GTX 10 Series can't boot correctly past 330 MHz DL-DVI pixel clock
  1 / 9    
I have a Gigabyte G1 Gaming GTX 1070, and if the refresh rate on my monitor exceeds 81 Hz (the highest number achievable while staying under 330 MHz pixel clock), I am unable to boot into windows because the welcome screen is replaced by flashing colors on my monitor. I am unable to boot into Windows until my pixel clock returns to a number under 330 MHz, but the BIOS is unaffected. If I load into Windows at below a 330 MHz pixel clock, and then change my refresh rate in Windows back to 120 Hz, I have no problems. The problem is exclusively when booting into windows at higher than a 330 MHz pixel clock using DL-DVI. My friend with an MSI Gaming X GTX 1080 has the exact same problem. Both of us have no issue while using Maxwell GPUs. I have seen several more people on the Overclock.net forums with the same issue, and all of them own Pascal GPUs. I am using the Hotfix 368.51 driver, but the issue exists on the previous two Pascal drivers I have tried.

Having the same problem with EVGA 1080.

This issue is easy to reproduce and effects everyone with a monitor that exceeds a 330 MHz pixel clock over DL-DVI. I really hope NVIDIA looks into this, as I can't use my monitor at it's highest refresh rate until the issue is fixed.

Can you state your connected display, as it will be required for reproducing the issue.

QNIX QX2710. I assume it could be reproduced on any DL-DVI display that surpasses a 330 MHz pixel clock, but most monitors with a pixel clock of 330 or higher use something like Displayport. My monitor can only connect via DL-DVI, unfortunately. It has nothing to do with the particular display, though, but how DL-DVI works on Pascal. You'll probably find that most people with this issue are using this display, however, as it is one of the few that exceeds a 330 MHz pixel clock over DL-DVI. Pretty much the only displays that surpass this value are 1440p 120 Hz+, or 4k 60 Hz+, and only a small number of these displays use DL-DVI. This same display worked perfectly at 120 Hz the day before I installed my new 1070, and also worked for a friend the day before he installed a new 1080. I just put my old 970 back in my case, clocked my monitor at 120 Hz, and it works perfectly. The problem is definitely with Pascal. Pixel clocks higher than 330 work perfectly once Windows has been loaded, but not before. The issue is definitely related to pixel clock, as it is only reproducible when passing a pixel clock of 330 MHz.

Im having the exact same issue. I can get to 80hz and maybe slightly above that but as soon as i reach 330mhz pixel clock it crashes at start. Using a GTX 1070 with a QNIX QX2710 over DL-DVI.

I am also having the same issue. Pixel clock at 330mhz or greater causes display issues on boot. Once I'm booted into windows, I can raise the pixel clock above 330mhz without any issues. GTX 1070FE purchased directly from NVIDIA.

I have a QNIX as well and have a 1070 on back order atm. It would be nice to have this problem resolved before my card arrives. I've seen numerous reports of this issue on Overclock.net and a couple of reports on the EVGA forums as well.

I have a 1070 and an X-star monitor (basically the same as the Qnix but different branding) and I have this issue as well. I'm using the X-star as my main monitor using DL-DVI and a 1080p monitor as the 2nd display. If I have the monitor overclocked, I get the color cycling on the X-star, but the 1080p display works just fine. This only starts after the initial Windows loading screen. If I unplug the 1080p display and plug it back in, both monitors work and the overclock is still active. Is anyone else using dual monitors as well?

Same problem here as well. Can't get past 330 MHz using an ASUS GTX 1080 STRIX.

I have 2x 1080 in SLI. QNIX QX2710LED monitor hooked up to the DVI output and an AMH A409U monitor hooked up via Display Port. I encounter the same issue as reported above when I boot up. Glad I found this thread before I decided to RMA the card...

Same problem with my 1070 FE and QNIX QX2710. Would be great if this could be fixed by a driver update.
