Guide: Enable nVIDIA Resizable BAR on the AERO 15

Disclaimer: I am not responsible if you brick your machine. Please do this at your own risk

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!

 

I'm also sending mine in next week to get bios for rtx 3070 130w

 

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.

You see difference?

 

@up Very interesting. I've not noticed my card getting too hot believe it or not (max around 75), even though i've got an overclock on it right now. I also have it on a cooling pad, so i think there is a chance i can crank the fans and get the extra wattage going.

My cpu however gets to the 90s on occasion, which heats up the whole cooling system. If i could undervolt the cpu (with unlocked bios in the future when my warranty ends ) and crank up the gpu with that vbios, it might be a way to squeeze a bit more juice out of the machine in games. either way, even if it does thermal throttle a bit, i would really just like to have resizable bar and advanced optimus.

 

@twicken i will try to get the rtx3070 vbios for 105w

rma has not replied yet, though.
rma support has very bad ratings in germany, hopefully they are as quick as poland though

 

If anyone can get the resize bios for the Aorus 15G XC 3070 it would be amazing. Big fan of my system just want all the features i can get.

 

@hongkongphooey99 should be compatible with my aero 15 oled xc VBIOS. But check below if your current VBIOS matches with mine
94.04.3D.00.3A (no resizable bar)

and just in case any flashing gone wrong, I'm leaving this here: backup of my current VBIOS WITHOUT resizable-bar enabled
https://www.techpowerup.com/vgabios/232543/232543

 

How do i check if my current one matches? i have a file in my C drive called ship id the vbios version on that is 94.04.3D.00.43 but i got no clue if thats up to date at all

 

check nVIDIA Control Panel System Information you can see the device id, vbios version and resizable bar enabled/disabled here
but as far as i can see, it's a slightly different vbios than mine, but device ID matches.
I'm quite sure that mine should work with yours as well, but I'm no expert here.

 

You have vbios from rtx 3070 130w. Where did you get it? Upload this file I can check what is this.

 

i found his version on techradar just search for his vbios number.

but from the date it was released this can't be the one you're looking for @seba84_2005

 

oh my, after 5 working days german RMA finally replied just to tell me that i can download bios from the website... gosh, i've asked for VBIOS and resizable-bar.
they have no clue what I'm talking about, i guess. bit worried to send it to these fools...

 

That's really bad. at least they replied though, its been two weeks and i've heard nothing from their e support. (I'm in australia btw).

 

well i already left esupport behind, now i want to send it in for the update...

 

Does anybody know if flashing the rtx 3070 from the aero XC with this vbios ( https://www.techpowerup.com/vgabios/232160/232160) will directly mux the internal display with the nvidia gpu and disable optimus?

Thanks

 

no, I don't think so. I believe he ment that gpu-z only shows enabled when you have switched to mux already, that's why nvidia system info is more accurate.
but if you're trying the vbios succesfully, I would use it as well.
I'm currently stuck at RMA and very annoyed by their "support"

 

so the clevo update should work I guess, but I get a warning that image pci subsystem ID doesn't match with adapter pci subsystem. bit worried to update, now

 

@up only Device Id: 10DE 249D must be correct. I had a pci subsystem mismatch on my laptop too and vbios from clevo works perfect.

 

hey seba i got your pm for some reason i cant respond. but here are instructions for xmp unlock overclocking and realtime memory timings, dont mess with the timings, and set the profile to XMP if you have XMP memory, if not it will automatically run the highest profile. Also has there been any updates on an aorus 15G XC 3070 resize bar bios?

 

@Unfortunately I don't have ram with XMP. I thought you had some manual settings for memory. I know this about the XMP profile.

For vbios You can try flash from clevo if you have same Device Id: 10DE 249D

Nv control panel, Help, Sys info:

 

seems like it's working properly with the clevo vbios. resizable-bar is now finally enabled. thanks @seba84_2005 and thanks for nothing gigabyte

so I can confirm, you can use clevo vbios for aero 15 oled xc https://www.techpowerup.com/vgabios/232160/232160
simply follow the steps as described by @Spartan@HIDevolution

in case anything goes wrong, you can download my backup of the former vbios without resizable-bar enabled
https://www.techpowerup.com/vgabios/232543/232543

 

@hongkongphooey99 I think Aorus 15G XC 3070 105w have same gpu as Aero 15 Oled XC 105w. So go and try flash yours vbios from clevo

https://www.gigabyte.com/WebPage/784/

 

i have the same id Ill try it out thanks for the tip. also check in the bios i think factory ram has an xmp profile. My factory crucial one had an xmp profile for 3200mhz

 

@up i have sasmung 2x16 dual rank memory. They don't have xmp. Cricial have single rank, but have XMP. https://abload.de/img/20210418_115943p2kkr.jpg

 

uh so i flashed the bios and my laptops screen is just black. Like all my connected displays still work but it just wont detect my laptops display anyomore. That happen to anyone else?

 

i have a bios backup just incase but i really want to get this bios working

 

ok, that's bad. I'm very sorry. works fine for me with the amoled samsung 4k display.

there is also a backup of your old bios on techradar. just search for 94.04.3D.00.43 in google, in case yours is corrupted

 

i made a backup of my own just incase thankfully but it fixed itself when i flashed back. the clevo bios enables resize bar but for some reason the actual laptop screen is just not detected

 

@hongkongphooey99 what is Yours device id?

 

10DE 249D 76C51458 the clevo bios works and boots just the laptop display is complete whacked out and seems to not even boot on which is odd. Sucks too since resize bar was enabled lol

 

glad you could restore it. sooner or later someone will provide the correct vbios from gigabyte, hopefully.

at least we have one more information for fellow owners.

the vbios works for aero 15 oled xc but not for the aorus equivalent and it might be troublesome for aero 15xc fhd version as well

 

Sadly :/

 

Try other vbios with same device id:

HP
https://www.techpowerup.com/vgabios/232235/232235

ASUS
https://www.techpowerup.com/vgabios/229956/229956

MSI:
Latest vbios form GS66 94.04.3F.00.54
https://www.msi.com/Laptop/support/GS66-Stealth-10UX?sub_product=GS66-Stealth-10UG#down-bios

 

these seem to have lower wattage though?!

 

Yes. Check gpu boost clock all have 1290Mhz. This is max 105w gpu.

 

just saying, really not an expert here, learned so much the last few days from you guys.
but i believe someone, maybe @Spartan@HIDevolution installed a third party one and got lower wattage reported afterwards.

 

Ill just wait until some other become available down the line for my exact wattage

 

Hi all, Thank you for finding that bios for the 3070. I will attempt the flashing soon too, as i have the XC oled version. One question though. What's going on with advanced optimus? will that bios enable it? I'm interested in this feature because i intend to get a TB3 dock to drive 2 external monitors with Gsync. As far as i understand, you can only obtain Gysnc through the TB3 port with advanced optimus?

 

no, the vbios update only enables resizable-bar, no other changes detected.

 

Thanks. If someone has access to a TB3 dock, i'd be interested to know if the nvidia card will go through TB and support gsync without advanced optimus. I mean advanced optimus was also a listed feature as well as resizable bar, so i still don't think this is acceptable.

 

is it possible to flash aorus 15p bios onto aorus 15g?

 

Well, are you sure? I don't see it anywhere on the gigabyte website. I can only see it listed in some reviews.

 

@up from my aorus 15p spec:

There is no advanced optimus. There is a mux switch and that is not mentioned.
