NVIDIA Pascal Cards Have High DVI Pixel Clock Booting Problems

Here comes the second bug with NVIDIA’s latest GeForce GTX 1080 and GeForce GTX 1070 graphics cards, and this one is not isolated to just “Founders Edition” cards. Users of monitors with dual-link DVI connectors are noticing problems when booting into Windows with pixel clocks set higher than 330 MHz. You can boot into Windows with the default pixel clocks, and then once booted you can set the clocks back higher than 330 MHz and the display will work just fine. You just can’t booth with those settings from the start, and will have to revert to default settings each time you shut down or restart your machine.

One users who is gaming with a custom-design GeForce GTX 1070 notes that if the refresh rate of their 1440p monitor is set higher than 81 Hz (the highest refresh rate you can achieve with the pixel clock staying under 330 MHz) and the resolution of 2560 x 1440 his machine does not correctly boot into Windows. The Windows splash screen is replaced with flash color screens, and nothing beyond. The system BIOS screen does appear because it runs at a lower resolution. This problem has also been observed on custom-designed GeForce GTX 1080 cards, and has been replicated by users on the GeForce Forums.
