Hi;
I added a 1250 Seasonic PSU and HD7970 to my crypto coin mining rig last night.
My existing card is a 5970.
When I have both cards sitting on my Rampage Extreme IV Mobo I get no video. I've tried with and without cross-fire. They work individually (if I fully remove the other card).
I've tried setting the 5970's lane to PCI 2 in the BIOS and tried different lanes with no success.
I know other people have had these two cards working together in their rigs so I'm wondering what I'm doing wrong.
Any advice?
