Thunderbolt Headaches

Have an asus X99-E WS/USB3.1 Board, asus strix GTX 980 Ti in slot 1, 32 Meg Gskill Mem, Thunderbolt EX II card in slot 5, Samsung M.2 950 Pro 512 in the native M.2 slot and everything is working great with an Apple 27 inch Thunderbolt display all under Windows 10.
Problem is I can't manage to get the second Thunderbolt display to light up or be recognized. Ideally I will want three displays. I am obviously missing something elemental.
Any assistance would be more than a little appreciated.
 
I'm not really up to speed on Thunderbolt, but do they need to be daisy-chained? Does the 980 process the video and send it out the Thunderbolt card? Can't you just connect them directly to the 980?
 
No actually you cannot connect a thunderbolt directly to the 980 and they have to be daisy-chained. If its connected to an apple computer there is no problem and it works. The Asus Thunderbolt EX II card manual shows the daisy chain process. Sadly there is a hic up somewhere

You don't mention what your processor is. Does slot 5 on that mobo with your proc. have CPU-connected PCIe lanes? I'm sorry but I don't have time to do a lot of research, but that TB card has these qualifications:

Supports Thunderbolt™ 2 Interface* with max. resolution of 4096 x 2160@24Hz / 3840 x 2160@60Hz
DisplayPort 1.2 Multi-Stream Transport compliant; supports DisplayPort 1.2 monitor daisy-chain up to 3 displays**
* Use Thunderbolt™ cables to link Thunderbolt™ monitors and other Thunderbolt technology-enabled devices in a daisy-chain connection.
**Use the mini DisplayPort cables to link up to 3 DisplayPort 1.2 monitors in a daisy-chain connection.

But again I wonder, how does the 980 fit in? If it's supposed to process the video (not the TB card - I'm not sure if it works that way), then I think they both need to be in CPU connected slots.
 
Oh, never mind - I see that you connect DP out of the 980 to the TB card, then on to the monitors. Have you tried other slots?
