Dell T7910 installed GTX 980 - not working

Installing a Nvidia GTX 980 video card into a T7910, the computer will not boot. Just sits there with the power on. Power light on, no indications of anything else.

Any suggestions?

We never tested consumer video cards in this model, only Quadro video cards. In what slot on the motherboard was the GTX 980 installed? It should be in the blue PCIe x16 slot and no other video card should be installed.

Yes, installed in the PCIe x16 slot. no other video cars. No Joy.

I tried a GTX 660, works fine, with bench marks about 42% higher than a Quadro K2200.

We know it is not a power supply or slot issue so the incompatibility may lie with the T7910 system bios.

UserBenchmark is showing the benchmarks in a Dell Precision Tower 7910 with a GTX 980?

The GTX 980 is working now, the first card was bad.

Hey demoore58, how did you get the card to fit in the case?  The rise of the card is to high to get the case door on the T7910.  Any ideas would be very helpful Smiley Happy

The card from EVGA fit's in OK with the card right up against the rubber pad that's on the door.

I've used GTX Titan and GTX Titan X (new gen card like your GTX 980) cards in T7910's and they work great. I have seen exactly what you have reported here using a 4k Displayport monitor though, and the workaround for me was to connect to an older monitor with a VGA or DVI cable for initial setup and configuration. Then once your Dell bios settings and NVidia GeForce drivers are all working, you can cut back over to your high end monitor(s) and Displayport or HDMI cables.

Jim

RE: Dell T7910 installed GTX 980 - not working

I'm trying to get a new GTX 980 to work in a T7810. I've attached two power supply cables to the card (one to the 6pin and other to the 6+2 pin connector). I have the 825W power supply.

But I'm still getting a ""Please power down and connect PCIe Power Cables For This Graphics Card" warning at startup. 

Is there something else I need to do? I guess maybe I have a bad card -- but it seems as though the power supply should support this.

Thanks for any insight...
