Hypertransport Sync Error!

I very recently plugged a second 460 GTX 1GB into my computer for dual SLI. It is now returning a "Hyper Transport sync flood error occurred on last boot." When I put said second 1GB card into my rig, I took out a 460 GTX 768mb that I was running dedicated for NVIDIA physx. My PSU is a OCZ 700w. What's returning this error??

  1. Have you OC'ed your CPU/RAM? Since Hypertransport handles the communication between CPU-RAM-GPU (PCI-E lanes to be more accurate) that could be causing the issue, even if u haven't OC'ed your PC try entering BIOS and load default settings, some value might have changed at some point regarding HT. If u can't get into BIOS try clearing your CMOS.

    I just tried resetting BIOS, no luck. However I did notice my BIOS version was only 1.1. In attempt to update or at least see what kind of board I had with CPU-Z, I took the second card out, and tried to turn my computer on. Which worked great, except there's no feed to my monitor through mini-HDMI anymore. Any suggestions?
