Its because the DVI one is "first" port. If you unplug the DVI the DP should work normally.
I tried this.
I can not get ANY of my cards to post BIOS.
Removed DVI-D nothing..
I ended up just using the DVI-D port and Display port on my other monitors.
Also.. im having some issues.
Issue 1:
GPU Shark 0.9.1.4 seems to FLIP my card numbers arround.
GPU1 is actually GPU2 when compared to EVGA Precision X 16.
I am assuming EVGA Precision X is more accurate as it is displaying the proper temps for the card.
Issue 2: These cards in SLI on a single card spacing is CHOKING the top card causing my temps to SKYROCKET to 80C+ which then GPU sharks shows Thermal Throttle, and Voltage Throttle.
Which to me makes me worried....
(my waterblocks come in on wednesday, so this problem will fix itself, but sort of scared about the load temps until waterblock arrives)
Issue 3: I used to have a dedicated PHYS-X card... 550Ti.
344.16 will not detect the 550GTX at all... The card ends up being disabled on top.
(edit... it appears 344.16 ONLY supports 980/970... sigh... i need a 344.11 for 550Ti support.)
Issue 4:
Power Saving mode on Card 1 will not go lower then 25.6% TDP (910CLk/3505Ram), vs Card 2 which goes down to 7.8% (135CLk/324Ram)
Is this because i have 3 monitors connected to Card 1?
Adam, do you notice any of these problems as well?
