This is an EDID limitation. Detailed resolutions only have two decimal places. Use this to calculate the totals required for specific refresh rates: https://www.monitortests.com/pixelclock.php

EDIT:BTW this frequency is default with AMD GPUs, I check in powerstrip on 280x and 59.951 is default one. But after installing nvidia GTX1070 frequency goes to 59.950 and pixel cloack slightly under 154 (something like 153.99x). I notice that picture is better on 59.951 and pixel cloack 154.002 but can't set on nvidia. Like I said before I can set custom resolution with 59.951 and pixel clock at 154.002 in nvidia control panel but when go to game and back to desktop frequency goes back. So I tried CRU but can't setup 59.951Hz and pixel clock at 154.002, it rounds to 59.954 and pixel cloack 154.01

You didn't say you were having a picture problem. Based on the frequencies, I assume you're talking about a 1920x1200 @ 60 Hz monitor. If that's the case, the default pixel clock is supposed to be 154 MHz, but hardware variances can cause slight differences. Such a small difference wouldn't affect the picture.

What monitor is this? Are you using DVI or HDMI? What is the exact problem you're having with the picture and what changes do you see with the NVIDIA custom resolution?
