G73jh gpu 770m upgrade succcess

Hello.
So it can be confirmed that olding like G73jh can be upgraded to latest of nvidia gtx series. I must confess one thing though when thinking about this machine first thing that comes to mind is zombie
Becouse it involves merging 4mb bios file of g73jh with g73jw plus moding video bios to get standard mxm 3.0b gpu be recocgnised by system.
All this was neccessary becouse without bios mod there is not support for nvidia gpus in system bios but g73jw has neccessary callbacks and thus is involved in this mod. Even inside bios settings it is shown as g73jw now and all other programs like HWinfo shows it as that.
With original unmodded bios there is no backlight on internal lcd before windows log in screen is loaded and both fans are on full throttle constantly.
Under is some pictures and link to 3dmark11 score with standard clocks.

Nice to see the beast going still, the 770M has been friendly to non optimus machines so there was a good chance of it working (with that extra work you put in), the 780M likely wont.

I thought the power conservative 770M would be a good partner to this machine.

 

hello

I've got a G73JW and would like to upgrade it to 770m.

Would you be able to upload the vbios file plz?

Thanks.

 

It's not the vbios you need, it's the system bios with the vbios integrated.

 

What I must flast, when I want faster my 5870 in f73gh ?

 

Thanks Meaker.

Hi jmhdj, Could you upload the system bios with integrated new vbios plz? Thanks.

 

Its not that simple. As you have to flash part of bios that is normally never accessed by flashing with windows or asus easy flash utility. Its first 1.5mb partition that has to be modified containing EC firmware. Only way to access that part is by desoldering bios chip and programming it directly with soic8 flashing utility. So I am very hesitant to share this mod outhere..
In other words file is 4mb and not 2.5mb large and cant be flashed standard way.

 

I got a deep flash tool off of svet for MSI, if anyone has a contact at asus they could ask if there is a similar tool.

 

For last 3 years dealing with asus among other laptop manufacturers its easier to get kidneys from thoose service guys then actually get any help and not to speak about internal servicing software.

 

It would need someone on the inside to help yes.

 

:=)
Yes we need another Snowden now!!!

 

If only we had such links to all companies as it can really help to get that last 20% out of a system.

 

yeah how is that done? i wonder if it can be done with a GTX780?


i think original source: http://rog.asus.com/forum/showthread.php?44304-G73jh-770m-GPU-upgrade-success

 

You need an unpacker tool (the bios file is basically zipped), pick the out the vbios, edit it, re-place the original and re-package the bios.

 

then blind flash is required?

 

You could flash it with the old card in it, it will technically brick that setup due to the incorrect vbios (just don't even try to start it), swap the new card in and hopefully it should boot up.

 

cdoublejj can you elaborate on what you trying to do and exactly on which model?

 

so the new card doesn't needed a modded vbios? just the system bios?

I have a G73JH and instead of an 7970 or 8970 a GTX 770 or 780 would be nice. maybe should think less of these things. an AMD gpu should work at least okay under windows 7.

 

to get nvidia Cards work on g73jh is difficult thing. One would need to merge g73jw and g73jh bios to get nvida GPUs to work and I am talking about Whole bios not only partition that asus provides as Upgrade.

 

we already have g73jh unlocked bios? why doesn't some make combine and unlocked bios for nvidia cards and release it for every one?

 

It is not that simple. You can't unlock features that are not there at all like missing mxm structure for nvidia cards in g73jh unlocked bios or not. And simple fact that no one has done this yet tell's how easy or not is to do it.

 

i'm talking about combine 2 bios. if you make an nvidia capable bios using the stock bios you will LOOSE out! you see there exist a 3rd part bios with unlock features that are nice to have. IF one was to make an nvidia compatible bios i would use the current modded unlock bios as bases so you don't give up those feature in exchange for the nvidia compatibility but, instead have both nvidia compatibility and unlocked features.

is the MXM structure to complex to add and just have the JH work with both AMD and nvidia?

 

I see

 

Well it depends how it's implemented, the size of the chip and expected ROM etc.

 

bios rom size or vbios rom size or both?

 

You need a detailed understanding of how the bios is structured, if and how it detects what gpu is in (or if it's a dumb load) and if it can select a different bios depending on the card it finds. Then you need to ensure the bios is large enough to handle the extra bios files.

 

It is possible for sure as i have proven that with my g73jh and gtx 770m upgrade. But it is complicated mod that involves combining two different bioses and I am not talking about 2560kb files from asus but 4096kb that needs to be downloaded directly from bios chip itself. Plus flashing asus 770m vbios on new card as they are either form clevo/sager or dell/msi and their vbios is not compatible with how asus implements mxm structure in its bios. And if you are not lucky and new gpu has different type of memory chips then asus one then you need to fix that to in vbios or you get artifacts and bluscreens or video driver crashes.
To get all this right means you need good technical knowledge both hardware and firmware wise and probably dont need someone else to write you guide on how to do that.

 

so for the JH to not suck you'd have to be a super genius and reimplement and or rewrite most or all of the MXM structure to a more universal stand like sager and dell and clevo.

 

Or just be a bit clever and use work asus ingeniours already have done in asus g73jw bios and combine it with g73jh bios. Voil à

 

Asus just did not program in the flexibility as they never wanted users to change cards. So either you redirect to a different card or yes rewrite the thing lol.

 

from what i'm seeing/hearing in this thread is that, that is next to impossible or easier said than done. Personally i don't like asus laptops and i KNEW better than to get this but, i thought i was getting deal even though i knew all the known issues. i'd rather have a custom Power Notebooks machine but, that's off topic. a nice flexible unlock JH bios would be cool if it was possible.

 

I honestly myself cant see single one feature usefull with unlocked bios on g73jh. Can you mention me one please?
Besides that it is cool.

 

while it is true that i can't it's also true i haven't had time to study them and learn what they do. I could be wrong but, i think some of it can be used for tweaks for OC.

but, also fully MXM structure could mean simultaneous support for nvidia and AMT which could be considered an unlocking, unlocking support for more videos cards and every one can see how that is usefull.

 

If you list out all the unlocked features I can tell you if they help.

 

So... is it possible or not?
By possible I mean clear instructions how to do it even if it takes a programmator.
So far it looks like it isn't.

 

Hi, so after reading this thread I'd like to try upgrading my asus g73Jw GTX 460M with a GTX 560M (yeah I realize that in terms of GPU power there's very little benefit in doing so, but I have the new GPU anyway, and as a personal project I want to try it).

I've already physically installed it, fits fine. In terms of actually getting the system to recognize it, how will the system BIOS need to be modded? Shouldn't this be easier than attempts made with the JH model, as it was necessary to merge that BIOS with JW BIOS?

 

Have you tried just starting it?

 

Oh of course, it's not recognized by the system at all. I've tried updating the required Nvidia drivers for it, but since they can't detect the 560M, all of these installations fail (some error like "cannot detect required hardware"). The computer is stuck using the onboard VGA GPU. It's funny, because while device manager doesn't recognize the GPU, DriverToolkit does recognize it, it just says that the drivers for it are missing (and they can't be installed, either, as I mentioned above, the "cannot detect required hardware" error).


I am a total noobie at all of this stuff, and while I have looked into flashing the VBIOS, if the intended GPU isn't being detected, wouldn't I just end up flashing the onboard GPU which is currently in use? And obviously that wouldn't help me at all...


This is why I'm interested in learning more about this stuff. I understand that asus uses proprietary hardware... What does this mean exactly? Is the system BIOS deliberately ignoring any GPU that is not a GTX 460M, which is what it was built with?


I would like to make this pet project of mine work, but I'm at a loss on how to continue from here, any suggestions would be welcome.

 

Well I got it to work. As stated by the OP, you need to modify the .inf file of the latest driver you are trying to install for the new GPU. Worked for me anyway, although if anything my laptop is a bit slower and more unstable with the new GPU atm; I am working from a fresh install of windows 7 though, so more time will tell if this has really been a positive upgrade for my laptop or not.

 

I was about to say, yes you need to also disable driver signing in windows 8.

 

Hello, I have a question to you - what about G73JW laptop - is it possible to upgrade the GPU there and how it should be done ? BIOS modding necessary ?

 

The same principles apply, it can be done but there will be extensive work to do it.

 

Hello jmhdj, how are you? I have been searching for Asus G73sw gpu upgrade, i have a 675m from clevo but it says that i need to put a compatible mxm gpu. Can you help me ? Regards from Portugal

 

Anyone ? i need a v-bios, where i can find one ?

 

Have you checked over at tech inferno? That might be a tricky card to get a vbios for.

 

Thats the next step, i put the card on asus but it says in the screen that i need to have a compatible asus card and then i need to wait 30 seconds. My cousins upgraded their clevos GPU and send me their old gtx675m

 

Does it boot after the 30 seconds?

 

No, it reboots

 

Then you need a rather in depth knowledge of bios files to modify the system bios like the OP.
