Monitor won't OC with DP Adapter

[Tor Eivind]

Hi!
I recently bought a third new monitor to my setup. I have two 60hz monitors and one 144hz. My videocard have 1x HDMI output, 1x DVI output and 3x DP outputs.
What I have to do is run the 144hz with dual link DVI as this is better for this monitor (there's no DP connection to the monitor) and as I only have one HDMI output I need to use HDMI to DP on the other 60hz monitor.

I used to have only two monitors, one of them where connected directly with HDMI and one with HDMI/DVI adapter. Now I use HDMI/DP adapter on one of them. I had them overclocked to 79hz just fine. But with the DP adapter it seems like I cannot overclock to more than 70hz on that one monitor. Do you know why?

I am sorry for the bad formulation...

HDMI to DP may have lower maximum TMDS clock. How do you overclock them?

Thanks for clarifying. It’s not a big deal as those side monitors will only be used to browse and stream.

I overclock them by using the nVidia Control Panel. Let’s you customize resolution and refresh rate etc.

You may have better luck with CRU that lets you override some limits. There are some details in their forum that may help you, a bit tricky though for starters
