Hi
I have an Asus Maximus Hero VI with Sapphire R9 290x and Cosair's HX850 850W PSU.
I recently got a spare 290x from my brother that I want to add to my desktop for mining. However when I install it into the second PCI_Ex16 slot, BIOS doesn't seem to detect it even though it works fine in the first PCI_Ex16 slot. Maybe the second PCI_Ex16 slot on the mobo is bad but how to be sure. Hard to tell. Never really used the second slot before. In BIOS, it says "Not present" when the second card is installed in x16 slot and connected to the PSU. By the way in dual gpu setup, I don't have a second monitor attached. I know Windows may have an issue finding it but BIOS should, right? For Windows, I was planning to get a dummy plug with 68 ohm resistors.
Anyways, since I don't really care about x16 slot or data transfer speed to the GPU, my question is: can I use a powered 1x to 16x riser to just hook up the card on the 1x PCI-E slot instead?
Sorry newbie here. Thanks!
