Title: 2 R9 280 GV-R927XOC-2GD Post by: lilfooker2469 on January 11, 2014, 03:20:57 PM I bought 2 R9 280 GV-R927XOC-2GD gigabyte cards. when i have them both on the mobo and try to mine litecoin the reboot the computer, so opens cgminer nothing but he cgminer 3.7.0 on the cmd window about 1 min goes buy then reboot my computer
i removed one and it mines fine , swapped and the other card mines fine also. i tried different driver, different cgminer (currently using 3.7.0) even bfg miner. also tried riser and swapping where the sit on the board the psu is 1000 4 gig ram gigabyte mobo 1 core cpu im pretty much lost on how to fix it any ideas would help EDIT : i got it to start mineing low hash rate by running cgminer -o -u -p then turn the intestity up to 13 on the first card only hashed at 256 khs max try turning the 2nd card uo to 13 and rebooted. |
