GeForce GTX "Pascal" Faces High DVI Pixel Clock Booting Problems
The second design flaw to hit the GeForce GTX 1080 and GTX 1070 after the fan revving bug, isn't confined to the reference "Founders Edition" cards, but affects all GTX 1080 and GTX 1070 cards. Users of monitors with dual-link DVI connectors are noticing problems in booting to Windows with pixel clocks set higher than 330 MHz. You can boot to windows at default pixel clocks, and when booted, set the refresh-rates (and conversely pixel clocks) higher than 330 MHz, and the display works fine, it's just that you can't boot with those settings, and will have to revert to default settings each time you shut down or restart your machine.
A user of a custom-design 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 pixel clock staying under 330 MHz) and the resolution at 2560 x 1440, the machine doesn't correctly boot into Windows. The splash screen is replaced with flash color screens, and nothing beyond. The system BIOS screen appears correctly (because it runs at low resolutions). The problem is also said to be observed on a custom-design GTX 1080, and has been replicated by other users on the GeForce Forums.

And then there is monitors with multiple inputs(i.e. BenQ XL2730Z 144Hz), which while have dl-dvi input does not support 1440p@144Hz over dvi(dp only).
here's what i wrote
"Hi will this card connect to a analogue monitor or do i have to purchase an adaptor"
they replied "The outputs are Digital only and it states on EVGA spec sheet for the card " Please do not connect to "DVI to VGA" adapter." Hope this helps."
i have a 21 inch sun microsystems crt monitor ( ye ye it's old ) but it does for me, the card i asked the question about was the
GeForce GTX 1080 FTW ACX 3.0 , so i gather they will be the same outputs on the classified
oh-well i didn't want to spend £700 on a graphics card anyway :(
as said though i still have this 21inch crt which i love to bits, so i might get a gtx 980 (i have a HD5870 at the mo) hopefully i can get one in the sales, saying that i haven't seen much movement in their prices yet
i can wait though, and might invest in a new monitor sometime in the near future, just means more of my savings gone :twitch:
This only occurs from 1080p@144 Hz and above resolutions/refresh rate yes? If you use 1080p@100 Hz or 1080p@120 Hz will the problem also occur?
<rant>Any gamer worth his kb/mouse knows that AMD has been the one consistently trying to push things forward with all their innovation on both the hardware & software aspects of gaming. All the while doing it with the smallest budget and the largest opposition, and not raping their customers in the process. I'm not saying AMD are/have been without any fault, but that is true of all things.</rant>
Just like AMD. It's always a matter of perspective. Does pixel over clocking affect me? Not at all. So I'm not bothered by an otherwise niche element. Is it only people who overclock specific monitors on a specific adapter? Yup.
So it it really a huge issue? Don't think so. Like all things, overclocking even when software supported isn't a guarantee, especially on a monitor.
I do think we require more tea cups though because this is a great over reaction party. Especially from those it doesn't affect.
Thanks much!
Also, apparently my monitor can be overclocked to 85Hz, but I get frame skipping at 61Hz on any interface while AMD users say the monitor is supposedly stutter-free when overclocked on their cards.
Still, disappointing to see it having issues. If the cable can carry it, the card should transmit it without having issues booting windows, period.
It's not a big issue, but it IS an issue, period.
