I installed my second Gigabyte 560ti OC card and set it up with an identical one as SLI. Everything is working fine, but the RPM on my second card is showing up as 0 RPM. I have the XFX 780i SLI board, and to troubleshoot it, here is what all I have done for now.
results : 560ti(2) has 0 RPM
results : 560Ti(1) has 0 RPM
560ti (2) standalone
results : All fan speeds available
560ti (1) standalone
results : all fan speeds available
I tried using another SLI bridge, but the same results, the card at the bottom would come with 0 RPM's on it. I have used Furmark, HWmonitor, GPUz, same results, running Windows 7 RTM x64. Any suggestions if it is the motherboard, or the PCIex? I cannot use the middle lane because I do not have a flexible SLI bridge. Also, my motherboard gives me a warning that I need to move my GPU on my PCIEx lane 1 if I try to run it in standalone mode and put it either the PCIEx pane 2 or 3. Could it be a bad PCIEx lane 3 on my board? If that is the case, I would buy one flexibile SLI bridge ASAP and use it in Middle PCIEx.
