Mining Machine Hard Lock - HELP!

[laharian]

Hello all,

Yesterday i got my x3 AMD R9 290 cards. 

Everything was working great on my single Gigabyte R9270X.

I removed the the 270x installed one of the 290 with the same power riser, installed drivers, now the rig likes to hard lock randomly and cgminer will not detect the 290.

Any help would be greatly appreciated.

THANKS!

Did you say you had 3 290's? If so, do they all do that, or only 1?
