The limit is 165 MHz pixel clock, but it should send a dual-link signal beyond that, which the monitor probably can't handle without the patch. "LCD reduced" keeps the pixel clock from going above 165 MHz at 74 Hz. It sounds like there might be another limit that only affects RTX cards. Does your RTX 2060 have a DVI port or are you using an adapter?

Old quote I know, but I just bought a 2060 Super with a DVI port (EVGA 08G-P4-3067-KR) and I'm running into the same issue. Using a Catleap monitor that I've been running at 120hz for 5 years (using an R9 290X, your ATI patcher, and CRU) and the same dual-link DVI cable.

Before installing the new card I removed the custom profile from CRU and uninstalled the AMD drivers. After I installed the card I installed the latest Nvidia drivers (445.87), successfully patched all of the values, and restarted. I then added a new profile via CRU, but the monitor just goes black (but backlight on, so the monitor is not losing/refusing the signal) if I try to apply anything above 60hz -- even 80hz, which falls below the stock 330mhz limit, does not work. Same behavior if I use Nvidia Control Panel instead of CRU to create the custom resolution.

I'm about to try the 442.50 driver since that's what you stated for this patcher version, but do you have any other ideas?

Thanks!

EDIT: Same behavior with 442.50. I just tried 70hz, which at least sends something to the display but flickers like hell, while 71mhz and higher are black. Also same behavior using "LCD Reduced" in CRU.

EDIT #2: Well, if I run DDU, restart, reinstall 445.87, patch values, and use Nvidia Control Panel to create the custom resolution, it works....exactly once. If I restart the computer, it goes back to the same behavior and Windows starts with that monitor blacked out and won't show anything other than 60hz until I run DDU and do the whole process again.
