Title: 970 extreme 4 will only recongnize 1 of 4 7950's
Post by: rolyasm on January 07, 2014, 01:49:30 AM
Hi all,
  Just got though with my rig yesterday. Seems to work well, even had cgminer up for awhile, but my Mobo won't recognize my other three Sapphire 7950's. They don't show up under my Device manager. I tried a quick fix I read about putting a 75ohm resister in the DVI, but that didn't activate the card. Are there specific PciE slots I have to use?  Any jumpers or anything I need to setup? I did just update the bios. Nothing. My setup is using the 970 Extreme4, AMD 145 Sempron, 4xSapphire 7950's on powered risers. I do not have the Crossfire cables attached. All fans are working. I have an EVGA 1300 PSU. Don't think it is a power issue.
Any suggestion?
Thanks in advance.
