Hi. I recently bought the Gigabyte Geforce GTX 770 4GB GPU. I have a MSI Military Class II P67A-GD65, 16GB RAM, and a RS600-PCARE3-US PSU. My old GPU is a MSI Twin Frozr II. When I use the new GPU I get a B2 error after the beep when starting up my PC (Doesn't make it to the BIOS option). I use the 6x2 +2 PCI connector for the new GPU. Everything works when I plug in the old GPU with the 6x2 PCI. I was wondering if anyone has seen this issue before.
