Custom Resolution Utility (CRU)

[jak soro]

hey forum,

i got a new computer with a nvidia NVS 510 Graphics card, which by description should be able to do up to 4 monitors at 4k resolution at 60hz.
3840-2160 is selected automatically however no option higher than 30hz is possible. i tried adding with higher refresh rate on the CRU and also used the nvidia patch to disable the pixel clock limits but still not able increase the refresh rate.
mouse is not smooth enough at 30hz, if someone could help me please understand what the problem is, im not very expert, thank you.

i use displayport to connect the monitor, windows 10
