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.
