Can We upgrade G73SW GPU?

[svl7]

aYeah, please send a pic, I'm curious. Bad news since this means I will need another adapater and more different chips in the future.

Cant attach picture via forums email service

Anyway chip is same as sop8 type only problems you would have is if you need to remove it. But with proper equipment thats not big problem. It can be replaced with sop8 type afterwards as it is easyer to solder.

[svl7]

Well, send me an email

[jmhdj]

LOL long day sorry... in sec

Done.

I've got my fingers crossed for you that the connector or 2D internal lcd will work (as a start.)

[jmhdj]

I did tested that before when I owed both g73jh and sw so I swapped screens just to see what happened. And sw showed picture on jh screen but jh didnt worked with sw screen. And with your 670m showing on internal lcd I think chances are good.

[jmhdj]

Update. Just tested with lvds 40pin cable from non 3D version and still no output on internal screen. Hwinfo monitor tab is empty. Installed atk package and tried to switch betwen screens with Fn+F8 picture on vga screen just blink fast but nothing happens.

[svl7]

Yeah, still need time to improve my mod.

well guys i´m just reading it, and it´s going in a good pace

Svl7 is doing an awesome job changing the bios and jmhdj testing!!

Good work guys, i wish i could help with something :/

[jmhdj]

I am almost finished with modding bios chip so it to can easily be removed for programming in case of bad flash. I think its worth to try and attack our problem from this side to. When I am finish with that then we will see if MMTool can do something in our favor. I really hope we can make this upgrade possible:) there are many, many g73sw users there that would be happy to be on pair with other gaming laptop brand users

Btw IshouldGo what bios version you got on your machine?

[IshouldGo]

I've got the American Megatrends G73Sw 205 bios. and my vbios is 70.24.44.00.00 Not Av

I'll let you know the minute I get a new vbios and can flash it. Not sure how to hexmod my own so trusting svl7 on this one.

[jmhdj]

I made full backup of sbios chip 4mb and looks like there is more data inside than in rom that is provided by asus. And MMTool loads it..

[IshouldGo]

FYI- So apparently my 670m is a clevo model after all, and not an msi (when I look up the vbios id on it).

[andrewff2]

hmm... no updates!!! are you guys alive??

[IshouldGo]

hmm... no updates!!! are you guys alive??

I'm patiently standing by awaiting svl7's hard work (vbios). (ok, not so patiently, but there's a much better chance of his working that whatever I might come up with...).

[jmhdj]

Hello i was busy whole day yesterday. As they say patience is virtue. Its not my strong side anyway

I did test some functions in sbios with AMIBcp but for no effect. I think If function is not implementet in bios then there is no callback to that function and thus no changes.

Prema recieved whole bios dump from chip and I hope that he can find something that can help us.

But I will still continue to fidle around as I can easily reflash both chips if something goes wrong.

[andrewff2]

well if you guys see, patience is something is a must because you need to test and test and test

I made this thread looking for someone who tried the changes or willing to try... And i waited for someone (jmhdj fall from the heavens). I hope this changes work for all of the G73sw users.

[IshouldGo]

while I'm waiting, I'm wondering if I could load the ASUS 670m vbios that they use on their 670m? assuming I can manage to get a hold of a copy of that vbios... what do you think? so it's for the G75 which is different from the G73sw, but....? (sighs) once again getting ahead of myself.... g'nite!

[jmhdj]

I have experimented with mmtool whole day today. And there were some extra menus that apeared in bios. So I tried to fiddle with them.

Those with acpi and pci functions but no matter what problem is still same. No picture on internal lcd and clocks are emberassing to say least .

Max frequency on core is 150mhz. I did got it to 235mhz once with nvidia inspector but dont remember what I did before that so I cant reproduce it again.

[svl7]

Sent you both an email, @IshouldGo, let me know in case you didn't get it.

[jmhdj]

Just tested new vbios. Black screen, caps/nmbr lock light is working so its not compleately dead.

[jmhdj]

Small progress forward

I downloaded bios of asus g75vx and extracted vbios from it. As we know g75vx has 670mx with 3gb vram so i was sceptic about that. But surprise pc booted and loaded windows with no problems. Even clocks work now 601mhz core on max and vram 1400mhz. It even dowclocking normally. Didnt test anything more than that jet. But weird thing that both gpuz and nvidia inspector still recognise it as 680m and read other information correctly. In bios vbios version is readed as 80.04.97.00.13 NG2G75. under is screenshot from gpuz.

But internal lcd is still black.

[svl7]

I actually know that this works, the first version I sent you was based on an Asus 670mx vbios, but the problem is the internal screen.

Did you try both versions?

[jmhdj]

Yes. Updated post above. But with your vbios core clock always locked at 150mhz core max
