Cannot go past 146hz on Lenovo Legion7 laptop using CRU

[ToastyX]

You didn't say what happens when you try to go past 146.377 Hz. If you mean the refresh rate turns red, the screenshot shows the pixel clock is 655.35 MHz, which is the EDID limit. To add refresh rates with higher pixel clocks, you need to add it in a DisplayID extension block. You don't need the patcher.
