Title: Has anyone had this problem? Post by: Merchlewitz on February 14, 2014, 01:26:50 AM So when i start the cgminer up 1 card accelerates faster then the other.. then when they top out one card seems to stay constant in this case GPU 0 and GPU 1 flucuates all the way from 690-780. I'll post a picture of it and my settings any help is appreciated these are 2 r9 280xs. Here are the settings I'm using: C:\Users\MerK\Desktop\cgminer\cgminer.exe --scrypt -u Merchlewitz.MerchlewitzLTC1 -p x -o stratum+tcp://us-east.multipool.us:3352 --gpu-platform 0 -d 0,1 -w 256 -v 1 -I 13,13 -g 2 -l 1 --thread-concurrency 8128 --gpu-memclock 1800,1800 --gpu-engine 1141,1141 --gpu-powertune 20 --no-submit-stale --auto-fan --failover-only -o stratum+tcp://us-west.multipool.us:3352 -u Merchlewitz.MerchlewitzLTC1 -p x

try to switch those cards, are they on risers? Try to switch risers, could be a PSU problem. What models of 280X you have ? |
