    I filled out the form for an RTX 4000, but if there are none left I will take an RTX 5000. Thank you.

    I've read through this whole thread, and am very interested in getting the RTX 5000, if you have it available.

    I wanted to check something first though. I see that driver modification and re-signing is necessary for the 7x30 series Precisions. Is this the case for the 7x40 laptops as well, or only the 7x30 series?

    If it is necessary for 7x40 series, I assume this means that I would need to modify and resign the driver every time NVIDIA releases a driver update. Is this correct?

    It only would be necessary if you dropped a RTX 5000 into a Precision 7X30 system.
    Note that @Ionising_Radiation's offer is only for RTX 5000 cards going into a 7530/7540. 7730/7740 use a different-sized card and there isn't a cheap source for those right now.

    So for a 7540 with a card in it already, I'd only need the new card and appropriate heatsink/paste, and then screws/cables etc.. could be reused, right?

    Hi, I filled out the form. It doesn't seem to let me PM you though, probably because I'm new here.

    I hope I am not committing some kind of treason with this comment lol.

    Thinkpad P53 RTX 5000 owner here. (I also own several Dell's and Alienwares if that makes it better, and they are still my favorite, and go-to brand usually). I was hoping to chime in with a query on the various different VBIOS versions floating around. Mine being the 15" model also came with an 80W VBIOS. I too tried flashing the Dell 110W one from the 7740, and got the same result. Black screen on bootup, and switching from discrete to hybrid graphics in BIOS did not help, just like you. I then flashed the Thinkpad P73 Vbios, at 90W, and had perfect success (obviously, since it is the same card from the same series workstation basically). And even with the inferior heat sink design in mine compared to Dells, I still have PLENTY of thermal headroom for more. I am repasted, so that helps too.

    I first thought that it was just due to the DGFF card being a totally different design that the VBIOS would simply not work with my soldered on card. But seeing as you had the same problem, then maybe the uploaded VBIOS was really corrupt? I can link you to the 90W version from the P73 if you want to give it a shot on yours. It is not as good as 110W, but still, every watt counts lol.

    Want to give it a try? For science!

    Edit: Just in case, here you go lol.

    Thanks for this! I just tried flashing the 90 W VBIOS, and no dice at all. I'm curious: maybe it's the nvflash version I'm using. Either that, or the Turing cards have additional security measures on top of the Pascal cards... but your cross-flash went just fine.

    Care to share which nvflash version you're using, and exactly what commands you enter to flash the VBIOS? Thanks!

    Definitely! It is a modified version that bypasses the ID check, just a sec I will see if I can share it. I can't remember which thread on here that I found it. It was one of the 2080 VBIOS threads. Maybe for the 51M. I will share it from my GDrive.

    Here ya go! Let me know how it works. My stock VBIOS, the 90W, and the 110W are all in the folder, along with a Word document on how to flash it. use the nvflash64 one.

    I filled out the form awhile back but had not heard anything. If there are cards still available, I would really like to order one.

    Once thing I noticed is, the Dell 110W cards have a higher VRAM clock than the Lenovo ones. I wonder if your 80W card had the same VRAM clocks as mine?
