GTX 1080 with Qnix2710 - DVI to DP/HDMI and OC?

[dante`afk]

Hey folks.

so the GTX 1080 has only 1 DVI port, a couple of DP and one HDMI port.

I am running 2x Qnix 2710 which are able to run at 120hz.

So due to the new GPU I am forced to hook it up either at the DP or HDMI. If I hook it up on DP (dvi to dp converter) I cannot overclock it, even 5hz more results in a blackscreen. On HDMI (dvi to hdmi cable) there is no screen at all.

Is there anything I am missing or is OC not possible via DP?

These are the cables I got:

Do you think this cable here would make any difference? DVI to DP cable

Those are all single-link adapters. You need a dual-link DVI adapter like this one: https://www.amazon.com/dp/B00856WJH8/?tag=mtests-20#ad

You'll need to get the one with "3D support" to get higher refresh rates. I don't know how high NVIDIA will allow you to go with that adapter, but AMD users have been able to get around 75 Hz (300 MHz pixel clock) with 8-bit color and 100 Hz (400 MHz pixel clock) with 6-bit color. You probably won't be able to get 120 Hz with any adapter.

The other option is to use a second video card.
