980 ti runs on 16x1.1 under load

[Pat-Roner]

Hi,

 

I got a Gigabyte 980ti extreme connected to a msi z170i itx board. 

 

I'm running win10 with latest Nvidia driver installed (361.91), and gpu z reports that my card is running on 1.1 istead of 3.0.

This is also under heaven load, AND when I press the question mark to start the render.

 

Any ideas?

Update/clean install drivers and motherboard BIOS. Have you noticed any low performance?

I've updated the Mobo to the lasted BIOS, but I can try to clean install drivers.

 

Yes, only 17k firestrike with 1525mhz OC.  - http://www.3dmark.com/fs/7619219

Those scores don't seem wrong, really. There's hundreds of users with the exact same setup getting the same scores or worse. A few users around the same score as you are getting lower graphics scores, but higher physics scores. 

Run GPU-Z's render test and see what the PCIe speed says. Also, monitor the speed of the card with GPU-Z when the card is under load. It may be set to 1,500MHz, but it may not actually be running at that speed.

To me it does. - heres a run with my previous 980 ti at 1305mhz http://www.3dmark.com/fs/5376480

 

But according to this there dosen't seem to make that big of a difference. https://www.techpowerup.com/reviews/NVIDIA/GTX_980_PCI-Express_Scaling/21.html only 3% on 4k.

 

But theres something going on, since I have a custom preset which I run after OC, and that has all of a sudden dropped 150pts.

Have you checked to make sure the card is fully seated? My 970 had an issue with flexing and pulled itself out of the slot over time. It would report random pcie speeds from x8 2.0 to x16 1.1 constantly til I figured out the issue.

Just tried, and still the same problem. I was able to press it in a little bit though!
