Custom Resolution Utility (CRU)

Hi i have the AOC 24G2U monitor and 5700 XT. While running it at 144hz, the GPU VRAM won't downclock itself. What i found through my research is that the monitor needs higher vertical blanking value, but the problem is if i increase that it will go out of the upper range of horizontal frequency and exceed pixel clock rate[this can be mitigated by decreasing the horizontal blanking] and cause the "out of range" black screen when running 3D app[sometimes it happens immediately if the values are too high]. So my question is -is it safe to increase the monitor max acceptable values for horizontal frequency and pixel clock rate. Right now the monitor is running with 158KHz h.freq and 325MHz pixel clock rate, while the maximal limits are 160KHz for h.freq and 330MHz for pixel clock rate. I would like to increase the first value by 5-10KHz to 170KHz and the second value by 15MHz to 340MHz -this will give me a leeway to increase the v.blanking to 1157[from 1098, that's just 18 blank pixel, extremely small and i can understand why vram is not downcloking]. Will this cause any adverse effects like damage to my monitor or shorten lifespan? If not, would there be any secondary problems like freesync issues, stutter, flicker?

Thanks in advance.
