Title: Can only get 2 out of 4 cards running - Please help! Post by: markonegolf on February 03, 2014, 08:41:38 PM I have 4 Asus R9 280x GPUs and I can only seem to get two of them running. Both green lights and both fans are working on all the cards except Windows and CGminer is only detecting 2 cards.
They're connected to a Asus P8Z68-V LX motherboard with PCI-e 1x powered risers. I've changed the BIOS settings to allow the 1x slots to be active. Would the installation of jumper cables on the 1x slots be necessary? As described here: http://www.gobitgo.com/articles/1001/How-To-Correctly-Use-and-Install-PCI-E-Riser-Cables/ Other specs include i5 2500k, 8GB Corsair RAM and Dual PSUs. Thanks in advance!
