Where is the problem ? i have new bios and drivers. "Due to bandwidth allocation limitations, it is strongly recommended for users to install 3rd gen intel core processors to enable functionality in the third pci express slot" Words on MSI z77 mpower :(( So i must to buy minimum intel core i5 ????

Would the CPU cause a bottleneck for the hash rate? Title: Re: 3 x 7970 Problem with 3rd card ... Post by: vm1990 on April 08, 2013, 07:49:03 PM in theory there isnt a limit as its all GPU intensive so even a single core running at 1.2GHz woukd be enough
