Well I am sad to report that my GR card is no longer recognized by any system after I plugged in an additional fan to the board (fan 2 header). I am now at a loss. The board powers up with the normal lights and the normal indicators when USB is plugged in. after that, nothing is recognized.

What I did to "cause" this...
1. All systems running stable ~600GH/s @ ~90C @ 800MHz
2. Power Card down
3. Plug additional fan into fan2 header pins
4. Power up card (new fan was spinning)
5. nothing, card usb not seen by multiple systems.

Anyone have any troubleshooting ideas here?

I contacted Ken and company but have had no response.

My card was running off and on (off for liquid block placement) for roughly <2 weeks total.

Thanks!
