I was finally able to pull nearly a solid mh/s from one 290x for over 6 hours stable Cheesy

I had instaled Water cooling and after that Cgminer only starts with black screen (no stats)
It starting like before - check pools, etc.. but after that only bin file is created and seems that GPU calculated something but - no stats at all.. i cant see HashRate

Sounds weird, but plug the fan in, then remove it. Do this after windows has booted up.

After you've done that, start cgminer. No more black screen. Grin

I am using one of these so I no longer have to plug a fan in.
