    My GIGABYTE AERO 15 YC OLED which has a GeForce RTX 3080 came with nVIDIA's Resizable BAR disabled despite GIGABYTE mentioning this as a feature on their website.

    I contacted them about this and they informed me that there is indeed a VBIOS update to enable Resizable BAR however they will not send it to me and require me to RMA the laptop back to them which is not possible for me as I live on the other side of the world and I use this laptop every day for work.

    As I was doing HIDevolution's Tuning & Optimization Tweaks on one of our customer's laptop who happened to have the same exact model as I do but from a newer badge apparently. I checked the nVIDIA Control Panel System Information and was surprised to see that Resizable BAR was enabled on his laptop. So I used GPU-Z to save his VBIOS and flashed it on my laptop, rebooted and BAAM! Resizable BAR was enabled!

    If I am able to get the VBIOS for the RTX 3070 with Resizable BAR I will share it with you as well. The RTX 3060 already has it enabled.
    =====================================
    1) Download the GIGABYTE RTX 3080 VBIOS v94.04.3D.007B

    Make sure to right click on the file(s) you just downloaded, go to Properties, then hit Unblock from the bottom right as it may be blocked since it was downloaded from the internet, if you don't do this before you run the file or extract it, then it may not install correctly.

    To prevent this automatic blocking of files in the future so you don't have to go unblocking every file you download to ensure it runs properly, follow the guide in this thread:
    http://forum.notebookreview.com/threads/are-you-sure-you-want-to-run-this-file-yes-or-no.825668/


    2) Unzip the file and copy the VBIOS folder to the root of D: or if you don't have a D: Partition just copy it the root of C:

    3) Click Start > Windows System > Right click on Command Prompt > Run as Admin

    4) type d: then hit enter to go to the root of the D: Partition

    5) copy/paste the below command then hit enter:

    nvflash -il -6 GA104.rom

    6) Answer Y when prompted to proceed with the flash then hit Enter

    7) Reboot when prompted.

    Resizable BAR should now be enabled and you get the same 105W TGP as the original RTX 3080 VBIOS from GIGABYTE that was installed before.

    I would be grateful if you had someone with Aorus 15P XC with RTX 3070 130w.

    I asked people on reddit what they had Aorus 15P but somehow they can't answer...

    I guess I have to send my laptop for RMA. My service informed me they have vbios but they can't seend it to me... they promised to send my laptop back the same day

    I'll asks our production team when they are building one for a customer to check if the VBIOS has Resizable BAR enabled, I'll hook you up.

    Hi, Good job working this out. So strange that they would not just supply us with an update. i would much appreciate it if you could get the 3070 bios :)

    I will try to get it for the team (rtx3070). Thinking about sending in my laptop to be able to make a backup of the new VBIOS and upload it here.
    Since Gigabyte support let's us down, customers need to stick together!

    Please share the VBIOS when you can. I couldn't get it from our production team yet as we don't have any orders for this laptop yet.

    Hi Seba, Would the 130 watt bios work with the aero 15 too? I'm pretty sure the max is 105 of the box, so that would be really cool.

    @up Yes it will work but remember that you have different cooling 15p is 4mm thicker than the Aero and G series. In my laptop temperature of the gpu is around 75C during the game with cooling pad (without cooling pad i got 80C). So if you flash vbios 130w to your laptop you will have much higher temperatures. Tjmax for gpu series rtx 3000 is 86C.

    Aero and aorus G:

    You see difference?
