Hi guys, newbie to the site here only semi new to alt coins.
I've been googling around to see if I could find a solution to an issue with my mining rig, I'm hoping someone here might be able to help =D
The problem I am having is, whenever I try to use risers, anything past 2 cards my rig won't see...
Current setup is
1275w psu
4x 7950s

I know some stuff like the board is overkill for a rig, but for my first mining rig build I wanted to keep things simple (no 1x to 16x risers, shorting pins, etc).
Right now (as some of my 7950s are 3x slot cards) I have 3 running in a custom case, if I use the risers (same cards, same slots) i can only see two cards.
If I hard plug in two cards, and plug in one via riser, I can still only see two cards.
I have no idea of my issue here. I mean the risers work... as long as I only use two cards.
The mobo is made for 4 cards.
The mobo has a molex in for extra power to the pci slots, so powered risers I would think should not be needed.
Anyone have any ideas or need any more info/pics? Am I just using the wrong risers somehow?
I appreciate any and all comments! Thank you!
