked from different sources and tried different TC and clock settings to no avail. The settings on litecoin.info suggest this card gets 375. It seams as if cgminer isn't reading the setting in the bat file because the intensity always starts at 17 even if I set it differently in the bat file. Also, why are they different hashrates even though they are the exact same card and settings? I changed the settings in cgminer and made sure they are equally clocked.
My current bat file: del *.bin setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer.exe --scrypt -o stratum+tcp://global.wemineltc.com:3335 -u XXXX -p XXXX -g 1 -I 19 --gpu-engine 850 --gpu-memclock 1500 --thread-concurrency 16000 -w 256 Title: Re: Dual XFX 7870?

And speed can vary because one of the cards is driving monitor/teamviewer or just so the cards are a bit different. Title: Re: Dual XFX 7870?
