This is an NVIDIA related driver thing. It isn't really a driver bug exactly, but it becomes a problem when software engineers (Precision's developement team in this example) assume that the first video card entry is #1 and the second entry is #2. In reality, the cards could have been stored in the driver's hardware index in any order. The easiest solution would be for Precision's software developement team to incorporate an option to switch the order the cards are listed. Until then, the only "fix" that I know of is for you to simply remember that the order is reversed.

Since this has been a known issue for at least a year, I wouldn't hold my breath for NVIDIA or EVGA to create a fix.

You might as well switch to Afterburner.  As I said, this will almost certainly not be resolved any time soon.

Same here with my Sigs. It is VERY annoying. I already posted here about this issue, but nobody cares...
 
Have a look to device manager. Right click the GPUs, you should get the same wrong order (Bus PCI #).
 
This seems to be a very common issue. Many monitoring apps do not report correctly multi GPU setups. I don't think it is mobo related, but software related.
 
CPUID HWMonitor gives correct results (GPU 1 is first, GPU is 2nd and so on). Have a try.
 
The reason is lazy use of NVAPI, or NVAPI bug.
 
Technical hypothesis (and workaround for coders : it worked for me) :
 
The enumeration function NvAPI_EnumPhysicalGPUs() fills an array with physical GPU handles, and gives the GPU count. (these handles are needed to communicate with GPUs). But the array is not sorted. Most monitoring applications consider that 1st physical GPU handle matches the 1st slot, 2nd the 2nd and so on. This is untrue (the array seems to be filled more or less randomly by the driver call). Another function has to be called to get the bus ID from the physical handle : NvAPI_GPU_GetBusId(), and the array has to be sorted according to BUS ID. (a simple bubble sort and bob's your uncle... ). Even device manager don't care about this.
 
I just read NVidia documentation, and I wrote my own tiny monitoring app using NVAPI so I get the correct order. (hopefully I am only interested in temps : o/c functions need the top secret "non disclosure" API).

Note: he provided examples which are easily reproducible and even provided a solution which he tested by writing his own monitoring application.  How much easier could he have made it for the Precision development team to research and correct this issue?  Instead, "nobody [at EVGA] cares".

I don't see any mention in the changelog indicating that the GPU order thing has finally been fixed in the latest version.

It is really not a big deal.
Just wait and see what happens when you TRY to run GOW4 with a GTX 1080Ti Graphics Card.

blaming evga or nvidia for an issue caused by windows itself.....

I also have this problem currently with my two GTX 1080 Ti FTW3's using Precision XOC 6.1.6. If there is a simple registry value to change or something I would do it myself. Anyone know of where the values may be stored?

They need to Blame Someone, it is the way of life now.
Not many users clean out or Delete the Video Key, I do this between each driver change.
It is to bad that DDU does not clear this Registry Key.

What do you mean by clear out or delete the video key? I'd love to try this to see if I can use it as a fix for mine. My video cards have reported as "swapped" in the nvidia control panel for more than 2 years :P lol

He is talking about deleting the video key inside the registry...

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video (highlight the Video key and press the delete key.)

NOTE: When deleting the video key you will be prompted with an error saying "Error deleting key, Cannot delete Video: Error while deleting key." Just ignore the error and select OK, all keys within the Video key will be deleted except for ones that cannot be deleted.
