    Looking for some guidance- I purchased a GTX 1070 off eBay a few weeks ago, installed it in my P750DM-G and did not get a screen at all to even get into the MB Bios. I have the 4K, 60Hz screen. Sent it back and ordered a new one off Amazon figuring the return process would be easier, and yet again I have no screen. So, now I'm thinking it's something I'm not prepping on the laptop. It's on the latest stock Clevo MB Bios, and I haven't seen this raised as an issue in any other threads from people that have done this upgrade, just info about modifying the INF files. Would appreciate any suggestions before I send back and get a 3rd card, which at this point I'm assuming won't work either.

    Upgrade from what exactly?

    You need a Clevo bios that has the 1070 added.
    You need a Clevo vBios depending on G-Sync or Non G-Sync.
    You may also need the 1070 heat sink if you dont already have it.
    And sending back for a 3rd will net the exact same results....

    I currently have a 980M. When I put that in and replaced my stock 970M, I was able to flash the vBios from within windows (so it did boot with the wrong vBios), and my laptop does have an upgraded heatsync and the larger power supply. It looks like the key issue is the MB Bios. Right now the Prema Bios is not available, but I have seen this thread: http://forum.notebookreview.com/thr...clevo-laptops-rtx-cards-now-supported.825558/
    However, it’s not clear to me if I should only use that bios if I’m also updating my processor and willing to do hardware mods (which I’m trying to avoid). As well, I don’t have a UEFI version of Windows 10 installed so I’m not doing UEFI boot, if that matters. I guess I need to start with some direction on where to look for a MB bios or if the one I linked above is a good route to take. I’ve searched for a modded bios in the past, but only found one I was comfortable trying and the flash utility just crashed, so if I can find the name of that one I’ll post it just to rule one out.

    Hummm, I have never tried any of those bios files before so I can not speak on the validity of them.
    The Prema bios has been profected as in the whole bios works. And when it crashes he knows how to fix it from scratch...
    As long as you still have the other card, you are fine. Swap cards and try flashing the bios.(But i would do quite a lot of reading first! And also understand the mechanics and having a backup plan to recover) Then swap cards and see if it shows up. You are going to need it if you plan on running anything higher than a 6700K

    Is there any way to even buy Prema’s bios right now? The page on his website doesn’t have a purchase or download option and I understand all the download links have been scrubbed. The link I posted refers to needing a larger bios chip than stock, so I don’t think I’d try to go that route.

    Good catch, thank you. I've actually searched for and pinned several threads talking about this specific upgrade. Every one mentions needing to do a INF File Mod, some mention vBios, none mention needing a modded MB Bios, which is why I figured the first card was just broken. I think it should still boot without the correct vBios, as my 980M definitely came with a non-Clevo Bios and booted fine. I'm not going to be able to flash it without getting a screen first anyway.

    Hey Brad how's it going ... I'll do your .inf mod if you need help . This card will work in your system and very well in fact. Do you have TeamViewer?
