stickg1 :
Did you try the second card by itself? Also try a single card in the second PCIe slot. These will help pinpoint the problem.
Yes, I tried moving both cards to each spot and they both run perfectly on their own. I have also tried messing with the NVidia Control Panel settings to no avail.
I have also went into the BIOS and disabled the onboard sound and the crash still occurs. Could the answer be in "Under clocking" the cards???
Thinking and looking for guidance.
