WHAT AM I MISSING?

[Joseph Combs]

Question: I bought this Nvidia MSI GeForce GTX 1080 Ti Aero OC Edition card from Ebay and put it in a new build with the following specs:

Gigabyte Aorus Extreme X399 Motherboard
AMD 2950x Threadripper CPU

• Seasonic PRIME Ultra 850W 80+ Titanium Power Supply

• G.SKILL TridentZ Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200

• Arctic Freezer 33TR - Tower CPU Cooler for AMD Ryzen Threadripper sTR4

• SAMSUNG 970 EVO M.2 2280 1TB PCIe Gen3. X4, NVMe 1.3 64L V-NAND 3-bit MLC Internal Solid State Drive (SSD)

The box booted okay but the card did not send output to my monitors, replaced with RX480 and monitors displayed output. Am I wrong in concuding there is something wrong with the card?

It would appear after doing some research that this is a widely experienced problem with the 1080TI ..... have some things to check when I go home tonight.

Thank you to all the extremely helpful people on this forum!

You try a CMOS reset?

I didn't get video out of my 2080 Ti when I first installed it, had to cycle through a couple of CMOS resets before the motherboard finally decided to output video to it. Sometimes motherboards don't like new hardware for some reason.

Also try HDMI if displayport isn't working, some cards just don't output video through DP until you boot to Windows. If you want to see something during boot you may have to use HDMI.

I put my rx480 back in and moved on. Will go back to it shortly. Will probably end up flashing the forward on the card
