Nvidia GTX 1080 and 1070 Unable to Boot Correctly At High DVI Pixel Clock
Nvidia GeForce GTX 1080 and 1070 graphics cards have been available on the retail market for the past few weeks. Based on the latest 16nm FinFET process and the next generation Pascal architecture, both cards deliver a significant performance boost over the previous generation flagships, so they were bound to be a success in the high-end market segment.
The flagship GeForce GTX 1080 Founders Edition sold out almost everywhere within a few hours of its launch despite charging an extra $100 over the original MSRP of $599. But soon after users got the graphics card, there had been reports of fan revving issues which were affecting several consumers. Nvidia was quick to respond however; the company fixed the issue in its next GeForce driver update.
Now it seems that users of the GeForce GTX 1080 and 1070 are experiencing another issue relating to the DVI output at high frequencies, and this one is not limited to the Founders Edition, but affects all models.
Specifically, users of GTX 1080 and 1070 using dual-link DVI connectors could experience problems with booting in to Windows with pixel clocks set higher than 330 MHz. The issue was reported by a user on the GeForce Forums, and has since been replicated by others, too.
According to multiple reports, if the refresh rate of your dual-link DVI monitor exceeds 81 Hz (the highest number you can achieve with pixel clock staying under 330 MHz), you will be unable to boot in to Windows, and the splash screen is replaced with flash colors on your monitor.
The system BIOS screen appears correctly because it runs at low resolutions. The problem persists until the pixel clock returns to a number under 330 MHz.
If you run into this issue, simply use DisplayPort. If you can’t, the other way around is to boot into safe mode then reset your monitor refresh rate to a lower value (under 81 Hz) and continue. You’ll have to repeat this each time you shut down or restart your machine until Nvidia fixes the issue.
